I actually have a tough time sometimes with this, I also have a Goldilocks issue with vitamin c serums too because ascorbic acid depending on percentage and formulation irritates my skin. I think I went through everyone version of vitamin c the Ordinary had and could only use three of them 🥲

Yep! SAP, MAP, ascorbyl Glucoside, ethyl 3 O or THD are okay for me they don’t burn me
