Face Moisturizers by Paula's Choice. Details:This silky moisturizer superboosts hydration, evenness and radiance with a blend of powerful ingredients. First, a highly stable form of 5% vitamin C visibly lifts dullness and promotes firmness by fighting free-radical damage. Then, hexapeptide-5, lipids and polyglutamic acid strengthen the moisture barrier for lasting hydration over time. The hero ingredient in this innovative moisturizer is vitamin C, a research-supported antioxidant that does so much more than brighten tone. On its own, it can visibly firm, counteract free-radical damage and support some of skin’s most essential functions. When joined with barrier-repairing ingredients like peptides and lipids, it can also help bind in moisture for a supple, youthful complexion.
