Using a custom combination of low molecular weight antioxidants, Skin Actives Antioxidant Serum helps fight free radicals formed by exposure to the sun, pollution, and heat better than Vitamin C alone. Our Antioxidant Serum contains our exclusive proteins Superoxide Dismutase, Glutathione and Thioredoxin from ROS* BioNet for superior antioxidant performance. Its oil-free sea kelp bioferment base is both an anti-inflammatory and prebiotic and works well on all skin types. The deep, rich red-orange color is from the astaxanthin which is a powerful carotinoid known for its anti-inflammatory, anti aging and antioxidant effect on skin. Use Antioxidant Serum on your face, neck and décolletage to provide the nutrients your skin needs for overall health and vitality.
