AO2 Clear: The Ultra-Clean Acne Treatment
AO2 Clear is a skincare brand known for pioneering oxygen-based skin treatments through patented nanobubble technology. Their innovative formulas deliver high concentrations of oxygen deep into the skin, helping to clear acne, calm irritation, and support overall skin health without the use of harsh chemicals. With a commitment to purity, safety, and scientific integrity, AO2 Clear offers a clean, effective alternative for anyone seeking gentle yet results-driven skincare.
AO2 CLEAR®, the brand’s flagship product, is formulated with only two ingredients: distilled water and oxygen nanobubbles. This simple but powerful technology targets anaerobic bacteria—the root cause of acne by flooding the pores with oxygen. Since acne-causing bacteria cannot survive in oxygen-rich environments, this treatment helps reduce breakouts on contact while supporting a healthy skin barrier. AO2 CLEAR is suitable for all skin types, including those who are pregnant, nursing, or trying to conceive, as well as individuals with highly sensitive or reactive skin.
Customers also report additional benefits, including improved hydration, smoother texture, and faster recovery after treatments such as Fraxel, chemical peels, and microneedling. The formula is completely free of parabens, fragrances, and irritating additives, making it an ideal solution for clean skincare users who want results without compromises.
AO2 Clear originally launched with this single hero product. Each box contains four 150 ml pouches, each filled with billions of stable oxygen nanobubbles. These nanobubbles remain suspended due to their natural stability and the brand’s custom-designed pouches. To preserve oxygen density and efficacy, users are advised to close the cap tightly after each pour to minimize air exposure.
Key benefits of AO2 CLEAR:

Ingredients: Distilled water, oxygen nanobubbles.
Building on the success of their hero product, the brand recently introduced AO2 HYDRATE, a radically clean hydrating formula powered by oxygen nanobubbles and natural vegetable glycerin. AO2 HYDRATE is designed to deliver deep, lasting moisture while supporting skin barrier health with unmatched simplicity and purity.
The oxygen nanobubbles help transport moisture into the skin at a deeper level, while glycerin acts as a natural humectant to lock in hydration. This synergy helps soothe irritation, promote cellular renewal, and leave skin plump, smooth, and refreshed. AO2 HYDRATE is especially beneficial for sensitive, post-procedure, acne-prone, or mature skin that struggles with heavy or synthetic moisturizers.
Key benefits of AO2 HYDRATE:
-
Deep, cellular hydration that plumps and revitalizes
-
Calms redness, irritation, and dryness
-
Strengthens the skin barrier for smoother, softer texture
-
Locks in moisture with natural vegetable glycerin
-
Enhances absorption of serums and moisturizers
-
Safe, lightweight, and suitable for even the most sensitive skin
Ingredients: Distilled water, billions of oxygen nanobubbles, natural vegetable glycerin.
AO2 HYDRATE offers a science-backed, minimal-ingredient approach to deep hydration and barrier repair. With every use, the skin feels more nourished, balanced, and resilient. Together, AO2 CLEAR and AO2 HYDRATE deliver a clean, oxygen-powered skincare experience focused on clarity, calm, and radiant skin health.
