You’re slathering this on over moisturizer like it’s a finishing oil. Stop. That’s how you waste £55.
The Marine Silk Serum is a water-based treatment — it needs bare, damp skin to actually penetrate. Layer it after cleansing, before anything occlusive. Your moisturizer seals it in, not the other way around.
It’s a lightweight serum from Haeckels, the Margate-based brand that harvests seaweed from their own beach. £55 for 30ml. The claim that made me add to cart: “visible plumping in 7 days.” I called bullshit. Then my laugh lines looked less like parentheses by day 4.
Silt-like texture
Thicker than water but thinner than gel — think liquid silk with grit.
Seaweed-first base
No water filler. The first ingredient is actually bladderwrack extract.
Zero fragrance
Smells like low tide. Not in a bad way — just honest.
Three ingredients do the heavy lifting here. The rest is just suspension. No fairy dust — just things that actually work on skin biology.
- Bladderwrack: Marine collagen booster — plumps without irritation
- Hyaluronic Acid: Holds 1000x its weight in water — but only on damp skin
- Vitamin E: Stabilizes the formula and calms redness — not just preservative
- Sea Buckthorn: Fatty acids + antioxidants — glow, not grease
First pump — it’s slippery, almost snot-like. 10 seconds later, it’s gone. No tacky film, no waiting around. Your skin feels like you just did a sheet mask but without the dripping.
Week 2: My forehead stopped looking like crepe paper. Week 3: My friend asked if I “did something.” I didn’t. The serum did. The only downside — it pills if your moisturizer has silicone. Switch to a cream without dimethicone.
Fine lines softened by ~30%. Pores looked smaller in the morning. But it did nothing for my dark circles — that’s a circulation thing, not a topical fix. Don’t expect a facelift in a bottle.
This is a smart, specific serum that earns its price tag if you respect the layering. Don’t be lazy with it — your glow depends on the order.
