Description
L-Pyrrolidone Carboxy Sodium (L-PCA-Na) is the main ingredient in the stratum corneum of the skin and one of the natural moisturizing factors. L-pyrrolidone zinc carboxylate (PCA-Zn) replaces the sodium ions with antibacterial zinc ions, and at the same time provides skin with moisturizing effect and excellent antibacterial properties. A large number of scientific studies have shown that zinc can reduce the excessive secretion of sebum by inhibiting 5-a reductase. Supplementing zinc to the skin helps 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.
