Powerful antioxidant Vitamin C protects against oxidative damage, fighting free radicals to support and boost Collagen production, resulting in skin that is firmer and brighter, with reduced fine lines and wrinkles. L-Ascorbic Acid Chirally correct L-Ascorbic Acid at 100% purity delivers transformative effects for radiance and texture, combating Collagen degradation caused by UV damage and acting as mild tyrosinase inhibitor, decreasing melanin production and reducing pigmentation. Apply once or twice a day. Mix in one tiny shake of powder (equivalent to the size of a grain of rice) with either your moisturiser, serum, mask, or sunscreen in order to activate the Vitamin C then apply to skin. Wash hands after application. Please do not mix Vitamin C 100% into Rejuvenate 15, Repair Balm, or Multi-Active Oil. Overuse could result in redness and peeling. Avoid eye area.
