glycerin

Description

Glycerin, also known as glycerol, is a versatile and widely used humectant in skincare formulations. This colorless, odorless, and viscous liquid is derived from both natural and synthetic sources. Its primary function is to attract and retain moisture, making it an essential ingredient in hydrating products.

Glycerin's molecular structure allows it to penetrate the skin's outer layer, enhancing its ability to draw water from the environment and deeper skin layers. This property helps maintain skin hydration, improve skin barrier function, and promote a smoother, more supple complexion. Additionally, glycerin exhibits emollient properties, which can help soften and soothe dry or irritated skin.

In skincare formulations, glycerin is typically used at concentrations ranging from 2% to 15%, depending on the product type and desired effects. It is compatible with most other skincare ingredients and can be found in various products, including moisturizers, serums, cleansers, and toners. Glycerin's hygroscopic nature also makes it valuable in stabilizing formulations and preventing product drying.

While generally well-tolerated, some individuals may experience temporary tackiness or stickiness when products contain high concentrations of glycerin. Overall, glycerin remains a staple ingredient in skincare due to its effectiveness and versatility.
