What SPF should a person use out in the sun?

We recommend that everyone use sunscreen with sun protection factor (SPF) of 30 or higher when you spend time outdoors. SPF 30 will protect against approximately 97\% of UVB rays. Sunscreens with SPF greater than 50 provide only a very small increase in protection against UV radiation.

What SPF is best for working outside?

What does SPF 30 mean on sunscreen?

The SPF number tells you how long the sun’s UV radiation would take to redden your skin when using the product exactly as directed versus the amount of time without any sunscreen. So ideally, with SPF 30 it would take you 30 times longer to burn than if you weren’t wearing sunscreen. An SPF 30 allows about 3 percent of UVB rays to hit your skin.

How long can you stay in the Sun with SPF 15?

Sunscreen SPF and Skin Protection If your skin would normally burn after 10 minutes in the sun, applying an SPF 15 sunscreen would allow you to stay in the sun without burning for approximately 150 minutes (a factor of 15 times longer). This is a rough estimate that depends on skin type, intensity of sunlight and amount of sunscreen used.
