In our reference data, Isomerized Linoleic Acid can feed Malassezia (fungal acne).
Isomerized linoleic acid is a conjugated form of the essential fatty acid linoleic acid, used in skincare for its emollient and skin-conditioning properties and as a component supporting the skin barrier. It is sometimes included for purported skin-brightening and antioxidant effects, though clinical evidence is limited.

|---|---|---|
| Mild skin irritation or redness | Uncommon | Transient irritation possible, especially on sensitive or compromised skin. |
| Contact dermatitis / allergic sensitization | Rare | Allergic reactions to fatty acid derivatives are infrequently reported. |
| Comedogenicity (clogged pores) | Rare | Fatty acid derivatives may rarely contribute to follicular occlusion in acne-prone individuals. |
