iS Clinical products help protect DNA from free radical damage and oxidative stress, and this is especially important for sunscreens since DNA damage from sun exposure increases risks of skin cancer and photoaging. Data showing the DNA photoprotection conveyed by Extreme Protect SPF30 was published in the Journal of Cosmetic Dermatology. DNA in the chromosome of skin cells is an especially important structure and is responsible for reproduction into daughter cells and serves as the command center of the cell, directing the cell in how and when to do its job. There are many damaging free radical sources, including the sun, pollution, blue light, infrared light, ambient or inhaled tobacco smoke, environmental toxins, and others. Additional antioxidants and Extremozymes in iS Clinical products help protect vital DNA from free radical damage. (See White Paper “DNA Protection from iS Clinical Products.”)
