British researchers recently patented the compound salicyloyl-phytosphingosine (SP), a combination of exfoliating salicylic acid and a moisturizing fatty acid similar to skin's own protective oils. Studies show that SP helps fade sunspots and reduce fine lines. "Unlike many OTC anti-agers, this duo speeds cell turnover minus any irritation," says Neil Sadick, MD, a clinical professor at Weill Cornell Medical College. Expect SP products on store shelves soon.
