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.
Multiple users note this formula does not ball up under other products or makeup, unlike some competing niacinamide serums.
Users with dry or combination skin report this feels more hydrating than pure niacinamide serums with zinc, likely due to the squalane, HA, and lack of zinc.
The squeeze bottle with press-down cap makes it difficult to control how much product dispenses. Some users report buildup around the opening.
Consistent feedback about reduced pore appearance within 2-4 weeks of daily use.
Which Should You Buy?
The Inkey List Niacinamide Oil Control Serum offers great value at a lower price point. COSRX The Niacinamide 15 Serum may be worth the premium if you want Niacinamide (15%).
