Melanosomes, which are organelles containing melanin, must be transported and increased during hyperpigmentation and tanning, while they shrink during hypopigmentation. [4] Skin pigmentation is frequently caused by sun exposure. To protect itself against UV radiation from the sun, the body makes more melanin. As a result, the skin may become ...
Monobenzone also causes skin depigmentation. Increasingly, people who are not afflicted with vitiligo experiment with lower concentrations of monobenzone creams in the hope of lightening their skin tone evenly. An alternate method of lightening is to use the chemical mequinol over an extended period of time.

However, the degree of inflammation affects both the melanin and dermal papillary ring contents.

It is caused by melanocyte or melanin depletion, or a decrease in the amino acid tyrosine, which is used by melanocytes to make melanin. [2] Some common genetic causes include mutations in the tyrosinase gene or OCA2 gene. [3] [4] As melanin pigments tend to be in the skin, eye, and hair, these are the commonly affected areas in those with ...
