Skin cancer (squamous cell)

What is SPF?

SPF stands for sun protection factor. It is given as a number.

The SPF number tells you how much protection from sunburn a sunscreen will give you.
The higher the SPF number, the longer you can stay out in the sun before you get burned.
Everyone should always use a sunscreen with an SPF of 15 or more.
