CDC — Sun Safety Facts
Quick Summary
The U.S. Centers for Disease Control and Prevention's standing public-health page on sun safety. It restates the broad-spectrum, SPF-15-or-higher floor for sunscreen labeling in the United States and packages that recommendation alongside shade, protective clothing, and the timing of outdoor exposure as a single layered public-health message.

What Studied
Not a study. This is an institutional public-health reference page from the CDC summarizing sun-safety guidance for the U.S. general population. It is positioned as the CDC's consolidated standing position on sun protection.
Main Findings
The CDC recommends sunscreen labeled "broad-spectrum" with SPF 15 or higher for general use and reapplication every two hours during active sun exposure. It states explicitly that a higher SPF does not let users stay in the sun longer — it only blocks slightly more UVB — and that combining sunscreen with shade, protective clothing, and avoidance of midday peak UV is the most effective approach.
Why It Matters
For a daily-SPF Question, the CDC source supplies independent public-health corroboration of the broad-spectrum floor and the "more SPF does not equal more time outside" framing. Pairing the CDC alongside FDA, AAD, and Skin Cancer Foundation citations gives the page convergent multi-authority backing for its daily-wear recommendation without overweighting any single source.
