Glycolic Acid

A multi-functional AHA (alpha hydroxy acid) that not only can function as a pH adjuster in formulations, but also has exfoliating properties and many other skin benefits.

Unlike other exfoliators, glycolic acid’s small molecular structure allows it to easily penetrate through dead skin cells, revealing smoother skin overnight. However, its benefits increase with sustained, consistent use, and if used at a high enough percentage. Over time benefits include reducing the appearance of sun damage, helping to smooth out lines and wrinkles, plus firming the skin.

Glycolic Acid has also been shown to significantly increase innate gene expression of hyaluronic acid and collagen. Studies show that when you get to 8% glycolic acid, you start seeing an increase in collagen levels in the dermis, the deeper layer of the skin. When using products containing glycolic acid always apply daily sunscreen as it increases the skin’s sensitivity to the sun.

Dr. Whitney Bowe Beauty’s Exfoliation Night Resurfacing + Brightening Serum is formulated with 8% glycolic acid, plus BHAs and PHAs to reach a total acid concentration of 12%.
