Skin pigmentation is the result of the deposition of melanin. Melanin is produced when inflammation causes tyrosinase to bind with copper in a
reaction known as melanogenesis. The inflammatory trigger can be UV light, Hormones, or surface irritation.
Melasma is a hormonally induced hyperpigmentation that usually covers the forehead, cheeks and/or upper lip. The area of hyperpigmentation is usually large in size with uneven borders. Melasma can result from hormonal changes experienced in pregnancy, menopause, hormone replacement therapy and/or oral contraception pills.
Melasma can be treated with the use of
chemical peels,
microdermabrasion and daily skincare products that inhibit melanogenisis, increase cell turnover and protect from UV rays.
