5. Be aware of Chemical and Physical Formulas
Both formulations are slightly different from each other and they play different roles. Physical sunscreen forms a physical barrier that refracts the sun rays. They contain mineral ingredients such as zinc oxide or titanium dioxide. Chemical sunscreens are absorbed into the skin where they form a chemical barrier. They contain organic compounds that react with the sun rays and release them in form of heat.
