Natural cosmetics sunscreens are mineral sunscreens. The principle of the operation of mineral sunscreens is physical: small pigments Create a thin, protective film on the skin, which reflects the UV rays from skin like a mirror. Physical sunscreen agents are not absorbed into the skin such as chemical sunscreens. They are well tolerated and cause allergic symptoms only rarely, which makes them well suited also for sensitive skin and children. In addition, the mineral sunscreen protection effect does not have to be expected, but starts immediately upon spreading.
The significant difference between chemical and physical sunscreens is that the energy of the sun accelerates the degradation of chemical UV filters, which means that their effect deteriorates immediately after reaching the light, while the physical protectors of the sun do not weaken.
