Glycerin plays a significant role in skincare primarily because of its ability to attract and retain moisture. It is a humectant, which means it helps bind water to the skin, keeping it hydrated and preventing dryness. This property makes glycerin particularly effective in a variety of skincare formulations, as it can help maintain the skin's moisture balance, making it feel softer and more supple.

In practical terms, by drawing moisture from the air and from deeper layers of the skin, glycerin aids in improving the skin's overall texture and appearance. It is often included in lotions, creams, and serums to enhance hydration. This is important for maintaining skin health, especially for individuals with dry or dehydrated skin.

While other options may refer to different functions of ingredients in skincare, they do not accurately describe glycerin's primary role. For instance, while exfoliants are used to remove dead skin cells, glycerin does not perform this function. Similarly, glycerin does not act as an oil; instead, it provides moisture without adding greasiness, and it does not have an effect on skin temperature. Understanding the specific function of glycerin helps estheticians choose the right products for addressing various skin concerns.
