Expert Analysis · Honest Reviews · Real Results
1.🧪Yeast Isn’t Just For Bread

This toner has 93% yeast ferment filtrate. That’s not a typo — it’s basically a fermented soup for your face.

The real flex? Fermentation breaks down ingredients into smaller particles. Your skin absorbs them faster — like pre-chewed food but way less gross.

2.🔬What’s In The Bottle

It’s a liquid toner, not thick like a cream. $22 for 150ml. The claim: one layer hydrates like three. I rolled my eyes — then tried it.

1

Yeast Ferment Filtrate

The star — packed with amino acids and vitamins that calm redness and strengthen your barrier.

2

Panthenol

Also known as vitamin B5. Soothes irritation fast — think of it as a chill pill for your face.

3

Betaine

A moisture magnet. Pulls water into your skin without feeling sticky — weirdly satisfying.

3.💧Ingredient Lowdown

No frills here. Four real workers, no filler nonsense. The ferment filtrate does the heavy lifting — it’s not just buzzword bait.

  • Yeast Ferment Filtrate: Boosts barrier repair and hydration in one swipe
  • Panthenol: Calms inflammation — great for post-acne redness
  • Betaine: Locks in moisture without clogging pores
  • Sodium Hyaluronate: Hydrates deeper than regular hyaluronic acid

4.🧴Texture & Real Talk

Water-thin. Smells faintly like sourdough — not gross, just unexpected. Absorbs in 10 seconds flat. No tacky residue.

Week 2: My skin stopped drinking moisturizer like it was dying. One layer of this + a basic cream = done. Surprise: didn’t break me out (fermented stuff usually does).

💡

One Thing: Pat it in with damp hands — don’t use a cotton pad. You waste product and lose the ferment goodness.

5.📊Did It Actually Work?

Less redness around my nose. Skin feels bouncier — like a fresh grape. But it didn’t fix my dry patches overnight. That’s a lie brands sell.

💰

Worth it?
$22 for 3 months of use. Yes — cheaper than buying three separate hydrating products.
