Sunscreens fall into one of two categories: chemical and mineral (also sometimes called “physical”). Both help protect skin from damaging sun rays but do so in different ways.
Chemical sunscreens contain ingredients that work to absorb damaging UV rays, convert them into heat, and then release that heat through skin. Mineral sunscreens contain ingredients that act as a physical barrier between damaging UV rays and your skin—essentially working to help protect your skin from the harmful effects. Chemical sunscreens have their conveniences, but it’s always good to have options. Mineral sunscreens sit on top of the skin, start to work instantly, and tend to be preferred by people with more sensitive or reactive skin.
