• Melanin
  • Melanin is an oxidized compound that determines an individual's pigmentation. (scarsandspots.com)
  • For example: acne, burns (including sunburn), waxing, harsh facial scrubs, insect bites, abrasions, poorly performed aesthetic procedures and even chemicals in certain products can cause inflammation and in some cases this inflammation causes the melanocytes (pigment-producing cells in the skin) to overproduce melanin.
