Laurus Nobilis (bay laurel) leaf extract is a plant-derived ingredient containing essential oils, flavonoids, and polyphenols, used in skincare for its antioxidant, antimicrobial, and soothing properties. It is most commonly included as a supportive botanical rather than a primary clinical active.
| Reported effect | How often | Notes |
|---|---|---|
| Allergic contact dermatitis | Uncommon | Bay laurel is a known contact allergen, partly due to sesquiterpene lactones (e.g., costunolide) and laurel oil. |
| Skin irritation or sensitization | Uncommon | Essential oil components may irritate sensitive or compromised skin. |
| Photosensitivity | Rare | Some botanical/essential oil constituents may increase sensitivity to UV light. |
| Cross-reactivity with other Lauraceae or sesquiterpene-lactone plants | Rare | Individuals allergic to related plants (e.g., Compositae) may react. |
