The so-called “mask of pregnancy” is a form of hyperpigmentation associated with hormonal activity and ultraviolet light exposure. It may also occur among women who take oral contraceptives. Melasma appears as symmetrical light to dark brown patches on the face, particularly the cheeks. Epidermal melasma tends to fade well on its own; dermal melasma is more stubborn and long lasting. In either case, the pigmented skin can be reduced by sun avoidance and good skin care.
