Science
Mechanism of Action
As the potassium salt of pyrrolidone carboxylic acid (PCA), Potassium PCA is a natural constituent of the skin's intercellular matrix. It functions primarily as a humectant, efficiently drawing moisture from the environment and binding it within the skin's layers to ensure sustained hydration. Furthermore, its electrolytic properties contribute to reinforcing the skin's barrier integrity and support the natural desquamation (shedding) process, aiding in maintaining a smooth and healthy complexion.
