Zinc PCA is the zinc salt of pyrrolidone carboxylic acid, combining the sebum-regulating and antimicrobial properties of zinc with the moisture-retaining benefits of PCA. It effectively reduces excess oil production, inhibits acne-causing bacteria, and soothes irritation, making it ideal for oily, acne-prone, and sensitive skin types. Zinc PCA also contributes to maintaining skin hydration while providing anti-inflammatory and odor-neutralizing benefits.
