Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.

Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.

Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.

This ingredient is organic, colorless, odorless, and non-toxic.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Unfortunately this did not work out for me, everytime I tried to use it my skin would become red, very irritated , feeling burned and it would not go away. I had high hopes because the ingredient list was great and it was very pricey. Maybe 15% concentration is too high for me, maybe the antioxidants are too much (though my skin loves green tea)...I suspect the culprit might be Oat Extract ( I also had this red burning reaction with Aveeno Calming & Restore products which are all Oat based). I cannot say for sure what happened but this was too irritant for my skin.
