This innovative moisturizer is clinically tested to protect skin for 8 hours from pollution with a patented complex of antioxidants including polyphenols, vitamin C, vitamin E, and spruce extract. This "anti-cell burnout complex" is combined with hydrating high molecular weight hyaluronic acid to form a smooth veil on the skin which shields the skin from pollution particles. Airborne pollution is proven to form free radicals in the skin, which cause inflammation and contribute to skin aging (wrinkles and dark spots) and skin cancer, so defense against pollution damage is important to healthy skin and this product provides great environmental protection.
