This mineral sunscreen is safe for everyone in the family from Dad to baby; even the dog! The nano sized zinc particles in this sunscreen block the sun without penetrating the skin. The other benefit to mineral sunscreen is that is doesn't decompose through sun exposure, so they actually have a longer life on your skin, unlike chemical sunscreens which absorb into your skin. The mineral sunscreen also actually reflects the UV rays, so your skin never absorbs them; whereas, typical store-bought chemical sunscreens absorb the rays and release their energy in harmless ways. 

More traditional products rely on octisalate (found in 59 percent of products, according to the EWG), oxybenzone (found in 52 percent) and avobenzone (found in 49 percent). Oxybenzone presents the most concerns; it can trigger allergic reactions, is a potential hormone disrupter, and penetrates the skin in relatively large amounts, according to the EWG.
