Glycolic acid is used in many personal care and cosmetics products, and is the most popular active ingredient in anti-aging formulations. It stimulates cellular activity on the skin, reducing the appearance of fine lines and wrinkles. Once applied, glycolic acid reacts with the upper layer of the epidermis, weakening the binding properties of the lipids that hold the dead skin cells together. This allows the stratum corneum to be exfoliated, exposing live skin cells. It is also proven to offer unique advantages in hair care with the proven ability to penetrate the hair shaft, causing significant benefits to hair moisturization, softness, strength and manageability.
