Hyper-Pigmentation happens when there is an overproduction or uneven production of melanin. Melanin is a pigment produced by the basal cells of the dermis called melanocytes. (See fig 1.2) These cells coexist with other cells called keratinocytes, which are the dead cells forming the stratum corneum or epidermis (top layer of the skin).

Many factors can cause over or uneven production of melanin. These include birth control pills, pregnancy, hormone replacement therapy, sun exposure, drugs containing phototoxic agents, abrasions or acne.

An effective solution against Hyper-Pigmentation is to

i. Regulate melanin production.
ii. Prevent UV damage by applying a Dermatologist approved sunblock.
iii. Introduce a skin renewal program that allows getting rid of damaged skin and introducing new skin cells to replace it.
