Astringents are skincare products that can help cleanse skin, tighten pores, and dry out oil. They are liquid-based formulas, usually containing isopropyl (rubbing alcohol), but natural astringents with alcohol from botanicals and even alcohol-free astringents are also available. Astringents work best for oily, acne-prone skin, as they help remove excess oil and unclog pores. They can be used to help shrink the appearance of pores, tighten skin, cleanse irritants from skin, reduce inflammation, reduce acne, and provide anti-bacterial benefits. Astringents affect keratin, a skin protein that contains salt bonds, which are broken by temperature changes, causing the skin to swell. Astringents have a cooling effect on the skin, thus reforming the salt bonds and tightening the skin.
Some common ingredients in astringents include alcohol, witch hazel, citric acid, and salicylic acid. Astringents for oily skin may contain alcohol, witch hazel, citric acid, or salicylic acid. However, alcohol-based astringents should be avoided if you have dry skin, as they may dry out your skin and make acne worse. Toners, on the other hand, can be used on more skin types, including sensitive, dry, and combination skin, and may contain a range of active ingredients, which may or may not include astringents.
Some astringent ingredients people may find in their skincare include isopropyl alcohol, witch hazel, calamine, green or black tea. A product that contains a mild astringent may benefit some people with oily or acne-prone skin, as it may help remove debris, makeup, or excess oil, clear acne-causing bacteria, and reduce inflammation due to its anti-inflammatory properties.
It is important to note that if your face feels red, hot, or irritated after using an astringent, you should discontinue use immediately. Astringents may have side effects, such as dryness, irritation, and redness, especially if you have sensitive skin. If you are unsure whether an astringent is right for you, consult with a dermatologist or healthcare provider. Astringents can be bought at local pharmacies, drug stores, or online.
