Hyperpigmentation occurs when damaged skin cells produce excess melanin, causing darker patches. Causes include adrenal disorders, genetics, hormone changes, skin injuries, certain medications, melasma, vitamin deficiencies, sun damage, and thyroid disorders.
What Is it?
Hyperpigmentation is a common condition that makes some areas of the skin darker than others. Too much or too little melanin creates spots or patches that look brown, black, gray, red or pink.
