Coloration of the skin.
Coloration or discoloration of a part by a pigment.
Insoluble polymers of TYROSINE derivatives found in and causing darkness in skin (SKIN PIGMENTATION), hair, and feathers providing protection against SUNBURN induced by SUNLIGHT. CAROTENES contribute yellow and red coloration.
Melanin-containing organelles found in melanocytes and melanophores.
Mammalian pigment cells that produce MELANINS, pigments found mainly in the EPIDERMIS, but also in the eyes and the hair, by a process called melanogenesis. Coloration can be altered by the number of melanocytes or the amount of pigment produced and stored in the organelles called MELANOSOMES. The large non-mammalian melanin-containing cells are called MELANOPHORES.
Excessive pigmentation of the skin, usually as a result of increased epidermal or dermal melanin pigmentation, hypermelanosis. Hyperpigmentation can be localized or generalized. The condition may arise from exposure to light, chemicals or other substances, or from a primary metabolic imbalance.
The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
Irradiation directly from the sun.
An enzyme of the oxidoreductase class that catalyzes the reaction between L-tyrosine, L-dopa, and oxygen to yield L-dopa, dopaquinone, and water. It is a copper protein that acts also on catechols, catalyzing some of the same reactions as CATECHOL OXIDASE. EC
A melanocortin receptor subtype found primarily in MELANOCYTES. It shows specificity for ALPHA-MSH and ADRENOCORTICOTROPIC HORMONE. Loss of function mutations of the type 1 melanocortin receptor account for the majority of red hair and fair skin recessive traits in human.
Color of the iris.
That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
The functions of the skin in the human and animal body. It includes the pigmentation of the skin.
A type I cAMP-dependent protein kinase regulatory subunit that plays a role in confering CYCLIC AMP activation of protein kinase activity. It has a lower affinity for cAMP than the CYCLIC-AMP-DEPENDENT PROTEIN KINASE RIBETA SUBUNIT.
A condition caused by a deficiency or a loss of melanin pigmentation in the epidermis, also known as hypomelanosis. Hypopigmentation can be localized or generalized, and may result from genetic defects, trauma, inflammation, or infections.
Redness of the skin produced by congestion of the capillaries. This condition may result from a variety of causes.
The large pigment cells of fish, amphibia, reptiles and many invertebrates which actively disperse and aggregate their pigment granules. These cells include MELANOPHORES, erythrophores, xanthophores, leucophores and iridiophores. (In algae, chromatophores refer to CHLOROPLASTS. In phototrophic bacteria chromatophores refer to membranous organelles (BACTERIAL CHROMATOPHORES).)
General term for a number of inherited defects of amino acid metabolism in which there is a deficiency or absence of pigment in the eyes, skin, or hair.
A 13-amino acid peptide derived from proteolytic cleavage of ADRENOCORTICOTROPIC HORMONE, the N-terminal segment of ACTH. ACTH (1-13) is amidated at the C-terminal to form ACTH (1-13)NH2 which in turn is acetylated to form alpha-MSH in the secretory granules. Alpha-MSH stimulates the synthesis and distribution of MELANIN in MELANOCYTES in mammals and MELANOPHORES in lower vertebrates.
Chromatophores (large pigment cells of fish, amphibia, reptiles and many invertebrates) which contain melanin. Short term color changes are brought about by an active redistribution of the melanophores pigment containing organelles (MELANOSOMES). Mammals do not have melanophores; however they have retained smaller pigment cells known as MELANOCYTES.
A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
A fat-soluble riminophenazine dye used for the treatment of leprosy. It has been used investigationally in combination with other antimycobacterial drugs to treat Mycobacterium avium infections in AIDS patients. Clofazimine also has a marked anti-inflammatory effect and is given to control the leprosy reaction, erythema nodosum leprosum. (From AMA Drug Evaluations Annual, 1993, p1619)
A group of autosomal dominant diseases characterized by the combined occurrence of tumors involving two or more ENDOCRINE GLANDS that secrete PEPTIDE HORMONES or AMINES. These neoplasias are often benign but can be malignant. They are classified by the endocrine glands involved and the degree of aggressiveness. The two major forms are MEN1 and MEN2 with gene mutations on CHROMOSOME 11 and CHROMOSOME 10, respectively.
Color of hair or fur.
A predominantly X-linked recessive syndrome characterized by a triad of reticular skin pigmentation, nail dystrophy and leukoplakia of mucous membranes. Oral and dental abnormalities may also be present. Complications are a predisposition to malignancy and bone marrow involvement with pancytopenia. (from Int J Paediatr Dent 2000 Dec;10(4):328-34) The X-linked form is also known as Zinsser-Cole-Engman syndrome and involves the gene which encodes a highly conserved protein called dyskerin.
A disorder consisting of areas of macular depigmentation, commonly on extensor aspects of extremities, on the face or neck, and in skin folds. Age of onset is often in young adulthood and the condition tends to progress gradually with lesions enlarging and extending until a quiescent state is reached.
Pathological processes of the ADRENAL CORTEX.
A benign neoplasm derived from connective tissue, consisting chiefly of polyhedral and stellate cells that are loosely embedded in a soft mucoid matrix, thereby resembling primitive mesenchymal tissue. It occurs frequently intramuscularly where it may be mistaken for a sarcoma. It appears also in the jaws and the skin. (From Stedman, 25th ed)
A vitamin that includes both CHOLECALCIFEROLS and ERGOCALCIFEROLS, which have the common effect of preventing or curing RICKETS in animals. It can also be viewed as a hormone since it can be formed in SKIN by action of ULTRAVIOLET RAYS upon the precursors, 7-dehydrocholesterol and ERGOSTEROL, and acts on VITAMIN D RECEPTORS to regulate CALCIUM in opposition to PARATHYROID HORMONE.
The process of aging due to changes in the structure and elasticity of the skin over time. It may be a part of physiological aging or it may be due to the effects of ultraviolet radiation, usually through exposure to sunlight.
Tumors or cancer of the SKIN.
Membrane transporters that co-transport two or more dissimilar molecules in the opposite direction across a membrane. Usually the transport of one ion or molecule is against its electrochemical gradient and is "powered" by the movement of another ion or molecule with its electrochemical gradient.
Epidermal cells which synthesize keratin and undergo characteristic changes as they move upward from the basal layers of the epidermis to the cornified (horny) layer of the skin. Successive stages of differentiation of the keratinocytes forming the epidermal layers are basal cell, spinous or prickle cell, and the granular cell.
The external, nonvascular layer of the skin. It is made up, from within outward, of five layers of EPITHELIUM: (1) basal layer (stratum basale epidermidis); (2) spinous layer (stratum spinosum epidermidis); (3) granular layer (stratum granulosum epidermidis); (4) clear layer (stratum lucidum epidermidis); and (5) horny layer (stratum corneum epidermidis).
Any normal or abnormal coloring matter in PLANTS; ANIMALS or micro-organisms.
A secreted protein of approximately 131 amino acids (depending on species) that regulates the synthesis of eumelanin (brown/black) pigments in MELANOCYTES.

Topical all-trans retinoic acid augments ultraviolet radiation-induced increases in activated melanocyte numbers in mice. (1/783)

We have previously shown that daily application of 0.05% retinoic acid to the backs of lightly pigmented, hairless HRA:Skh-2 mice increases melanogenesis resulting from exposure to solar-simulated ultraviolet radiation. In this study we show that as early as 1 wk following commencement of treatment, there is a 2- fold increase in the number of epidermal 3,4-dihydroxyphenylalanine positive melanocytes in retinoic acid and ultraviolet radiation treated HRA:Skh-2 mice compared with mice that received ultraviolet radiation only. This increased to a 2.9-fold difference by 6 wk. Retinoic acid also augmented ultraviolet radiation-stimulated melanogenesis, with a 4-fold increase being observed after only 2 wk. These findings were also seen in C57BL mice. Ultraviolet radiation and retinoic acid needed to be applied to the same skin site for the augmentation in melanocyte activation to occur. Ultraviolet B rather than ultraviolet A was mainly responsible for melanogenesis and the retinoic acid primarily increased ultraviolet B-induced melanogenesis. Furthermore, retinoic acid on it's own, in the absence of ultraviolet radiation caused a small but statistically significant increase in 3,4-dihydroxyphenylalanine positive melanocyte numbers and melanogenesis. Thus topical retinoic acid is a potent modulator of melanocyte activation. Alone it is able to increase the number of activated epidermal melanocytes and make melanocytes more sensitive to activation by ultraviolet B.  (+info)

High polymorphism at the human melanocortin 1 receptor locus. (2/783)

Variation in human skin/hair pigmentation is due to varied amounts of eumelanin (brown/black melanins) and phaeomelanin (red/yellow melanins) produced by the melanocytes. The melanocortin 1 receptor (MC1R) is a regulator of eu- and phaeomelanin production in the melanocytes, and MC1R mutations causing coat color changes are known in many mammals. We have sequenced the MC1R gene in 121 individuals sampled from world populations with an emphasis on Asian populations. We found variation at five nonsynonymous sites (resulting in the variants Arg67Gln, Asp84Glu, Val92Met, Arg151Cys, and Arg163Gln), but at only one synonymous site (A942G). Interestingly, the human consensus protein sequence is observed in all 25 African individuals studied, but at lower frequencies in the other populations examined, especially in East and Southeast Asians. The Arg163Gln variant is absent in the Africans studied, almost absent in Europeans, and at a low frequency (7%) in Indians, but is at an exceptionally high frequency (70%) in East and Southeast Asians. The MC1R gene in common and pygmy chimpanzees, gorilla, orangutan, and baboon was sequenced to study the evolution of MC1R. The ancestral human MC1R sequence is identical to the human consensus protein sequence, while MC1R varies considerably among higher primates. A comparison of the rates of substitution in genes in the melanocortin receptor family indicates that MC1R has evolved the fastest. In addition, the nucleotide diversity at the MC1R locus is shown to be several times higher than the average nucleotide diversity in human populations, possibly due to diversifying selection.  (+info)

Skin pigmentary anomalies and mosaicism for an acentric marker chromosome originating from 3q. (3/783)

We report on a 22 year old man with hyperpigmentation distributed along the lines of Blaschko in whom cytogenetic analysis showed mosaicism for an unusual supernumerary marker chromosome. The patient was of normal intelligence and was not dysmorphic. The marker was present in 30% of his lymphocytes and in 6% of his skin fibroblasts from a dark area, while fibroblasts from a light area showed a normal karyotype, 46,XY. We have identified the origin of the marker using fluorescence in situ hybridisation (FISH) with whole chromosome painting probes and YAC specific clones. The marker was found to consist of duplicated chromosome material from the distal part of chromosome 3q and was interpreted as inv dup(3)(qter-->q27.1::q27.1-->qter). Hence, this marker did not include any known centromeric region and no alpha satellite DNA could be detected at the site of the primary constriction. The patient was therefore tetrasomic for 3q27-q29 in the cells containing the marker chromosome. We postulate that, in our case, pigmentary anomalies may result directly from the gain of specific pigmentation genes localised on chromosome 3q.  (+info)

alyron, an insertional mutation affecting early neural crest development in zebrafish. (4/783)

alyronz12 (aln) is a recessive lethal mutation that affects early stages of neural crest development in the zebrafish. alyron appears to be an insertional mutation as the mutation was generated following microinjection of plasmid DNA into one-cell embryos and the stably integrated transgenic sequences are closely linked to the mutation. The insertion site harbors multiple copies of the plasmid sequence that have experienced complex rearrangements. Host-insert junction fragments have been molecularly cloned and host sequences adjacent to the transgene have been used to map the mutation to the distal arm of linkage group 15. alyron function is required cell-autonomously in the neural crest lineage. alyron mutants have a severe but not complete deficit of premigratory neural crest as judged by reduced expression of several markers associated with early stages of neural crest development. Lack of premigratory neural crest is likely to account for the two most conspicuous characteristics of alyron mutants: the absence of body pigmentation and the inability to affect blood circulation. The neural crest phenotype of alyron mutants resembles that observed in mouse mutants that lack Pax-3 or both Wnt-1 and Wnt-3a function, and expression of the zebrafish homologues of these genes is greatly reduced in the dorsal neural keels of alyron mutants. In contrast, ventral neural keel identity appears unaffected. Given our findings that the mutation is unlinked to pax or wnt genes that have been described in the zebrafish, we propose that alyron is a novel gene function required for the specification and/or proliferative expansion of neural crest progenitors.  (+info)

An L1 element intronic insertion in the black-eyed white (Mitf[mi-bw]) gene: the loss of a single Mitf isoform responsible for the pigmentary defect and inner ear deafness. (5/783)

Waardenburg syndrome type 2 (WS2) is an autosomal dominant disorder characterized by a combination of pigmentary and auditory abnormalities. Approximately 20% of WS2 cases are associated with mutations in the gene encoding microphthalmia-associated transcription factor (MITF). MITF plays a critical role in the development of both neural-crest-derived melanocytes and optic cup-derived retinal pigmented epithelium (RPE); the loss of a functional Mitf in mice results in complete absence of all pigment cells, which in turn induces microphthalmia and inner ear deafness. The black-eyed white Mitf mi-bw homozygous mouse normally has a pigmented RPE but lacks melanocytes essential for the pigmentation of the body and hearing. We show here that Mitf mi-bw is caused by an insertion into intron 3 of a 7.2 kb novel L1 element, L1bw, which belongs to an actively retrotransposing TF subfamily. The L1bw insertion reduces the amount of mRNAs for two Mitf isoforms, Mitf-A and Mitf-H, by affecting their overall expression levels and pre-mRNA splicing patterns, while it abolishes mRNA expression of another isoform, Mitf-M, which is specifically expressed in neural-crest-derived melanocytes. The consequence of the L1 insertion in the black-eyed white Mitf mi-bw mouse is that the developmental programme for RPE cells proceeds normally, most likely because of the presence of residual, full-length Mitf-A and Mitf-H proteins, whereas the lack of Mitf-M results in loss of the melanocyte population. The results suggest that melanocyte development depends critically on a single Mitf isoform, Mitf-M, and raise the possibility that specific mutations affecting MITF-M, the human equivalent of Mitf-M, may be responsible for a subset of WS2 conditions.  (+info)

Combination immunotherapy of B16 melanoma using anti-cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) and granulocyte/macrophage colony-stimulating factor (GM-CSF)-producing vaccines induces rejection of subcutaneous and metastatic tumors accompanied by autoimmune depigmentation. (6/783)

We examined the effectiveness of cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) blockade, alone or in combination with a granulocyte/macrophage colony-stimulating factor (GM-CSF)-expressing tumor cell vaccine, on rejection of the highly tumorigenic, poorly immunogenic murine melanoma B16-BL6. Recently established tumors could be eradicated in 80% (68/85) of the cases using combination treatment, whereas each treatment by itself showed little or no effect. Tumor rejection was dependent on CD8(+) and NK1.1(+) cells but occurred irrespective of the presence of CD4(+) T cells. Mice surviving a primary challenge rejected a secondary challenge with B16-BL6 or the parental B16-F0 line. The same treatment regimen was found to be therapeutically effective against outgrowth of preestablished B16-F10 lung metastases, inducing long-term survival. Of all mice surviving B16-BL6 or B16-F10 tumors after combination treatment, 56% (38/68) developed depigmentation, starting at the site of vaccination or challenge and in most cases progressing to distant locations. Depigmentation was found to occur in CD4-depleted mice, strongly suggesting that the effect was mediated by CTLs. This study shows that CTLA-4 blockade provides a powerful tool to enhance T cell activation and memory against a poorly immunogenic spontaneous murine tumor and that this may involve recruitment of autoreactive T cells.  (+info)

Induction of melanoma in TPras transgenic mice. (7/783)

In order to study the oncogenesis of melanocytes, transgenic mouse lines were established that express a mutated human Ha-ras (TPras) gene in pigment producing cells. The ras transgenic mice exhibit an altered phenotype, including melanocytic hyperplasia and a muted agouti coat, indicative of hyperproliferative melanocytes. These mice and their wild-type littermates have been subjected to a variety of carcinogenesis protocols, including 7, 12-dimethylbenz-[a]anthracene (DMBA), 12-O-tetradecanoylphorbol-13-acetate (TPA) and UV radiation exposure. Topical DMBA treatment of TPras mice resulted in a high incidence of melanomas. Metastatic lesions were observed in skin, lungs and lymph nodes. TPA treatment of TPras mice induced a small number of papillomas but no nevi or melanomas. UV light exposures induced papillomas in negative littermate and melanomas in some albino TPras mice. These results show that melanocytes expressing an activated Ha-ras in the TPras transgenic mice are susceptible to induction of melanoma by DMBA.  (+info)

Dorsal skin color patterns among southern right whales (Eubalaena australis): genetic basis and evolutionary significance. (8/783)

Distribution and inheritance of dorsal skin color markings among two populations of southern right whales (Eubalaena australis) suggest that two genes influence dorsal skin color. The grey-morph and partial-grey-morph phenotypes (previously known as partial albino and grey-blaze, respectively) appear to be controlled by an X-linked gene, whereas the white blaze appears controlled by an autosomal gene (recessive phenotype). Calving intervals, calf size, and length of sighting history data suggest that partial-grey-morph, white-blaze, and black cows experience similar levels of reproductive success. Grey-morph cows (XgXg) are rare or absent in the two populations, but this was not unexpected given observed population frequencies of grey-morph males (XgY) and partial-grey-morph females (XGXg). The proportion of partial-grey-morph calves produced by black cows (XGXG) suggests that the reproductive success of grey-morph males was equal to that of black males, however, larger sample sizes are required to determine whether grey-morph males tend to have shorter sighting histories. The reproductive success of white-blaze males appeared similar to that of black males among whales off Argentina. There were significantly fewer white-blaze calves than expected off South Africa, which could be due to white-blaze males experiencing reduced reproductive success or to sighting blases that result in white-marked calves being misidentified as black calves. The relative frequencies of both types of dorsal color markings varied between the South African and Argentinian right whale populations, suggesting limited nuclear gene flow between these populations; analyses using other nuclear markers are under way to confirm the extent of gene flow.  (+info)

Dark skin is a naturally occurring human skin color that is rich in eumelanin pigments and having a dark color. People with relatively dark skin are referred to as brown, and those with very dark skin are often referred to as black, although this usage can be ambiguous in some countries where it is also used to specifically refer to different ethnic groups or populations. The evolution of dark skin is believed to have begun around 1.2 million years ago, in light-skinned early hominid species after they moved from the equatorial rainforest to the sunny savannas. In the heat of the savannas, better cooling mechanisms were required, which were achieved through the loss of body hair and development of more efficient perspiration. The loss of body hair led to the development of dark skin, which acted as a mechanism of natural selection against folate depletion, and to a lesser extent, DNA damage. The primary factor contributing to the evolution of dark skin was the breakdown of folate in reaction to ...

Human skin color ranges in variety from the darkest brown to the lightest hues. An individuals skin pigmentation is the result of genetics, being the product of both of the individuals biological parents genetic makeup. In evolution, skin pigmentation in human beings evolved by a process of natural selection primarily to regulate the amount of ultraviolet radiation penetrating the skin, controlling its biochemical effects. The actual skin color of different humans is affected by many substances, although the single most important substance is the pigment melanin. Melanin is produced within the skin in cells called melanocytes and it is the main determinant of the skin color of darker-skinned humans. The skin color of people with light skin is determined mainly by the bluish-white connective tissue under the dermis and by the hemoglobin circulating in the veins of the dermis. The red color underlying the skin becomes more visible, especially in the face, when, as consequence of physical ...
Pigmentation refers to colour, and skin pigmentation occurs when that colour is affected. Melanin is the pigment produced in your body that gives your skin its colour. There are certain cells that are responsible for making melanin and when these cells get damaged, melanin production is also disturbed. The resulting skin discoloration is then called a disorder. Some skin pigmentation disorders affect only some areas of your skin while others can affect your entire body. When your body produces too much melanin, the skin gets darker and is known as hyperpigmentation This happens when you stay in the sun for long periods of time and also during pregnancy. When the skin suffers a complete loss of pigment, it is known as depigmentation. Diseases such as vitiligo and albinism occur as a result of this.. Skin pigmentation disorders can be treated. Certain home remedies can also help in cases such as age spots and darkening of the skin due to the sun. Lightening creams are also available for age spots. ...

Skin pigmentation is one of the most variable phenotypic traits in humans. A non-synonymous substitution (rs1426654) in the third exon of SLC24A5 accounts for lighter skin in Europeans but not in East Asians. A previous genome-wide association study carried out in a heterogeneous sample of UK immigrants of South Asian descent suggested that this gene also contributes significantly to skin pigmentation variation among South Asians. In the present study, we have quantitatively assessed skin pigmentation for a largely homogeneous cohort of 1228 individuals from the Southern region of the Indian subcontinent. Our data confirm significant association of rs1426654 SNP with skin pigmentation, explaining about 27% of total phenotypic variation in the cohort studied. Our extensive survey of the polymorphism in 1573 individuals from 54 ethnic populations across the Indian subcontinent reveals wide presence of the derived-A allele, although the frequencies vary substantially among populations. We also show ...

Every woman wants to be considered to be beautiful. And since so much of this perception is based on their outward appearance, having a clear skin is a priority. While you could spend money on chemical peels, plastic surgery or various skincare products, eating your way to a better complexion is a much safer way to improve your skin..

Changing your diet to include fresh and raw foods with specific vitamins and minerals can greatly improve the condition of your skin..

However, their contribution to inter-individual variation at the population level is not well defined. To this end, we genotyped 3 single nucleotide polymorphisms (SNPs) in the MC1R gene (Arg67Gln, Gln163Arg, Val92Met) and 2 SNPs in the P gene (IVS13-15 and Gly780Gly) in 184 randomly ascertained Tibetan subjects, whose skin color was measured as a quantitative trait by reflective spectroscopy.

Skin color is a well-recognized adaptive trait and has been studied extensively in humans. Understanding the genetic basis of adaptation of skin color in various populations has many implications in human evolution and medicine. Impressive progress has been made recently to identify genes associated with skin color variation in a wide range of geographical and temporal populations. In this review, we discuss what is currently known about the genetics of skin color variation. We enumerated several cases of skin color adaptation in global modern humans and archaic hominins, and illustrated why, when, and how skin color adaptation occurred in different populations. Finally, we provided a summary of the candidate loci associated with pigmentation, which could be a valuable reference for further evolutionary and medical studies. Previous studies generally indicated a complex genetic mechanism underlying the skin color variation, expanding our understanding of the role of population demographic history and

Changes in the human pigmentary system can lead to imbalances in the distribution of melanin in the skin resulting in artefacts known as pigmented lesions. Our work takes as departing point biological data regarding human skin, the pigmentary system and the melanocytes life cycle and presents a reaction-diffusion model for the simulation of the shape features of human‐pigmented lesions. The simulation of such disorders has many applications in dermatology, for instance, to assist dermatologists in diagnosis and training related to pigmentation disorders. Our study focuses, however, on applications related to computer graphics. Thus, we also present a method to seamless blend the results of our simulation model in images of healthy human skin. In this context, our model contributes to the generation of more realistic skin textures and therefore more realistic human models. In order to assess the quality of our results, we measured and compared the characteristics of the shape of real and ...

Beauty comes in different forms and colors. There is indeed beauty in diversity. The definition of beauty varies from one person to another. That goes to show that while others claim that this or that skincare product works for them, it may be a different story for the other. The dilemma of people with lighter skin tone with darker skin tone is pretty much different especially when the talks about hyperpigmentation is on the spot light.. Hyperpigmentation is a common skin concern, though it may be a harmless condition, but the fact that it affects our self-esteem, gives as reason to look for treatments for it. It is a skin condition where patches of the skin become darker in color than the normal color of the surrounding skin. It happens when there is an excess melanin production, caused by everything from acne scars, environmental damage and hormone fluctuations.. Treating hyperpigmentation for people with darker skin may be a different - a total different story. Simply because, darker skin ...

THE PROBLEM: PIGMENTATION Pigmentation is caused by many things - hormones, sun damage and acne scarring are usually the biggest culprits. THE SOLUTION: While some forms of pigmentation can be concealed with a dab of foundation, its sometimes not so easily dealt with - and anyway, the aim is always to have a clear complexion, with or without make-up. First, remember that treating pigmentation is not an overnight process, but rather a commitment you make to caring for your skin. Start by ensuring you wear UV protection every day (sun exposure can aggravate and increase spots) and boost your exfoliation. Do this not with just a regular scrub; look for products containing alpha hydroxyl acids (AHAs), like glycolic and lactic acid, or beta hydroxyl acids (BHAs), such as salicylic acid, for a deep exfoliation. Follow with the application of serums and moisturisers that specifically target pigmentation concerns and keep at it. Give yourself at least six to eight weeks before you expect to see results ...

In microdermabrasion treatments the skin is blasted with tiny non allergenic crystals to remove the very top layers of skin.

Melanoma is the most aggressive type of skin cancer and is associated with environmental and genetic risk factors. It originates in melanocytes, the pigment-producing cells. Single nucleotide polymorphisms (SNPs) in pigmentation genes have been described in melanoma risk modulation, but knowledge in the field is still limited. In a case-control approach (107 cases and 119 controls), we investigated the effect of four pigmentation gene SNPs (TYR rs1126809, HERC2 rs1129038, SLC24A5 rs1426654, and SLC45A2 rs16891982) on melanoma risk in individuals from southern Brazil using a multivariate logistic regression model and multifactor dimensionality reduction (MDR) analysis. Two SNPs were associated with an increased risk of melanoma in a dominant model: rs1129038AA and rs1426654AA [OR = 2.094 (95% CI: 1.106-3.966), P = 2.3 10− 2 and OR = 7.126 (95% CI: 1.873-27.110), P = 4.0 10− 3, respectively]. SNP rs16891982CC was associated with a lower risk to melanoma development in a log-additive model when the
BACKGROUND: Acne vulgaris (acne) is prevalent in individuals with skin of color, often with more frequent sequelae than in patients with lighter skin color. It is important to determine if there are also differences in response to medications. OBJECTIVE: This study evaluated the efficacy and tolerability of once-daily dapsone gel, 7.5% in patients with acne, stratified by Fitzpatrick skin phototype. METHODS: Data were pooled from 2 identically designed, phase 3, randomized, double-blind, vehicle-controlled studies in patients aged 12 years and older with moderate acne. Patients applied dapsone gel, 7.5% or vehicle once daily for 12 weeks. Efficacy was evaluated using the Global Acne Assessment Score (GAAS), lesion counts, and Acne Symptom and Impact Scale (ASIS); adverse events (AEs) and tolerability were also assessed. RESULTS: This analysis included 2216 patients with skin phototypes I-III and 2111 with types IV-VI. Dapsone gel, 7.5% significantly improved acne severity versus vehicle in both skin

Few anti-pigmenting agents have been designed and developed according to their known hyperpigmentation mechanisms and corresponding intracellular signaling cascades. Most anti-pigmenting agents developed so far are mechanistically involved in the interruption of constitutional melanogenic mechanisms by which skin color is maintained at a normal and unstimulated level. Thus, owing to the difficulty of confining topical application to a specific hyperpigmented skin area, potent anti-pigmenting agents capable of attenuating the natural unstimulated pigmentation process have the risk of leading to hypopigmentation. Since intracellular signaling pathways within melanocytes do not function substantially in maintaining normal skin color and are activated only by environmental stimuli such as UV radiation, specifically down-regulating the activation of melanogenesis to the constitutive level would be an appropriate strategy to develop new potent anti-pigmenting agents with a low risk of hypopigmentation.

Sunlight, environmental factors and the natural passage of time all contribute to the development of dark spots, skin pigmentation and freckles. Your face, hands and chest are the first parts of the body to show signs of ageing because they receive so much sun exposure. Age spots, skin pigmentation and freckles are forms of pigmented lesions.

For Jennifer Eliogu, beauty has nothing to do with your complexion.. The Nollywood actress and singer shares her thoughts on the never ending topic - skin bleaching.. Yes you can roll your eyes, because every day, in every house, in every friend group, it is always being discussed.. In an interview with Punch, she shares that the trend may be because of insecurities.. I cannot speak for others because it depends on the reason why they want to be light-skinned. For some people, it is because they have skin pigmentation or the skin colour is not uniform and they want to change it. I dont know what their reasons are but I feel that for a dark-skinned person to want to tone their skin colour to be completely fair, it has to do with low self esteem. she says.. Jennifer who recently premiered the video for her song Fantasy, continues by saying If you are comfortable with the way you are, then you would not want to change your skin colour. If God wanted you to be fair, he would have made either of ...
The Republicans are so funny, when the economy is good you say lets all celebrate Cinco de Mayo, my brothers but when the economy is down its all your fault, you damn immigrant. When most Americans (with Latin America roots) go to the polls this November we will remember that the GOP has gone on a nationwide rant in proposing and passing several anti-immigration legislation (that our US Courts continue to strike down) and have continue to blame the immigrant for the flat economy or worse. We will remember who stands with us and who stands against us, so trying to stop it now is somewhat funny, but go ahead, you will not change our minds. Plus the more radical of the GOP are now attacking our Constitution and our Bill of Rights, in a misguided attempt to garner some much needed votes, they really are fools, and leading the GOP towards obscurity because they are no longer a party of ideas, just of empty suits. Your hate made you do it, in November; you will reap what you have sown. I wonder ...

By: Zama Ngcoya. While albinism is regarded as simply a genetic disorder in the Western world, in African cultures some still believe it is a curse from the greater forces.. Hlobisile Masinga says that to her it is a genetic skin disorder that makes you lighter than average individuals.. Masinga (19) from Ematikwe, a small township at Inanda, was diagnosed with albinism when she was born. She had inherited the genetic disorder from her mother, who is also an albino.. She said that in her childhood, she had no understanding of the condition.. Growing up, all I knew was that the sun hurt my skin and that I had poor vision. No one actually understood me besides my mother, the only other albino in my family, who unfortunately died when I was eight years old, she said.. Masinga also says she was given special treatment due to the color of her skin.. I had people who wanted to shake my hand, give me money or pity me just because I was lighter in complexion. It was annoying at first but as I ...
The 374F mutation in the SLC45A2 gene encoding the membrane associated transporter protein (MATP) has been suggested to be associated with skin color in Caucasians. In this synthesis, we collected the distribution of the 374F allele in 2910 unrelated subjects from 28 European and 4 North African populations. The highest allele frequency was observed in Denmark (0.98) and the lowest frequencies were observed in Tunisia (0.61) and in Algerian Mozabites (0.40). A significant decreasing latitudinal cline in 374F allele frequencies was observed, ranging from the north of West Europe to North Africa (R² = 0.6781). Key words: Human skin pigmentation, SLC45A2 gene, 374F mutation, membrane-associated transporter protein (MATP), population study, gradient of allele frequencies, West Europe and North Africa.

There are too many ignorant people here on SM! Indians and posters here just dont know whats in upper-caste Indians ancestry that causes them to be lighter-skinned on average because it would have nothing to do with staying indoors or outdoors. The darker skin of lower caste Indians isnt a suntan! Too many of you are taking for granted why the upper-castes are lighter skinned in the first place(if thats true. I havent been to India).. Now India has been invaded many times by Arabs, Persians, Mongolians etc. and their genes must have been absorbed into the upper caste and that might-be the reason behind upper castes lighter skin. The chocolate-licorice-cinnamon dark skin tones of India are from antiquity. Im tired of Indians and posters here having the insolence to equate dark-brown Indians with a suntan just because they have been placed on the bottom rungs of society and happen to be outdoors only due to their marginalization.

  • Hyperpigmentation is basically the increased production of melanin in the skin. (
  • One of the most common pigmentation problems in darker-skinned individuals is hyperpigmentation (or the darkening of the skin). (
  • Usually the result of some type of inflammation or injury to the skin, such as a cut, burn or scrape, hyperpigmentation produces darkened areas of the skin that can last months or years. (
  • Dr. Breadon noted that treatments for hyperpigmentation are based on whether or not the dark areas are confined to the surface of the skin or if they have penetrated to the deeper layers of the skin. (
  • Regular sunscreen use is vital to protect the skin from further hyperpigmentation. (
  • What Are Pigmentation, Hyperpigmentation & Hypopigmentation? (
  • As a result, parts of your skin may turn lighter (hypopigmentation) or darker (hyperpigmentation), both of which are recognisable skin conditions. (
  • What Causes Skin Pigmentation or Hyperpigmentation? (
  • Pigmentation, or hyperpigmentation as it is also known, can occur for a variety of reasons. (
  • Another very common skin disorder is known as post-inflammatory hyperpigmentation. (
  • While the causes and clinical presentation of post-inflammatory hyperpigmentation can vary, they are usually secondary to a traumatic incident to the affected area of the skin. (
  • Hyperpigmentation and advanced skin pigmentation treatment can be hard to find even though this is a rather common problem that affects plenty of different people around the world. (
  • Hyperpigmentation is the technical term used by skincare experts to describe uneven patches of discoloration on your skin. (
  • It'll only help target the hyperpigmentation on the surface of your skin, but it's a start. (
  • Because Asian skin becomes more inflamed with deeper acne pustules and papules, patients are often left with post-inflammatory hyperpigmentation (PIH), which refers to increased pigmentation or dark spots at the sites of inflammation. (
  • Dr. Kundu often recommends glycolic acid, salicylic acid or topical retinoids to her patients to remove the surface skin cells and improve both acne and hyperpigmentation. (
  • These pigmentation disorders can work either way - causing the skin to become darker (hyperpigmentation) or lighter (hypopigmentation). (
  • Skin hypopigmentation or hyperpigmentation still occurs. (
  • Hyperpigmentation is where dark spots appear on the skin. (
  • Certain medications can also cause hyperpigmentation, and post-inflammatory hyperpigmentation occurs when a blemish or other skin injury heals, leaving a discoloured mark behind. (
  • The treatment includes undergoing bleaching to lighten the skin ( most recommended in hyperpigmentation), chemical peels, and even laser surgery. (
  • Drug-induced pigmentation of the skin may occur as a consequence of drug administration, and the mechanism may be postinflammatory hyperpigmentation in some cases, but frequently is related to actual deposition of the offending drug in the skin.The incidence of this change varies, and depends on the type of medication involved. (
  • 5) Other factors such as heredity and hormonal changes can also lead to abnormal melanin output as we age, resulting in pigmentation disorders like melasma. (
  • Melasma is a difficult-to-treat pigmentation disorder that predominantly affects women.1415 In a randomized, double-blind, placebo-controlled trial, Rumex occidentalis extract was found to be as effective as the gold-standard skin-lightener hydroquinone in the treatment of melasma. (
  • 17) Other research supports the efficacy and safety of Rumex occidentalis extract for lightening skin discoloration in melasma patients. (
  • Some of the most common are pigmented birthmarks, macular stains, hemangiomas, port wine stains, while disorders include albinism, melasma, vitiligo and pigmentation loss due to skin damage. (
  • Pigmentation changes may also take place in those who have darker skin, as dark skin tends to have more melanin, which makes one more susceptible to a condition known as melasma. (
  • For years, hydroquinone has been considered by many to be the gold standard for treating pigmentation issues and is a key ingredient in our Obagi Nu-Derm ® System ,* which is ideal for treating age spots, dark spots, and melasma. (

  • Often referred to as the 'mask of pregnancy,' melasma is a skin condition marked by brown patches on areas such as the face, neck and arms that most often affects dark-skinned people and women in particular. (
  • With melasma, the skin can be affected in three different ways: on the epidermis (superficial layer), in the dermis (deep layer) or a mixture of both the epidermis and dermis. (
  • Dermatologists use a light device known as the Woods lamp, which shows skin diseases as specific colors, to determine how deep melasma has penetrated the skin. (
  • Pigmentation disorders such as melasma or chloasma arise from increased melanin in the lower layers of the skin and increased free melanin in the skin. (
  • Skin-bleaching agents are extremely helpful in lightening melasma and maintaining skin-lightening improvements. (
  • Effectively treat pigmentation, large pores, persistent breakouts, melasma, blackheads and uneven texture with Allies of Skin Mandelic Pigmentation Corrector Serum, a soothing overnight serum that helps to replenish moisture and strengthen the skin's natural barrier. (

  • Melasma is one common pigmentation concern that is characterized by patches of symmetrical, dark discoloration. (
  • Another common skin condition in Asians that can impact the appearance of the skin is melasma. (
  • Treatments for melasma include similar therapies used to treat pigmentation problems resulting from acne, such as bleaching agents, hydroquinone, topical retinoids and chemical peels. (
  • Melasma is one of the most difficult types of pigmentation to treat, as it has multiple internal and external triggers , including hormones, leaky gut syndrome, uncontrolled inflammation in the body, etc. (
  • Melasma is a skin condition where dark patches form on the sun-exposed areas of the body and most commonly on the face. (
  • Melasma, also called "chloasma", is a common skin condition in which light to dark brown patches of pigmentation develop on the face. (
  • Melasma is a chronic, acquired, pigmentary skin disorder characterised by symmetrical, brown pigmentation that usually affects the face. (

  • Sometimes skin disorders arise where there is solely a problem with the color despite the lack of itching or a rash. (
  • Albinism is not a single condition but a group of disorders and in some varieties the skin, eye and hair color are almost normal. (
  • Different disorders associated with skin pigmentation may have different symptoms. (
  • The researchers theorize that a shift from consuming vitamin D-rich marine animals to consuming pasture animals, or a reduction in exposure to ultraviolent rays, might have changed skin pigmentation over time. (
  • Pregnancy, Addison's disease, and sun exposure all can make your skin darker. (
  • Pregnancy and sun exposure can also make skin darker, while infections, burns, and blisters can make skin lighter. (
  • With chronic sun exposure, however, melanocytes become hyperactive and release too much melanin that manifests as unsightly age spots and dark patches on the skin. (
  • Whether the cause is genetic or from too much sun exposure, pigmentation and uneven skin tone need special attention. (
  • Surprisingly, 90% of what we perceive as aging is actually caused by factors that you can control, the main one being the amount of time your skin spends exposed to the sun. 2 Excessive sun exposure may be responsible for structural changes in the skin that will not be seen for years, and can also cause drastic changes to your skin's pigmentation. (
  • Melanocytes produce melanin, the pigment that gives your skin its color, so more exposure to the sun's radiation means more pigment in your skin. (
  • The good news is that you can manage pigmentation changes to your skin by limiting your exposure to the sun and avoiding unnecessary trauma to your skin. (
  • Researchers have identified a protein that plays an important, early role in the increase of protective skin pigmentation after exposure to ultraviolet (UV) radiation. (
  • The most novel part of this study was the fact that we identified a new transcription factor that may be the earliest responder to stimulation of pigmentation such as seen in the tanning reaction following UV exposure," said Vincent Hearing, Ph.D., chief of the NCI's Center for Cancer Research's (CCR) Pigment Cell Biology Section and senior author of the study. (
  • It's these ageing dark spots of bother that is known as pigmentation, caused by sun exposure and specifically the UVA rays which penetrate deep into your skin and cause ageing. (
  • Special cells in the skin make melanin, but when these cells become damaged or unhealthy (usually by sun exposure), it affects melanin production. (
  • Production of melanin is dependent on UV or sun exposure, and is a natural protective mechanism of the skin. (
  • Changes in skin color appearance were documented by photography, colorimetry, and DRS. In the UV exposure experiment all reactions were dose dependent. (
  • This is being done as part of a study assessing the contribution of skin pigmentation, sun exposure, and diet to the level of vitamin D in a person's body. (
  • Divergent natural selection caused by differences in solar exposure has resulted in distinctive variations in skin color between human populations. (
  • Evolution is not officially linked to skin pigmentation but it is generally accepted that genetics and sunlight exposure are factors that affect the color. (
  • Finally, Montagna and Carlisle 2 also observed the stratum lucidum, the layer beneath the stratum corneum composed of 3-5 layers of keratinocytes, and found the stratum lucidum in black skin was unaltered by UV exposure, whereas white skin was usually distorted by UV exposure. (
  • Jablonski said that there are ways to increase vitamin D without increasing the risk of skin cancer through exposure to the sun. (
  • However, following the loss of body hair - which helped the early humans stay active without overheating - permanent dark pigmentation became a crucial evolutionary tool to manage exposure to ultraviolet rays, according to Jablonski. (
  • Your practitioner will also evaluate whether external factors, such as medications, chemical exposure, or other environmental influences, could have contributed to the increased deposition of pigment in the skin. (
  • The degree of pigmentation in the skin changes according to the amount of ultraviolet light exposure, so that freckles usually darken in the summer and lighten in the winter. (
  • There are several ways of treating skin pigmentation but the first step that anyone should take in treating pigmentation is preventing more exposure of the skin to the sun's ultraviolet radiation. (
  • This kind of pigmentation will appear on parts of the skin where there is plenty of exposure to the sun, but you do not have to worry about these spots being cancerous. (
  • Minimizing intense sun exposure, wearing sun protective clothing and wide-brimmed hats, along with applying a broad-spectrum sunscreen with an SPF 30 is a must for treating Asian skin for this reason. (
  • Repeated sun exposure causes this type of pigmentation - the older we get, the more the sun damage from our youth rises to the surface. (
  • The evolution of differing skin colors arose as our bodies' adaptation to varied climates and levels of UV exposure, explains Cheng, Professor and Chief of the Division of Experimental Pathology at Penn State Hershey College of Medicine and Co-Director of Penn State IBIOS Bioinformatics and Genomics graduate program. (
  • Symptoms like itching or redness may occur with sunlight exposure but usually there are no other symptoms beyond the lack of pigmentation. (
  • It's important to limit sun exposure to stop existing pigmentation from darkening and prevent new spots from forming. (
  • But what causes such a change is mostly strong sun exposure on the skin. (
  • But if you expose your skin to sun rays for a long time, the exposure might damage your skin cells and cause the melanin to under produce or overproduce itself causing skin pigmentation. (
  • Thus, it is important to protect your skin from sun exposure by using sunscreen, wearing hats when outdoors and avoid sun exposure between 10 AM-4 PM. (
  • A beautiful skin contributes greatly to our overall appearance and should be carefully protected from the effects of sun exposure. (
  • The mode of treatment used will be dependent on the type of pigmentation, patient preference, and patient risk tolerance. (

  • This type of pigmentation occurs due to injury or inflammation. (
  • This type of pigmentation is often caused by genetics. (
  • Most commercial skin lighteners contain ingredients that only target one stage of the process, producing some improvements in skin discoloration. (
  • Potential treatments for this skin discoloration include topical (applied on the skin) bleaching agents, such as hydroquinone, and laser treatments. (
  • It's worth bearing in mind that discoloration is actually present in dead surface cells, so it is imperative to exfoliate regularly to slough off the build-up, which will help minimize hyper-pigmentation and lighten up the appearance. (

  • After showing that melanocytes in normal human skin express SOX9 under normal conditions, the investigators exposed normal human melanocytes to UV radiation, and compared the levels of SOX9 between radiated and non-radiated cells. (
  • The researchers exposed normal human melanocytes and reconstructed skin samples to a chemical called forskolin, which stimulates the cAMP pathway. (
  • Excessive skin pigmentation is a result of abnormal production and deposition of melanin by the melanocytes. (
  • The number of melanocytes present in our skin will determine our skin colour. (
  • Our hair, skin and eyes are colored by a pigment called melanin, which is produced by pigment cells called melanocytes. (
  • 4 Regarding variations in human skin color, Szabo noted the density of pigment producing melanocytes in the skin, approximately 1,000/mm 2 , was not found to vary with ethnicity. (

  • It is produced by specialized pigment cells, known as melanocytes, in the deepest layer of the epidermis (outer skin). (
  • More active melanocytes produce more melanin which is responsible for darker skin colors and less active melanocytes are responsible for lighter skin shades. (
  • It is likewise thought to be brought on by the immune system assaulting and damaging the melanocytes of the skin. (

  • This is darkening of the skin caused by inflammation (e.g acne, eczema, psoriasis) or trauma to the skin (e.g burns, aesthetic procedures such as laser, chemical peels). (
  • Skin diseases that cause inflammation often also cause changes in skin color. (
  • By its very nature, Asian skin has an increased amount of melanin (the pigment in skin), and the cells that make melanin tend to be more sensitive to any type of inflammation or injury. (
  • Nevertheless a skin rash is usually a result of inflammation in the skin. (

  • Skin colour is one of the most visible and variable traits among humans and scientists have always been curious about how this variation evolved. (
  • But until now, few genes have been shown to contribute to normal variation in skin color, and these had primarily been discovered through studies of European populations. (
  • It is unclear whether selection has operated on all the genetic variation associated with skin pigmentation as opposed to just a small number of large-effect variants. (
  • This study shows that the response to selection for light skin pigmentation in West Eurasia was driven by a relatively small proportion of the variants that are associated with present-day phenotypic variation. (

  • Most of us think of the form known as oculucutaneous albinism where skin, eye and hair color is drastically affected. (
  • People with this type of albinism are generally sensitive to the sun and have an increased risk of developing skin cancer. (
  • White fur doesn't necessarily signify total albinism: There are several gene combinations that result in partial, lightly colored coats and skin patterns. (
  • As might be expected, these abnormal skin colorations will appear at birth or just a few weeks after birth. (
  • A condition which is characterized by an abnormal excess of skin pigmentation. (
  • Individuals who carry two copies of the lighter pigmentation gene are 14 percent lighter-skinned than the population average, the researchers said. (
  • Even though people with skin of color have less moles and experience less premature aging from the sun than lighter-skinned individuals, in some ways their darker pigmentation makes their skin more vulnerable to other skin problems,' said Dr. Breadon. (
  • UV radiation from the sun or other sources, such as tanning parlors, can cause many types of damage to the skin and has been associated with a process that leads to many types of skin cancers. (
  • Individuals with lighter skin incur greater damage from UV and thus have significantly higher risk for skin cancer. (
  • On the flipside, if you look deeper, you'll often find you are left with some not-so-pleasant reminders of the sun - skin pigmentation and sun damage some of them. (
  • When it comes to clearing up pigmentation and damage caused by the Sun, La Roche Posay excels in this areas due to it's gentle yet effective formulations. (
  • This allows the laser to selectively disrupt the pigment with minimal or no damage to surrounding skin. (
  • In fact, any brown patches that you see on your skin now are likely the result of sun damage from 10 years ago. (
  • Individuals with SHEP2 often have partial loss-of-function mutations of MC1R, which encodes melanocortin 1 receptor, and are characterised by fair skin, blonde or red hair, poor tanning and increased risk of skin cancer due to increased susceptibility to UV-light-induced skin damage. (
  • For more advanced results, we offer a range of skin treatments at Caci to reduce pigmentation and sun damage. (
  • Injury inflicts such a damage hence causing skin pigmentation. (
  • The darker the skin color, the more protective effect there is against solar radiation damage. (
  • Although AMO skin is more protected against the sun, it is not exempt from the ravages of sun damage, which is the primary cause of skin cancers. (
