There has been nothing to show that melasma indicates any kind of serious issues with your health, as it is a pigmentation issue and not related to any other health problems. Melasma is a common skin disorder that affects about 1% of the population and up to 50% of the population in some areas of the world, with hormones from pregnancy and birth control being one of the major triggers for women who have melasma. You can try to reduce the likelihood of melasma by using sunscreen when you are outdoors, avoiding being in direct sunlight during the peak hours of 10 AM to 4 PM and for women, using non-hormonal birth control can also help. When you are using sunscreen, it is recommended to also use a tinted sunscreen as it can help protect the skin further, as well as using sunscreen that is made with iron oxide, zinc oxide, and titanium dioxide have shown to help when outdoors. When it comes to melasma, taking care of your skin to protect it from the sun and other triggers like UV light, can help lessen the appearance of spots on the skin. One of the biggest things that studies have shown is there are psychological effects that people with melasma can have, as they can suffer from social anxiety or depression, this mainly happens in women due to the changes in their appearance.
