10% Niacinamide Face Serum with 2% Zinc PCA - 50ml
The same 10% Niacinamide + 2% Zinc PCA formula as the 30ml SKU, offered in a larger 50ml size for sustained routine use. Identical INCI: Niacinamide at position 2 (confirmed 10%), Zinc PCA at position 6 (confirmed 2%), Dimethyl Isosorbide as penetration enhancer, Algin as natural thickener. The dual preservative system (Phenoxyethanol, Sodium Benzoate, Potassium Sorbate, Ethylhexylglycerin) remains the same.
