Glucose

Humectant

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.

Glucose is hydrating due to its humectant property. As a humectant, glucose draws moisture from the air and from deeper levels in the skin.

Our skin contains many sugars that act as prebiotics and help strengthen our natural 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.
