Melasma is a common skin condition characterized by the appearance of brown or gray-brown patches on the skin, typically on the face. It is often caused by hormonal changes, such as those that occur during pregnancy or with the use of birth control pills. West Dermatology’s professional dermatology treatments for melasma typically involve the use of topical creams or chemical peels. These treatments work by exfoliating the top layer of skin, reducing the appearance of dark spots, and promoting the growth of new, healthy skin.
