Skin Cancer Foundation — Sunscreen
Quick Summary
The Skin Cancer Foundation's standing patient-facing reference page on sunscreen. It explains how to read a sunscreen label, what SPF and broad-spectrum mean, and how the Foundation positions its daily-use recommendation: a broad-spectrum SPF 30 or higher every day, with SPF 50 or higher for extended outdoor activity.

What Studied
Not a study. This is an institutional patient-education reference from the Skin Cancer Foundation, a non-profit dermatology-aligned authority. It compiles the Foundation's consumer guidance on sunscreen selection and daily use into one canonical landing page.
Main Findings
The page recommends a broad-spectrum SPF 30 or higher sunscreen for daily use and SPF 50 or higher for extended outdoor time. It notes that SPF 30 blocks roughly 97% of UVB and that the gain from higher SPF numbers is incremental rather than transformative. It also covers application amount, reapplication cadence, and the difference between mineral and chemical filter classes at the appearance-and-feel level rather than at a safety-verdict level.
Why It Matters
For a daily-SPF Question, this is one of the two most frequently cited non-regulatory consumer authorities (alongside the AAD). It corroborates the broad-spectrum, SPF-30+, daily-use core recommendation and gives the page's daily-wear claim institutional density without leaning on any single source.
