It’s extracted from the leaves of the witch hazel shrub. As an astringent, it can leave skin feeling tighter.
The EU’s ingredient database lists it as a skin conditioner, its general term for an ingredient that keeps skin in good condition.European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗
The evidence, graded
expert consensusUS safety reviewers (2018) assessed witch hazel ingredients, which products use mostly as astringents and to condition skin. In the tests they reviewed, these ingredients generally didn’t irritate or cause allergy; a leaf extract at 0.45% caused neither in repeated patch tests. Because astringents may irritate, and these may be used near the eyes, they judged them safe in products made not to irritate or cause allergy. Their list names the leaf extract and the bark, leaf and twig extract.Cosmetic 2018 · Cosmetic Ingredient Review ↗
