Witch hazel is a natural astringent derived from the bark and leaves of the witch hazel plant, primarily found in North America. It is commonly used in skincare products for its ability to tighten skin and reduce inflammation. The active compounds in witch hazel, such as tannins, help to minimize pores and soothe minor skin irritations. In addition to its cosmetic uses, witch hazel is often applied to treat conditions like acne, eczema, and hemorrhoids. Its anti-inflammatory properties make it a popular choice for calming redness and irritation, making it a versatile remedy in both traditional and modern medicine.
