Tips on sunscreen during summer heat

By  | 

GRAYSON COUNTY, Texas (KXII) -- Before families head out the door for summer fun, many choose to apply sunscreen to protect their skin.

But there are some things to keep in mind when using sunscreen.

"One of the keys things is a lot of folks look at the SPF number and kind of calculate up that, "Well, it's SPF 45 so I can put this on once and stay out all day,'" Dr. Bryan Massenburg, M.D. with Urgent Care said.

Dr. Massenburg says even if the SPF or Sun Protection Factor is high, depending on your skin and how long you're outside, you should put sunscreen on at least every hour or two.

Jessica Brown who visited Lake Texoma with her family last week followed that advice.

"If we don't reapply often, I noticed they get a little bit red, but as long as we keep reapplying about every hour and a half, then it's good. It works," Brown said.

There are different types of sunscreen from the spray to the cream.

All can be effective against sunburns if they are applied the right way.

"If you're going to be outside for a short time, you can use the spray," Dr. Massenburg said. "Make sure you get a good coating on, you'll probably be okay. With the creams and lotions though are better if you're going to be out for a long period of time."

Brown told me she preferred the cream and lotion over the spray.

"I don't like the spray for the kids, I don't like spraying it in their face," Brown said. "I don't know, it seems gross to me."

Dr. Massenburg said as long as all skin exposed to the sun is covered by some kind of sunscreen, residents will have a fun and safe summer.

"And again that's the key with the sunscreens, make sure that you have a good coding and all the expose skin is covered with the sunscreen because any skin that is not covered will be open to sunburn," Dr. Massenburg said.
