Zinc PCA is the zinc salt of L-Pyrrolidone Carboxylic Acid (L-PCA), derived from the cyclization of L-glutamic acid. It combines the anti-seborrheic and antiseptic properties of zinc with the moisturizing and bioavailability-enhancing functions of L-PCA. This dual action helps regulate sebum production, control acne, and limit bacterial proliferation, while reinforcing the skin barrier. Naturally present in the body as part of the "natural moisturizing factor," Zinc PCA also aids in reducing water loss, making it highly effective for cosmetic and dermatological applications.
