Zinc PCA contains the zinc salt of L-pyrrolidone carboxylic acid. L-pyroglutamate (PCA), a derivative of glutamic acid (an amino acid) is very hygroscopic, and is one of the skin’s natural moisturizing factors. Zinc PCA offers the benefits of PCA and those of zinc. Zinc PCA can decrease the redness and irritation caused by acne, as well as reducing oiliness.
