Overview

Diglycerin is a moisturizing ingredient with humectant properties.

A humectant is a type of moisturizing ingredient that draws moisture onto the skin, which is as opposed to an occlusive that locks moisture into the skin. Diglycerin is very similar to its cousin ingredient, glycerin. The main difference is that diglycerin has twice the molecular size when compared to glycerin. Therefore, it is quite a bit slower to penetrate the top layers of skin.

All in all, diglycerin is a powerful ingredient for achieving moisturized skin.
