Melasma is difficult to treat and does not always need treatment as it is not a dangerous skin condition. Some spots will go away in time with a change of hormones. However, if necessary, a doctor can prescribe certain topical creams and medications. If this does not work, a dermatological procedure, such as a chemical peel, may be performed. Some laser treatments can also reduce the appearance of melasma.
There is no real prevention for melasma other than proper skin care, such as wearing daily sunscreen and practicing other forms of safe skincare.
