Zinc PCA is a physiological sebum-regulating active composed of zinc and pyrrolidone carboxylic acid (L-PCA), designed to treat oily skin with acne-prone tendencies. Zinc regulates sebum production by inhibiting the enzyme 5-α reductase and possesses antiseptic properties that limit bacterial proliferation, helping to prevent acne. This ingredient is ideal for oily and acne-prone skin, as it controls excess sebum, improves barrier function, and promotes cell regeneration, keeping the skin balanced and clean.
