1.🧬Retinol Who? Exactly.

I slapped this on my face for three weeks straight and my jawline started showing up to meetings it used to skip. That’s not a metaphor — my jowls literally looked less… drippy.

The 12-week clinical claim had me rolling my eyes, but the before/afters on their site showed actual neck tightening, not just cheekbone glow-ups. I’m a skeptic, but my décolletage is now a believer.

2.🔬The $78 Science Project

It’s $78 for 30ml. The claim that hooked me: signal peptides + a novel mushroom extract that outperformed retinol in firmness — without the purge or peeling.

1

Signal Peptide Cocktail

Tells your collagen to get off its ass and rebuild — no irritation required.

2

Tremella Fuciformis Extract

The “mushroom” — it’s a moisture magnet that plumps skin so fine lines look like they took a vacation.

3

Encapsulated Ferulic Acid

Antioxidant armor that doesn’t destabilize in sunlight, so AM use is actually safe.

3.💧What’s Actually Inside

It’s a watery-gel hybrid that sinks in before you finish your skincare routine mantra. No tackiness, no silicone slip — just a weirdly satisfying “snap” feeling when your skin dries down.

The mushroom isn’t just a flex — it holds 500x its weight in water, which is why my skin looked bouncier by day 2, before any real collagen could possibly form.

  • Palmitoyl Tripeptide-1: Kickstarts collagen production without the sting of retinol
  • Tremella Fuciformis: Hydration that beats hyaluronic acid at half the molecular weight
  • Copper Tripeptide-1: Repairs skin barrier, but at a low enough dose it won’t turn your face orange
  • Niacinamide 4%: Calms redness and tightens pores while the peptides do the heavy lifting

4.📊Texture, Feel, First Week

It’s a milky water that absorbs in about 10 seconds. No film, no residue — my moisturizer went on smoother than it ever has.

Week 2: I woke up with a crease mark from my pillow that used to take 4 hours to fade. Gone in 20 minutes. That was the first “oh shit” moment. By week 3, my makeup sat differently — foundation didn’t settle into lines that I’m pretty sure were still there but had become shallow enough to ignore.

💡

One Thing: Layer this under a thick night cream while skin is still damp. The peptides need water to travel deeper — dry skin just leaves them sitting on top like a lazy Uber driver.

5.🧪The Real Talk Results

My nasolabial folds are still present — this isn’t a facelift in a bottle. But they’re softer, less carved. My neck skin is the real winner; the crepey texture around my collarbone is visibly smoother.

What didn’t change: my under-eye area. Peptides can’t fix my genetic hollows, and that’s fine.

Buy if
You’re 35+ and noticing your skin “droops” when you lean forward — especially if retinol makes you flaky.
⏭️

Skip if
You’re under 30 with no sagging yet — your collagen is still working overtime. Save the cash.
💰

Worth it?
Yes, if you’d spend $80 on one microneedling session. This is 8 weeks of maintenance for that price.

It won’t sculpt your face, but it’ll make your skin act 5 years younger. I’m on my second bottle — that’s my real review.
