UV rays pass through the epidermis and stimulate the cells that produce melanin (melanocytes). Some melanocytes are affected and begin to secrete large amounts of melanin continuously. Excessive melanin is not distributed evenly over the surface of the skin. This causes it to accumulate in certain spots and form unsightly stains.

Spots on the skin are usually related to skin aging and/or sun exposure.

They can also arise due to hormonal factors or contraceptive pills/hormone replacement as in melasma, after skin injuries such as acne/burns/irritations or genetic predisposition.

Pigmented skin requires gradual treatment. The Dr Mariana Morais Skincare routine uses ingredients that gradually fade dark spots, while calming irritation and increasing radiance.

(Although most dark spots on the skin are harmless, it is important to be aware of more serious medical conditions such as carcinomas. Call your doctor if you notice any changes in color, size or shape.)
