Melasma

Melasma (also known as chloasma faciei or the mask of pregnancy when it occurs in pregnant women) is a common skin disorder characterized by tan, brown, or grayish hyperpigmented patches, usually on the face.

The exact cause of melasma is not fully understood, but it is believed to result from a combination of factors including ultraviolet (UV) radiation exposure, hormonal influences (such as pregnancy or the use of oral contraceptives and hormone replacement therapy), genetics, and skin irritation.

Although melasma can affect anyone, it occurs more frequently in women, particularly those with darker skin types and those living in areas of intense sun exposure. It is considered a chronic and relapsing condition that may require ongoing management.
