Digalloyl Trioleate and fungal acne
May trigger · Moderate evidence
Why it's a potential trigger
An ester carrying three oleic-acid (C18:1) chains in Malassezia yeast's uptake range; extracellular lipases free the fatty half, like the ruled triglyceride oils.
Korea-only filter-system emollient. Oleic halves match the ruled oil family; not individually feeding-tested.
Evidence strength
Moderate evidence (2/3)
Function
Fatty ester
Fatty esters: split by the yeast’s enzymes into edible fats.

Questions
Does Digalloyl Trioleate trigger fungal acne?
We flag it as a potential trigger (moderate evidence). That means it belongs to a class the Malassezia yeast is known to feed on — not that every product with it will cause a flare. Concentration, formulation and individual skin chemistry matter.
