SPF & Sun Protection

SPF (Sun Protection Factor) indicates how much longer you can stay in the sun before burning compared to unprotected skin. SPF 30 blocks about 97% of UVB rays. The burn time depends on your skin type (MED - Minimal Erythemal Dose) and UV index. Always reapply sunscreen every 2 hours or after swimming/sweating.
