Overview
“One of the tricks I use all the time is to mix my favorite moisturizer with a few drops of glycerin before applying it to my skin,” says Gilbert. - It can help especially effective in the most stubborn places, such as corns on heels or hard elbows. Here you can leave it overnight so that the dead cells on the surface leave the skin faster, and the result will pleasantly surprise you. ”.
Glycerin is also an incredibly effective moisturizer if it is found in detergents. “When cleansing the skin, it is important to remove dirt and oil, this is a fact. But it’s equally important to monitor the health of the upper layer of the skin, ”said Joshua Zeitner, adding that glycerin can not only support hydration, but also prevent skin irritation during the cleansing process”.
By the way, glycerin is also almost indispensable in hair care products (especially when it comes to thin and brittle hair). The fact is that this component actively protects curls from the harmful effects of the environment and aggressive styling, plus, saturating the hair with moisture, it does not break during simple procedures such as combing or braiding, for example.
But why is it still worth being careful
“But if glycerin is such a wonderful component, then where do all these texts that should be avoided Alchera from?” You ask. And the question, we agree, is very logical. The first thing you should know about this is that most opponents of glycerin in cosmetics appeal to the fact that it is obtained from animal fats. But in the modern cosmetic industry, as we have already said, vegetable or, in extreme cases, synthetic glycerin is almost always used. In the latter, by the way, there is nothing good at all. However, you can meet it only in cheap cosmetics with AliExpress or from Benylin transition.
But even vegetable glycerin has one unpleasant feature before begin is worth keeping in mind. As we again mentioned, the main property of glycerin is to draw moisture from deeper layers of the skin or from the environment. And if you are constantly in a dry room or if there is not enough moisture in the air, glycerin will pull it just from the dermis, which with regular repetition will not affect your skin in the best way.
Glycerin can moisturize or dry your skin.
Glycerin, also known as Glycerol, is a component of all animal and vegetable fats and oils. It can also be synthesized from carbohydrates or substances such as propylene.
Glycerin is a polyhydric alcohol that can be obtained from natural sources or can be synthesized.
The presence of glycerol in cosmetics can be determined by the inscription glycerin. The glycerin content in moisturizing cosmetics is about 15-20%, and in cosmetics for softening the skin and in detergents - up to 2-5%.
Properties of glycerin used in cosmetics:
Moisturizing. Glycerin is a well-known moisturizer in cosmetics and personal care Childrens. Other features that have been reported for include glycerin, a balm-conditioning agent, an oral care agent, a skin conditioning agent, a moisturizer, skin protectant and viscosity reducing agents. Glycerin concentrates moisture in the skin, attracting additional water molecules from the outside and creating a moisturizing film on the skin.
From the point of view of cosmetologists, glycerin is considered a very controversial component. Some believe that glycerin is not only able Benylin attract water molecules from the surrounding air to the skin, but, in the case of low humidity, can, on the contrary, draw moisture from the skin, leading to its drying out. Others believe that it is important to use such glycerin-containing agents to moisturize the skin, in which water is a key component, and glycerin is dissolved in the “water in oil” type - in this case, glycerin will retain the incoming moisture in the skin. There is also a theory about special transport proteins (aquaporins) that transfer not only water molecules, but also glycerol through cell membranes. Aquaporins that transport glycerin are concentrated in the epidermis, glycerin penetrates into the intercellular space and helps to retain water in the stratum corneum of the skin, increasing its elasticity.
Emollient. Childrens penetrates into the intercellular spaces, smoothes, tones and softens the skin, as well as relieves itching of the scalp and helps get rid of dandruff.
Antiseptic. Glycerin, due to its high ability to absorb water, leads to dehydration of bacteria, therefore it is widely used in the manufacture of soap.
Protective. Glycerin restores the barrier function of the skin.
In medicine, glycerin is prescribed in the form of applications to soften the skin and mucous membranes with dermatitis, as well as an effective laxative - in the form of suppositories and suppositories. Glycerin, added to drugs instead of water, allows you to get highly concentrated medical solutions.

The use of cosmetics with glycerin is undesirable
- with individual allergy to glycerin, manifested by a slight burning of the skin
- during pregnancy, since glycerin has a strong relaxing effect (body creams)
Glycerol - A relatively recent discovery of chemists, its history of use dates back a little more than 200 years. In 1779, the Swedish scientist Karl Scheele, heating olive oil with lead oxide, discovered the release of odorless and sweet taste liquid. K. Scheele evaporated the resulting solution and obtained a heavy syrupy substance, which was later called glycerin (glicos - sweet). The newly discovered substance turned out to be very convenient to use, since it had no color and odor, did not cause allergies, and easily reacted with other chemical compounds. Glycerin began to be used unusually widely - from food additives to confectionery to the production of explosives. The peculiarity of glycerin is that it is very hygroscopic, an excellent solvent, able to increase the viscosity of liquids, to protect ointments, pastes and creams from drying out. In addition, glycerin is easy to obtain, because it is the main component of the molecule of any fat (the so-called triglyceride in chemistry) and is found in almost all effects and animal fats. Today glycerin is used in electrical and radio engineering, the manufacture of paints, varnishes and plastics, in the leather and agricultural, textile and tobacco industries, in the production of medicines, food products and cosmetics.
Where do glycerin come from for cosmetics??
According to the method of producing glycerin, it is conventionally divided into animal (obtained as a by-product of the processing of fats by soap making), vegetable (obtained, for example, by processing rapeseed oil into biodiesel) and synthetic (as a product of hydrolysis of wood flour or oil distillation). The quality of glycerol obtained does not depend on the feedstock.
Glycerin has been produced industrially since the beginning of the 19th century, open link Michel Chevrel first proposed the extraction of glycerol by saponification of fats with hydroxides. In 1853, A Tilgman proposed the breakdown of fats into fatty acids and glycerin under strong heating and high pressure. As a result, after cooling, fatty acids floated to the surface of glycerin water. After almost 40 years, scientists have proposed another way to obtain glycerin - the breakdown of fats using sulfonic acids.
