I'm am horrible about sunscreen.  I don't think when I leave the house I need to put it on.  I had my first sunburn of the season in early April.  I was outside doing a live broadcast and when I got home I noticed my legs were red and hurting.  Yep sunburned legs and feet are not fun.

So when choosing a sunscreen what should you choose?  What is up with all the SPF stuff.

Well according toe the Skincancer.org:

Most sunscreens with an SPF of 15 or higher do an excellent job of protecting against UVB. SPF — or Sun Protection Factor — is a measure of a sunscreen's ability to prevent UVB from damaging the skin. Here's how it works: If it takes 20 minutes for your unprotected skin to start turning red, using an SPF 15 sunscreen theoretically prevents reddening 15 times longer — about five hours.

Another way to look at it is in terms of percentages: SPF 15 filters out approximately 93 percent of all incoming UVB rays. SPF 30 keeps out 97 percent and SPF 50 keeps out 98 percent. They may seem like negligible differences, but if you are light-sensitive, or have a history of skin cancer, those extra percentages will make a difference. And as you can see, no sunscreen can block all UV rays.

But there are problems with the SPF model: First, no sunscreen, regardless of strength, should be expected to stay effective longer than two hours without reapplication. Second, "reddening" of the skin is a reaction to UVB rays alone and tells you little about what UVA damage you may be getting. Plenty of damage can be done without the red flag of sunburn being raised.

So if you are heading out to the lake or and outdoor BBQ for Memorial Day don't forget to slather on the sunscreen or you might end up looking like these people!
