Formulated with glycolic acid, the smallest and most effective alpha hydroxy acid in skin care, Jan Marini Bioglycolic products provide chemical resurfacing for a smoother, brighter complexion. Glyolic acid acts to eliminate the bonds that keep dead, dull and rough cells on the skin, and by cutting this bond, helps to diminish poor skin texture. Glycolic acid is also thought to stimulate collagen production, which increases the skin's volume to diminish fine lines. This wide range of products can perceptively rejuvenate the skin, with fewer discolorations, rough spots and lines, as well as scars such as those from acne.
