SPF Doesn’t Mean What You Think It Means

In this video, Sci-Show goes into detail about SPF facts and what that means for us..

SPF seems pretty simple. Find a high number, rub some on your nose, and you’re ready for some sunshine. Unfortunately the science behind it is a little more complicated.

  1. Europe has a circle marker around UVA text on products but I don’t think anyone knows what it means. The UK has a star rating on the back of the bottle for UVA. The National Health Service recommends 4 stars out of five but even SPF 30 cream can be just 3 stars.
