What is sodium PCA?
Sodium PCA or NaPCA, made from the fermentation of sugars or starches, functions in human skin as a humectant, a substance that attracts water. Without enough NaPCA in the skin, the moisture level will drop and skin will dry out. Without enough moisture, nutrients cannot be properly delivered to the skin cells. NaPCA is the most powerful, non-toxic humectant known, and the most important humectant in the skin.
