Lets dispel a few of those myths.
What is the difference between mineral, physical, and chemical sunscreens?
Mineral or physical sunscreens are made with tiny particles of titanium dioxide or zinc oxide.
Chemical sunscreens include pretty much everything else: oxybenzone, octisalate, and others.
There are also sunscreens that combine both types of ingredients.
