5 Reasons Broad Spectrum Sunscreen Is the Only Kind Worth Buying

Broad spectrum protects against both UVA and UVB rays Sunscreen without “broad spectrum” on the label only blocks UVB rays that cause sunburn, not UVA rays that cause premature aging and skin cancer.

SPF alone is misleading SPF measures only UVB protection. A high SPF number does not guarantee UVA protection, so you can get a false sense of security.

UVA rays are constant and penetrating UVA rays are less intense than UVB but more constant—they go through clouds and car windows. Without broad spectrum, you are unprotected from them all day.

Broad spectrum is the baseline, not a bonus It is not a luxury feature. It is the minimum requirement for effective sun protection. If a sunscreen lacks it, it is incomplete.

Look for “broad spectrum” or PA++++ In the US, check for “broad spectrum.” In Asian sunscreens, look for a PA++++ rating. If the label only says SPF 50 with no other indication, skip it.
