Carboxy therapy: what it is and what CO2 does for the skin

Carboxy therapy sounds more complicated than it is. A gel is applied that releases carbon dioxide, and the gas triggers a response that brings more oxygen into the skin. The session runs 60 minutes and costs €70.

How does carbon dioxide oxygenate the skin?

It sounds contradictory, but it is simple physiology. When CO2 concentration in tissue rises, haemoglobin in the red blood cells releases oxygen more readily — the body reads it as a sign that the tissue needs oxygen. The result is better local blood supply, faster metabolism and more active protein synthesis.

In practice that means the skin receives more oxygen and nutrients, and clears waste faster.

What does it help with?

Carboxy therapy suits a dull tone, tired skin, inflammatory acne and uneven colour. On the body it is also used for stretch marks and cellulite. Skin tends to feel firmer and more elastic afterwards, with a more even tone.

It is not a filler and not a substitute for surgery — it improves the condition of the skin, not its contour. If you are after a change in structure, microneedling is the better fit.

Is it uncomfortable?

Most people describe a light tingling or fizzing that lasts a couple of minutes and passes. There is effectively no downtime — mild redness usually clears within the hour, which makes it a reasonable choice before an event.

Who should avoid it?

Not during pregnancy, or with open wounds, an active skin infection, or severe inflammation. Arrive without make-up and avoid exfoliating products for a couple of days beforehand.
