what is glycerin for skin

Glycerin is a natural compound derived from vegetable oils or animal fats. It is a humectant, which means it is a type of moisturizing agent that pulls water into the outer layer of your skin from deeper levels of your skin and the air. Glycerin is commonly used in moisturizers and lotions, and it is also a major ingredient in cosmetics. It can positively affect your skin in a number of ways, such as hydrating the outer layer of your skin, strengthening the skin barrier, and promoting healthy skin. Glycerin can penetrate the skin barrier and remain within the skin for continuous hydration for several days. However, because of its thick texture, glycerin can leave a sticky or tacky residue on the skin if used excessively. It is often diluted with other moisturizing ingredients, like hyaluronic acid, which has a lightweight, almost watery texture. Glycerin is well-tolerated and suitable for all skin types.
