Copper PCA is a salt of copper and pyrrolidone carboxylic acid, which is an organic acid that occurs naturally on the surface of the skin, where it maintains moisture levels.
Copper is known to aid in the wound healing process and is a part of many important enzymes in the body.
According to the manufacturers, Copper PCA is used in skincare products for its antimicrobial and sebum-reducing properties, as well as for its ability to maintain and repair collagen and heal wounds.
None of these effects, however, have been described in the scientific literature, and so we cannot be sure if Copper PCA truly works that way.
