Evidence: In a randomized controlled community trial of 903 adults under 55, daily use of a broad-spectrum SPF 15+ sunscreen slowed skin aging over 4.5 years: the daily-sunscreen group showed 24% less photoaging than the discretionary-use group (relative odds 0.76, 95% CI 0.59 to 0.98). The trial measured the act of using a broad-spectrum sunscreen.
