Not a serum. Not a cream. A therapy.
You've tried the serums. You've hit the ceiling of what topicals can do. CO2 Renew is a different category. It's topical carboxytherapy — the therapy Japanese cosmetic clinics and European rehab centers have used for decades. Now in a paste you apply at home.
Here's what happens on your skin. The paste releases CO₂ through the skin. Local CO₂ rises. Your hemoglobin lets go of the oxygen it's already carrying. That oxygen reaches the tissue underneath. Blood flow opens up. Repair starts. You feel a gentle warmth. The skin flushes. Then it settles.
One paste. One physiological mechanism. Dozens of applications.
The Mechanism
One mechanism. Three ways it works.
Oxygen, delivered where it's needed.
Your blood is already ~97% oxygen-saturated. The question isn't supply. It's delivery. Raise local CO₂ and hemoglobin lets oxygen go — straight into the tissue. That's the Bohr Effect. It's how your muscles pull oxygen during exercise. CO2 Renew borrows the same signal and puts it on your skin.
Christian Bohr, 1904. See also Nybo & Rasmussen, 2007.
The skin repairs itself faster.
Repair needs circulation. Transcutaneous CO₂ opens the tiny vessels under your skin. More blood reaches the tissue. More oxygen reaches the cells doing the repair work. In studies on the hardest-to-heal patients, that microvascular boost showed up clearly. A clinical trial in healthy adults confirmed the paste's safety and efficacy.
Transcutaneous CO₂ for diabetic foot ulcers; Exploratory clinical trial of carbon dioxide paste.
Circulation you can measure.
Thermal imaging picks up the change after one dry CO₂ session. Peripheral circulation goes up. The same signal quiets local inflammation. Muscle tissue recovers faster after stress.
Sakai et al. — dry CO₂ bathing; Transcutaneous CO₂ accelerates muscle injury repair (rat model).
What Compounds
Your first use, you'll feel it. A month in, you'll see it.
Most people notice a subtle glow the first time. That's circulation opening up. Benefits compound with use. At three times a week, early users tell us they see tone and clarity shift inside the first month.

Use Cases
Three use cases. Same tube.
Post-workout spot therapy
Apply to the calf that won't settle, the shoulder that's barking, the low back that stiffened on the drive home. 20 minutes. Rinse.
Acute flare-ups
The tweak you feel at hour 36 after a heavy session. Circulation is the signal your tissue is waiting for.
Chronic joint areas
Knees, elbows, wrists. Comfortable enough for daily use.
No device. No setup.
Comfortable at skin temperature. Open and apply — that's the whole setup.
Face & neck
Apply after cleansing, before treatment serums. Works beneath the surface, not on top of it.
Post-procedure
Peels, microneedling, laser. CO2 Renew supports the repair window when circulation matters most.
Skin cells, better fed
CO₂ opens the small vessels under your skin. More oxygen reaches the cells that make collagen. Cells that get oxygen heal faster and look healthier. This is the signal behind clinical carboxytherapy.
Layers with your routine
Layers with your existing routine. Doesn't replace it.
TSA-friendly
10mL tubes. Toss five in a Dopp kit. No device. No electricity.
On-road recovery
The race you flew to. The tournament weekend. The hotel-room hamstring.
Shelf-stable
Store at room temperature. Open when you need it.
Fits in your bag
The recovery tool that goes where you go. No charger. No case. Just tubes.
How to Use
Simple enough for tonight.
Apply
Spread a thin, even layer on clean, dry skin. The target area: face, joints, or muscle.
20-minute wait frame
Wait 20 minutes
Feel the gentle warmth as circulation opens. Read. Scroll. Breathe.
Rinse frame
Rinse
Warm water. Follow with your regular serums or moisturizer. Resume your day.
Recommended frequency: 3× per week for compounding results.

From Ross — Founder, DC
I built the paste because I can't physically treat everyone.
I'm a chiropractor. A biology degree sits in a drawer somewhere. For the last decade I've been treating athletes and patients with transcutaneous CO₂. It works. And the research behind it is older and deeper than most people realize.
The suit is the clinical experience. But one clinician sees only so many patients a week. The paste scales the mechanism. One tube in a medicine cabinet reaches people I could never treat in person.
Under three dollars a treatment. No device. Same Bohr Effect. That's what I built. — Ross
