Glycolic Acid

Because it is able to penetrate skin layers very effectively, glycolic acid is widely used in many skin care products, usually as an exfoliating agent or as a peel administered by a dermatologist. In clinical settings, glycolic acid concentrations up to 70% are used. For at-home use, common concentrations are between 10 and 20 percent.

The acidity or pH is also an important factor regarding the strength of glycolic acid. Medical strength preparations can have a pH a low as 0.6. For use at home, the pH of these products is about 2.5.

The primary benefit of glycolic acid is to enhance the texture and appearance of your skin. It has also been shown to be effective to minimize adult acne, wrinkles, scars and discolorations.

When applied to your skin, glycolic acid will react with the epidermis, where it breaks down the "glue" that binds the old, dead skin cells together. This process allows the outer layers of skin to be sloughed off and reveals fresh, new skin.

An excellent wrinkle reducing skincare product containing 10% glycolic acid that can be used as an exfoliating agent and cleanser is Exfoliate Me.
