Heliocare 360 Mineral Tolerance Fluid SPF50 is a uniquely formulated sunscreen that provides full spectrum coverage against solar radiation and also against visible and infrared rays. This kind of protection becomes more and more important as we are increasingly surrounded by radiation other than the sun. The star of Heliocare 360 is FernblockFC, a patented extract that consists of a combination of ingredients. It contains a botanical extract, which helps increase the skin's natural defense against sun exposure, and also Caffeic Acid and Ferulic Acid which provide antioxidant protection against free radicals. In addition, the presence of biomimetic melanin provides protection against high-energy visible light, often referred to as "blue light" and oxothiazolidine protects against infrared light.
