10% Niacinamide Booster
across 5 reviews
3.5/5
divided
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.
— best for: People new to niacinamide who have visibly enlarged pores or oily skin and are willing to introduce it gradually — mixing it with another product or using it once daily — are most likely to see a meaningful improvement.

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

This is such a wonderful product that I never knew I had needed in my skincare routine. I love to put this along with my moisturizer and sometimes even a light base serum. This has been helping to make my skin look much more brighter and even much more smoother. Shown in the before and after pics you can noticeably see I have some acne bumps and even some dark spots from recent acne that went away YesiiS · sephora.com
