The Defy Your Age Beauty Awards in the September issue of Prevention Magazine rated Avon Clearskin Professional Acne Treatment System best for adult acne. Clearskin Professional is formulated with an exclusive blend of Salicylic Acid, Glycolic Acid and an exclusive Zinc Hexapeptide-11 which work together to clear, reduce & help prevent acne blemishes, retexturize and help control surface oil in oily-prone skin.  Unlike teenagers' treatments, which often dry out adult complexions and make wrinkles more pronounced, this trio of products contains humectants that soften and smooth.  It's currently on sale for $24.99 — the lowest price ever.  And get free shipping when you shop from this link and use coupon code "FSANY."
