It sounds more like a mythical curse than restorative skincare ingredient, but don’t be fooled. Witch Hazel is a plant native to North America that contains leaves and bark that can be used to produce an astringent that causes skin proteins to solidify slightly. This removes excess oil from the skin and can be helpful in fighting acne. It’s also a natural antioxidant, anti-inflammatory and can help protect against free radical damage. Witch Hazel can be found in Aesop’s Bitter Orange Astringent Toner.
