While cosmetic lasers are effective for treating cosmetic dermatological issues, one condition that even they have trouble with is Melasma, a side effect of pregnancy. Throughout this video, Dr. Schultz will explain why it's caused and how to treat it. Melasma, known as the mask of pregnancy, is a tan or brown blotchy discoloration of the forehead, below the eyes, or along the upper lip. It is very difficult to treat melasma, but there are ways to help lighten the discoloration. Dr.Schultz uses topical preparations containing exfoliants and bleaches and finds that skin care products that have either glycolic or salicylic acid combined with bleach is the best way to reduce melasma gradually. If at-home remedies are not treating it effectively, you should see a dermatologist who can do glycolic peels or salicylic acid peels.
