Mineral Sunscreen Works Differently- It’s Better.
A mineral sunscreen is just what it sounds like—a sunscreen that uses minerals as its active ingredients. The minerals most often used are zinc oxide and titanium dioxide. ... Mineral sunscreens are sometimes called physical sunscreens because they provide a physical barrier between your skin and the sun's rays. Plus, they are not absorbed by the skin, so they are advantageous for those who have sensitive, easily irritated or young skin. Mineral sunscreens start protecting skin immediately, so there is a very short wait time after application.
Chemical sunscreens contain organic (carbon-based) compounds, such as oxybenzone, octinoxate, octisalate and avobenzone, which create a chemical reaction and work by changing UV rays into heat, then releasing that heat from the skin. They are often referred to as chemical or organic absorbers. Some chemical sunscreens are not photo-stable and do not protect against broad spectrum UV light. Chemical sunscreens should be applied 20 to 30 minutes prior to sun exposure, giving them adequate time to form a protective layer in the skin. Since chemical sunscreens are absorbed, some people with sensitive skin react to them.
