Chemical peels can reverse signs of aging and can correct minor scarring usually caused by inflammatory acne. The products used in chemical peels are extremely acidic; they work by burning the top layer of the skin, which contains dead skin cells, revealing new cells. It also promotes collagen growth.
A trichloroacetic peel is a medium-strength peels that can be used to reduce wrinkles, or sometimes to treat actinic keratosis, a precancerous lesion. These peels are stronger and affect deeper tissues than alpha-hydroxy (AHA) peels, which means they can provide greater benefits. Unfortunately, it also means they will be more painful and recovery time will be longer.
