Zinc PCA

Zinc PCA is a powerful oil-regulating and skin-balancing active that combines zinc (known for its purifying, soothing, and sebum-control benefits) with PCA (a natural moisturizing factor). It helps reduce excess oil, minimize the look of pores, support clearer skin, and maintain hydration. Ideal for acne-prone, oily, combination, and breakout-prone skin formulations.
