Myth Busted
The internet says this $78 serum replaces your moisturizer — we put it to a 30-day test to see if the glow is real or just marketing.

1.🧴Moisturizer? Bold. Let’s Test It.

The internet claims this $78 serum can replace your moisturizer. That’s a big flex — so I stripped my routine down to just this for 30 days to see if my face would file a complaint.

My skin is combo-dehydrated — oily by 2 PM, flaky by Tuesday. If this didn’t hold up, you’d hear about it.

2.💸The $78 Gamble

It’s a lightweight serum that uses a “water-lock” system to mimic a cream’s occlusive layer. The claim: you can skip your moisturizer entirely.

1

Water-Lock Complex

Creates a breathable film that traps hydration without feeling like a slug mask.

2

Dewy Finish

Sits shiny for exactly 4 minutes, then sinks in to a natural glow — not a grease slick.

3

No Pilling

Layers under SPF without rolling off, which is rare for a gel-serum hybrid.

3.🔬What’s Actually Inside

It’s not just water and hope. The formula leans on humectants to pull moisture in, plus a lipid complex to keep it there. No heavy oils — that’s why it works for oily faces too.

  • Polyglutamic Acid: Holds 4x more water than hyaluronic acid on the skin’s surface
  • Squalane: A featherlight lipid that mimics your skin’s natural oils to repair the barrier
  • Panthenol: Calms redness and takes the angry edge off any tightness
  • Glycerin: The OG humectant that actually keeps moisture locked in the stratum corneum

4.🤲Texture & The Weird Week

It’s a thick-ish gel that melts into a watery veil. Absorbs in 10 seconds flat — no sticky residue, no waiting 20 minutes before sunscreen.

Week 2 got weird: my skin went through a “purging” phase where it felt slightly tacky for a day. Then it leveled out. By day 20, my forehead stopped flaking, and my T-zone wasn’t an oil slick by noon.

💡

One Thing: Apply this to damp skin — literally right after cleansing. It pulls the water in and makes the finish look glassy instead of matte.

5.📊The Glow Check

My skin looks rested, not wet. The flaky patches vanished by day 12, and my makeup sits better — no cakiness on the nose. But it didn’t erase my pores, and I still needed an eye cream. It’s hydration, not a face-lift.

Buy if
You’re oily-combo or live in humidity — this gives you glow without the grease.
⏭️

Skip if
You have Sahara-dry skin in winter — you’ll still need a cream over this in the PM.
💰

Worth it?
At $78, it’s a splurge. But it replaces a $50 moisturizer, so the math kinda math’s.

6.🏁The Final Glow-Up

Yes, it can replace your moisturizer — if your skin isn’t desert-level dry. It’s a solid one-and-done for the humid months, and a great base for a heavier cream in winter.

8.2/10
Genuine glow, not just marketing shine.
