Humectant, Skin Conditioning, Skin Protecting

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.

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.

Normally I avoid products with alcohol, but it’s not an issue with this one. It’s well formulated so that it’s balanced out with other more hydrating ingredients. It absorbed nearly immediately and doesn’t dry out the skin. The results aren’t massive. But I just love the apothecary aesthetic and it works about as well as any other dark spot corrector.

Actually noticed a difference in my fine lines with this product. The bottle also lasted me over a year with almost daily use.
