User Feedback Patterns

Paula's Choice
More effective than 10% for stubborn concerns

Users who found the 10% booster insufficient often report better results with this formula, particularly for aging-related pore concerns and textural issues.

Texture and feel

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.

Potential irritation at high concentration

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.

Gradual, cumulative results

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.

The Inkey List
No pilling

Multiple users note this formula does not ball up under other products or makeup, unlike some competing niacinamide serums.

More hydrating than expected

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.

Packaging frustrations

The squeeze bottle with press-down cap makes it difficult to control how much product dispenses. Some users report buildup around the opening.

Visible pore improvement

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%).
