Piper Nigrum (Pepper) Seed Extract is derived from black pepper seeds and is used in skincare for its antioxidant and skin-conditioning properties, attributed largely to piperine and related compounds. It is also included for purported microcirculation-stimulating and warming effects in some formulations.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or warming/tingling sensation | Uncommon | Piperine can be mildly irritating and may cause transient warmth or stinging, especially at higher concentrations. |
| Allergic contact dermatitis | Rare | Sensitization to pepper-derived components has occasionally been reported. |
| Erythema or burning sensation | Uncommon | More likely on sensitive or compromised skin due to spice-derived bioactives. |
| Increased skin penetration of other actives | Uncommon | Piperine is a known bioavailability enhancer, which may amplify effects or irritation from co-applied ingredients. |
