Hello summer! I thought I'd give a little lesson today. SPF (Sun Protection Factor) is actually a multiplier for your personal burn time. Let's take my g-friend Melissa. She can go in the sun for about 3 minutes (unprotected) until she burns. If she wears an SPF 10 sunscreen - she has 30 minutes (3 X 10) of protection. There are some catches. This only works for sunscreens up to SPF 30. After that, they seem to break down faster. So SPF 70 will protect you longer, but probably not 210 minutes in Melissa's case. Two different rays hit us - UVA and UVB. UVB's give us Vit D and cause us to sunburn. UVA's tan us, age us and cause deadly cancer. Remember, how you used to get a "protector" tan for your vacation? Yeah, those are the same rays that cause cancer!
Please read carefully - the QUALITY of sunscreen makes a huge difference. Many sunscreens on the market don't block UVA's. As far as I can tell from my research, the FDA doesn't even monitor UVA claims. So what's a girl to do? Here's a couple of ingredients to look for: zinc oxide, titanium dioxide, avobenzone, and ecamsule (aka Mexoryl). My advice is to wear sunscreen YEAR ROUND, every day, no matter what, under your makeup. Even if your makup has an SPF in it, it's going to destabilize faster and wear away with the color. And of course, stay out of the sun as much as you can! My personal fave for great UVA protection that is NOT greasy at all:
Neutrogena's Healthy Defense Daily Moisturizer SPF 45 which has a super fancy Helioplex stabilizer in it. You won't notice it at all. It's a great all around moisturizer for most skin types. Happy summer!
