About
What it is.
This cream-format booster in Paula's Choice's lineup pairs azelaic acid with salicylic acid (BHA) to target uneven tone, post-acne marks, and visible redness, backed by brightening botanicals. It's built to layer: apply after cleansing, toning, and exfoliating, then wear alone or mix into a serum, another booster, or a night moisturizer. Daytime use calls for sunscreen on top.
It fits people newly exploring niacinamide-adjacent actives who have visibly enlarged pores or oily, congested skin, and who are comfortable easing in slowly rather than layering it into an already-packed active routine. It suits anyone wanting a single cream to address tone and texture without building a multi-step regimen. It's a poor match for those already running several niacinamide products, or for reactive, rosacea-prone skin that doesn't tolerate acids well.
The verdict
This 10% niacinamide booster ranks second among niacinamide serums and delivers visible pore and oil-control benefits for users willing to introduce it gradually, but its potency risks irritation when used aggressively, and results remain modest rather than transformative.

AI summary of 5 reviews · as of Jun 2026
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.
What they 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
- Visible pore and oil-control results reported within a few weeks when used correctly
- Formulated without problematic ingredients; fits easily into most evidence-based routines
What they knock
- 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
- Paula's Choice claims visible results within a few days, which reviewers found overstated

How it holds up — after the dust settles
The booster delivers modest, real pore reduction over weeks but only if used conservatively — daily straight application at full strength proved counterproductive for at least one long-term tester.
Frequency of use
At launch
Twice-daily application as directed seemed reasonable and thorough.
After months
Twice-daily use on its own caused visible redness and irritation; once daily or mixed with another serum proved far more tolerable and effective over time.
Pore reduction
At launch
Early weeks showed promising, faster-than-expected improvement in pore size.
After months
Results plateaued or disappointed for reviewers already using niacinamide in other products; meaningful improvement was confirmed only for those who were niacinamide-naive or used the booster conservatively.
Irritation risk
At launch
The 10% concentration with soothing supporting ingredients seemed well-handled at first.
After months
Extended solo use at full concentration caused sustained redness for one tester, suggesting the 10% level is a genuine long-term concern rather than a brief adjustment phase.

Frequently asked
What buyers want to know.
What does Paula's Choice 10% niacinamide booster do?
It targets enlarged pores and oily skin. Reviewers report visible pore and oil-control results within a few weeks when used correctly, though the results are gradual rather than dramatic.
Is it safe to use 10% niacinamide everyday?
The 10% concentration can cause redness and irritation, especially when used undiluted twice daily as the label permits. Reviewers and a dermatologist suggest once-daily use in the evening as a safer approach to avoid irritation.
Who is this product best for?
People new to niacinamide who have visibly enlarged pores or oily skin and are willing to introduce it gradually—by mixing it with another product or using it once daily—are most likely to see meaningful improvement. It is not suited for anyone already using multiple niacinamide products, those with rosacea or reactiv…
What is the texture and packaging like?
It has a watery, lightweight texture that absorbs quickly and layers well under other products. A glass dropper protects the formula from light and dispenses cleanly.
Why do reviewers disagree on the results?
Reviewers report starkly opposite outcomes with the same product: one saw clear pore-shrinking results and called it a holy-grail product, while another saw skin look more irritated and porous after 30 days of daily use. Results vary considerably depending on how the product is applied and individual skin tolerance to…
What are the main drawbacks?
The small bottle runs out relatively quickly given the recommended dose. Results are modest and incremental, not transformative. If you already layer niacinamide elsewhere in your routine, this product may add little additional benefit.
