TotTotal Block Tinted SPF 60 is unique in its ability to protect the skin from the full light spectrum and prevent cellular environmental damage to the skin, regardless of the source of these pollutants. Total Block SPF 60 incorporates eight forms of mill-dispersed solids, ranging in controlled particle-size from 10 microns down to a few nanometers. These particles are suspended homogeneously to achieve maximum protection throughout the entire UVB/UVA range. Micro-dispersed particles shield the skin from atmospheric damage and trauma. Eight forms of micronized and sub-micronized particles of titanium dioxide, sub-micronized zinc oxide, along with ultra-micronized iron oxide form the foundation for a wall of reflection and refraction.
