Ascorbyl Palmitate and fungal acne
May trigger · Moderate evidence
Why it's a potential trigger
Vitamin C esterified to palmitic acid; same acid-driven basis as the merged Ascorbyl Tetraisopalmitate row.

Evidence strength
Moderate evidence (2/3)
Function
Fatty ester
Fatty esters: split by the yeast’s enzymes into edible fats.
