Detailed answer

Melasma is a condition characterized by the development of dark patches on the skin, usually on the face. It is caused by an overproduction of melanin, the pigment that gives color to our skin. While melasma itself does not directly affect skin perspiration, certain factors associated with melasma, such as sun exposure and hormonal changes, can indirectly impact the skin's ability to perspire. Sun exposure can lead to heat-related effects on the skin, which may affect perspiration. Hormonal fluctuations, particularly during pregnancy or with the use of hormonal medications, can also influence perspiration. However, it is important to note that these effects on perspiration are not specific to melasma alone and can occur with other skin conditions or factors as well.
