Hamamelis Virginiana Leaf Extract
Hamamelis Virginiana Leaf Extract is derived from the leaves of the witch hazel shrub (Hamamelis virginiana). Unlike the bark, the leaves contain very low levels of tannins (only ~0.04%), with gallic acid being the most active component. Despite the low concentration of active compounds, the extract still exhibits soothing, astringent, and antibacterial properties.
Provides soothing, astringent, and antibacterial benefits to the skin. The low tannin content compared to witch hazel bark means it is less likely to be irritating while still delivering mild active effects. Gallic acid, its primary active component, contributes to its antimicrobial character.
The low tannin content is generally considered a benefit, as high tannin levels can be very astringent and irritating to the skin; no specific contraindications are noted in the source.
