Glycolic acid

Glycolic acid (hydroxyacetic acid) — the most commonly used form of alpha hydroxy acids (AHAs) and one of the most effective ingredients in today’s skin-rejuvenation business. It works on both the epidermis and dermis. Scientists and formulators believe glycolic acid has greater penetration potential largely due to its smaller molecular weight. Glycolic Acid dissolves the “glue” that holds dead skin cells together in the epidermis, reduces corneocyte cohesion, allowing these dead skin cells to be easily dissolved or exfoliated to reveal new skin underneath and eventually building the thickness of the epidermis. In the dermis, it increases ground substance (boosts collagen...
