MEDICAL DERMATOLOGY I MELASMA
Melasma, also called chloasma, is a common skin condition in adults which causes the development of brown or greyish patches of pigmentation (colour), usually on the face. Most people develop melasma on their cheeks, bridge of their nose, forehead, chin, and above their upper lip. This skin discolouration or pigmentation doesn't cause any physical harm but may make one feel self-conscious about the way they look.
Melasma becomes more noticeable during summer and improves in winter. Though the exact cause is still unclear, melasma is thought to develop when pigment-producing cells in the skin (melanocytes) produce too much pigment (melanin).
Melasma can develop as a result of pregnancy and using hormonal drugs such as birth control pills and hormone replacement.
Sun protection is a vital treatment for melasma involving wearing sunscreen every day and reapplying the product every two hours.
