Coffee Seed Oil and fungal acne
May trigger · Moderate evidence
Why it's a potential trigger
Rich in linoleic and related C18 unsaturated fats — the core menu Malassezia yeast harvests once its lipases split the oil's triglycerides.
Explicit row under the fatty-oil rule (same basis as the ruled seed oils); not individually feeding-tested.
Evidence strength
Moderate evidence (2/3)
Function
Oil
