Why sunscreens fail SPF tests: All about SPF testing

About

I’m Michelle, a science educator and chemistry PhD from Sydney, Australia. I’m here to help you work out which beauty products are worth buying and which aren’t, using science! I started Lab Muffin because I was frustrated that there weren't enough easy-to-understand explanations of the science behind beauty products. I firmly believe that anyone can understand the science behind skincare and beauty. For business/PR enquiries: [email protected] DISCLAIMER: I am not a medical doctor.
