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.

My favorite nighttime serum of all time. Clears up acne but without any irritation due to all the hydrating ingredients. All you need is about three drops and its enough to do the job. If I have an extra stubborn pimple I'll add a bit extra to the spot and it will be greatly reduced by morning
