Ingredient Glycerin (propane-1,2,3-triol) is a humectant moisturiser that draws moisture up through skin layers and slows or prevents excessive drying and evaporation.
Humectant means it has the property of attracting water to itself. It is essentially like a sponge that pulls in water to the outer skin layer. It can attract water from the deeper skin layers or even the air in humid environments.
Ingredient glycerin is a colorless and odorless, viscous liquid that is sweet-tasting and non-toxic. It is generally obtained from plant and animal sources. It contains three alcohol groups and is used as an “alcohol-free” alternative to. Such products are not “alcohol-free” in a scientific sense. It comes down on how easily it evaporates.
Alcohol groups are great at holding onto water, but if the whole molecule then flies off your skin (like ethanol does), that doesn’t help. In glycerin, the extra alcohol groups actually means that it sticks to water, other glycerin molecules and other things in your skin. That means it stays on your skin and acts as a hydrating humectant moisturiser.
Glycerin is dissolved in the water. It is not heat sensitive and mixes well at all desired concentrations. Due to its water-attracting properties, glycerin significantly stabilizes the structure of emulsions and improves it’s consistency.
Products containing glycerin leaves your skin with an overall moisturizing and smoothing effect.
It creates a very pleasant, soft feeling on the skin and helps maintain moisture levels in the skin. Due to the strong hygroscopic effect of glycerin, it can have a drying effect in high doses. Studies show that 5% glycerol is more moisturizing than 10%. It means that a concentration starting of 10% in emulsions, the effects of glycerin can be drying, which is not desirable for the skin. At a concentration of 3-5% glycerin provides a good moisturizing effect, as well as perfect skin tolerance. Higher concentrations may cause a sticky sensation on the skin.
Due to having antimicrobial and antiviral properties it is widely used wound and burn treatments. The Red Cross reports that an 85% solution of glycerin shows bactericidal and antiviral effects, and wounds treated with glycerin show reduced inflammation after roughly 2 hours.*
In short, it’s a skin secret weapon!
