This is a controversial one! In this episode, I talk about the difference between chemical vs physical SPF and if there is even a difference?
Reapplying and is this even important? Should we be applying SPF on impaired barriers or post peel/exfoliation treatments?
The difference between a 30 & a 50 SPF! What does waterproof even mean and the missing research and evidence around coral bleaching from SPF!
