Compare Products: Niacinamide Oil Control Serum vs Niacinamide 10% + Zinc 1% Serum
Ingredient Analysis
The Inkey List Niacinamide Oil Control Serum is a richer, more hydration-focused serum with multiple skin-replenishing ingredients. The Ordinary Niacinamide 10% + Zinc 1% Serum is a leaner, pore- and oil-control formula built around niacinamide and zinc. The better choice depends on your skin type and primary concern.
The Inkey List Niacinamide Oil Control Serum includes hyaluronic acid, panthenol, glycerin, squalane, and phospholipids. The Ordinary Niacinamide 10% + Zinc 1% Serum offers only basic humectants.
Zinc PCA directly regulates sebum. The Inkey List Niacinamide Oil Control Serum has no comparable oil-control ingredient.
Phospholipids, squalane, soybean oil, and allantoin actively rebuild and protect the skin barrier. The Ordinary Niacinamide 10% + Zinc 1% Serum lacks these.
The Ordinary Niacinamide 10% + Zinc 1% Serum uses two preservatives (phenoxyethanol and chlorphenesin together), which raises irritation risk slightly more than The Inkey List Niacinamide Oil Control Serum's single preservative system.
The Ordinary Niacinamide 10% + Zinc 1% Serum has 11 ingredients versus The Inkey List Niacinamide Oil Control Serum's 24. Fewer ingredients means fewer variables for reactive skin to respond to.
- •Niacinamide concentration is unlisted in both products. Efficacy depends heavily on percentage used.
- •Zinc PCA concentration in The Ordinary Niacinamide 10% + Zinc 1% Serum is undisclosed; its sebum-control effect scales with dose.
- •The Inkey List Niacinamide Oil Control Serum lists hyaluronic acid near the end of the list, suggesting a low concentration.
- •Chlorphenesin in The Ordinary Niacinamide 10% + Zinc 1% Serum is safe at approved levels but may irritate very sensitive skin at higher doses.
- •The identified name for The Ordinary Niacinamide 10% + Zinc 1% Serum is an inference based on the INCI pattern; it has not been confirmed.
- •Soybean oil in The Inkey List Niacinamide Oil Control Serum may not suit skin prone to comedones, though evidence is mixed.

User Feedback Patterns
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.
Many users with oily skin report significant oil control and fewer breakouts. High repurchase rate in this demographic.
Commonly reported issue. Users recommend applying to damp skin or mixing with a hydrating serum to improve layering.
The formula can feel sticky, especially if too much is applied. Most users adapt application technique over time.
Some users report initial breakouts. Unclear whether this is purging, sensitivity, or coincidence. Most who push through report improvement.
