Emma, propanediol is a penetration enhancer. So if you’re using a lot of it with powerful actives like Vitamin C or glycolic acid, it can cause irritations.

It’s the main ingredient in one of my serum (The Ordinary Ascorbic Acid 8% + Alpha Arbutin 2%) which I am currently finding a but irritating. I put it down to the actives but I’ve been able to tolerate Ascobic Acid in past without much problem… just wondering if it could be the Propanediol instead? Thanks for a great review!
