Peppermint (Mentha piperita) extract is a botanical ingredient containing menthol and other volatile compounds, used in skincare for its cooling sensation, fragrance, and mild astringent properties. It is most often included for sensory effect rather than as a primary therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation | Common | Menthol and volatile oils can cause stinging, burning, or redness, especially on sensitive or compromised skin. |
| Allergic contact dermatitis | Uncommon | Sensitization to menthol or related terpenes can produce eczematous reactions. |
| Cooling-related paradoxical irritation | Uncommon | The cooling sensation may mask irritation or worsen sensitivity over time. |
| Photosensitivity | Rare | Some botanical extracts may increase sun sensitivity, though this is less established for peppermint. |
| Mucosal irritation | Rare | Contact with eyes or mucous membranes can cause significant irritation. |
