This extra strength formulation is ideal for experienced AHA users with oily skin and those who prefer a light, non–greasy and fast–absorbing gel. Glycolic Acid helps correct the visible signs of photoaging such as enlarged pores, uneven texture, pigment and enhances collagen for firmer, younger looking skin. As a highly effective exfoliant, this formula can also be used to help relieve ingrown hairs associated with pseudofolliculitis barbae.
