    Chloasma; Mask of pregnancy; Pregnancy mask


    Melasma doesn't cause any other symptoms besides skin discoloration but may be of great cosmetic concern.

    A uniform brown color is usually seen over the cheeks, forehead, nose, or upper lip. It is most often symmetrical (matching on both sides of the face).

    Signs and tests

    Your health care provider can usually diagnose melasma based upon the appearance of your skin. A closer examination using a Wood's lamp may help guide your treatment.
