Does Niacinamide Really Reduce Pores? We Tested The Ordinary Serum

Myth Busted
This viral serum promises to shrink pores, but does the science back up the hype?
Expert Analysis · Honest Reviews · Real Results
1.🔬The Pore Shrinkage Myth

No serum can physically shrink your pores. That’s the first thing my derm friend said when I showed her the bottle.

But they can look smaller — and that’s the magic trick this $6 serum attempts.

2.❌The Viral Tube

It’s a 1-oz dropper bottle from The Ordinary. Claims to minimize pores, reduce shine, and clear congestion. For the price, I had to test the hype.

1

Texture

A clear, slightly sticky serum.

2

Scent

Absolutely none — it smells like a lab.

3

Price

$6.20. Less than my oat milk latte.

3.🧪Science, Not Magic

10% Niacinamide is the star. It regulates oil and calms inflammation. 1% Zinc pulls double duty on sebum control.

  • Niacinamide (10%): Regulates oil & improves skin barrier
  • Zinc PCA (1%): Mattifies & reduces shine
  • Hyaluronic Acid Crosspolymer: Lightweight hydration
  • Tamrindus Indica Seed Gum: That weird sticky texture
4.🔍The Sticky Truth

Applies like a thin gel — absorbs in 20 seconds but leaves a faint, tacky film. Not silky. You feel it.

By week two, my T-zone was noticeably less greasy by noon. Unexpected downside? It pills like crazy under moisturizer if you don’t let it fully dry.

💡

One Thing: Apply to bone-dry skin. Wait a full 90 seconds before your next layer. Non-negotiable.
5.✅The Real Results

Pores didn’t vanish. But with less oil filling them, they appeared cleaner and less obvious. My foundation stayed put longer. Zero effect on deep blackheads.

✅

Buy if
You have oily, shiny skin and want a budget oil-regulator.
⏭️

Skip if

💰

Worth it?
For $6, it’s a brilliant intro to niacinamide. Manage expectations.
6.💡Final Call

It’s a brilliant, no-frills oil controller — not a pore-minimizing miracle. For the price, it delivers one specific job well.

7.5/10
A sticky, effective budget buy for shine.
