Everyone’s slapping “fermented” on a bottle lately. But Numbuzin actually did the homework. Their No.3 serum uses probiotics that match your skin’s natural microbiome — not random yeast extract.
Most brands just ferment one ingredient and call it a day. This one uses a 7-step fermentation process that breaks everything down into smaller molecules. Your skin absorbs it in under 15 seconds. No waiting around.
It’s $28 for 50ml. Mid-range price, but the dropper bottle feels heavier than it should. The claim that got me? “Skin-identical probiotics.” They’re using the same strains that live on healthy skin naturally.
Lactobacillus Ferment
Not the yogurt kind — a specific skin strain that boosts ceramide production.
Galactomyces Ferment Filtrate
Lighter than SK-II’s version. Less likely to break you out.
Bifida Ferment Lysate
The one Estée Lauder charges $100+ for. Repairs UV damage over time.
No essential oils. No fragrance. Just fermented actives and humectants. The hero is their proprietary 7X Fermented Complex — they ferment seven different botanical extracts together, not separately. That’s weirdly smart.
- 7X Fermented Complex: 7 botanics fermented together = smaller molecules, deeper absorption
- Niacinamide 4%: Brightens without the sting of higher percentages
- Panthenol: Calms any fermentation-related flush in 2 minutes
- Sodium Hyaluronate: Low molecular weight — actually penetrates, doesn’t sit on top
Watery-gel. Slightly tacky for 10 seconds, then disappears completely. No film, no stickiness. I layered it under sunscreen and my makeup didn’t pill — miracle.
Week 3: My skin looked… healthy. Not glass-skin dramatic, but that dull “I stayed up too late” look vanished. Unexpected win: my nose pores looked smaller. Did not expect that from a glow serum.
After 4 weeks: skin looks bouncier, redness around my nose calmed down, and my moisturizer actually does its job now. Didn’t fix my dark spots. Didn’t peel my face off.
It’s the glow serum for people who can’t tolerate glow serums. Fermentation done right — no irritation, just slow, steady brightness.
