User Feedback Patterns
Users consistently report significant reduction in daytime oil and shine. Many describe it as the best niacinamide serum they have tried for sebum control.
Unlike some high-concentration serums, this absorbs quickly without tackiness or residue. Layers well under other products.
The 20ml size (vs. 30ml standard) is a common gripe, especially given the price point.
Users report visible pore improvement around the 3-4 week mark with consistent twice-daily use.
Users with very oily skin consistently report this as one of the most effective oil-control products they have tried. Many note all-day mattifying effect.
Despite the 20% concentration, most users report no irritation. However, patch testing is frequently mentioned as important for first-time users.
Users who found The Ordinary's 10% niacinamide too weak or pilling-prone often prefer this. The gel texture absorbs cleanly.
Some users report a white film if they apply too much. The brand addresses this: use less product and follow immediately with moisturizer.
Which Should You Buy?
The Inkey List SuperSolutions 20% Niacinamide Serum offers great value at a lower price point. COSRX The Niacinamide 15 Serum may be worth the premium if you want Niacinamide (15%).
