Battle of the Sunscreens, Higher SPF isn't Always Better

KCAU/KNWA-- With summer's arrival, most parents are packing sunscreen in their to-go bags.
But a warning before you lather up-- a higher SPF doesn't necessarily mean more protection.
So how do you decide between 30, 50, or 100 'sun protection factor' options?
What parents often don't realize is what the s-p-f ratings actually mean.
For example, '100 plus' isn't twice as good as SPF 50.

"An SPF 30 will block about 97% of the sun's rays, and SPF 50 will block 98%," says Dermatologist Dr. Raymond Kuwahara.
"The American Academy of Dermatology recommends SPF of 30. And, any more than that there is only small incremental increase in efficacy."

Dermatologists say that re-application is more important than SPF value, anyway. So you don't need to spend extra for the SPF 100.
