Mineral based sunscreens scatter ultraviolet rays away from the skin, they are physical solar filters.  While chemical based sunscreens absorb various wavelengths of UV radiation. My preference is to use titanium oxide and zinc oxide. Some will say that the mineral based SPF will cause cancer. To date, there is no clinical evidence stating that these solar filters pose any health threat to human skin.  We do know that exposure to the sun causes skin cancer. Please choose a SPF with greater than a 15 spf. Skin Deep uses and recommends #IS clinical Eclipse SPF 50+ tinted or beige and #Sanitas Solar Block.#Skindeepgj.com#sunscreen#skincancer
