Witch hazel (Hamamelis virginiana) is a plant-derived extract rich in tannins used as an astringent, mild anti-inflammatory, and soothing agent in toners and topical products. It can temporarily tighten skin and reduce minor irritation.

| Irritation or stinging | Uncommon | More likely on sensitive or compromised skin, often related to alcohol content in distillates. |
