Is SPF 50 any better than SPF 15?

It's almost Summer and many of us are already day-dreaming about sunny days, sandals, bikinis and bronzed skin.  However, before we start baring more skin during the summer months, it's time to get educated about SPF and face the sun rays with the best possible knowledge AND protection.

One of the first things most people look for when purchasing sunscreen is the "SPF" number which stands for Sun Protection Factor.  SPF is simply a number representing how well the sunscreen deflects UVB rays. The SPF number is determined by the amount of time it takes for the skin to sunburn when sunscreen has been applied to the skin (compared to skin that is unprotected).

The logical assumption is that a higher SPF is a much better sunscreen, however, this can be a little misleading.  Assuming the sunscreen is applied correctly, an SPF 30 will provide slightly more protection from UVB rays than an SPF 15. However, the SPF 30 is NOT DOUBLE the protection of the SPF 15.  There is only a slight increase in the protection for your skin.

The best way to get the most out of your sunscreen is to make sure it is applied properly.  Often, sunscreen is not applied completely or is not applied thick enough.  Use about a teaspoon of sunscreen for your face and about 2-3 ounces for the body and make sure it is applied thoroughly.  If you are unsure if you have enough, opt for too much rather than too little.

Another factor in the effectiveness of your sunscreen is how often it is applied. A good rule of thumb is to re-apply every two hours.  If you are swimming or sweating, there is a very good chance the sunscreen will be wiped away or washed away leaving your skin unprotected.  In these instances, be sure to re-apply every hour to attain the greatest benefit from your sunscreen.

Last but not least, when choosing a sunscreen, find one that is a broad-spectrum sunscreen that will protect you from both UVA and UVB Rays.  If you're unsure about the different types of rays, be sure to look for next week's blog where we will explain the difference!

Have a great summer and make sure you pack your sunscreen!
