Sodium Allantoin PCA
What is Sodium Allantoin PCA?
Sodium Allantoin PCA is a synthetic salt derived from allantoin, a compound originally extracted from comfrey plants or produced chemically, and pyrrolidone carboxylic acid (PCA), a naturally occurring amino acid derivative in human skin. This ingredient enhances the water solubility of allantoin, making it suitable for cosmetic formulations. Primarily categorized as a skin conditioning-humectant, it works by drawing moisture into the skin's upper layers and helping to lock it in place. Commonly found in moisturizers, creams, lotions, and serums, it supports the skin's barrier function by promoting hydration without greasiness. Its mild nature stems from the soothing properties of allantoin and the humectant action of PCA, which mimics components of the skin's natural moisturizing factor.
