Oxygen

Oxygen is a gas that exists naturally within the skin's structure and bloodstream. In skincare products, it is included as a skin conditioning agent, though its presence in topical formulations is relatively uncommon, appearing in roughly 0.1% of skincare products on the market.The skin relies on adequate oxygen levels to maintain healthy cell function and support key processes like collagen synthesis and wound repair. Different layers of skin maintain varying oxygen gradients, which are essential for normal physiological behaviour.

Skin cells are aerobic, meaning they require oxygen to generate energy and carry out essential functions. The skin receives oxygen through blood circulation and maintains specific oxygen gradients across its different layers — the epidermis, dermis, and deeper structures each have distinct oxygen levels that are critical for normal cell behaviour.When cells have adequate oxygen availability, they can more efficiently synthesise collagen, regulate inflammation, and support barrier function. Conversely, chronically low oxygen levels in skin can contribute to cellular stress and accelerated ag…

If using a product containing oxygen, apply as directed by the product instructions. Bear in mind that oxygen's effectiveness in topical skincare is still being evaluated, and results may vary. Products containing oxygen work best as part of a consistent routine that includes sun protection and evidence-backed ingredients like retinoids and antioxidants.

Oxygen is a naturally occurring component of skin and is generally considered safe in skincare formulations. No significant safety concerns have been documented for topical use.
