PATHOLOGY

Detailed explanation-1: -Hyperpigmentation is a common, usually harmless condition in which patches of skin become darker in color than the normal surrounding skin. This darkening occurs when an excess of melanin, the brown pigment that produces normal skin color, forms deposits in the skin.

Detailed explanation-2: -Your skin gets its color from a pigment called melanin. Special cells in the skin make melanin. When these cells become damaged or unhealthy, it affects melanin production.

Detailed explanation-3: -Melanin pigments are produced in the epidermis by highly specialized cells, the melanocytes, neural crest-derived cells migrating as melanoblasts, during embryogenesis, into the epidermis and hair follicles via the mesenchyme.

Detailed explanation-4: -Melanin is a natural pigment that gives your skin its color. It’s produced in cells called melanocytes.
