About HAMAMELIS VIRGINIANA BARK/TWIG EXTRACT
Witch hazel bark extract containing tannins with astringent and anti-inflammatory properties commonly used in toning and soothing skincare.
Detailed Analysis
Hamamelis virginiana (witch hazel) bark and twig extract is rich in hamamelitannins, condensed tannins, and gallic acid, providing astringent, anti-inflammatory, and antioxidant effects. CosIng lists it as an astringent and skin conditioning agent. The EU CosIng entry shows no restrictions. Witch hazel water (the steam-distilled product) differs from the hydroglycolic extract—the extract retains more tannins. IS clinical use at typical concentrations (1–10%) is considered safe; very high concentrations may cause tannin-related irritation.
