Description
Zinc PCA (Zinc Pyrrolidone Carboxylate) is a highly effective, multifunctional cosmetic active widely used in acne-control, oil-control, and seborrhea-care formulations. Derived from the natural amino acid L-PCA, it combines the sebum-balancing benefits of zinc with the hydrating properties of PCA, making it ideal for oily, acne-prone, and combination skin. Known for its ability to reduce shine, tighten pores, and support clearer-looking skin, Zinc PCA is a preferred ingredient in modern skincare, haircare, and scalp-care products. It is water-soluble, gentle, and suitable for both leave-on and rinse-off formulations.
