My face drank this serum before I did my morning coffee. That’s not a metaphor — it literally vanished into my skin in about 12 seconds flat.
The real flex? No hyaluronic acid. None. In a winter serum. Which means it won’t suck moisture out of dry air and leave you tighter than a kilt.

❄️ **The 72-Hour Hype**
It’s a lightweight gel-serum from a Scottish brand that forages its own seaweed. £38 for 30ml. The claim that got me: “72-hour moisture retention.” I laughed. Now I’m quiet.
No HA, no cry
Uses a seaweed polysaccharide complex instead — it holds water differently, doesn’t rely on humidity to work.
Sinks, doesn’t sit
Zero tackiness. I can put sunscreen on 20 seconds later without pilling.
Smells like low tide
In the best way. No fragrance — just pure, briny, honest seaweed.

💧 **What’s Actually Inside**
Three seaweeds — bladderwrack, sugar kelp, and dulse — plus a fermented oat extract. No fillers, no silicones, no “proprietary blend” nonsense. Just stuff that grew in the Atlantic.
- Bladderwrack: Locks water into the upper layers without sitting heavy
- Sugar kelp: Contains natural humectants that work in low humidity
- Dulse: Mineral-rich, soothes redness from winter wind
- Fermented oat beta-glucan: Calms irritation and reinforces barrier

🧴 **Feels Like… Nothing**
Texture is a shock — it’s almost watery. Drops out of the pipette like thin syrup, then disappears. First use I thought I didn’t put enough. Checked the mirror. Nope, skin just drank it.
Week two surprise: my t-zone wasn’t an oil slick by noon. Weird for a hydrating product. I think the seaweed is actually regulating sebum, not just dumping moisture on top.

🌿 **The Verdict (Real Talk)**
My fine lines around the eyes are less angry. My nose isn’t flaking. But my cheeks still need a cream on top if it’s below freezing. It’s hydration, not a moisture seal.

🧪 **Bottom Line**
Best non-HA hydrator I’ve used in winter. Doesn’t solve everything, but what it does — sink in fast and hold — it does better than most.
