How it works

Microwave technology, working beneath the surface

ONDA PRO uses Coolwaves®, a patented form of microwave energy, to deliver controlled heat beneath the skin. Its energy interacts with fat and connective tissue, while continuous contact cooling helps protect the skin’s surface and manage discomfort.

The handpiece glides over the treatment area. You may feel warmth building beneath the skin, with the surface kept cool during treatment.

One technology, three concerns

  • Localised fat: Controlled energy can disrupt targeted fat cells. The body gradually processes and clears the affected cells over time.
  • Cellulite: Treatment acts on fat and the fibrous connective tissue involved in dimpling, helping improve the skin’s appearance.
  • Skin laxity: Heating can contract existing collagen fibres and stimulate collagen renewal, supporting firmer-looking skin.

Three handpieces for different depths

ONDA PRO’s Pocket, Shallow and Deep handpieces let us select the treatment approach according to the tissue and concern.

Pocket — Designed for smaller, more precise areas, including suitable lower-face and under-chin concerns.

Shallow — Used for concerns closer to the surface, including cellulite and skin laxity.

Deep — Used to target localised fat in larger body areas.

Your clinician selects the handpiece and settings after assessing skin firmness, fat thickness and the surrounding anatomy.

What it treats

Localised fat pockets

ONDA PRO can address selected pockets of fat on areas such as the abdomen, flanks and thighs. It is a contouring treatment for specific areas rather than a treatment for overall weight loss.

Cellulite & uneven body texture

Treatment can soften the appearance of dimpling, particularly around areas such as the thighs and buttocks. We assess whether cellulite, laxity or a combination is contributing to the uneven texture.

Body skin firmness

Mild to moderate laxity can make skin look less firm around areas such as the abdomen and upper arms. ONDA PRO may help improve firmness where the degree of laxity is suitable for non-invasive treatment.

Lower face & under-chin definition

Selected protocols can address skin firmness and localised fullness around the lower face and beneath the chin. We assess whether your concern comes from loose skin, fat or volume loss before recommending treatment.

Sessions & results

How many treatments you’ll need

Typically, a course of 2–3 treatments is recommended, although some clients may need a different number. We review your response before recommending additional sessions.

How appointments are spaced

Sessions are generally spaced around 3–5 weeks apart, depending on the area and treatment approach.

When results appear

Some clients notice an early change after one session. Fat reduction and collagen remodelling develop gradually, so an immediate change does not represent the final result.

We assess progress across your course and afterwards, allowing time for the tissue response to develop.

Maintaining your results

Stable weight and consistent healthy habits help support your body-contouring result. Maintenance may be recommended for ongoing concerns such as skin laxity or cellulite.

Prep & aftercare

Before your appointment

Stay well hydrated and follow our instructions on avoiding moisturiser on the treatment area beforehand.

Tell us about your medical history, medications, implanted devices and previous procedures in the area so we can assess suitability.

What recovery may look like

Most clients can return to everyday activities after treatment. Temporary warmth, redness, tenderness or swelling may occur. We’ll explain what to expect for your treatment area.

Caring for the area

  • Maintain your usual hydration.
  • Massage the area only as directed by your provider.
  • Gentle movement, such as walking, is generally appropriate.
  • Avoid strenuous exercise for at least 48 hours, unless advised otherwise.
  • Avoid alcohol for 3–4 days after treatment.
  • Protect the area from direct sun and use sunscreen on exposed skin.

When to contact us

Contact our team if you develop persistent burning, blisters, worsening pain, increasing swelling or unexpected skin changes.

FAQs

Frequently asked questions

Is ONDA PRO a laser?

No. It uses microwave energy called Coolwaves®. This is a different energy source from laser, radiofrequency or ultrasound treatments.

Does treatment hurt?

You may feel a deep warming sensation as the handpiece moves over your skin. Some people compare it to a hot stone massage. Integrated cooling helps manage surface heat, but comfort varies. Tell your provider if the sensation becomes uncomfortable.

Can it tighten skin without reducing facial fat?

Treatment can be planned with skin firmness as the main goal. We select the handpiece, settings and area carefully, considering where facial volume should be preserved. This does not make unwanted fat loss impossible, so assessment matters.

Will I lose weight?

ONDA PRO targets localised contours. It does not replace medical weight management or produce the same result as overall weight loss.

How is it different from CoolSculpting?

ONDA PRO uses controlled microwave heating, while CoolSculpting uses controlled cooling to affect fat cells. ONDA PRO also offers protocols addressing cellulite and skin firmness. Suitability depends on your anatomy and goals.

Is it suitable for skin of colour?

ONDA PRO may suit a wide range of skin tones. We still assess your skin, medical history and treatment area before recommending it.

Who might need a different treatment?

Significant loose skin, larger fat deposits or concerns caused mainly by volume loss may need another approach. Pregnancy, implanted devices and certain medical conditions can also affect suitability.

Bring your concern, not a treatment name.
