You don't need to be the next Einstein to distinguish the good antiaging creams from the bad ones. Quite a few don't live up to their claims, but this brainy formula is truly effective at banishing existing wrinkles and delaying the onset of new lines. Backed by years' worth of research and clinical studies, it's made with a potent form of keratin protein that works with the biological systems of the skin to stimulate cell growth.
