What is Hyperbaric Oxygen Therapy?

After a brief check-in, you settle into the chamber fully clothed for the pressurisation phase. As the pressure rises, you may notice a gentle fullness in your ears, similar to the feeling on a descending flight, which eases if you swallow or yawn. Once at pressure, the rest of the session is yours to rest, read or simply unwind.

No. A session is comfortable and non-invasive. The only sensation most clients notice is a gentle fullness in the ears during pressurisation, relieved by swallowing or yawning.

Allow around an hour at the clinic

It increases the oxygen available to your bloodstream while you rest in a pressurised chamber. Clients typically seek it to support recovery, complement their aesthetic treatments and promote energy and clarity. Individual experiences vary.

None. You can return to your day as normal. We advise staying well hydrated before and after your session.

That depends on your goals. Many clients choose a course of weekly sessions or a short intensive block, followed by maintenance. We can advise a cadence at consultation based on what you want to achieve.

HBOT is a gentle, non-invasive treatment, and our chambers are operated by trained team members who stay with you throughout your session. Before your first visit we take a full health history at consultation to confirm the treatment is appropriate for you. A small number of conditions are not suitable for pressurised environments; we will talk these through with you honestly at consultation so you can make an informed decision.

Very little preparation is needed. We ask that you arrive well hydrated, as this supports oxygen uptake, and that you avoid strenuous exercise immediately before your session. Wear comfortable clothing and avoid perfumes or aerosols on the day.

Yes, and many clients do. Skin is oxygen-dependent tissue, so supporting the body’s oxygen availability sits naturally alongside facials, skin boosters and laser treatments while the skin is in its repair cycle. We will advise on sequencing at your consultation, so each treatment supports the next.

Session pricing depends on the protocol we recommend and whether you choose a single session, a weekly course or an intensive block. Packages are available on selected treatments, and we are happy to prepare a bespoke plan on request. Single sessions are also available to book.
