What is the difference between physical and chemical sunscreen?
It’s all in the ingredients. While physical sunscreens contain safe minerals like zinc oxide, chemical sunscreens contain toxic chemicals like oxybenzone. Natural minerals provide a physical barrier between your skin and UVA/UVB rays, so they provide effective protection by sitting on top of the skin. Chemicals, on the other hand, absorb into the skin in order to absorb UV rays and convert them into heat.
