**To:** You
**Subject:** Dr. Different niacinamide — the 21% truth
—
Day 1: I put 21% niacinamide on my face and my skin did not freak out. That alone was a win.
Day 30: My nose looks like I finally stopped trying to deep-fry my pores from the inside. Oil production dialed down — not gone, just… quieter. Like it finally got the memo.
It’s $28 for 30ml. A Korean brand that decided 10% niacinamide was for amateurs. I bought it because I’m oily, clog-prone, and tired of blotting papers by noon.
21% Niacinamide
Highest concentration I’ve seen outside a lab. Not for sensitive skin — start slow or regret it.
Zinc PCA + NAG
They’re there to calm the irritation this high a dose could cause. It works — mostly.
No fragrance
Thank god. 21% is already a lot — don’t need perfume in there.
It’s not complex. Four things do the heavy lifting. The rest is just getting them on your face without breaking you out.
- Niacinamide 21%: shrinks pore appearance + cuts oil production visibly
- Zinc PCA: antimicrobial + sebum regulator — keeps acne in check
- NAG (N-Acetyl Glucosamine): mild exfoliation + fade dark spots slowly
- Hyaluronic Acid: stops the high niacinamide from drying you to a crisp
Thin, watery serum. Absorbs in 10 seconds — no sticky film, no pilling under moisturizer. Smells like nothing. That’s the dream.
Week 2: I got a weird dry patch near my jaw. Not a breakout — just tight skin. I was using it twice a day. Dropped to once. Problem solved. It’s strong — respect it.
Pores on my nose and cheeks look smaller — not gone, just less like craters. Oil production dropped about 40%. My midday shine became a late-afternoon glow. No new breakouts after week 1. Existing ones healed faster.
What didn’t change: my forehead pores. They’re stubborn. This didn’t erase them.
It’s not a miracle. It’s a very effective, very strong oil-control serum that does exactly what it says — if your skin can handle it. I’d buy it again.
