Sodium pyrrolidone carboxylate (PCA-Na) is the main component in the stratum corneum of the skin and one of the natural moisturizing factors. Zinc pyrrolidone carboxylate (PCA-Zn) replaces the sodium ions with zinc ions with antibacterial effect, and provides moisturizing effect and excellent antibacterial performance for the skin at the same time. Numerous scientific studies have shown that zinc can reduce the excessive secretion of sebum by inhibiting 5-a reductase. Supplementing zinc to the skin helps to maintain the normal metabolism of the skin, because the synthesis of DNA, cell division, protein synthesis and the activity of various enzymes in human tissues are inseparable from zinc.
