Sunscreen 101

By  | 

Even when it's overcast, dermatologists say you can still get a sunburn. We headed out to Sparks Marina to talk to some bathing beauties and find out who's following the rules of sun protection.

"Are you wearing sunscreen? Yeah, on my nose. Only on your nose?!"

"Do you wear sunscreen? Yeah, I am wearing 30 SPF right now. Do you always? No."

At least Dallas Scurry and Alicia Kraft are lifeguard came away with a pretty painful burn...and he admits, he wasn't wearing enough sun block. Dermatologists recommend sunscreen with a sun protection factor of 30 or higher, but any protection is good protection.

"An SPF of 15 is adequate sun protection, as long as you apply consistently and appropriately," said Dr. Kimberly Kolar, M.D.

Which means, covering up at least 30 minutes before sun exposure, and re-application every two hours. The important thing is to look for sunscreen with both UVA and UVB on the bottle, which protect you from skin cancer and aging.

"I go to Walmart to buy my kids sunscreen. It doesn't have to be expensive. Price is not as important as ingredients," said Kolar.

Things like zinc oxide, titanium dioxide and helio-plex are all crucial, if you want to bask in the rays while summer is still around.

"As long as you have sunscreen on, you don't have to sit under an umbrella or live in a cave."
