2 oz. Bottle A little bit about this powerful astringent: Because witch hazel is a natural antioxidant and anti-inflammatory, it’s effective as a “free radical scavenger,” meaning it helps protect against DNA damage and tumor growth. Oxidative stress and free radical damage build up over time from exposure to things like UV light, pollution, a poor diet, stress and so on. Plants like witch hazel that are high in polyphenols are the same kind used to create anti-aging nutritional supplements that slow down disease development by protecting cells. Herbal plant therapies for skin disorders have been used for thousands of years, and today many traditional herbs are being reintroduced, studied extensively and experiencing a resurgence in popularity since many chemical treatments don’t always work or they have harsh side effects.
