Fungas for tanning in

Fungas for tanning in the Sun have a different degree of protection, which is customary to measure in SPF (from the English Sun Protection Factor — sunscreen). SPF index can be from 2 to 50. This figure means how many times after using the cream you can increase the time spent on the sun. So, if on your skin the first tan appears after half an hour of staying on the sun, then protecting it with SPF 10 cream, you can sunbathe ten times longer, that is, five hours in a row. Theoretically. Practically, after all, this is not worth doing.
