Glycerin Application The glycerin application as a moisturizer to treat or prevent dryness, roughness, scaling, itchy skin is very diverse. Glycerin can also be used to relieve minor skin irritations, such as, diaper rash in children and skin burns from radiation therapy. What is glycerin? Glycerin, also known as glycerol, is a natural compound obtained from oils or animal fat. Glycerin is a clear, syrup like, colorless, odorless, and sweet-taste liquid. Glycerin is a moisturizer that draws water from the deeper surface of the skin and air to the outer layer of the skin. In skin care products, glycerin application is usually in combination with the materials which absorb moisture, another type of moisturizer, to trap the moisture in the skin. According to an authorized study in 2016, glycerin is "the most effective moisturizer" compared to many others, including alpha hydroxy acids (such as lactic acid and glycolic acid), hyaluronic acid, propylene glycol and butylene glycol, sorbitol and urea. The difference between emollient and moisturizer We must note that there is a difference between the performance of moisturizers and emollients. Emollients are substances that soften and moisturize the skin and reduce itching and flaking. Some products (e.g., zinc oxide or kerosene) are more commonly used to protect the skin from irritation (e.g., moisture). Dry skin is caused by dehydration in the upper layer of the skin. Emollients trap water by forming an oily layer on the top layer of the skin and prevent the skin from drying out. Oil, lanolin, mineral oil and dimethicone are common emollients. Moisturizers, including glycerin, lecithin and propylene glycol are dehumidifiers. These substances draw water to the outer layer of the skin and thus remove its dryness. Many products also contain creatine that softens the top layer of the skin cells (including urea, alpha hydroxy acids, such as, lactic acid, citric, glycolic, and allantoin). The main purpose of glycerin application is helping to shed dead skin cells, leaves more water in the skin and makes the skin softer and smoother. Glycerin Applications Glycerin is known as a main ingredient in the production of moisturizers and lotions. According to a study of cosmetics in 2014, after water and fragrances, glycerin is the third most widely used ingredient in cosmetics. Purchasing and using glycerin in pure form has also become increasingly popular. Effects of glycerin applications on the skin Studies show that glycerin can have a positive effect on your skin in many ways, and it seems that using glycerin in skin care products is the right thing to do. According to an authoritative study in 2008, glycerin can hydrate the outer layer of the skin (which contains creatine), improve mechanical functions and skin barriers, protect the skin against various stimuli, and accelerate wound healing. Can glycerin irritate the skin? To moisturize the skin, glycerin gets water from the nearest source and transfers it to the top layer of your skin. The nearest source of water is actually the underlying layers of the skin. Therefore, glycerin can absorb too much water under the skin and cause dehydration and dryness. If you consume too much glycerin in different applications, your skin may get blisters due to the excessive dryness of the skin. For this reason, it is best to dilute pure glycerin before using it on the face and skin to avoid such problems. Many proponents of natural cosmetics recommend diluting glycerin with rose water, as rose water hydrates the skin and clears pores. An authoritative study in 2011 showed that roses have positive antioxidant effects on the skin. Recent studies have also shown that a combination of glycerin, hyaluronic acid and Centella asiatica extract improves the function of skin barriers within 24 hours after use. Side effects of glycerin applications Although glycerin does not appear to have many side effects, because it is a natural substance, it may cause allergic reactions. So before using it, you should make sure that you are not allergic to it. If you have severe redness on skin, itching or pimples, you should stop using this product immediately. Look for an alternative product that does not contain glycerin and be sure to read the label of the cosmetics you buy carefully. Other glycerin applications In addition to its moisturizing properties, glycerin has other uses as a medicine. For example, glycerin is also used as a hyperosmotic laxative to get water into the intestines to treat constipation. It is also used to transfer drugs to the patient's body. Glycerin can also be used as a sweetener, thickener and preservative. The health and safety of glycerin is approved by the World Food and Drug Administration (FDA). Conclusion Glycerin has many applications, but its most important use is in moisturizing the skin. Research shows that glycerin can have a positive effect on your skin. by glycerin application, the skin becomes softer. However, under certain conditions, glycerin may cause dehydration, so it must be diluted with water or other substances. be sure to consult your doctor before using glycerin to make sure that glycerin is right for you and will not have a negative effect on your current health.
