Piper Nigrum (Black Pepper) Seed Extract is derived from black peppercorns and contains piperine and volatile oils; it is used in skincare for its warming, circulation-stimulating and antioxidant properties, and is sometimes included for purported absorption-enhancing or invigorating effects.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation / warming sensation | Common | Piperine and aromatic compounds can cause transient tingling, warmth, or stinging, especially at higher concentrations. |
| Erythema (redness) | Uncommon | May occur on sensitive or compromised skin due to its rubefacient action. |
| Allergic contact dermatitis | Rare | Sensitization to plant constituents or fragrance components can occur in predisposed individuals. |
| Photosensitivity | Very rare | Limited reports; some Piper-derived constituents may theoretically increase sun sensitivity. |
