Glycerin

Glycerin is a naturally occurring humectant that serves as a cornerstone ingredient in skincare formulations due to its exceptional water-attracting properties. This simple three-carbon molecule, also known as glycerol, is a key component of the skin’s natural moisturizing factor and works by drawing moisture from both the environment and deeper skin layers to the stratum corneum. Its unique ability to penetrate skin through aquaporin-3 channels allows it to create a moisture reservoir within the skin, providing long-lasting hydration while supporting barrier function. Beyond basic moisturization, glycerin maintains optimal skin cell membrane fluidity, accelerates wound healing, and provides anti-inflammatory benefits. In skincare formulations, it functions as both a standalone hydrator and synergistic enhancer, making it invaluable for addressing dry, sensitive, or compromised skin conditions while maintaining compatibility with all skin types.
