You may experience flashback with this sunscreen because it's a mineral sunscreen. It's contains zinc and titanium oxide. The way mineral sunscreens work when used correctly is that they provide a physical shield/block against UV rays. You may want to try a chemical sunscreen instead. Chemical sunscreens are made from organic carbon compounds that act like a filter on the skin. The sunscreen reacts with the UV rays and turns the rays into heat, a chemical reaction. Chemical sunscreens won't have the white flashback like mineral sunscreens. There are pros and cons for both formulas and it all comes down to what works better with your skin type.
