Foeniculum Vulgare (fennel) extract is a plant-derived ingredient used in skincare for its antioxidant, soothing, and mild antimicrobial properties, attributed to compounds like anethole and flavonoids. It is commonly included in formulations marketed for calming or refreshing effects.
| Reported effect | How often | Notes |
|---|---|---|
Allergic contact dermatitis | Uncommon | Sensitization can occur, particularly in individuals allergic to other Apiaceae (carrot/celery) family plants. |
Skin irritation or redness | Uncommon | Mild irritation may occur, more likely with higher concentrations or essential oil forms. |
Photosensitivity | Rare | Furanocoumarin content in some preparations may theoretically increase sun sensitivity. |
Estrogenic concern | Very rare | Anethole has weak estrogen-like activity in studies; topical relevance is considered minimal but noted in research. |
