1.🌿Big Pharma to Bathtub

So my feed served me this brand founder who quit her Pfizer job to ferment botanicals in a Brooklyn apartment. I rolled my eyes so hard they almost stuck.

Then the mask sold out in 48 hours. Twice. And my dry-ass winter skin was begging for something stupidly rich, so I caved at 2am. Classic.

2.🏭The Price of Sleep

It’s $58 for 1.7oz. Not cheap, but cheaper than Tatcha’s $52 for half the size. The pitch: “overnight recovery without the slug life.” That got me.

1

Fermented Complex

It’s alive. Like, actually fermented in small batches — smells faintly sour, not like a perfume counter.

2

Zero Grease

Somehow sinks in fully in 4 minutes. No pillow-slip sacrifice.

3

Squalane Base

Lightweight but seals everything in. My stupid sensitive skin didn’t react once.

3.🧪Brooklyn Science

The hero is a fermented yeast lysate that basically teaches your skin to hold water overnight. It’s the kind of smart-nerd ingredient Big Pharma would patent — she just did it in a kitchen.

  • Fermented Yeast Lysate: strengthens moisture barrier while you drool
  • Squalane: locks in hydration without suffocating pores
  • Centella Asiatica: calms the angry redness I wake up with
  • Niacinamide: fades my dark spots from picking at stress breakouts

4.Pillowcase Test

Texture is a weird hybrid — like gelato that’s half-melted. Cool on contact, then vanishes into a soft, matte film. Not sticky. Not greasy. Just… gone.

Week 3: I woke up with less puffiness under my eyes and my forehead lines looked softer. But my chin still peeled a bit — it’s not a miracle worker for exfoliation.

💡

One Thing: Apply it 20 minutes before bed on damp skin. It locks in your serum better and you won’t waste product.

5.📦The Reckoning

My skin looked plumper by day 4. Redness around my nose? Gone by day 10. But it didn’t fix my flaky patches completely, and I still needed a separate exfoliant.

Buy if
You’re dry/dehydrated, hate greasy night creams, and want visible plumpness by morning
⏭️

Skip if
You need heavy exfoliation or have super oily skin — this won’t clear your pores
💰

Worth it?
Yes for the price. Tatcha’s $52 mask does less and feels more perfumey.

6.💤Final Call

It’s better than Tatcha. There, I said it. More effective, less fussy, and the founder actually knows her microbiology.

8.7/10
Serious overnight hydration without the grease trap
