Trusted by skin care professionals around the world, TIZO products avoid chemical sunscreens that can penetrate into the bloodstream and stay away from parabens, gluten, fragrances, and dyes. Mineral sunscreens (Titanium Dioxide and Zinc Oxide) are by far the best choice for your skin, your body, and the environment. All TIZO Mineral Sunscreen are made with raw materials that are “best available”, meaning they are medical grade quality.
