User Feedback Patterns

La Roche Posay
Effective for post-acne marks

Users frequently report fading of post-inflammatory hyperpigmentation from acne. Often noted as more effective than previous vitamin C serums.

Gentle on sensitive skin

Despite fragrance, many sensitive skin users report no irritation. Users with rosacea have noted tolerance.

Gradual results

Users report seeing changes over weeks to months. Not overnight results, but consistent improvement with regular use.

Texture praise

Lightweight serum absorbs quickly without greasiness. Layers well under sunscreen and makeup.

Mixed expectations

Some users with stubborn melasma or very dark spots report only modest improvement. Works better on newer or less severe pigmentation.

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. La Roche Posay Mela B3 Serum may be worth the premium if you want Niacinamide (10%).
