Modern science has made incredible advances in protecting us against harmful solar carcinogens. However, new research has revealed grave effects from formulas we once believed to protect us. Nanoparticles, tiny, unstable atoms found in countless cosmetic and sunscreens, boost absorption and prevent white residue. Due to their small size, they easily penetrate cells altering the DNA structure, accelerating cell mutation, and leading to serious cancer risks. DéfenseThymine uses exclusive SOL-R actives, free of cancer-causing nanoparticles, providing the most complete UV protection guaranteed all-natural and 100% safe. It also is embedded with a series of natural ingredients - like macademia nut oil, neroli floral water, and zinc oxide - that work together to stimulate the skin to protect itself, whilst moisturizing extensively into the deepest layers of the skin.
