The word 'astringent' is used to describe something that causes a tightening or drying sensation. It can refer to a substance that tightens the skin, reduces inflammation, or constricts blood vessels. Astringents are commonly found in skincare products, such as toners or acne treatments, and can also be used in medicine to treat conditions like bleeding or diarrhea. It is important to use astringents in moderation, as they can be harsh on the skin and cause irritation if overused.
