Suntan lotion’s SPF and what is it all about
Saturday, July 10th, 2010
It is common knowledge that the sun’s ultraviolet radiation causes sun burns. But thanks to the wide variety of suntan lotions in the market nowadays, you would want to scream and say, ‘sun burn no more!’ for the rest of your life.
Now, due to the assortment of suntan lotions, you start to get confused which one to buy. Actually, it depends on the person’s skin type. Usually, the higher the SPF, or the Sun protection factor, the more your lotion can protect you from the harmful UV-B rays.
To understand more about the lotion’s SPF, here is an example: “a person that normally burns in 10 minutes when out in the sun without protection, could stay out 15 times longer (150 minutes) and not burn with a sunscreen SPF of 15”.
