You see 10% niacinamide and think “pores, begone.” But for sensitive skin? That number is a dare, not a promise.
The real issue isn’t the percentage — it’s whether the formula knows how to hold your hand through the burn. Most don’t. This one tries.
It’s $28 for 30ml of Numbuzin‘s gold-label serum. The claim: visible pore refinement in 4 weeks. I called bullshit. Then I tried it.
5% Panthenol
The buffer. Stops the niacinamide from nuking your moisture barrier like a cheap peel.
Fermented Yeast Complex
Not just filler — actually calms the redness high-strength niacinamide loves to trigger.
No Fragrance
Thank god. One spritz of perfume in a serum and I’m out.

10% niacinamide is the headline, but the supporting cast does the heavy lifting. Without them, your face would throw a tantrum.
- Niacinamide 10%: Shrinks pores + controls oil — but burns if alone
- Panthenol 5%: Soothes irritation so you don’t peel like a snake
- Madecassoside: Repairs barrier damage in real time
- Sodium Hyaluronate: Keeps hydration locked so the niacinamide doesn’t dry you out

It’s a watery gel — slips on like water, absorbs in 12 seconds flat. No sticky residue, no film. First day I felt a tingle. Not the good kind.
Week two: the tingle disappeared. My pores looked… smaller? Not gone — but like they’d been gently scolded into submission. Unexpected win: my nose stopped shining by noon.

Pores visibly tighter. Sebum production down 40%. But hyperpigmentation? Barely budged. It’s a pore serum, not a spot eraser.

It’s not a miracle, but it’s honest work. If your skin can handle the percentage, you’ll see real pore tightening in 3 weeks. If it can’t? You’ll know by day two.
