One of the most effective ways to reduce the first signs of skin ageing is oxygen therapy. It delivers oxygen deep into the skin’s layers in a painless way, instantly firming the skin.
But oxygen therapy offers so much more than that!

It also restores a sallow complexion, giving your skin a radiant glow once again. Plus, it helps to calm inflammation and purify the skin – making it an effective treatment for acne as well.
Oxygen therapy is an advanced treatment that combines pure oxygen with nourishing serums, delivered to the deeper layers of your skin. This powerful combo stimulates new skin cell production, boosts collagen levels, and provides deep hydration.
The treatment consists of several steps. We always begin with a thorough cleansing and exfoliation to remove impurities and dead skin cells. Next, we infuse the skin with oxygen and active serums using a gentle blast technique that reaches the deeper layers.
A full facial massage is also included to stimulate blood circulation and enhance the absorption of active ingredients. We don’t just treat your face, the skin on your neck and décolleté gets the same care.
To finish, we apply a customised day cream to leave your skin in top condition.
Oxygen therapy is suitable for all skin types and is 100% painless. This makes it the perfect treatment!
This blissful 80-minute facial offers a wide range of benefits:
As mentioned, the effects are immediate, making it the perfect treatment before a party or special event. For longer-lasting results, we recommend a course of multiple treatments. This way, your skin is continuously renewed and stimulated – leaving you with a healthy, radiant glow at all times!
The price for a single treatment is €131. Starting a course? We offer affordable multi-treatment passes for 5 or 10 sessions, with discounts of up to €150!
You can book oxygen therapy 7 days a week at the Beauty Clinic at Thermae Grimbergen. Call 02 270 81 96 now to make your appointment. Or complete our contact form , and we’ll get back to you as soon as possible.
