​Trichloroacetic acid (TCA) peels (sometimes called Blue Peel) in concentrations up to 50% are superficial to medium peels and have been around for years with a history of being effective and safe. This type of peel can be used for peeling the face, neck, hands, and other areas of the body. It has less bleaching effect than phenol (see below) and is excellent for "spot" peeling of specific areas. TCA peels are best for fine lines but are minimally effective on deeper wrinkling
