Overview
Melasma, or chloasma, is most common in pregnant women but can affect both genders and people of all ages. It appears as blotchy, tan or brown areas of skin discoloration, and primarily affects the cheeks, forehead and upper lips. Melasma that occurs during pregnancy may fade without treatment. When skin discoloration does not disappear, or when it is of significant cosmetic concern or develops outside of pregnancy, treatment with chemical peels can fade the skin and improve its appearance. Chemical peels burn away damaged and discolored layers of the skin.
Step 1
Discontinue using oral contraceptives and any other medications that may be causing or contributing to your melasma. If you are pregnant or have recently given birth, your dermatologist may instruct you to wait before undergoing a chemical peel to determine if your melasma will disappear on its own.
Step 2
Use Retin A or an alphahydroxy acid cream to thin the surface layer of your skin prior to undergoing a chemical peel. According to the American Society of Plastic Surgeons, pre-treatment with these medications will help the chemical peel penetrate into deeper layers of your skin and improve your results. You may need to use a topical pre-treatment for as long as one month before your peel, depending on the extent of your skin discoloration.
Step 3
Try a superficial, or “lunchtime,” peel to treat mild cases of melasma. This type of chemical peel is safe for all skin colors and takes 30 minutes or less to perform. While superficial peels can remove some skin discoloration, the American Academy of Dermatology states that three to five peels may be necessary to completely even your skin tone.
Step 4
Undergo a medium-depth peel with trichloroacetic acid (TCA). This type of peel is generally the most effective for melasma, but you may still require more than one procedure to obtain clear skin. The American Society of Plastic Surgeons recommends visiting a certified dermatologist to minimize recovery time, reduce the risk of scarring and ensure the best results from your TCA peel.
Step 5
Wear a sunscreen every day, even when it is cloudy outside. Exposure to the sun’s UV radiation can trigger melasma and interfere with treatment, according to the American Academy of Dermatology. Look for a product with an SPF of 30 or greater that protects against both UVA and UVB radiation.
