1.🔍The Pore Lie

My bathroom mirror is a liar. It shows every single pore. So I tried the internet’s favorite fix.

The truth? Pores don’t open and close. They can’t shrink. The goal is just to make them *look* smaller.

2.🧪The Viral Serum

It’s The Ordinary‘s Niacinamide 10% + Zinc 1%. $5.90. The claim? Visibly reduce blemishes and congestion. For that price, I had to test the hype.

1

Texture

Water-based serum — feels like slightly sticky water.

2

Scent

Zero fragrance. Smells like… a lab. In a good way.

3

Packaging

The dropper is functional. But it’s not Instagram-pretty — it’s science class.

3.What’s Actually In It

It’s a short, blunt list. Niacinamide is the star — it helps regulate oil and calm inflammation. Zinc is the sidekick for oil control.

  • Niacinamide 10%: Regulates sebum, calms redness
  • Zinc PCA 1%: Mattifies, controls oil
  • Tamrindus Indica Seed Gum: The texture agent
  • Pentylene Glycol: Hydration + preservation
4.The Sticky Truth

Applies like a thin gel. Absorbs in 15 seconds — but leaves a faint, tacky film. You feel it.

Week 2: My T-zone was noticeably less shiny by noon. The surprise? It pilled under my moisturizer like crazy. A real makeup nightmare.

💡

One Thing: Apply to *completely* dry skin. Wait a full 60 seconds before your next step. Cuts the pilling by 90%.
5.📊Did It Work?

After a month, my pores didn’t vanish. But the oil slick on my nose did. That means less gunk getting stuck — so pores *appear* cleaner and tighter. A solid B+ result.

Worth it?
For under $6? Absolutely. It’s a brilliant intro to niacinamide.
6.💡The Final Word

It’s not a pore-shrinking miracle. It’s an oil-blotting, clarity-boosting workhorse. Manages expectations — and shine.
