a measure of how well a sunscreen will protect skin from UVB (Ultraviolet B) rays, the kind of radiation that causes sunburn, damages skin, and can contribute to skin cancer

A

SPF (Sun Protection Factor)

SPF, or Sun Protection Factor, is a measure of how much UV radiation it takes to produce sunburn on skin with sunscreen compared to how much UV exposure it takes for unprotected skin to get sunburned.

For example, if it takes 300 seconds for skin to burn with SPF 60 sunscreen, and 10 seconds to burn without it, the SPF is 60 because 300 divided by 10 equals 30. However, this doesn’t mean you can stay in the sun 60 times longer than without sunscreen.
