1.📝My Pores Said Thank You

I slathered this viral 10% niacinamide goo on my face every single morning for a month — no days off, even when I was hungover and lazy.

The real reason this matters? My T-zone has been an oil slick since 2009, and every “pore-refining” product I’ve tried has either burned or lied. This one didn’t do either.

2.🧪What You’re Actually Buying

It’s a 30ml dropper bottle, roughly $28, and the claim that got me was “visible pore refinement in 14 days.” Bold. I called bullshit. Then I tested it.

1

10% Pure Niacinamide

Zero fluff — this is a clinical-strength dose, not the 2% you find in moisturizers.

2

Zinc PCA Complex

The sidekick that actually calms my angry redness instead of just masking it.

3

No Fragrance, No Dyes

Smells like nothing. Absorbs in about 20 seconds. Doesn’t pill under my SPF.

3.📸What’s Really Inside

It’s a stripped-back formula — no 40-ingredient flex, just the stuff that works. The texture is a watery gel that disappears before I finish blinking.

  • Niacinamide: Shrinks the look of pores by regulating oil production
  • Zinc PCA: Anti-inflammatory that nukes active breakouts
  • Hyaluronic Acid: Pulls in water so the niacinamide doesn’t dry you out
  • Allantoin: The quiet hero that prevents irritation

4.🌅The 30-Day Grind

Day 1: Feels like water. Day 5: My chin broke out — I almost quit. Day 12: The purge cleared and my skin looked… calm?

The surprise? By week three, my makeup stayed matte until 3pm instead of sliding off by noon. I didn’t expect a serum to fix my foundation game.

💡

One Thing: Apply this on damp skin, right after cleansing. Dry skin makes it sit on top and feel tacky — damp skin pulls it in fast.

5.🔍The Honest Receipts

My nose pores are visibly smaller — not gone, not photoshopped, but smaller. The oil slick is now a light sheen. Blackheads? Still there, but less… angry.

Worth it?
For $28, yes. It’s half the price of the Ordinary’s cult version but cosmetically more elegant.

I’d rebuy this tomorrow. It’s not magic, but it’s the closest thing I’ve found to a pore-minimizing oil-control cheat code.
