We count on sunscreens to protect us from the sun's harmful UV rays. The higher the SPF - the better the protection. Right?
Not necessarily. Consumer Reports tested a dozen sunscreens - both lotions and sprays. This test measures sunburn protection from UVB rays.
That's what SPF is supposed to tell you.
Sue Booth with Consumer Reports found, "Most of the sunscreens we tested provided less protection than the SPF listed on the container."
These days you'll also see the words "broad spectrum" on many sunscreens.
Sue says, "Broad spectrum means sunscreens are supposed to protect not just against UVB rays, but UVA rays as well."
Both types of rays can cause skin cancer, and UVA rays can wrinkle and age your skin.
Consumer Reports' lab tests performed both on people and on test plates coated with sunscreen found some products offer better protection than others for both UVA and UVB rays.
It has six sunscreens to recommend.
Top-rated is a spray from Target - Up and Up Sport broad spectrum SPF 50.
Sue points out, "Spray sunscreens are convenient, but the risks of inhaling them are still being studied. So we don't recommend spraying children. And don't spray directly on your face."
If you prefer a lotion, Consumer Reports named one from Walmart a Best Buy. It's Equate Ultra Protection Sunscreen Broad Spectrum SPF 50.
It offers better protection than several sunscreens tested that cost much more.
Consumer Reports also points out, sprays are flammable. So wait for the spray to dry before going near an open flame.
With any sunscreen, you should apply sunscreen 15 to 30 minutes before you head into the sun and reapply it after you take a swim or every two hours.
