Glycerin is an ingredient that can be found in many beauty products because of its moisture locking properties. It is a form of sugar alcohol that is available naturally in vegetable oils and can also be the byproduct of soap making. Glycerin is a humectant, or hygroscopic in nature. Humectants attract moisture from the epidermis and the environment to the surface layers of the skin. Apart from moisturizing, it also has cleansing, lubricating and soothing properties.
Glycerin is known to be very beneficial for skin and hair. Here is a list of what glycerin is known to be used for:
• Absorbs moisture – It can absorb and retain moisture from the air to keep the skin well-toned, moisturized and hydrated. Using products with this ingredient improves the hydration of the outer skin layer. It also decreases the intensity of melanin, a skin darkening pigment. However, it wil not improve hyperpigmentation.
• Strengthens skin barrier – It increases the thickness of the epidermal layer and improves barrier function. This means that the harmful chemicals stay out of the skin and moisture stays in.
• Removes dead cells – Our skin cells are held together with the help of proteins. These proteins also clump the dead cells together which prevents new ones from forming. What is useful about glycerin, is that it helps the process by breaking down the proteins and removing the dead cells.
• Heals – The substance is also able to guide cells to grow and mature more effectively, thus helping the skin heal. Glycerin can also act as a natural medication for fungal infections like eczema and psoriasis, by reducing bruising and helping the infected tissue and cells to repair themselves more quickly.
Due to its different benefits as listed above, the answer to the question of what is glycerin useful for can be found in several skin care products.
• Soap – Glycerin is found most commonly in different kinds of soaps. Soaps that have this ingredient in them tend to be less drying on the skin. They are also milder and gentler, making them suitable for children.
• Cleanser – Cleansers with infused glycerin can be used on both oily and dry skin. They can remove makeup and impurities gently. Before purchasing, it is important to look for a cleanser without irritating fragrances or preservatives.
• Moisturizer – Because it can retain moisture, glycerin is an important ingredient in moisturizers. It hydrates the skin and also prevents environmental factors from degrading the skin further. For some people, “oil-free” moisturizers may be more beneficial, as these types of moisturizers do not contain oils that may clog pores.
Glycerin is also used in other skincare products like body lotions, toners and cosmetics. Topically, this ingredient is usually safe for all types of skin. It can also be used to remove blackheads. Using glycerin lip balm before going to bed is an excellent remedy for dry and chapped lips.

• While natural glycerin is good for skin, some forms of synthetic version of this ingredient, found in some skincare products, can be harmful.
