Vitabrid CG, the proprietary ingredient in Vitabrid C 12 product, stores and preserves active vitamin C bio-friendly mineral layer. Once applied to the skin, it releases active vitamin C for over 12 hours. Vitabrid CG encapsulates active vitamin C between layers of bio-friendly minerals and provides 12 hours of antioxidant vitamin C through its patented LDH technology. Our skin barrier protects the skin from external substances, making it difficult for normal vitamin C to be delivered to the skin. The ion exchange mechanism in Vitabrid CG allows active vitamin C to penetrate deep into the skin within 12 hours. Vitabrid C is specially formulated for all skin types (young and old) and scalps. All of our products are safe for use on sensitive skin to help skin look and feel healthier.
