Among superficial peels the most popular and extensively studied and evaluated peel is glycolic acid peel. Glycolic acid is naturally occurring substance found in sugarcane, pineapple & sugar beet.
Glycolic acid used for skin treatment which gently loosens the bond that holds the dead skin together ,shrink pores ,lighten spots, even out scars, lessen appearance of fine lines and keeps skin smooth and bright.
Glycolic acid boosts collagen production. Collagen is vital protein which keeps the skin firm. Glycolic acid transfer water molecules from air into skin tissue thereby replenishing the lost moisture.
Thus a product which contains free glycolic acid at 10% solution and maintain pH range of 3.5-4 will be a great product to express yourself younger.
