Glycerin also known as glycerol or glycerine. Glycerin is a colourless liquid found in all natural fats, including those in our own skin. It naturally occurs in soap as it is a byproduct of saponification. Glycerin is a humectant, meaning that it attracts moisture to the upper layer of the skin and maintains skin’s water balance where it is applied. In this way it prevents dryness and scaling by maintaining the skin's barrier against the elements. It can also be used to promote wound healing. Glycerin is a common component of natural soaps due to its moisturising properties and its ability to cleanse gently.
