Astringent medicines cause shrinkage of mucous membranes or exposed tissues and are often used internally to check discharge of serum or mucous secretions in sore throat, hemorrhage, diarrhea, or peptic ulcer. Externally applied astringents, which cause mild coagulation of skin proteins, dry, harden, and protect the skin. Mildly astringent solutions are used in the relief of such minor skin irritations as those resulting from superficial cuts, allergies, insect bites, or athlete's foot. Astringent preparations include silver nitrate, zinc oxide, calamine lotion, tincture of benzoin, and vegetable substances such as tannic and gallic acids, catechu, and oak bark.

Zinc oxide and calamine are astringents used in lotions, powders and ointments to relieve itching and chafing in various forms of dermatitis.

    Wikipedia: astringent

    An astringent substance is a chemical substance that tends to shrink or constrict body tissues, usually locally after topical medicinal application. The word "astringent" derives from Latin astringere, meaning "to bind fast". Two common examples are calamine lotion and witch hazel.

    Astringency is also the dry, puckering mouthfeel caused by tannins found in many fruits such as blackthorn, bird cherry and persimmon fruits. The tannins denature the salivary proteins, causing a rough "sandpapery" sensation in the mouth. Astringency tastes unpleasant to many mammals (including humans), which tend to avoid eating astringent fruit; conversely, birds do not taste astringency and readily eat these fruit. It is thought that fruit astringency gives a selective advantage to some plant varieties because birds are better than mammals at long-distance seed dispersal, often flying a great distance before passing the seeds in their droppings.

    Astringent substances are also found in some wines and teas. A small amount of astringency is expected in some wines, especially young red wines made from grapes such as cabernet sauvignon.

    Astringent medicines cause shrinkage of mucous membranes or exposed tissues and are often used internally to check discharge of blood serum or mucous secretions. This can happen with a sore throat, hemorrhages, diarrhea, or with peptic ulcers. Externally applied astringents, which cause mild coagulation of skin proteins, dry, harden, and protect the skin. Acne sufferers are often advised to use astringents if they have oily skin. [1] Astringents also help heal stretch marks and other scars[citation needed]. Mild astringent solutions are used in the relief of such minor skin irritations as those resulting from superficial cuts, allergies, insect bites, or fungal infections such as athlete's foot[citation needed].

    Some common astringent agents include alum, oatmeal, yarrow, witch hazel, bayberry, very cold water, and rubbing alcohol. Astringent preparations include silver nitrate, zinc oxide, zinc sulfate, Burow's solution, tincture of benzoin, and vegetable substances such as tannic and gallic acids. Balaustines are the red rose-like flowers of the pomegranate, which are very bitter to the taste. In medicine, its dried form has been used as an astringent. Some metal salts and acids have also been used as astringents.

    Apla is partially right. Both astringents and stimulants dry the skin (only necessary with facial tissue). These will dry up excess moisture such as perspiration and natural oils. The difference is that stimulants will cause a tissue reaction. This opens pores and widens any nooks in the skin. While an astringent will contract that tissue causing pore to close up. If you ever used alcohol on the skin you'll feel it kind of stretch the skin while witch hazel will make it feel more like puckering.

    An astringent is the same as a toner for the face. It is often used for oily skin. I think alcohol is little harsh to use on the face. Witch hazel is great, and was even popular in your grandma's day. It is still used as a component in many facial cosmetics today. Topical alcohol, or rubbing alcohol is used mainly as an antiseptic to kill germs on wounds, but it is also an ingredient in many cosmetics. The alcohol that you drink, such as whiskey, bourbon and scotch, is a stimulant. I hope this clears up your confusion.

    An astringent is 'a substance or preparation, such as alum, that draws together or constricts body tissues, resulting in decreased flow of blood or other secretions'.

    In the case of a toner such as witch hazel, it closes the pores and makes the skin smoother.

    Not necessary. It's a good idea to wash your face first though. You'll remove any oil better with just a wash. Astringent is better for after you take makeup off. It will help get off any left over makeup.

    Typically, skin conditions such as eczema have to do with poor dieting. Learn here https://tr.im/k0VRk

    Eczema food triggers such as eggs, fish, peanuts, and soy are known to help reduce flare-ups, but this can vary from person to person. These foods may also exacerbate eczema because many people cannot properly digest the proteins, which causes an allergic reaction.
