3 Things to Know About Broad Spectrum Sunscreen

Broad spectrum means UVA and UVB protection UVB rays burn your skin, while UVA rays cause aging and deeper damage. Most sunscreens block UVB well, but only those labeled “broad spectrum” guarantee UVA protection too.

The FDA requires a specific test for the label If a sunscreen says “broad spectrum SPF 30,” the SPF 30 covers UVB, and the UVA protection meets a required threshold. Sunscreens that only say SPF without mentioning UVA should be avoided.

Not all sunscreens offer UVA protection Some products list SPF but never mention broad spectrum or UVA. Always check the label—if it doesn’t say broad spectrum, it likely lacks adequate UVA coverage.
