Why Oxygen Matters in Skincare

Have you noticed that some people who exercise regularly seem to have a better complexion and more radiant skin?

Many factors affect skin condition. Could one reason be that exercise promotes blood circulation, giving skin a chance to receive more oxygen?

We believe this question is worth bringing into everyday skincare: beyond hydration, sun protection and skincare ingredients, how much do we know about skin's need for oxygen?

This is where Oxora's interest in skin oxygenation begins.

Skin uses oxygen every day

Good skin condition depends on the work skin does every day. Cells need to renew, and the outer barrier needs to be maintained; all this work requires energy. Oxygen takes part in the process by which cells turn nutrients into usable energy, making it one of the important conditions that support normal skin function. Put simply, for cells to work effectively, they need energy, which is closely tied to a suitable oxygen environment.[1]

Skin receives oxygen not only through blood circulation but also from outside. Human research has found that the superficial layers of skin can absorb oxygen from their surroundings to supplement local needs.[2]

But having an oxygen source is only part of the story: oxygen must also be able to reach cells. In chronic dermatitis, including eczema, the affected area may thicken or swell.[3] From the perspective of oxygen diffusion, these changes may make it harder for oxygen to reach cells; if the local oxygen supply cannot meet cellular needs, there may be an oxygen shortfall.[2]

Oxora therefore asks: when local oxygen supply limits normal skin function, can a skincare product suitable for daily use help improve the conditions for oxygen supply? Through formulation design, we hope to make usable oxygen more readily available to skin.

How skin builds its own barrier

When we think of the skin barrier, hydration, moisturising and locking in moisture may come to mind first. These forms of care have their place, but whether skin retains water also depends on the integrity of the barrier itself. Healthy skin naturally loses some water through its surface, known as transepidermal water loss (TEWL); when the barrier is damaged, water often escapes more easily and skin becomes drier.[4]

To maintain an intact barrier, skin must continually make and renew its own protective layer. Keratinocytes gradually mature and differentiate as they move upward from the basal layer of the epidermis, eventually forming the outermost stratum corneum. These cells and orderly arranged lipids together form a barrier that helps reduce excessive water loss.[5,1]

This process of skin-cell renewal and normal cell metabolism requires energy, and a suitable oxygen environment is one of the important conditions supporting cell maturation and differentiation.[6,7] So, as well as hydrating and retaining moisture, barrier care should consider whether cells can receive a suitable oxygen supply to support skin as it builds and renews its own protective layer.

Helping skin hold its ground

Skin faces outside irritants every day and continually lives alongside microbes on its surface. Maintaining its own defences is part of good skin condition.

Oxygen also takes part in this defensive work. An experiment with human immune cells found that an inadequate oxygen supply weakened the cells' ability to deal with Staphylococcus aureus; when oxygen supply was restored, that ability recovered too.[8]

We use 'host advantage' to describe this direction. Put simply, it means helping skin hold its ground: when an inadequate oxygen supply hampers normal defence, improving those oxygen conditions may allow skin to regain its own defensive ability.

This does not mean oxygen directly kills bacteria. Staphylococcus aureus can also survive in an oxygen-rich environment; our focus is on the conditions for skin's own defences.

Oxygen in beauty care

Oxygen facials have become one direction in beauty treatments. For example, the beauty-treatment brand Glo₂Facial promotes improved skin radiance and texture. According to its official description, the treatment uses a dedicated device, combining exfoliation with a carbon-dioxide reaction at the skin surface to encourage the skin to obtain oxygen from within.[9] This differs from Oxora's approach using oxygen nanobubbles, but it reflects a direction for skin oxygenation in beauty care.

Medicine also uses hyperbaric oxygen therapy (HBOT) and topical oxygen therapy (TOT). Although their purposes and methods of oxygen delivery differ from everyday skincare, the related research shows that oxygen supply is a broad field of study and offers research context for Oxora's exploration of oxygen-supply formulations.[10,11]

Oxora and oxygen nanobubbles

Oxygen nanobubbles can be understood as extremely small oxygen-carrying bubbles in water. These bubbles carry molecular oxygen, and the design aim is for that oxygen to be released after application, increasing the oxygen available locally.

Oxora uses proprietary nanotechnology to introduce oxygen nanobubbles physically into MEM-Activated Water, then combines it with a lightweight hydrogel to make our Skin Base Fluid. Effectively storing and releasing oxygen is one of the formulation's main design aims. In medicine, researchers have also explored oxygen-nanobubble hydrogels as wound dressings; those experimental studies provide valuable reference points for our research.[12]

Giving skin a chance to use it

For Oxora, the key question is whether skin can actually use that oxygen. This is what we mean here by 'oxygen bioavailability'. Oxygen in the bottle is only the beginning: can it be retained through storage? Can it be released on application? Can it reach a place where skin has a chance to use it?

These are questions to measure in the finished Skin Base Fluid. Nanobubbles are a way to carry oxygen; supporting skin's normal daily work is the purpose behind the design.

The same thinking runs through Oxora's Micro-Environment Modulation approach: considering hydration, surface acidity and local oxygen conditions together, instead of looking for one ingredient to do all the work. Skin maintains its own function within these conditions every day.

Next time you choose skincare, look at the ingredients. Then ask one more question: what suitable conditions for my skin's work can this care provide?
