sun protection factor |
The SPF is the ratio of the time required to produce minimal erythema on skin covered by a sunscreen product to the time required to produce the same degree of erythema without the sunscreen. If you usually turn red after 10 minutes unprotected in the sun, next time you use a sunscreen with SPF 15 you can stay 150 minutes in the sun without getting a sunburn. But this ration may lead to a false security since studies have shown that people using a higher sunscreen tend to stay 20 % longer in the sun which is not necessarily the intention of sun screen. |
