About HAMAMELIS VIRGINIANA BARK/LEAF EXTRACT
Witch hazel extract — a classic astringent that tightens pores and soothes inflammation. Effective for oily and acne-prone skin, but can dry out sensitive skin, especially in alcohol-based formulations.
Detailed Analysis
Hamamelis Virginiana Bark/Leaf Extract (CAS 84696-19-5) is derived from the witch hazel shrub (Hamamelidaceae). Rich in tannins, flavonoids, and gallic acid. Approved by the FDA as an OTC skin protectant. The CIR determined witch hazel-derived ingredients are safe when formulated to be non-irritating and non-sensitising. Strong astringent properties from tannins help tighten pores and reduce sebum. Studies show 10% witch hazel effectively reduces erythema. However, alcohol-containing formulations can excessively dry skin, disrupt the moisture barrier, and worsen conditions like eczema and rosacea. Rare allergic contact dermatitis reported.
