CLAIM Accelerated retinol SA is an ingredient that works fast and is less aggravating to skin than prescription-strength retinoids; you'll see fewer lines and age spots in just one week. EXPERT OPINION "Most people can tolerate prescription-strength retinoids only several times a week," says Baltimore dermatologist Noëlle Sherber. With a dose of hyaluronic acid to improve hydration and lessen irritation, "this can be used nightly, delivering more rapid results." OUR VERDICT We spread a pea-size amount over our faces and necks every night for two weeks and soon saw a brighter complexion. Even our melasma (hormone-induced pigmentation) seemed less noticeable. After three weeks, the lines around our mouths weren't as drastic.
