- The Natural Moisturizing Factor in Human Skin
Na-PCA is a Ph-balanced, concentrated solution of the sodium salt of pyrrolidone carboxylic acid, the natural moisturizing factor found in human skin.
How It Works:
Na-PCA is synthesized from glutamic acid, a nonessential amino acid. The skin contains natural moisturizers, the most important being Na-PCA.
Old skin contains only about half the amount of Na-PCA as that found in young skin. The ability of skin to hold moisture is directly related to its Na-PCA content. It is water, and not oil, that keeps skin soft and supple. Na-PCA keeps skin moisturized, improving its appearance, and giving it a moist and youthful glow.
After bath or shower, spray Na-PCA liberally on the hands and apply to the face and other skin areas.
