In daily life, we often get glycerin. In fact, it has a good moisturizing effect. Many friends like to use it as a skin care product to wipe hands. So, what exactly is glycerin? Does it have any other effect? When is glycerin used? How to use glycerin for whitening skin care? Let’s take a look.
What is glycerin?
Glycerol is the backbone component of triglyceride molecules. When the human body consumes edible fat, the triglyceride therein is metabolized by metabolism in the body to form glycerol and stored in the fat cells.
In winter, people often rub a little glycerin on the panel in order to resist drying.
Glycerin, which everyone recognizes: a colorless, odorless, sweet, viscous oily liquid.
However, the true face of glycerin is completely different, pure glycerin is a white crystal. It melts at 17 °C. Ordinary glycerin is hard to solidify because it contains some moisture or impurities.
Glycerol has a sweet taste, which is related to its molecular structure. Chemically, a group formed by a hydrogen atom and an oxygen atom, OH, is called a hydroxyl group. In general, the more hydroxyl groups contained in monosaccharides (such as glucose and fructose) and disaccharides (such as sucrose and maltose), the sweeter it is. Glycerin is similar to a monosaccharide molecule and contains three hydroxyl groups in its molecule, so it also has a sweet taste.
Glycerin is the “guard” of the panel, because it absorbs moisture, not only protects the panel, but also prevents the north from coming in – the cold current takes away moisture, prevents cracking, and it can also get water from the cold current!
When is glycerin used?
1. Glycerin is used well when the panel is dry.
Because glycerin has water absorption and is used when the panel is dry, glycerin can absorb moisture from the air to moisturize the panel, and form a water-locking film on the surface of the skin to slow the loss of moisture in the panel and keep the panel moist for a long time. Improve dry panels.
2, glycerin is used well when preparing to sleep
The absorption of our panels at night will be enhanced, so glycerin will be applied before going to bed to keep the panel moisturized for one night, and to protect the skin from dust at night to keep the panel clean. So the next day the panel is hydrated.
3, glycerin is used when going out
Glue the glycerin on the panel before going out, which can protect the skin from segregation, because glycerin can protect the skin from a part of the external environment, and can avoid the moisture loss of the panel due to wind blowing. The use of glycerin in winter also has the effect of preventing frostbite and freezing.

1, should not use hot water
Hot water can completely remove the facial protective film. After washing the face with hot water and soap, the panel of the person will feel very tight and uncomfortable. In fact, even in the harsh winter, you don’t need to wash your face with hot water. You can wash away the dust on your face with cold water. At the same time, you can also exercise the facial blood vessels and nerves and wake up the brain.
2, should not use wet towels
A long-lasting towel is good for all kinds of microbes, and rubbing your face with a wet towel is like applying a variety of bacteria to your face. Towels should always be kept clean and dry. Wash your hands with your hands and dry them with a dry towel. It is quick and hygienic.
After washing your face, you must dry it or the water on your face will evaporate on your own, causing the skin to cool and the blood vessels to shrink, causing the panel to dry, peeling and cracking and wrinkles. Moreover, we must dry the face before using the skin care products. .

3, should not use the washbasin
Not to mention whether the washbasin is clean, just say wash your face, after the face and face interaction, it is getting more and more embarrassing, and finally ends with uncleanness. It is better to wash your face with water by hand; first wash your hands and wash your face with your hands. One hand is cleaner than a handful, and it will be completely clean.
4, should not use soap
The facial panel has a large number of sebaceous glands and sweat glands, and a natural “high-grade cosmetic cream” is synthesized every moment, forming an invisible protective film on the panel. It is slightly acidic and has a strong bactericidal skin care effect. Alkaline soap not only destroys its protective effect, but also stimulates the sebaceous glands to produce more oil.
4, glycerin for cosmetic use lotion
Aqueous glycerin can be used as a lotion, and because of the safety of glycerin, the mm of many sensitive panels can be used with confidence. However, for the reasons mentioned above, glycerin alone does not completely lock the moisture, so after applying glycerin, apply a layer of body lotion.
5, hand and foot crack prevention
In addition to hand creams, glycerin can also be used. If allantoin can be added to glycerin, the anti-cracking effect is even better. Usually I will have a bottle of glycerin in the office, rub my hands at any time, and apply hand cream in the morning and evening. This winter is still very moist.
6, lip crack prevention
In fact, glycerin can also be used in the lips, and it is very effective. But be careful, it is best not to eat into your mouth.
Pay attention to the use of glycerin
1, what air drying is not suitable for glycerin
Glycerin is water-absorbent and absorbs moisture from the air to moisturize the skin. This is a method that is suitable for use in areas with a humid air. In air-dried areas, the moisture in the air is too small, the glycerin can not be absorbed, it will absorb the moisture in the panel, and the panel will become more and more dry. Therefore, it is best to use glycerin with air humidity above 50%.
2, pure glycerin should be diluted after use
100% pure glycerin can not be used directly, not only stimulate the panel, but also quickly absorb the moisture of the panel, let the skin dry and peel, and make the panel airtight. However, the bottled glycerin that we usually buy at pharmacies and supermarkets is a diluted glycerin solution that can be used with confidence.
3, do not use homemade glycerin
Nowadays, many people have the idea of making homemade glycerin. Although homemade glycerin is easy, but the environment and conditions of homemade glycerin are not up to standard, the aqueous solution is easy to breed bacteria, and the preservative is added to the glycerin. Take a 30% ratio and accidentally damage the panel. Therefore, it is best to use glycerin to go to pharmacies and supermarkets to buy ready-made.
Conclusion: In life, glycerin is mixed in skin care products for everyone to use, generally not diluted glycerin can not be directly applied to the face and body. Glycerin has a very light water absorption effect and absorbs moisture from the air to moisturize our skin. If it is in a dry place, glycerin cannot be absorbed. Therefore, you can use it according to the recommendations of the above small series
