SPF

Lotion bottle abbreviation

SPF stands for sun protection factor, a measure of how well sunscreen blocks ultraviolet radiation.

The number indicates how much longer you can stay in the sun before burning compared to unprotected skin: SPF 30 theoretically allows thirty times longer exposure.

I always use SPF 50 at the beach.

Higher numbers offer diminishing returns—SPF 30 blocks about 97% of UVB rays, SPF 50 about 98%.
