Simmondsia Chinensis and fungal acne
May trigger · Limited evidence
Why it's a potential trigger
Possible oil — check label: Simmondsia Chinensis without a part name is ambiguous; the usual cosmetic form is the fatty oil, which feeds malassezia. If the label means the oil, treat this as a trigger.
Ambiguous bare plant name — kept visible as a possible oil instead of silent unrecognized. Check the full INCI: if the label means the oil, treat as a trigger.
