Chloasma is a common skin condition that causes brown or gray patches on the face, particularly on the forehead, cheeks, and nose. This condition is also known as "melasma" or "pregnancy mask," as it frequently occurs in pregnant women due to hormonal changes. Other synonyms for chloasma include "facial hyperpigmentation," "dark spots," "skin discoloration," and "brown patches." Chloasma can be triggered by sun exposure, hormonal changes, genetics, and certain medications. While it is not a serious medical condition, chloasma can impact a person's self-esteem and confidence. Treatment options include topical creams, chemical peels, and laser therapy. Regular use of sunscreen and protective clothing can also prevent chloasma from worsening.
