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.

Glucose is a simple sugar and is the most important source of energy in all organisms. In skincare, glucose is used to hydrate the skin. It also acts as a prebiotic for our natural biome.

Our skin's natural microbiome contains many saccharides that act as prebiotics. These prebiotics help strengthen our skin's microbiome. Having a healthy microbiome helps protect our skin from harmful bacteria and other contaminants.

Studies show glucose may help with fading discoloration and pigmentation. This is because our skin metabolizes glucose into lactic acid. Lactic acid is an AHA that helps exfoliate the top layer of skin.
