This week we got into the weeds about AHAs with chemist Dr Shiva Farabi. What are they, what do they do, what are the different AHAs out there and how do they differ from each other. Also explored in the episode - what are 'acids' in skincare, what's the difference between 'mechanical' and 'chemical' exfoliation, and for beginner AHA users, what's a good approach for incorporating them into your skincare routine.
