1.🔬Pore Shrinkage, Debunked

Let’s be real. You can’t physically shrink a pore.

They don’t have muscles. But you can make them *look* smaller — and that’s where this serum from The Ordinary comes in. The goal is less “tiny hole” and more “clean, tight-looking tube.”

2.❓The Viral Promise

It’s $6.80. The claim? Visibly reduce blemishes and congestion for clearer, more even skin. I tried it because my nose looked like a strawberry.

2

Zinc 1%

Tackles excess oil without turning you into a desert.

3

The Price

Cheaper than your morning latte.

3.🧪What’s In The Bottle

It’s a two-ingredient show. Niacinamide (Vitamin B3) regulates oil and smoothes texture. Zinc PCA helps control shine.

  • Niacinamide: Regulates sebum, calms inflammation
  • Zinc PCA: Mattifies, aids healing
  • Tamarinus Indica Seed Gum: The slimy texture base
  • Pentylene Glycol: Lightweight hydration

4.👁️The Sticky Truth

Texture is weird — like slightly sticky water. Absorbs in 15 seconds if your skin is bone-dry. Wait for it to sink in before anything else.

Week 3: My t-zone was less of an oil slick by 2 PM. Unexpected win? My foundation stopped sliding off my nose.

💡

One Thing: Apply to COMPLETELY dry skin. Damp skin makes it pill like crazy.

5.📉Did It Actually Work?

Pores look tighter because they’re cleaner and less stretched with oil. Actual size? Unchanged. But the visual difference is legit.

6.✅The Final Word

It’s not magic. It’s science. Manages oil so pores appear minimized — and for the price, it’s a no-brainer experiment.
