What is it?
Zinc PCA (zinc pyrrolidone carboxylic acid) is a skincare ingredient that combines zinc, an essential mineral, with PCA (pyrrolidone carboxylic acid), a derivative of the amino acid proline. It is known for its sebum-regulating, purifying, and soothing properties, making it a popular choice in products targeting oily skin.
Where does it come from?
Zinc PCA is a compound created by combining zinc with PCA, a naturally occurring substance in the skin that can maintain hydration and a vibrant skin barrier. While zinc is a mineral found in many foods, such as meat, seafood, and legumes, PCA is derived from glutamic acid, which is abundant in the human body and many plant and animal sources. The combination of these two components in skincare products provides a unique blend of benefits for the skin.
