What are the Advantages of Chemical-free Sunscreens?
Chemical Free sunscreens have the advantage of immediately starting to protect when you put them on. In contrast, chemical products need to be put on 30 minutes in advance to give the skin the time to absorb them. Another significant advantage is that any sunscreen which contains the physical blocker zinc oxide or titanium dioxide will protect against both UVA and UVB rays. You can read more about suns UVA and UVB rays here. Studies show that unlike other common sunscreen chemicals, little to no zinc and titanium get absorbed through the skin, and they provide stable UVA protection relative to the other ingredients. However, zinc and titanium in spray or powder sunscreens are not recommended, since inhalation of zinc and titanium particles is a concern.
