The Ordinary range of Mineral UV Filters formulas’ offer SPF protection along with antioxidant, hydration, & anti-irritant support. The Mineral UV Filter formulas avoid the use of any nanoparticles. Instead, a refined dispersion of micronized Zn O & Ti O2 in flexible, high-volatility, non-comedogenic silicones allows the formulations to remain extremely lightweight by optimising the amount of the blocking agents. These formulation uses mainly Zn O for its protective effects (because in addition to reflecting/refracting light, Zn O is actually also able to absorb UV rays without creating oxygen radicals) & the supporting Ti O2 that it contains is only in rutile form (no anatase form of Ti O2 is used at all since it's an aggressive producer of free radicals). The technologies shared in Mineral UV Filter Formulas’ are: Bio-Active Antioxidant Network A potent combination that scavenges & neutralizes free radicals, minimizes the intensity of UV radiation penetrating the skin, visibly protects biological membranes & supports the skin response to UV exposure. Bio-Sugar Complex A unique blend of hygroscopic molecules with Multi-layer coverage providing both short & long-term hydration & also naturally increases skin’s own capacity to hold water. Skin Identical Lipids Lipids that visibly restore the compromised barrier & prevents transepidermal water loss (TEWL). Tasmanian Pepperberry Rich in flavanones, anthocyanins, & minerals, this active technology helps to calm stressed skin, acting almost immediately. Free from alcohol, nut & gluten.
