❄️ **Scottish Seaweed Saved Me**

My chin started flaking like a croissant by week two of January. This serum was the only thing that stopped it — without turning me into a greaseball.

Every other “winter savior” either sat on my skin like Vaseline or did nothing. This one actually sinks in. The real win? My moisturizer stopped pilling over it.

💧 **The Basics, Fast**

Isle of Skye Rainfall Serum — $48 for 30ml. The brand claims it “replenishes moisture barrier using wild-harvested seaweed.” I tried it because I’m a sucker for anything harvested by someone in a raincoat.

1

10-second absorption

Pat it on and it’s gone. No sticky wait before sunscreen.

2

No fragrance whatsoever

Smells like nothing. Which I prefer to “oat milk and anxiety” notes.

3

One dropper is plenty

Three drops covers my whole face. This bottle will last forever.

🌿 **Ingredients That Actually Do Things**

The hero is *Ascophyllum nodosum* (knotted wrack seaweed) — grows in the North Atlantic, packed with minerals that calm inflammation. They also threw in glycerin and squalane for hydration without clogging.

  • Knotted wrack: calms redness + strengthens barrier
  • Glycerin: draws moisture in without stickiness
  • Squalane: mimics your skin’s natural oils
  • Sodium PCA: keeps water locked in all day

🧴 **Feels Like Nothing (In a Good Way)**

It’s runny — almost like water with a tiny bit of slip. I patted it on after cleansing and it disappeared before I finished my coffee. No film. No shine.

Week two hit and I noticed my forehead wasn’t tight after showering. That never happens. The weird part? My pores looked smaller. Didn’t expect that from a hydrating serum.

💡

One Thing: Apply to damp skin — straight out of the shower. It locks in way more moisture than patting on dry.

📅 **The Honest Results**

Flaking gone by day 4. Skin felt bouncier by day 10. Still had some dryness around my nose on super cold days — but way less than usual.
