Chantecaille's newest sun-care formula protects skin, and specifically collagen, in three distinct and effective ways: 1. This truly invisible shield increases skin's natural ability to protect itself from UVA and UVB rays by 50-fold. The formula contains a combination of three highly effective, stabilized, non-penetrating screens: avobenzone, octisalate, octinoxate. 2. Cherry blossom, lemon balm and white tea extracts deliver powerful anti-inflammatory properties, protecting DNA from internal (ROS) and external (UVA) oxidation. 3. Carnosine, an effective and well-known anti-glycation ingredient, ensures that skin is protected from the internal threat of sugar glycation (AGE). Advanced Glycation End Products are the spontaneous result of sugar metabolism in the body. Carnosine intercepts excess sugar AGEs before they are able to attack and degrade healthy collagen.
