A doctor has provided 1 answer

Melasma : Melasma is a common acquired increase in pigmentation occuring exclusively in sun-exposed areas that is typically brownish in color. It tends to be prominent (but not exclusively) among latinos and asians, and more apparent during and after periods of sun exposure. It mostly arises from pregnancy (chloasma) and oral contraceptives, but can also be associated with endocrine dysfunction, genetic factors, certain medications, nutritional deficiencies, among other things.
