Sodium PCA is the sodium salt of pyroglutamic acid (also known as PCA). PCA is a naturally occurring component of human skin and a part of the “natural moisturizing factors” (NMF) that maintain a healthy epidermis. Sodium PCA is very hygroscopic, attracting moisture from the air.

This PCA is sourced from all-natural, vegetable-based ingredients; it contains no animal-based ingredients of any kind.
