A Comprehensive Guide to Skin-Care Acids
“Trichloroacetic acid is often used in chemical peels. Doctors will apply 20-35 percent or higher-strength peels to the face. After four to six days, the skin will peel, leaving younger, smoother skin beneath. Ascorbic acid or vitamin C is excellent for brightening the skin and stimulating collagen. Hyaluronic acid is best known for plumping (Juvaderm and Restylane) and hydrating. HA is able to absorb over 1,000 times its body weight in water, leading to fuller, more hydrated skin and thus decreasing fine lines. It’s found in the skin naturally but decreases with age.”
