Homonym: Astringent (Taste)
An astringent is a substance that causes the contraction of body tissues, often used to reduce bleeding or tighten skin. Commonly found in products like toners and facial masks, astringents help remove excess oil and minimize the appearance of pores. They can be derived from natural sources, such as witch hazel or vinegar, or created synthetically.
In addition to skincare, astringents have medical applications. They can be used to treat minor cuts and abrasions by promoting clotting and reducing inflammation. Some foods, like unripe bananas and pomegranates, also have astringent properties, which can create a dry, puckering sensation in the mouth.
