Our Sun Mist, My Haze 1,2,3 Sun, is nanoparticle-free: nanoparticles make skin care products fluid and long-lasting, but they are suspected of penetrating the epidermal barrier and therefore of posing a health hazard. Our suncare product respects the principle of mixing filters to ensure optimal protection. The mineral filter that reflects UV rays is Titanium Dioxide in microparticles to avoid the risk of penetrating the epidermal barrier and causing danger. The two synthetic filters that absorb UV rays are Diethylamino Hydroxybenzoyl Hexyl Benzoate and Butyl methoxydibenzoylmethane, which represent 0 to 4% of the ingredients respectively.
