Exposure of farmers to phosmet, a swine insecticide. (1/693)

OBJECTIVES: The goal of this study was to measure dermal and inhalation exposures to phosmet during application to animals and to identify what determinants of exposure influence the exposure levels. METHODS: Ten farmers were monitored using dermal patches, gloves, and air sampling media during normal activities of applying phosmet to pigs for insect control. Exposures were measured on the clothing (outer), under the clothing (inner), on the hands, and in the air. Possible exposure determinants were identified, and a questionnaire on work practices was administered. RESULTS: The geometric mean of the outer exposure measurements was 79 microg/h, whereas the geometric mean of the inner exposure measurements was 6 microg/h. The geometric mean for hand exposure was 534 microg/h, and the mean air concentration was 0.2 microg/m3. Glove use was associated with the hand and total dermal exposure levels, but no other determinant was associated with any of the exposure measures. The average penetration through the clothing was 54%, which dropped to 8% when the farmers wearing short sleeves were excluded. The farmers reported an average of 40 hours a year performing insecticide-related tasks. CONCLUSIONS: Farmers who applied phosmet to animals had measurable exposures, but the levels were lower than what has been seen in other pesticide applications. Inhalation exposures were insignificant when compared with dermal exposures, which came primarily from the hands. Clothing, particularly gloves, provided substantial protection from exposures. No other exposure determinant was identified.  (+info)

In vivo skin decontamination of methylene bisphenyl isocyanate (MDI): soap and water ineffective compared to polypropylene glycol, polyglycol-based cleanser, and corn oil. (2/693)

In the home and workplace, decontamination of a chemical from skin is traditionally done with a soap-and-water wash, although some workplaces may have emergency showers. It has been assumed that these procedures are effective, yet workplace illness and even death occur from chemical contamination. Water, or soap and water, may not be the most effective means of skin decontamination, particularly for fat-soluble materials. This study was undertaken to help determine whether there are more effective means of removing methylene bisphenyl isocyanate (MDI), a potent contact sensitizer, from the skin. MDI is an industrial chemical for which skin decontamination, using traditional soap and water and nontraditional polypropylene glycol, a polyglycol-based cleanser (PG-C), and corn oil were all tried in vivo on the rhesus monkey, over 8 h. Water, alone and with soap (5% and 50% soap), were partially effective in the first h after exposure, removing 51-69% of the applied dose. However, decontamination fell to 40-52% at 4 h and 29-46% by 8 h. Thus, the majority of MDI was not removed by the traditional soap-and-water wash; skin tape stripping after washing confirmed that MDI was still on the skin. In contrast, polypropylene glycol, PG-C, and corn oil all removed 68-86% of the MDI in the first h, 74-79% at 4 h, and 72-86% at 8 h. Statistically, polypropylene glycol, PG-C, and corn oil were all better (p < 0.05) than soap and water at 4 and 8 h after dose application. These results indicate that a traditional soap-and-water wash and the emergency water shower are relatively ineffective at removing MDI from the skin. More effective decontamination procedures, as shown here, are available. These procedures are consistent with the partial miscibility of MDI in corn oil and polyglycols.  (+info)

Dermal transfer of chlorpyrifos residues from residential surfaces: comparison of hand press, hand drag, wipe, and polyurethane foam roller measurements after broadcast and aerosol pesticide applications. (3/693)

Indoor residential pesticide applications present the potential for human exposures, particularly for small children. Personal contact with target and nontarget surfaces can result in transfer of pesticides to the skin, but the magnitude of such transfer is uncertain. This research compared surface sampling techniques [wipe and polyurethane foam (PUF) roller] with the removal ability of human skin following broadcast and total aerosol release applications of Dursban (Dow Elanco, Midland, MI), a residential formulation containing the insecticide chlorpyrifos. Hands were washed immediately after surface contact, following a protocol that included a laboratory-generated adjustment factor to account for incomplete removal of chlorpyrifos from skin. Chlorpyrifos transfer was similar for hand press and hand drag techniques, averaging approximately 1-6 ng/cm2 of carpet contacted. These amounts represented < 1% of the amount of chlorpyrifos deposited on the surfaces 3.5 hr earlier. Chlorpyrifos transfer from carpet to skin was 23-24 times lower than for wipe sampling and 33-36 times lower than for PUF roller sampling (p = 0.0007 and p = 0.0006 for broadcast and aerosol applications, respectively). Hand press sampling removed approximately 4.5 times less chlorpyrifos from nontarget furniture surfaces (12 ng/cm2) than did wipe sampling (56 ng/cm2; p = 0.009). Chlorpyrifos residues on carpet were substantially higher after broadcast applications than after aerosol applications, but residues on such nontarget surfaces as furniture were substantially higher for the aerosol application. This study indicates that human skin removes substantially less residue from carpets and furniture than either conventional wipe or PUF roller sampling methods following residential pest control applications of chlorpyrifos. Although this paper focuses on quantifying residue transfer from surface to skin using different surface sampling techniques, no attempt is made to quantify the amount of chlorpyrifos residue that is subsequently absorbed.  (+info)

Oral and dermal absorption of chlorpyrifos: a human volunteer study. (4/693)

OBJECTIVES: To determine the kinetics of elimination of urinary dialkylphosphate metabolites after oral and dermally applied doses of the organophosphate pesticide chlorpyrifos to human volunteers and to determine whether these doses affected plasma and erythrocyte cholinesterase activity. METHOD: Five volunteers ingested 1 mg (2852 nmol) of chlorpyrifos. Blood samples were taken over 24 hours and total void volumes of urine were collected over 100 hours. Four weeks later 28.59 mg (81567 nmol) of chlorpyrifos was administered dermally to each volunteer for 8 hours. Unabsorbed chlorpyrifos was washed from the skin and retained for subsequent measurement. The same blood and urine sampling regime was followed as for the oral administration. Plasma and erythrocyte cholinesterase concentrations were determined for each blood sample. The concentration of two urinary metabolites of chlorpyrifos--diethylphosphate and diethyl-thiophosphate--was determined for each urine sample. RESULTS: The apparent elimination half life of urinary dialkylphosphates after the oral dose was 15.5 hours and after the dermal dose it was 30 hours. Most of the oral dose (mean (range) 93% (55-115%)) and 1% of the applied dermal dose was recovered as urinary metabolites. About half (53%) of the dermal dose was recovered from the skin surface. The absorption rate through the skin, as measured by urinary metabolites was 456 ng/cm2/h. Blood plasma and erythrocyte cholinesterase activity did not fall significantly during either dosing regime. CONCLUSION: An oral dose of chlorpyrifos was readily absorbed through the skin and almost all of the dose was recovered as urinary dialkylphosphate metabolites. Excretion was delayed compared with the oral dose. Only a small proportion of the applied dose was recovered during the course of the experiment. The best time to collect urine samples for biological monitoring after dermal exposure is before the shift the next day. The amounts of chlorpyrifos used did not depress acetyl cholinesterase activity but could be readily detected as urinary dialkylphosphate metabolites indicating that the urinary assay is a more sensitive indicator of exposure.  (+info)

Estimation of the dermal absorption of m-xylene vapor in humans using breath sampling and physiologically based pharmacokinetic analysis. (5/693)

A physiologically-based pharmacokinetic model, containing a skin compartment, was derived and used to simulate experimentally determined exposure to m-xylene, using human volunteers exposed under controlled conditions. Biological monitoring was conducted by sampling, in exhaled alveolar air and blood, m-xylene and urinary methyl hippuric acid concentrations. The dermal absorption of m-xylene vapor was successfully and conveniently studied using a breath sampling technique, and the contribution to m-xylene body burden from the dermal route of exposure was estimated to be 1.8%. The model was used to investigate the protection afforded by an air-fed, half-face mask. By iteratively changing the dermal exposure concentration, it was possible to predict the ambient concentration that was required to deliver the observed urinary excretion of methylhippuric acid, during and following inhalation exposure to 50 ppm m-xylene vapor. This latter extrapolation demonstrates how physiologically-based pharmacokinetic modeling can be applied in a practical and occupationally relevant way, and permitted a further step not possible with biological monitoring alone. The ability of the model to extrapolate an ambient exposure concentration was dependent upon human metabolism data, thereby demonstrating the mechanistic toxicological basis of model output. The methyl hydroxylation of m-xylene is catalyzed by the hepatic mixed function oxidase enzyme, cytochrome P450 2E1 and is active in the occupationally relevant, (<100 ppm) exposure range of m-xylene. The use of a scaled-up in vitro maximum rate of metabolism (Vmaxc) in the model also demonstrates the increasingly valuable potential utility of biokinetic data determined using alternative, non-animal methods in human chemical-risk assessment.  (+info)

Predicting vehicle effects on the dermal absorption of halogenated methanes using physiologically based modeling. (6/693)

Occupational and environmental settings present opportunities for humans to come into contact with a variety of chemicals via the dermal route. The chemicals contacting the skin are likely to be diluted with a vehicle or present as a component of a mixture. In order to support risk assessment activities, we evaluated the vehicle effects on dermal penetration of two halogenated hydrocarbons, dibromomethane (DBM) and bromochloromethane (BCM). In vivo exposures to 15 combinations of of these in water, mineral oil, and corn oil vehicles were conducted, and blood was sampled for dibromomethane and bromochloromethane during the exposure at 0.5, 1, 2, 4, 8, 12, and 24 h. A physiologically based pharmacokinetic (PBPK) model was used to estimate the total amounts of dibromomethane or bromochloromethane that were absorbed during the exposure, and the dermal permeability coefficients were determined. While the permeability coefficients for dibromomethane and bromochloromethane were approximately 73- and 40-fold higher, respectively, in the water vehicle than in the corn oil, the permeability coefficient, when normalized for the skin:vehicle matrix partition coefficient, varied by less than a factor of 2. The permeability in an aqueous vehicle was then successfully used to predict the permeability coefficient for dibromomethane in a nonpolar vehicle, peanut oil.  (+info)

In vitro test of nicotine's permeability through human skin. Risk evaluation and safety aspects. (7/693)

Permeability tests with Franz' diffusion cells and an in vitro test model were made to evaluate the importance of dermal absorption of nicotine as a pathway for intoxication. Studies were carried out to ensure that safety procedures, when spilling nicotine on skin, are sufficient to prevent poisoning. Pure nicotine and nicotine in various concentrations in water or ethanol were applied on human skin or gloves in Franz' cells. Washing was simulated by removing nicotine from skin after 3 or 5 min. Permeation rate (flux) and lag time were calculated and estimated for human skin. Different glove materials were tested for their nicotine breakthrough time. Flux depended on concentration in a non-linear way when nicotine-water solutions were tested. Highest flux was found in 50% w/w nicotine dissolved in water. Solutions with low concentration of nicotine (1% w/w) dissolved in water had a similar permeation rate to 100% nicotine. Flux was found to be low when using ethanol as a vehicle; flux was also pH-dependent. The nicotine-water solution containing acetic acid had the lowest flux. The tests where nicotine was washed away revealed that skin served as a possible nicotine depot, because nicotine concentration in the receptor compartment continued to increase after removing the nicotine from the surface. The length of contact time affected the amount of substance passing the skin, resulting in great difference between 3 and 5 min contact time, 5 min giving higher nicotine concentration and 3 min lower. This emphasizes the importance of washing away nicotine spilled on skin rapidly. Two glove types were tested and they were found to be appropriate in their use with nicotine if changed regularly.  (+info)

Dermal application of JP-8 jet fuel induces immune suppression. (8/693)

Chronic exposure to JP-8 jet fuel induces lung toxicity, adverse neurological effects and some liver and kidney dysfunction. In addition, inhalation of JP-8 induces immune suppression. Besides the lung, the other major route of JP-8 exposure is via the skin. In this study we tested the hypothesis that dermal exposure to JP-8 is immune suppressive. JP-8 was applied to the skin of adult female C3H/HeN mice and various immune parameters were examined. Dermal exposure to JP-8, either multiple small exposures (50 microl for 5 days) or a single large dose (250-300 microl) resulted in immune suppression. The induction of contact hypersensitivity was impaired in a dose-dependent manner regardless of whether the contact allergen was applied directly to the JP-8-treated skin or at a distant un-treated site. In addition, the generation of a classic delayed-type hypersensitivity reaction to a bacterial antigen (Borellia burgdorferi) injected into the subcutaneous space was suppressed by dermal application of JP-8 at a distant site. The ability of splenic T lymphocytes from JP-8-treated mice to proliferate in response to plate-bound monoclonal anti-CD3 was also significantly suppressed. Interleukin-10, a cytokine with potent immune suppressive activity, was found in the serum of JP-8-treated mice, suggesting that the mechanism of systemic immune suppression may involve the upregulation of cytokine release by JP-8. These findings confirm the immunosuppressive effects of JP-8 and demonstrate that dermal exposure to JP-8 is immunotoxic.  (+info)

The permeation of drugs through skin can be enhanced by various methods including physical methods such as iontophoresis, phonophoresis , eletroporation and by chemical penetration enhancers etc. The Transdermal route has been recognized as one of the highly potential routes of systemic drug delivery. However, the major limitation of this route is the difficulty of permeation of drug through the skin. Studies have been carried out to find safe and suitable permeation enhancers to promote the percutaneous absorption of a number of drugs. The present review highlights various categories of penetration enhancers; the involved mechanism leading to a judicious selection of suitable penetration enhancers for improving the Transdermal permeation of poorly absorbed drugs.

Magnesium is an important micronutrient essential for various biological processes and its deficiency has been linked to several inflammatory disorders in humans. Topical magnesium delivery is one of the oldest forms of therapy for skin diseases, for example Dead Sea therapy and Epsom salt baths. Some anecdotal evidence and a few published reports have attributed amelioration of inflammatory skin conditions to the topical application of magnesium. On the other hand, transport of magnesium ions across the protective barrier of skin, the stratum corneum, is contentious. Our primary aim in this study was to estimate the extent of magnesium ion permeation through human skin and the role of hair follicles in facilitating the permeation. Upon topical application of magnesium solution, we found that magnesium penetrates through human stratum corneum and it depends on concentration and time of exposure. We also found that hair follicles make a significant contribution to magnesium penetration.. ...
This thesis seeks to resolve difficulties in the development of a parenteral needle-free drug delivery system. Analysis of the penetration performance of Glide Pharmas Solid Dose Injector in two clinical trials on man has shown that skin, and likely its inherent variation, was the cause of incomplete deliveries. As indicated by the literature and issues with previous needle-free technologies, a more complete understanding of skin penetration is required before such systems are capable of ensuring delivery across a patient population. Exploratory skin experiments led to the justification, design and build of a novel skin penetration test rig capable of simulating the delivery of a solid dose implant. This test rig, the Penetrometer, required significant software development to both stabilise and validate its performance before use on the in vivo porcine model, an established non-clinical model for drug delivery through human skin. Two non-clinical studies have been performed using the ...

Under many aqueous conditions, metal oxide nanoparticles attract other nanoparticles and grow into fractal aggregates as the result of a balance between electrostatic and Van Der Waals interactions. Although particle coagulation has been studied for over a century, the effect of light on the state of aggregation is not well understood. Since nanoparticle mobility and toxicity have been shown to be a function of aggregate size, and generally increase as size decreases, photo-induced disaggregation may have significant effects. We show that ambient light and other light sources can partially disaggregate nanoparticles from the aggregates and increase the dermal transport of nanoparticles, such that small nanoparticle clusters can readily diffuse into and through the dermal profile, likely via the interstitial spaces. The discovery of photoinduced disaggregation presents a new phenomenon that has not been previously reported or considered in coagulation theory or transdermal toxicological paradigms. Our

Toxicokinetic studies performed on enzymes are very limited, but toxicokinetic information can be derived from the structure of enzymes combined with knowledge available for proteins in general since enzymes are proteins with catalytic activity. Absorption Skin: The physico-chemical properties of a compound are decisive for the potential percutaneous penetration, in particular factors like ionization, molecular size and lipophilicity. In general, non-ionized molecules easily penetrate the skin, with small molecules penetrating more easily than large molecules. Lipophilicity also facilitates penetration. Investigations of percutaneous absorption of peptides, proteins and other molecules of large size revealed that percutaneous absorption of proteins is extremely low and of no toxicological relevance [1;2]. Gastrointestinal tract: Proteins are digested into amino acids by pancreatic proteolytic enzymes, digestive enzymes and gastric juices in the lumen of the gastrointestinal tract [3]. As enzymes ...

The aqueous thermal boundary layer near to the ocean surface, or skin layer, has thickness O(1 mm) and plays an important role in controlling the exchange of heat between the atmosphere and the ocean. Theoretical arguments and experimental measurements are used to investigate the dynamics of the skin layer under the influence of an upwelling flow, which is imposed in addition to free convection below a cooled water surface. Previous theories of straining flow in the skin layer are considered and a simple extension of a surface straining model is posed to describe the combination of turbulence and an upwelling flow. An additional theory is also proposed, conceptually based on the buoyancy-driven instability of a laminar straining flow cooled from above. In all three theories considered two distinct regimes are observed for different values of the Péclet number, which characterizes the ratio of advection to diffusion within the skin layer. For large Péclet numbers, the upwelling flow dominates ...

Cadaver skin is undoubtedly the best alternative to autograft, but ready supply is unreliable, and legislative and cultural restrictions have significantly influenced availability. This review summarises the indications for cadaver skin in burn surgery and complex wound care. The South African Burn Society prioritises the establishment of a deceased donor skin bank in South Africa, whose mandate it would be to procure and store allograft for distribution to burns units when required.
A skin-mimicking artificial membrane consisting of a silicone membrane as a model stratum corneum and laminated dialysis membranes as a model of viable skin was prepared to imitate the layered structure of skin. The permeability of flurbiprofen (FP) through the laminated membranes agreed with that calculated, suggesting that the interfacial resistance between each membrane was negligible. When the FP concentration in the laminated membranes was determined by microdialysis, the observed concentration was similar to that calculated according to Ficks law of diffusion. When bovine serum albumin (BSA) solution was placed between the dialysis membranes to mimic the protein leaching in skin, the FP permeation profiles through the membranes showed a long lag-time without dependence on the depth of the region of the inserted BSA from the surface. However, the FP concentration-time profiles in a region between the membranes showed dependence on the region of the inserted BSA. Since the FP concentration ...
Abstract:. Objective: The aim of present study was to prepare and evaluate the transdermal films (TFs) of Nifedipine (NFDP). Methods: The TFs were prepared by solvent evaporation technique and twelve formulations of NFDPTFs were prepared by taking HPMC E15 and Eudragit L100 in different ratios. Polyethylene glycol (15%) and Dimethyl sulfoxide (DMSO) were incorporated as plasticizer and permeation enhancer respectively. DMSO was incorporated in the formulations F7-F12 but it was absent in F1-F6. Results: The prepared TFs were evaluated for weight variation, thickness, folding endurance, drug content, moisture absorption, moisture content determination, mechanical properties and ex-vivo permeation. Mechanical properties revealed that the formulations F4 and F10 were found to be strong enough but not brittle. Hence, the formulations F4 and F10 were selected for ex-vivo studies. The formulations F4 and F10 showed maximum drug permeation within 24 h and formulation with permeation enhancer showed ...
2011 and Garland et al., 2011). In dermatomed skin, it was found that holes could find more be detected in porcine skin at 0.05 N/needle and 0.1 N/needle. This confirmed that the SC barrier would be penetrated at each of these insertion forces. As the SC barrier is the principal barrier of the skin, once this barrier is breached, then transdermal transport is solely controlled by the properties of the drug delivery device employed, rather than the SC, as the viable epidermis. does not constitute a meaningful barrier to drug penetration ( Tanner and Marks, 2008). Once it was confirmed that rat blood did not interfere with the plaque assay, a calibration plot was carried out to assess what concentration of phages could be detected using the assay. With a starting concentration of 3 × 108 PFU/ml,. it was found ON-01910 cost that the minimum limit of detection for the assay was 30 PFU/ml. The reduced concentration detected from the full thickness skin experiment (approximately 3 log) compared to ...

Natural oils are commonly used in topical pharmaceutical formulations as emulsifiers, stabilizers or solubility enhancers. They are presented as safe and inert components, mainly used for formulation purposes. It is confirmed that natural oils can affect the skin penetration of various substances. Fatty acids are mainly responsible for this effect. Current understanding lacks reliable scientific data on penetration of natural oils into the skin and their skin penetration enhancement potential. In the current study, fatty acid content analysis was used to determine the principal fatty acids in soybean, olive, avocado, sea-buckthorn pulp, raspberry seed and coconut oils. Time of flight secondary ion mass spectrometry bioimaging was used to determine the distribution of these fatty acids in human skin ex vivo after application of the oils. Skin penetration enhancement ratios were determined for a perspective antioxidant compound dihydroquercetin. The results demonstrated skin penetration of fatty acids
Transdermal drug delivery systems (TDS) are pharmaceutical devices that are designed to deliver specific drugs to the human body by diffusion through skin. The TDS effectiveness suffers from crystallization in the patch when they are kept in storage for more than two years. It has been reported that there are two types of crystals in the patch: needle and aggregate, and growth of drug crystals in TDS generally occurs only in the middle third of the polymer layer. In our study, fluorescence microscopy, EDS (SEM) and Raman microspectroscopy were used to further characterize the crystals. The results show that the needle crystals most probably contain estradiol and acrylic resin conjugate. The FTIR spectrum of the model sample proved the occurrence of a reaction between estradiol and acrylic resin. Crystal growth in an unstressed matrix of a dissolved crystallizable drug component was simulated using a kinetic Monte Carlo model. Simulation using Potts model with proper boundary condition gives the ...
Flector plaster is a new transdermal delivery system medicated with diclofenac hydroxyethylpyrrolidine salt, an NSAID which seems to possess suitable physiochemical properties for easy release by the plaster matrix for percutaneous absorption. The paper deals with local tolerability and pharmacokinetic (percutaneous absorption) studies carried out both on animals and on volunteers. The results obtained in the safety studies demonstrate the absence of local skin reactions and of sensitization phenomena. The kinetic evidence, obtained at the steady-state, reveals a profile typical of a sustained-release formulation, able to maintain constant plasma levels of the drug up to the next application (12 h). The amount of drug bioavailable for targeting the sites of action is effectively lower than via the oral route, however the estimated absorbed dose of 5-10 mg per application appears to be adequate for the foreseen therapeutic use, taking into account the great advantage in having no undesirable side effects

Polymeric networks that retain and absorb substantial amount of water or biological fluids and resemble as a biological tissue are defined as hydrogels. On the other hand, liposomes, transfersomes and niosomes are lipid carriers, which represent one of the major research and development focus areas of the pharmaceutical industry. They have great potential as lipid vehicles that are able to enhance permeation of drugs across the intact skin and can act as local depot for the drug to sustain and control its delivery. Lipid carrier and hydrogel combinations offer transdermal drug delivery of great potential to enhance systemic effects of both hydrophilic and lipophilic drugs. Also, lipid carriers can target drugs to skin appendages and improve transdermal delivery. Lipid carrier proform systems in the form of gelly liquid crystals can also be used transdermally for better drug absorption enhancement. This review highlights the potential of hydrogels and emulgels with or without lipid nanocarriers for
The present investigation aimed at formulation, and performance evaluation of vesicular drug carrier system proniosomal gel for transdermal delivery of antifungal agent, griseofulvin. Proniosomal gel (PNG) formulations of griseofulvin were prepared, and characterized for vesicles shape, size, entrapment efficiency, and drug permeation across pig ear skin. The effects of different non-ionic surfactants on transdermal permeability profile were assessed. The optimized PNG formulation showed enhanced in vitro skin permeation flux of 3.682±0.186 µg/cm2/hr as compared to 0.028 ± 0.02 µg/cm2/hr for plain drug solution in water. Results indicated that the optimized PNG formulation of griseofulvin had better skin permeation potential than plain drug solution in water.

Skin making lighter creams are especially developed to make lighter dark skin layer color. They function by reducing the level of melanin, which is actually the pigment made through your skin tissues and also handles the different colors of your skin layer. These creams may either be utilized by themselves or even as aspect of a skin layer lightening system. They are actually accessible in both natural as well as pharmaceutical types.. The best usual skin layer lightening items are actually those that could be located such as gels, creams, sprays and lotion. They all work by hindering melanin creation, which can bring about age spots, yellowing and darker locations of your skin. These making lighter items are actually utilized mostly as location treatments or for a lighter skin tone on the surface.. Some making lighter creams might trigger unpleasant effects like acne, photosensitivity, fast heart beat and skin layer thinning. In reality, there specify medications such as bleomycin and also ...
Amber Self MicroDermAbrasion 2 oz If exfoliation isnt a regular part of your skin care regimen, it should be. Your skins dead, hardened outer layer not only worsens the appearance of wrinkles, age spots, scars and blemishes-it also gradually destroys skin health, clogging pores and preventing the release of natural oils that normally help preserve natural softness and luster as you age. Thats why microdermabrasion is one of todays most popular nonsurgical exfoliation procedures. Under the supervision of a certified dermatologist, a spray of microfine crystals continuously removed by vacuum scours away dead skin cells and restores your skins youthful glow. Unfortunately, the outlandish cost for medically safe results causes microdermabrasion to be impractical for budget-conscious individuals. And if youre pregnant or breastfeeding, or suffer from a variety of health conditions including acne, rosacea, eczema, psoriasis or diabetes, microdermabrasion poses significant risks. Even healthy

Just like the skin care gadgets, I am always on the hunt for great microdermabrasion-type of products. I have a feeling if I actually went and got a microdermabrasion treatment at the dermatologist, I would be in for a much different treatment, but so far I am good, and the home products suit me fine. What makes a good microdermabrasion cream, to me, are the texture and the density of the grains that abrade your face - I like them very fine and very plentiful. If there are too few and they are too big, I categorize it as more of a classic exfoliator - does that make sense? To me an exfoliator is more creamy and less grainy than a microdermabrasion cream.. ...
Despite several advantages, such as a large available surface area and relatively low enzymatic degradation, the huge barrier of the stratum corneum makes percutaneous/dermal absorption a challenge. The percutaneous/dermal absorption process describes the passage of compounds across the skin and can be divided into three steps: penetration, permeation and resorption. The three main permeation routes through the stratum corneum are: the intercellular pathway, the intracellular pathway and the follicular pathway. Several physicochemical parameters affect the skin absorption and promoters can be used to enhance the penetration of an ingredient. OECD test guideline no. 428 is a regulatory accepted alternative method to access the skin absorption of a cosmetic ingredient ...

If youre interested in rejuvenating your skin, you might be wondering about the differences between microdermabrasion and glycolic peels. Both treatments will resurface and exfoliate the skin by removing the superficial outer layer. However, microdermabrasion and glycolic peels involve a different means of attaining the desired results and are recommended for different skin types and conditions. What is microdermabrasion? This treatment involves spraying fine crystals onto the surface of the skin in order to remove the outermost dead skin cells. Microdermabrasion aims to improve superficial skin imperfections. This includes age spots, fine lines, mild acne scars, sun damage, and fine wrinkling around the eyes, mild acne scars, age spots or sun spots, enlarged or visible pores, and fine lines. Because microdermabrasion is a simple resurfacing of the top layer of the skin, it is not recommended for deep wrinkles, moderate to severe scars, or pigmentary problems. Microdermabrasion treatment offers ...
