1.🔍The Shine Tamer

My forehead was a lighthouse. You could see it from space.

This serum promised to fix that without turning me into a flaky desert — a rare feat.

2.💡The Basics

It’s a water-based serum from The Ordinary. Under $10. The “cult-favorite” hype made me skeptical, but the price made it a low-risk experiment.

1

Niacinamide 10%

A high dose of the pore-refining, oil-regulating vitamin.

2

Zinc 1%

Adds a layer of sebum control and calms inflammation.

3

No Nonsense

The bottle has zero aesthetic appeal — it’s pure function.

3.⚖️What’s Inside

It’s a short, focused list. The two stars work together: niacinamide tells your pores to chill on oil production, zinc helps mop up the excess that’s already there.

  • Niacinamide: regulates sebum & minimizes pores
  • Zinc PCA: absorbs oil, reduces shine
  • Tamarinus Indica Seed Gum: gives it that slick, slightly sticky texture
  • Aqua (Water): the base — it’s very simple

4.📈Skin Feel

Texture is weird — like slightly sticky water. Absorbs in 8 seconds flat. Leaves a faint, tight film. Not moisturizing at all.

By week two, my midday blotting paper habit was cut in half. The surprise? It made my foundation sit better — no sliding off by 10 AM.

💡

One Thing: Apply to bone-dry skin. If your face is even slightly damp, it pills into little gray eraser shreds.
5.🚫The Real Deal

Shine is controlled, not eliminated. Pores look a bit tighter. Did it cure my oiliness? No. But it manages it like a competent manager — things run smoother.
