1.🔍Pore Police Report

My nose looked like a strawberry. All those little dots.

The promise? Not to shrink pores — that’s impossible — but to make them look less obvious. A subtle but crucial difference.

2.🧪The Viral Bottle

It’s a $6 serum from The Ordinary. The claim: visibly reduce blemishes and congestion. For the price, I had to try.

1

Niacinamide 10%

A mega-dose of the pore-refining vitamin.

2

Zinc 1%

To mop up excess oil without total desertification.

3

The Price

Less than my morning latte.

3.🤔What’s In The Juice

It’s a brutally simple formula. Niacinamide is the star — it regulates oil and calms inflammation. Zinc is the backup singer for shine control.

  • Niacinamide: regulates sebum, calms redness
  • Zinc PCA: manages oil
  • Tamarinus Indica Seed Gum: the slip agent
  • Aqua: water, obviously

4.The Feel Test

Texture is slick — like slightly sticky water. Absorbs in 15 seconds flat. Leaves a faint, tight film.

Week 2 surprise: my T-zone was less greasy by noon. But if I used too much? It pilled under my moisturizer like eraser shreddings.

One Thing: Use ONE drop per cheek, one for the forehead. Pat, don’t rub. More is not better here.
