Melanin is the pigment that gives skin its color; it is produced by skin cells called melanocytes. Variations in genes that are part of the immune system or part of melanocytes have both been associated with vitiligo. [2] It is also thought to be caused by the immune system attacking and destroying the melanocytes of the skin. [18]
Nevus depigmentosus is a loss of pigment in the skin which can be easily differentiated from vitiligo. Although age factor has not much involvement in the nevus depigmentosus but in about 19% of the cases these are noted at birth. Their size may however grow in proportion to growth of the body.
The pigment loss can be partial (injury to the skin) or complete (caused by vitiligo). It can be temporary (from tinea versicolor) or permanent (from albinism). [1] Most commonly, depigmentation of the skin is linked to people born with vitiligo, which produces differing areas of light and dark skin. Monobenzone also causes skin depigmentation.
Your doctor may suggest taking a low dose of melatonin because it inhibits tyrosinase (an enzyme in our skin that helps produce melanin), reducing pigment production, says Dr. Charles. Dr.
Genetics, sun exposure, and some drugs are the three main factors that contribute to skin pigmentation. [4] The most frequent cause of low melanin concentration (hypopigmentation) is prior skin trauma, which includes skin lesions including blisters, burns, infections, exposure to chemicals, and other wounds. The skin will appear paler than the ...

Postinflammatory hypopigmentation is a highly prevalent pigmentary disease. It can happen to any type of skin. Nonetheless, individuals with darker skin seem to have it more frequently and visibly, perhaps due to the color contrast with their natural skin. The incidence of postinflammatory hypopigmentation is the same for both sexes. [2]
