Glycerin, also known as glycerol, is a humectant (that attracts and retains water) present in natural lipids (the link between cells that ensures water retention in the skin barrier). In skincare, it helps provide balance and hydration, contributing to healthy function and appearance of the skin. It works best when combined with other emollient ingredients that can soften dry, flaky skin. Glycerin within skincare can be naturally derived or synthetic.
