Made from naturally occurring acids found in fruits and other foods, alpha hydroxy acid (AHA) peels are used to remove dead cells from the surface of the skin. AHA peels essentially work by exfoliating the skin. They loosen and remove the layer of dead cells on the skin’s surface thus revealing the smoother, healthier-looking layer below. Regular treatments can help with fine lines, brown marks and dry spots. They also can help minimize acne scarring–and even help with the treatment of acne by stripping away the plugs where acne bumps can form. They’re often combined with microdermabrasion for even greater results.
