What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Glass dropper packaging protects the formula from light and dispenses cleanly
- Watery, lightweight texture absorbs quickly and layers well under other products
- Niacinamide at 10% is supported by soothing co-ingredients that help offset potential irritation
Reviewers push back
- 10% concentration can cause redness and irritation, especially when used undiluted twice daily as the label permits
- Results are modest and incremental — not a dramatic transformation, and users already layering niacinamide elsewhere may see little added benefit
- Small bottle volume means the product runs out relatively quickly given the recommended dose
A well-formulated niacinamide booster that delivers real pore and oil-control benefits for many users, but the 10% concentration can irritate skin when used aggressively, and results vary considerably depending on how it is applied.
One reviewer saw clear pore-shrinking results within two weeks and called it a holy-grail product; another saw skin look more irritated and porous after 30 days of daily use — the same product, starkly opposite outcomes
