So I got obsessed with this Pestle & Mortar thing because it’s not another hyped-up K-beauty dupe. It’s Irish. And they treat skincare like a pharmaceutical contract — not a trend. The founder’s a pharmacist. That changes everything.
The formula feels *sober*. No fragrance. No color. No bullshit. Just niacinamide at a concentration that actually works (5%), paired with zinc to keep oil in check. It’s the kind of serum your dermatologist would design if they had a lab and zero interest in Instagram.
🌟 **Three Things It Does**
It’s €38 for 30ml. Mid-range. The claim that got me: “reduces pore appearance in 2 weeks.” I laughed. Then I measured.
Pore Minimization
After 10 days, my nose pores looked like they’d been on a diet — smaller, less textured.
Oil Regulation
My T-zone stopped producing enough grease to fry an egg by 3pm.
Texture Smoothing
Those tiny bumps around my chin? Gone. Flat. Like they never existed.

🔍 **What’s Actually Inside**
It’s not a cocktail party in a bottle. Three heroes, one job.
- Niacinamide (5%): Brightens + strengthens barrier — the boring workhorse
- Zinc PCA: Calms oil production without stripping
- Hyaluronic Acid: Plumps without stickiness — barely any, just enough
No retinol. No vitamin C. It’s a *supporting actor* serum, not the lead. That’s the point.
📊 **Texture + Real Talk**
It’s watery. Like, *runs-down-your-wrist* watery. Absorbs in 8 seconds flat. No tacky film. No pilling under moisturizer.
Week 2: I woke up and my skin looked… rested? Not glowing, not glass-skin, just *calm*. The kind of calm you get after a solid night’s sleep, not a 10-step routine. Unexpected win: it didn’t break me out. Most niacinamide serums give me tiny whiteheads. This one didn’t.
📖 **The Honest Results**
My pores are visually smaller — not gone, but noticeably less aggressive. My redness is down maybe 30%. Oil production cut by half. But here’s the thing: if you’re expecting a glow bomb, you’ll be disappointed. This is *maintenance*, not transformation.
🌟 **Final Call**
It’s the most boring serum I’ve ever loved. And that’s exactly why it works.
