Hamamelis Virginiana (witch hazel) extract is derived from the bark and leaves of the witch hazel shrub and is used in skincare for its astringent, soothing, and antioxidant properties, largely attributed to its tannin content. It is commonly included in toners and products aimed at oily or irritated skin.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness or tightness | Common | Tannin-rich astringent action can dehydrate skin, especially in alcohol-containing formulations. |
| Mild irritation or stinging | Uncommon | More likely on sensitive or compromised skin barriers. |
| Allergic contact dermatitis | Rare | Sensitization to witch hazel or co-formulated constituents has been documented in case reports. |
| Worsening of eczema or barrier disruption | Rare | Repeated use of astringent or alcoholic preparations may aggravate certain dermatoses. |
