Mineral UV Filter formulas avoid the use of nanoparticles. In contrast, a refined dispersion of micronized ZnO and TiO2 in non-comedogenic flexible silicones and high volatility allows the formulations to remain extremely light by optimizing the amount of blocking agents. Our formulation uses mainly ZnO for its protective effects (because in addition to reflecting / refracting light, ZnO is also capable of absorbing UV rays without creating oxygen radicals) and the support TiO2 it contains is only in rutile form (there is no a form of anatase). TiO2 is used at all since it is an aggressive producer of free radicals.
The technologies shared in the formulas of the mineral UV filters are:
