Alpha hydroxy acids, derived from fruit and milk sugars, are used in skin care to exfoliate and diminish visible signs of aging by helping collagen and elastin production. NeoStrata's Alpha Hydroxy Acid Plus Line (dark blue labels) uses extra strength Glycolic Acid to rejuvenate the complexion and create a healthier and more youthful appearance. Ideal for dry, sun damaged, acne and aging skin. Not recommended for sensitive skin and first time use of glycolic acid products. Only use after a period of treatment with the AHA grey labelled products.
The side effect of alpha hydroxy acids is sun sensitivity, so it is important to use a high sunscreen daily.
