1.☀️Ditch the Blotting Papers

I watched a girl in Union Square blot her face four times in one block. Four. That’s not living — that’s damage control. Stop it.

Here’s the thing about summer shine: you can’t powder your way out of humidity. You need to stop the oil before it hits the surface. This serum does that — without making your skin feel like a chalkboard.

2.🧴What’s In The Tube

It’s Inkey List‘s Niacinamide Oil Control Serum. $10.99. They claim it visibly reduces shine in 28 days — I rolled my eyes, too.

1

2% Salicylic Acid

Clears pores so oil has nowhere to pool. Basic but effective.

2

Niacinamide at 5%

The sweet spot. Enough to regulate sebum, not so much it irritates.

3

Zinc PCA

The unsung hero. Dries down matte without that tight, fake feeling.

3.🌡️Actually, Read This

Most niacinamide serums are 10% — which is overkill and often causes purging. This one’s 5%, which is smarter. You don’t need to nuke your face to control oil.

  • Niacinamide 5%: Regulates oil production without stripping
  • Zinc PCA: Absorbs excess sebum on contact
  • Salicylic Acid 2%: Exfoliates inside the pore
  • Sodium Hyaluronate: Keeps hydration intact — yes, you still need moisture

4.💧The Texture Test

It’s a thin gel-liquid. Absorbs in 10 seconds flat. No residue. No pilling under sunscreen. I actually forgot I put it on — that’s the goal.

Week two: my T-zone stopped producing oil by noon. The surprise? My cheeks didn’t get dry. That never happens with oil-control products. They usually nuke everything.

💡

One Thing: Apply to damp skin right after washing. Dry skin soaks it up too fast and it doesn’t spread evenly. Damp = even coverage + no stickiness.

5.🔬The Honest Results

After 4 weeks: 60% less shine by 3pm. Pores look smaller — not gone, just less noticeable. Still get oily if I skip a day. Maintenance is real.

6.Final Call

This won’t make you matte forever — nothing will. But it’ll buy you 4-5 hours of not looking like a glazed donut. For $10, that’s a win.
