what SPF do you really need?

With summer basically here we are all going to be spending some time outdoors. We all know how important sunscreen is, so I'm not going to ramble on and on about it. Because if you're like me, you get a little tired of every single magazine talking about the risks of being in the sun. We get it!!!
How do you know what type of SPF is right for you? Is it really necessary to use SPF 100? The answer is no!!! Here's what some of the leading dermatologists are saying about what kind of protection we need to be using for our days in the sun. 
There is no sunscreen or SPF that completely protects us from the suns UVA and UVB rays. If you use an SPF of 15 you are getting protection for about two hours. It will protect you from 94% of those harmful rays. SPF 30 blocks about 97%. From there on, these numbers don't really increase. If you from SPF of 50 to 100 the amount of protection increases by LESS that 1%! If you factor in swimming and sweating you obviously need to apply more, but as a general rule, every two hours is enough to protect your skin. If you want to be extra careful, wear a hat and protective clothing.

So here are some things to remember this summer! 
1. Apply sunscreen 30 minutes before going outside
2. Apply every two hours or more if you're swimming or sweating
3. Tanning (although it looks good) is skin damage!!!
4. From 10-3 is where the most damage can occur from the sun

Hope this helps you prepare for more happy days in the sun!!!

  1. Thanks Ginny! What about moisturizers with SPF? I heard that the SPF gets diluted, and they don't work as well as regular SPF. Is that true?
