What role does glycerin play in skincare products?

Glycerin is recognized primarily for its role as a humectant in skincare products, which means it has the ability to attract moisture from the environment and draw it into the skin. This moisture retention is key for maintaining skin hydration, making glycerin an essential ingredient in many moisturizing formulations. By helping to increase the water content in the outer layer of the skin, glycerin contributes to a plump, healthy appearance and can help mitigate dryness and irritation.

While glycerin can have other roles in formulations, such as contributing to the overall texture of a product, its primary function is to enhance moisture retention. This is particularly beneficial in products aimed at hydrating the skin or those designed for dry skin types. The effectiveness of glycerin as a humectant is well-studied; it is considered safe for most skin types and often recommended for skincare routines.
