An astringent is a substance that causes contraction of body tissues. In skincare, astringents are used to cleanse and tone the skin. They can be applied to the skin directly or added to cleansers and toners. Astringents work by removing excess oil and dirt from the skin.
There are many natural ingredients that belong to the category of astringents. Some examples include witch hazel, apple cider vinegar, and green tea. These ingredients are often used in skincare products because of their ability to cleanse and tone the skin.
