Compare Products: Clinical Niacinamide 20% Treatment vs Niacinamide Oil Control Serum
Ingredient Analysis
Paula's Choice Clinical Niacinamide 20% Treatment leads on brightening actives, packing niacinamide, ascorbyl glucoside, and acetyl glucosamine together. The Inkey List Niacinamide Oil Control Serum focuses on barrier repair and deep hydration via squalane, phospholipids, and hyaluronic acid. Choose based on your primary skin goal.
Paula's Choice Clinical Niacinamide 20% Treatment combines ascorbyl glucoside, acetyl glucosamine, licorice extract, and EGCG. The Inkey List Niacinamide Oil Control Serum has no dedicated brightening actives beyond niacinamide.
Squalane, phospholipids, hyaluronic acid, and plant sterols give The Inkey List Niacinamide Oil Control Serum a clear edge for deep moisture and lipid barrier repair.
Paula's Choice Clinical Niacinamide 20% Treatment includes EGCG, green tea leaf extract, purslane, meadowsweet, and ascorbyl glucoside. The Inkey List Niacinamide Oil Control Serum offers minimal antioxidant support.
Paula's Choice Clinical Niacinamide 20% Treatment has fewer surfactants and emulsifiers. The Inkey List Niacinamide Oil Control Serum adds polysorbate 60 and sorbitan isostearate, which can sensitize compromised skin.
Both use xanthan gum as a primary thickener. The Inkey List Niacinamide Oil Control Serum adds an acrylate copolymer for a silkier gel feel; Paula's Choice Clinical Niacinamide 20% Treatment uses pullulan for a smoothing film effect.
- •Niacinamide concentration is undisclosed in both products; efficacy depends heavily on whether it reaches the 2-5% range shown in studies.
- •Ascorbyl glucoside in Paula's Choice Clinical Niacinamide 20% Treatment is a stable but less potent vitamin C form compared to L-ascorbic acid; conversion rate in skin is debated.
- •Hyaluronic acid appears near the end of The Inkey List Niacinamide Oil Control Serum's list, suggesting a low concentration that may limit its standalone hydrating impact.
- •Exact phospholipid and glycolipid concentrations in The Inkey List Niacinamide Oil Control Serum are unknown; barrier benefits may be modest at trace levels.
- •Leuconostoc/Radish Root Ferment Filtrate is listed late in The Inkey List Niacinamide Oil Control Serum, so its microbiome or preservative effect may be minimal.
- •No pH values are disclosed for either product, which matters for active ingredient stability, especially ascorbyl glucoside.

User Feedback Patterns
Users who found the 10% booster insufficient often report better results with this formula, particularly for aging-related pore concerns and textural issues.
The gel texture feels slightly oily to some users before it dries down. Some report a tacky feel or that it takes time to absorb. Most find it works well under moisturizer.
Some users report sensitivity, flushing, or irritation — especially if used daily from the start. Several reviewers recommend using every other day initially or finding 10% sufficient.
Like the 10% booster, results are typically seen over weeks of consistent use rather than immediately. Some users report noticeable improvement within 1-2 weeks; others need longer.
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. Paula's Choice Clinical Niacinamide 20% Treatment may be worth the premium if you want Niacinamide (20%).
