The Two Most Important Sunscreen Ingredients

Neutrogena Sunscreen SPF 55

I found a really interesting article on Everyday Health today that talks about some of the misconceptions about sunscreen, and some ingredients you need to look for when shopping for sunscreen this summer.  Here are some highlights from the article, that you can read here:

1.  The two most important ingredients when shopping for sunscreen is a) zinc oxide; and b) titanium dioxide.  There is a third ingredient that was recently approved by the FDA called Mexoryl.

2. A big myth about sunscreen is that you get double the protection when you double the SPF.  In fact, SPF 30 is only 4% more protection than SPF 15.

3. Make sure you apply enough sunscreen to cover the areas exposed.  They recommend a tablespoon for your face (including ears), and a shotglass to cover your body (arms, legs, etc.).

4.  The last point was fairly obvious, but you should re-apply sunscreen every 3-4 hours, or after swimming or bathing.

Neutrogena has a variety of products that contain zinc oxide and titanium dioxide.  The one in the photo is the Ultra-Sheer Dry Touch Sunblock SPF 55.
