Skincare longevity and the power of CO2

CO2 Renew uses your body’s own oxygen-delivery mechanism to bring more oxygen to the skin where it’s applied. The result is skin that’s better nourished from within: smoother, brighter, and more resilient over time.

Why CO₂

CO₂ is the catalyst that determines whether oxygen reaches your tissues. By raising CO₂ levels in the skin and muscle, AEIR taps a powerful biological effect that improves circulation, calms inflammation, and speeds recovery at the cellular level — no needles, no drugs, no downtime.

How it works

How CO₂ Renew supports healthy skin function

CO₂ Renew improves the environment in which skin cells need to do their job and support total skincare health and longevity. From wound healing and post-surgery, to premature aging, acne, dryness, and much more.

Step 1

Apply

CO₂ is delivered directly in the skin and penetrates the stratum corneum (the outermost layer of the skin), before it fully activates.

Step 2

Absorb

The formula reacts naturally with water inside the skin and generates CO₂ directly within the tissue – this concentration of CO₂ inside the skin helps the CO₂ drive from the outer layers into all layers of the skin for maximum impact.

Step 3

Release

The rise in CO₂ triggers vasodilation and activates the Bohr Effect, prompting red blood cells to release more oxygen where it's needed, as well as improved circulation and cellular function.

Step 4

Recover & Repair

The improved tissue environment supports healthy skin function including cellular metabolism, inflammatory balance, collagen organization, hydration, and barrier function.

How to apply

Four simple steps.
One powerful outcome.

How to use it

  • Start with clean, completely dry skin.
  • Apply a thin, even layer.
  • Let the paste activate for at least 10 minutes.
  • Rinse with warm water (or leave on as part of your last step in your routine).

Skincare benefits

Better oxygen. Better skin.

Skin cells run on oxygen, and most skincare never touches the supply, until now. By triggering the Bohr Effect at the surface, it prompts your blood to release more oxygen into the skin and feeds the cells that keep it firm, even, and resilient. The result builds with use: a healthier glow, smoother texture, and more even tone.

Circulation & oxygen delivery

Provides your skin with better access to oxygen and nutrients needed for repair and renewal

Cellular metabolism

Provides skin cells with energy needed to function, recover, and maintain health turnover

Inflammatory balance

Allows skin to respond appropriately to stress and avoid irritation or sensitivity

Collagen organization

Repair is faster and higher quality with better structure and resilience

Hydration balance

Ensures hydration support through barrier function and intracellular water production

Barrier recovery

Skins becomes more resilient, less reactive, and better equipped to tolerate treatments and stress

AEIR CO₂Renew is a topical formula that generates CO₂ when activated on the skin, bringing CO₂ technology into a skincare routine.

CO₂Renew is designed for a refreshed, healthy-looking complexion. Research on topical CO₂ has explored changes in skin function, healing, and regeneration.

Apply a thin layer to clean, dry skin. Let the formula activate for at least 10 minutes. Rinse with warm water or leave on as last step in routine. Avoid broken open skin unless instructed otherwise.

CO₂Renew is designed to fit into a daily skincare routine, safe to use multiple times per day.

Yes, use CO₂Renew first, rinse, and then continue with your usual topicals, serums, and moisturizers.
