Summers have begun due to which people in the United States of America have started loathing on sunscreen lotions, thinking that it will be able to protect their skin from ultraviolet rays of the sun.

However, that thinking may not prove helpful since it is wrong. The SPF, or sun protection factor, shows people how efficient a sunscreen is at giving protection from the ultraviolet B rays, the kind that causes five-alarm sunburns.

But there is no comparable measure for ultraviolet A rays, which tans skin but as well can cause cancer and wrinkles. More frequently than not, product labels are of modest help in this section.

There is good news and bad news on the ultraviolet A facade. On the benefit side, the Food and Drug Administration is trying to consider a set of guiding principles for sunscreen that would place a four-star system for efficiency of the kind of protection it offers against UVA rays.

The rules would also forbid the usage of deceptive terms such as ‘sun block’ and all-day protection from labels.

The bad news is that these measures had been proposed three years back and yet no certainty is there regarding what is to come in future.
