How does sunscreen stop skin from burning?
In: Biology
Sunscreen contains chemicals that absorb or reflect ultraviolet (UV) light before it can reach your skin and damage it.
Common active ingredients in sunscreen include: oxybenzone, avobenzone, octisalate, octocrylene, homosalate and octinoxate, all of which absorb UV light.
Mineral sunscreens use zinc oxide and/or titanium dioxide, which reflect UV light.
