How Do Sunscreens Work?


Sunscreeens work by blocking UVB and UVA rays, and active ingredients are divided into organic and inorganic.

Organic active ingredients work by absorbing and dispersing the energy of the sun. Inorganic ingredients act by blocking and reflecting. There are also inactive ingredients which are in sunscreens, and these give the sunscreen its characteristic feel, help keep it stable and prevent it from spoiling.
