Question: Good afternoon! Why is glycerin added to Faberlic products? I heard that in low humidity this ingredient does not moisturize the skin, but harms it. In addition, it is a cheap ingredient that is not traditionally used in most high-quality products.

Expert Answer: Glycerin is an integral component of the hydrolipid mantle of the skin.

Studies show that not only does the ingredient have good moisturizing properties, but it also can stabilize the protective functions of the skin.

It is proven that glycerin has a positive effect on the elasticity of the skin, by supporting the liquid crystalline structure of the stratum corneum. The "behavior" of glycerin in the body, its interaction with other substances, and its effect on skin health has long and thoroughly been studied in cosmetology.

Since glycerin is naturally used within the body, it is perfectly tolerated and never acts as an allergen. It is an effective moisturizer. It has been known for many years as a substance that binds a liquid. One molecule of glycerin can "bind" ten molecules of water! Glycerin is not the most expensive ingredient, but it is a time-tested and effective moisturizer that does not cause allergic reactions.

Can glycerin dry the skin? Yes, it can, but only if you apply pure glycerin on the skin while in a dry climate.

But glycerin is never used in its pure form in skin creams. All our creams contain up to 80% water, which is bound by glycerin. The concentration of glycerin is usually from 0.5 to 5%. Of course, sometimes there are products with a higher concentration of glycerin, but the developers don’t do this to reduce the cost of the formula, but to create certain effects on the skin, since it is very important for people with overly dry, flaky skin.
