Glycerol

Description

Glycerol, also known as glycerin, is a versatile and widely used ingredient in skincare and cosmetic formulations. This colorless, odorless, viscous liquid is a naturally occurring compound found in plant and animal tissues. Glycerol is a humectant, meaning it has the ability to attract and retain moisture from the environment, making it an excellent hydrating agent for the skin.

In skincare products, glycerol functions as an emollient, helping to soften and smooth the skin's surface. It forms a protective barrier that reduces transepidermal water loss, thereby maintaining skin hydration levels. Glycerol's hygroscopic properties also contribute to its effectiveness in treating dry, rough, and scaly skin conditions.

At a cellular level, glycerol supports the skin's natural barrier function by promoting lipid synthesis and improving stratum corneum hydration. It has been shown to enhance skin elasticity and promote wound healing. Glycerol's low molecular weight allows for easy penetration into the skin, where it can interact with aquaporins, facilitating water transport within skin cells.

Glycerol is generally well-tolerated by most skin types and is considered safe for long-term use in cosmetic formulations.
