Melasma, a common skin condition that causes dark, discoloured patches on the skin. However, the condition is believed to be more common in women than men but it can affect men as well. As per the American Academy of Dermatology, 90 percent of people who get melasma are women. So what are its symptoms? Well, the symptoms include as mentioned above discolouration, dark patches on face as well as on the other areas of your body. The dark brownish patches usually appear on the cheeks, forehead, bridge of the nose and chin; however they can also appear on the neck and forearms. Although, skin discolouration does not affect you physically but it can surely make you feel self-conscious about how you look. So, why does this melasma occur? Well, the exact cause of melasma is still not known but it has been observed that people who have dark skin are at greater risk than those who have fair skin. Experts believe that it has something to do with the estrogen and progesterone sensitivity which means that birth control pills, pregnancy and hormone therapy can all trigger melasma. Apart from these, stress and thyroid diseases can also be blamed for causing melasma.
