Sunscreens are divided into 2 types: physical sunscreens and chemical sunscreens:
Chemical sunscreens work by absorbing UV rays before they penetrate your skin. This type of sunscreen often contains ingredients such as avobenzone, oxybenzone, or octinoxate.
Physical sunscreens work by creating a barrier on the skin that reflects or scatters UV rays. They often contain ingredients such as zinc oxide or titanium dioxide.
Some sunscreens may also be labeled as "natural sunscreens," which usually refers to physical sunscreens that contain zinc oxide or titanium dioxide.
In addition, there are combination sunscreens that contain both chemical and physical filters to provide broad spectrum protection.
