Hamamelis Virginiana (witch hazel) extract is derived from the leaves, bark, and twigs of the witch hazel plant and is valued for its tannin content, providing astringent, anti-inflammatory, and antioxidant properties. It is commonly used in toners and after-shave products to tighten skin and reduce minor irritation.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness | Common | The astringent tannins and alcohol often present in extracts can dehydrate skin with frequent use. |
| Irritation or stinging | Uncommon | More likely on sensitive or compromised skin, particularly with high tannin or ethanol content. |
| Allergic contact dermatitis | Rare | Sensitization reactions have been documented in case reports. |
