Built with 20% Niacinamide and 4% Zinc PCA, the Cos De BAHA Niacinamide 20% Zinc 4% Serum (NZ) targets severe sebum production and skin texture issues. An Aloe Leaf Extract base replaces standard purified water for a more concentrated delivery. This update doubles the Niacinamide and quadruples the Zinc concentration compared to the previous 10% formula.
