1.📅One Month, One Bottle

My forehead was a grease slick by noon. I was desperate.

This serum is everywhere — I had to know if it was all hype.

2.🔍The Viral Basics

It’s a $6 serum from The Ordinary. Claims to minimize pores and reduce shine. For that price, why not?

1

Texture

Watery, slightly sticky gel.

2

Scent

None. Smells like a lab (in a good way).

3

Packaging

Tiny glass dropper bottle — you’ll use it up fast.

3.📈What’s Actually In It

It’s a two-ingredient powerhouse. No frills, no filler. They do the heavy lifting.

  • Niacinamide 10%: Fights inflammation, regulates oil production
  • Zinc 1%: Helps control sebum, has astringent properties
  • Tamarinind Seed Extract: A natural polymer for slip
  • Carrageenan: Thickens the formula slightly

4.🤔The Real Test

Applies like water — absorbs in 15 seconds. Leaves a faint, tight film. Not a silky finish.

Week 2: My skin purged. Tiny whiteheads around my chin. Annoying, but it passed. Unexpected observation? It dried out a dry patch on my cheek I didn’t know I had.

💡

One Thing: Use only 3 drops for your whole face. More is not better — it will pill like crazy.

5.💡The Honest Results

Oil control? Legit. I now blot at 3 PM, not 11 AM. Pores? They look cleaner, but not magically “shrunk.” My foundation doesn’t slide off my nose. That’s a win.
