I came across the term 'SPF' and I'm not sure what it stands for or represents. I've seen it in a few contexts, but I don't have a clear understanding of its meaning. Can someone explain what 'SPF' means?

SPF stands for sun protection factor.

This metric is used to indicate the level of protection a sunscreen offers against ultraviolet B (UVB) rays.

The number that follows SPF provides an estimate of how much longer you can stay in the sun without burning compared to if you were not wearing any sunscreen.

For instance, SPF 50 means that if it takes you 10 minutes to start burning without protection, it will take you 50 times longer, which is about 8 hours and 20 minutes, to burn with SPF 50 applied.

Higher SPF values do not necessarily mean better protection, as other factors such as reapplication frequency and proper usage also play a role.
