The protected amount of sunlight-induced skin redness caused by the amount of light that induces redness SPF is divided unprotected. A sunscreen with an SPF of 15 filters 92% of UVB. Sunscreen with a sun protection factor of 15 to the onset of sunburn in a person who would otherwise burn in 10 minutes to slow burn in 150 minutes. The SPF 15 sunscreen can keep a person in the sun 15 times longer. Currently, there is no measure of UVA absorption unification. There are broad-spectrum sunscreens that protect against both UVA and UVB rays, but it is important to remember that the SPF does not offer protection against UVA.
