1.📸My Pores Called, They’re Fine

Day one I slapped this on and immediately texted my esthetician “I think I’m in love.” It’s water. But it’s *not* water.

Every toner claims to tighten pores, but most just leave you tight and angry. This one actually plumped my skin so much my fine lines looked confused.

2.🧴What Even Is This Stuff

It’s Numbuzin No.3 Super Glowing Essence Toner — a milky, cloudy liquid you pat on after cleansing. $22 for 200ml. The claim: refine texture and shrink pores without stripping your barrier.

Thick enough to layer, thin enough not to feel like glue.

2

Fermented AF

Contains 33% rice ferment filtrate. Smells like sake, not flowers.

3

No Sticky Finish

Absorbs in 10 seconds flat. Makeup sits on top like a dream.

3.📝Ingredients That Actually Work

Hero here is rice ferment filtrate — it’s exfoliating but gentle, like a soft scrub you don’t rinse off. Niacinamide brightens, panthenol calms, and there’s no alcohol to burn your face off.

  • Rice Ferment Filtrate: Gentle exfoliation + glow without irritation
  • Niacinamide: Shrinks pores by controlling oil production
  • Panthenol: Soothes so you can use this daily without redness
  • Betaine: Locks in moisture so your skin doesn’t shrivel

4.🔬30 Days of Slapping

First splash: feels like water but thicker — almost milky. Absorbs in seconds. Zero stickiness. My skin felt bouncy, not tight.

Week 2 I noticed my nose pores looked… smaller? Not vanished, but definitely less “I’m a strawberry” energy. Week 3 my skin started reflecting light in a way that made me stop wearing highlighter.

💡

One Thing: Don’t use a cotton pad. Pour directly into palms, pat 2-3 layers. The friction of cotton ruins the whole point.

5.The Real Talk Results

My pores are visibly smaller — probably 20-30% — and my texture is smoother. But I still get breakouts before my period. It’s not magic, it’s maintenance.

Buy if
You have combo/oily skin and want glow without grease
⏭️

Skip if
You hate fermented smells or have fungal acne (ferments can aggravate it)
💰

Worth it?
$22 for 200ml that lasts 2 months? Yes. Skip the $60 exfoliating toners.
