Block Sunscreen
How does sunscreen block UV rays?
How is it that a layer of cream can stop a particle that travelled from the sun, punched through 50 miles of atmosphere and still has enough energy to cause a burn?
Ask the wiki:
The principal ingredients in sunscreens are usually aromatic molecules conjugated with carbonyl groups. This general structure allows the molecule to absorb high-energy ultraviolet rays and release the energy as lower-energy rays, thereby preventing the skin-damaging ultraviolet rays from reaching the skin. So, upon exposure to UV light, most of the ingredients (with the notable exception of avobenzone) do not undergo significant chemical change, allowing these ingredients to retain the UV-absorbing potency without significant photo-degradation.[1]
