| Reported effect | How often | Notes |
|---|---|---|
Allergic contact reactions in tree-nut allergic individuals | Rare | Topical use is generally considered low-risk because refined oils contain little protein, but caution is advised in those with hazelnut allergy. |
Skin irritation or redness | Rare | Occasional sensitivity, more likely with unrefined or oxidized oil. |
Comedogenicity / clogged pores | Uncommon | Considered low on the comedogenic scale, but possible in acne-prone individuals. |
Reactions from oxidized (rancid) oil | Very rare | Degraded oil may cause irritation; proper storage reduces risk. |
