Melasma is a skin condition in which brown patches, also known as hyperpigmentation, form on the face. Melasma is most commonly found on the cheeks, forehead, bridge of the nose, and the area above the upper lip. Although men and women may develop melasma, it is most common in women; this may be attributed to hormonal influences, such as pregnancy, oral contraceptive use, or hormone replacement therapy.
Since melasma may be worsened by sun exposure, sunscreen plays an important role in the prevention and treatment of melasma. Melasma may also be treated with a combination of prescription topical depigmenting agents, such as hydroquinone, as well as chemical peels and laser treatments.
