Melasma
Melasma is a skin disease, dark spots mainly on the face. Women suffer more, especially pregnant. Only 10% of men suffer from melasma.
The pigmentation of the skin, due to the hyperproduction of melanin, is a defense mechanism to protect itself from free radicals produced by solar radiation. But there are cases in which this pigmentation becomes messy. There is an excess production and an irregular distribution of melanin that leads to the appearance of hyperpigmented spots
Dermatologists use a light, known as Wood’s light, which indicates the type of melasma. The epidermal type is brown in color; the dermal, bluish gray and the mixed one is of a grayish-brown color, a combination of the previous ones.
