RICHLAND, Wash. - Doctors want to make sure people spending time outdoors this summer are using the right kind of sunscreen. More importantly, dermatologists say get a sunscreen that protects against UVA and UVB rays.
To fight UVB rays, which cause sunburns, doctors say your best bet is SPF 30. They say a lower SPF isn't safe, and anything higher isn't worth it.
"Anything below a 30, you're really not getting enough protection. Anything above 30, there's not a lot of difference. So the difference between SPF 30 and SPF 50 is minimal," said Dr. Sidney Smith, a dermatologist at Demahealth Dermatology in Richland.
Smith also says check the sunscreen's ingredients to make sure it protects against UVA rays. He says any type with zinc, titanium, or avobenzo is a safe bet.
