Reduces, Remodels, Regenerates: the 3 actions of Coolwaves™

Featuring the latest ultra-new Coolwaves™ microwave technology, ONDA reduces localised fat cells whilst tightening and remodelling the skin. Body tissue is firmed up using non-invasive coolwave energy with long-lasting results.

Welcome to the next generation of body-sculpting devices.

Onda Micro Coolwaves™: How it Acts on Cells and Metabolism

The treatment is highly effective on stubborn fat pockets around the body, particularly the tummy, love handles and thighs. It cleverly targets fat adipose cells, while leaving the surrounding tissue intact. The coolwave energy also stimulates cellular metabolic processes and collagen production, and is highly recommend for body sculpting and reshaping of the silhouette.


FAT REMOVAL: It penetrates deeply into the fat layer, demolishing the cell membranes of subcutaneous adipose cells and actively dissolving localized fat deposits. The fat is then eliminated by natural cellular metabolism (lipolysis).
CELLULITE REDUCTION: It stimulates the connective tissues surrounding the adipose lobules of the cellulite, diminishing the “orange peel”effect.
SKIN TIGHTENING: It causes the contraction of collagen fibres in the dermis, stimulating production of new collagen which in turn tightens and tones the body.

This body sculpting treatment is not a weight loss treatment, but it is designed for adults with stubborn excess fats, with loose skin or with resistant cellulite.

Onda Micro Coolwaves™: Safety and Wellness

Onda Micro Coolwaves™ mechanism of action is deep and targeted, and does not damage the skin or surrounding tissues. It emits microwaves at precisely 2.45 GHz, a level at which is only absorbed by fat adipose cells. At the same time, the treatment emits radiofrequency waves to disperse energy at the superficially dermal and epidermal level.

The treatment is highly effective and comfortable as only 20% of the energy goes to the dermis (the heat produced is counterbalanced by a cooling system). The remaining 80% penetrates into the fat.

Comfort & Skin Preserved with an Integrated Cooling

The treatment cleverly comes with a skin cooling system that is activated upon contact with our skin. By cooling the skin during treatment, it creates a counterbalance to the heat emitted by the microwaves at deeper levels. The skin is hence protected and preserved, ensuring client comfort and reducing potential side effects such as burns or inflammation.

What areas can be treated with Onda Micro Coolwaves™?

The Onda Micro Coolwaves™ treatment is particularly effective on stubborn areas of fat on the stomach, love handles, thighs, saddlebags, back and upper arms. We can also target cellulite on the thighs, buttocks and arms.

Is Onda Micro Coolwaves™ treatment painful?

Not at all. Most people feel a gentle warmth under the skin with a feeling of coolness on the skin itself. The treated area remains warm for a few hours afterwards.

How long does an Onda Micro Coolwaves™ treatment take?

Each treatment covers a 15x15cm area and takes approximately 10 minutes. It is possible to have multiple (up to 8) areas treated in each session.

Are there any side effects of treatment with Onda Micro Coolwaves™?

Mild side effects include itching, numbness, hardness, warmth, tenderness, redness and swelling. Less commonly, it is possible to develop mild bruising, nodules or blisters at the treatment area, which are usually transient and resolve within a few days after the treatment. 

Are there any contraindications to Onda Micro Coolwaves™ treatment?

Unfortunately, people with the following conditions are not suitable for this treatment:

  • Pregnancy
  • Heart failure
  • Metal implants or pacemakers
  • Severe clotting disorders
  • Current or recent cancer
  • Severe vascular disease
  • Skin disease in the treatment area
  • Uncontrolled diabetes
  • Age <18

Will Onda Micro Coolwaves™ treatment help me lose weight?

If only it were that easy! Onda Micro Coolwaves™ is a body-sculpting system that is designed for localised areas of stubborn fat and cellulite in people whose BMI is less than 30. Unfortunately, it is not a weight-loss treatment. It can, however, be used in conjunction with your healthy diet and exercise plan to optimise results.

Are there any pre-treatment instructions?

To get the best results from your Onda Micro Coolwaves™ treatment, we advise that you avoid any moisturiser or emollient on the treatment area for 48 hours prior to each session. If the skin is dry, it allows for easier passage of the Coolwaves™ through to the target subdermal fat layer.

To assist with lymphatic drainage, you should drink an additional litre of water per day on your treatment day, and on the day before and after treatment.

How many Onda Micro Coolwaves™ treatments will I need?

The recommended number of treatments to see long-lasting results is 4 sessions, although it is possible to have more than this if needed.

How often should I have my Onda Micro Coolwaves™ treatments?

At illumia Therapeutics, we recommend Onda Micro Coolwaves™ treatments according to each individual's concerns and their goals. To get a detailed assessment of the treatment course best suited for you, it is best to make an appointment with our experts for an in-depth consultation. 

When will I see results?

For some patients, results are visible from the 1st session. However, it is more common to start seeing results after the 2nd or 3rd session.
