What it is
This extract is obtained from the leaves of Hamamelis virginiana, the North American witch hazel shrub. It is rich in tannins and other polyphenols, which give it traditional astringent and skin-conditioning properties. In sunscreens and other leave-on products it is typically used at low levels to support a soothing, conditioned feel.
Safety & warnings
Witch hazel extracts are generally well tolerated topically. Because they contain tannins and the leaf extract may be prepared with solvents, sensitive or very dry skin can occasionally find astringent preparations drying or mildly irritating. It is not classified among the regulated fragrance allergens, though any botanical extract carries a small potential for sensitization in predisposed individuals.
