3 Things to Know About Broad Spectrum Sunscreen

Broad spectrum means protection against both UVA and UVB rays SPF only measures UVB protection, which causes sunburn. UVA rays cause premature aging and skin cancer but don’t usually burn you, so you might not notice them. Broad spectrum sunscreen has been tested to block UVA rays as well.

Most older sunscreens were UVB-only Before the FDA required broad spectrum testing, many sunscreens sold in the US only blocked UVB rays. Don’t buy a sunscreen without the “broad spectrum” label.

Skipping broad spectrum is a waste of money Without it, you’re paying to get burned slower while still getting invisible damage from UVA rays. Your future skin will thank you for choosing broad spectrum.
