Homonym: astringent (Taste)
Astringent refers to a substance that causes the contraction of body tissues, often used to describe certain foods, medicines, or skincare products. Common examples of astringent foods include unripe bananas, pomegranates, and green apples. These items can create a dry, puckering sensation in the mouth due to their high tannin content.
In skincare, astringents are often used to tighten pores and reduce oiliness. They can help treat acne and other skin conditions by removing excess oil and impurities. Popular astringent ingredients include witch hazel and aloe vera, which are known for their soothing and tightening properties.
