The Ordinary Niacinamide 10% + Zinc 1%
Water-based serum with 10% niacinamide for oil control, pore appearance, and tone evenness; 1% zinc PCA for sebum regulation. One of the highest cost-to-evidence-base ratios in OTC skincare. Explicit weakness: 10% can cause temporary flushing in niacin-sensitive users; contains silicone (dimethicone); niacinamide-vitamin-C interaction is largely theoretical but conservative users should layer them at separate times.
