Melasma is a common skin problem. The condition causes dark, discolored patches or freckle-like spots on the skin. It typically occurs on the face and is symmetrical, with matching marks on both sides of the face.

Causes of Melasma

Melasma’s exact etiology is unknown, however genetics, hormone changes, and sun exposure are thought to have a role. Women are more likely to experience it, particularly during pregnancy or while using birth control pills. Melasma develops when melanocytes, the skin pigment-producing cells, overproduce pigment in particular regions, resulting in the development of dark patches. Because UV rays encourage the production of melanin, which can result in the patches becoming darker, exposure to the sun can exacerbate melasma.

  • Pregnancy, birth control pills and hormonal changes can trigger melasma. This is why melasma is also used by the name  “pregnancy mask”.
  • Genetics plays a significant role in the occurrence of melasma. Brown-skinned women and identical twins are more prone to it.
  • Ingredients present in medicines and makeup products can also cause melasma.
  • Tanning beds produce UV rays that can damage the skin and cause this disorder.
  • LED lights from our mobiles, television, and laptop screens may also lead to melasma development.
