astringent def review

An astringent is a substance that shrinks tissues, causing them to tighten and dry out. Astringents are commonly used in skincare products to temporarily tighten the skin, shrink pores, and remove oil. They are often used after cleansing but before moisturizing. Astringents can be made from a variety of ingredients, including alcohol, witch hazel, calamine, green or black tea, and tannins. Some astringent ingredients people may find in their skincare include isopropyl alcohol, citric acid, salicylic acid, and green or black tea. Astringents can be beneficial for people with oily or acne-prone skin, as they can help remove excess oil and unclog pores. However, alcohol-based astringents should be avoided if you have dry skin, as they can dry out the skin and make acne worse. Some common side effects of astringents include redness, irritation, and dryness. It is important to use astringents as directed and discontinue use if you experience any adverse effects.
