🌞 **The Oxygen Con That Works**

Day one, I shook this bottle like a martini, applied it, and my skin looked like I’d just done a facial. Not a filter-glow. That weird, plump, *expensive* look. By day 30, I stopped pretending it was a gimmick. The real win? My pores stopped throwing shade at midday. They just… stayed invisible.

Here’s the part that got me: I forgot to use it for three days in week two. My skin didn’t throw a tantrum. Just quietly looked less like a glass of champagne and more like flat soda. That’s when I knew it was doing something real.

🔬 **The Bi-Phase Breakdown**

It’s £58 for 30ml. The claim that hooked me: “delivers oxygen to skin cells for instant radiance.” Sounds like pseudoscience. I bought it anyway.

1

Bi-Phase Shake

Two liquids that separate. Must shake. If you forget, you get oil slicks, not glow.

2

Oxygen Delivery

They say it carries oxygen molecules to skin. I don’t care how. My skin looked less tired at 3pm.

3

Instant Absorption

Sinks in under 20 seconds. No sticky residue. You can slap makeup on immediately.

📸 **What’s Actually Inside**

The hero is **Oxygenated Perfluorodecalin** — fancy name for a molecule that carries oxygen. Sounds sci-fi. Works like a breath of fresh air for your face. Then there’s **Hyaluronic Acid** (the usual hydration trick), **Niacinamide** (calms redness and fades dark spots slowly), and **Vitamin C** (brightening, but not the burn-your-face-off kind).

  • Oxygenated Perfluorodecalin: Carries oxygen into skin for that instant plump
  • Hyaluronic Acid: Holds water so you don’t look crepey
  • Niacinamide: Reduces redness over time, not overnight
  • Vitamin C: Gentle brightening, no irritation

💧 **The Texture Diaries**

It’s a lightweight oil-water hybrid. Feels like silk water. Not greasy. Not sticky. Just slides on and disappears. Week one: I was convinced it was overpriced water. Week two: my skin started looking *consistent*. No random dry patches. No weird shiny T-zone. Just even. Week three hit — and my makeup didn’t settle into fine lines. That’s when I stopped questioning the price.

💡 **One Thing** Apply it to *damp* skin after toner. Dry skin drinks it too fast and you lose the slip. Two drops, press don’t rub.

✨ **The Real Results**

Measurably: My skin looked brighter by week two. Pores visibly smaller by week three. Redness around my nose? 70% gone. What didn’t change: my dark circles. This isn’t a concealer. Also not great for deep cystic acne — it’s a glow serum, not a treatment.

Buy if
You have dull, dehydrated skin and want a glow without glitter or irritation
⏭️

Skip if
You have severely oily skin — the oil phase might feel heavy for you
💰

Worth it?
Yes, if you can afford £58. Results are real but subtle. Not a miracle, just excellent maintenance.

📝 **Final Call**

It’s a brilliant daily glow serum, not a life-changing treatment. If you want your skin to look like you slept 8 hours when you slept 5 — this is your bottle.

7.8/10
Reliable glow, not a miracle
