DermUV
UV Protection for Hiking
UV increases ~10–12% per 1,000 m of elevation. Trail switchbacks, snow patches, and open ridgelines can double effective exposure.
Recommended gear
For hiking, DermUV recommends SPF 50+ and a reapply interval around 90 minutes, adjusted for sweat, water, and reflection.
Checklist
SPF 50+ broad-spectrum (sweat-resistant) Lightweight UPF 50 sun shirt + sun gloves Wide-brim hat or full-brim cap with neck cape Polarized UV400 sunglasses SPF 30 lip balm (lips burn fast and are easy to forget)
