Sunscreen Safety in Australia with John Staton (454)

from Shirtloads of Science · host Dr Karl

This week I'm joined by John Staton, one of Australia's leading sunscreen-testing experts, to unpack the big headlines surrounding sunscreen safety. A recent Choice report revealed that 16 out of the 20 tested sunscreen products failed to meet their advertised SPF rating by a significant figure. John helps us to understand what is really going on. He breaks down how sunscreens actually work and the science behind SPF testing and why so many products fell short.
