THE FUTURE OF SKINCARE IS HERE

AO2 SKIN™ is revolutionizing skincare with patented nanobubble delivery technology. Our products use nanobubbles 1/1000th the size of a pore to deliver beneficial gases deep into the skin, providing all skin types with radically clean, simple yet effective solutions without harsh chemicals or long ingredient lists.

What Makes AO2 SKIN Different?

Traditional skincare often depends on long ingredient lists and harsh actives that sit on the surface. AO2 SKIN™ takes a science-first approach, using gas nanobubbles to transform skin from the inside out.

Each nanobubble is smaller than a single pore, allowing beneficial gases to reach the deeper layers of skin where real change happens. The result is visibly clearer, calmer, more hydrated skin without irritation or complexity.

WHAT ARE GAS NANOBUBBLES?

Gas nanobubbles are billions of microscopic bubbles, each smaller than a skin pore, that carry beneficial gases deep into your skin. Unlike traditional formulas packed with chemicals, AO2 SKIN™ uses nanobubbles to deliver targeted results — starting with oxygen for clarity (AO2 CLEAR) and for hydration (AO2 HYDRATE).

CLINICAL RESEARCH

Evidence of Oxygen Delivery Beneath the Skin Surface Without Disrupting the Skin Barrier

Researchers examined what happens inside human skin after topical application of AO2 SKIN’s oxygen nanobubbles, including oxygen penetration and skin barrier integrity.

THE STUDY

The First-of-Its-Kind Human Oxygen Nanobubble Enzyme Study

Conducted in collaboration with North Carolina State University and a board-certified dermatologist and nano-physicist, this study examined human skin biopsies collected before treatment and at 30- and 60-minute intervals following topical application of AO2 SKIN oxygen nanobubbles.

  • Human skin biopsies collected and analyzed directly
  • Quantitative immunofluorescence imaging
  • Independent academic research collaboration
  • Evaluation of oxygen-related biomarkers and skin barrier integrity

HOW OXYGEN WAS MEASURED

Your Skin Has It’s Own Oxygen Sensor

Your skin naturally has different oxygen levels at different depths. One important marker, called Hypoxia Inducible Factor-1 alpha (HIF-1α), helps scientists understand how much oxygen is available in the skin. When oxygen levels increase, this marker goes down.
 
Participants applied oxygen nanobubbles of AO2 CLEAR to their skin. Small skin samples were taken before use, and again after 30 and 60 minutes.

FINDING 01

Oxygen Actually Reaches The Epidermis and Dermis

The study measured HIF-1α, a biomarker that rises when skin is low on oxygen and drops when oxygen improves. After applying AO2 SKIN, HIF-1α decreased significantly; direct biochemical proof that oxygen was delivered into the tissue.
 
  • HIF-1α is a validated scientific measure of tissue oxygenation
  • Results were significant at both 30 and 60 minutes
  • This is the body’s own oxygen sensor confirming the positive penetration and effects of AO2

FINDING 02

Your Skin’s Own Defenses Get Stronger

Beyond oxygenation, the study found that AO2 SKIN activates the skin’s natural antioxidant defense system. Two key protective enzymes, NQO1 and HO-1, increased significantly, and HO-1 kept rising through 60 minutes, suggesting a lasting protective effect.
 
  • NQO1 elevated at 30 minutes — fast activation
  • HO-1 continued rising through 60 minutes — sustained defense
  • AO2 gives the skin a very strong defense after treatment.
  • Skin becomes more resilient to environmental stressors

FINDING 03

Your Skin Barrier Stays Completely Intact

Filaggrin, the key protein responsible for your skin’s barrier function and hydration, showed zero change across all time points. The treatment delivers oxygen without disrupting the skin’s protective layer.
 
  • Filaggrin levels unchanged at T0, T30, and T60
  • No disruption to the stratum corneum structure
  • Safe and non-disruptive — confirmed at the cellular level

WHAT THIS MEANS FOR YOUR SKIN

Better Oxygen. Stronger Skin. No Disruption.

  • Supports better oxygen availability at the pore and follicle level
  • Helps create a healthier environment for skin function
  • Maintains skin barrier integrity
  • Encourages a more balanced, resilient complexion
This research supports how oxygen nanobubble technology from AO2 SKIN works to improve overall skin health in a gentle, non-disruptive way.

    “I enjoy using AO2 considering that my skin got very dry from acne treatments, and I wanted something that is good for acne without harsh chemicals and over-drying.”

    Alexandra

    "AO2 Clear truly gave me my confidence back! After struggling with hormonal acne, eczema and the most sensitive skin, I was skeptical, but it exceeded all expectations. I will never not use this in my routine. I 1000% recommend!"

    madeline

    "I just started using AO2 a couple of weeks ago and I can already see a difference. My pores on and around my nose have gotten smaller and the tone of my face has really improved. It also feels really good during application and after I use it for the next couple of hours. My teenage kids also really like it and have noticed an improvement in their complexions. I look forward to using it each day."
