Melasma - Definition, Causes and Treatment
Melasmaalso known as chloasma or the mask of pregnancy, is a tan or dark facial skin discoloration. Although it can affect anyone, melasma is particularly common in women, especially pregnant women and those who are taking oral contraceptives or hormone replacement therapy (HRT) medications.
Melasma appears as a blotchy, brownish pigmentation on the face that develops slowly and fades with time. Chloasma usually affects women but occasionally is seen in young men who use after-shave lotions, scented soaps, and other toiletries. The disorder is most common in sunny climates and in people of Latin or Asian origin.
Melasma produces irregular, patchy areas of dark color that are the same on both sides of the face. The pigmentation most often occurs in the center of the face and on the cheeks, forehead, upper lip, and nose. Sometimes people have the patches only on the sides of the face. Rarely, melasma appears on the forearms. Melasma is mainly associated with hormonal changes.
Melasma, may also be noticed in healthy, normal, non-pregnant women,where it is presumed to be due to some mild and harmless hormonal imbalance. It produces dark brown patches of pigmentation on sun-exposed areas, usually on the face.
