Sodium PCA is the sodium salt of pyroglutamic acid (PCA), a naturally occurring substance found in human skin. As a key component of the skin's Natural Moisturising Factors (NMF), it helps maintain optimal hydration and supports a healthy epidermal barrier. Highly hygroscopic, Sodium PCA draws moisture from the surrounding environment, making it an effective humectant. It is non-comedogenic, non-irritating and contributes to a soft, hydrated feel on both skin and hair.
