About Non-Surgical Fat Reduction, Cellulite & Skin Tightening.

Read more about Non-Surgical Fat Reduction, Cellulite & Skin Tightening Treatment details and clinical context

ONDA is a non-invasive energy-based device that delivers 2.45 GHz microwaves through cooled handpieces for localised adiposity, cellulite and skin laxity. Manufacturer information and small clinical studies report improvements in selected patients, but response varies; treatment is not painless or risk-free and is not a treatment for general weight loss.

Coolwaves are delivered to subcutaneous tissue using a selected handpiece and individual settings with surface cooling. Proposed effects include heating adipose and connective tissue. This does not mean every treated fat cell is completely removed or that comfort is assured; the operator must monitor tissue temperature and patient feedback.

Microwave treatment may reduce the appearance of cellulite or improve skin laxity in selected areas. Published studies are generally small and use defined protocols; complete disappearance of an orange-peel appearance is not guaranteed, and longer-term safety and effectiveness evidence remains limited.

Your clinician will confirm suitability, alternatives, material risks and the most appropriate treatment plan before you decide.

What to expect

Before, during and after your treatment.

Your exact experience and recovery are individual. Your clinician will explain what applies to you.

01 · Before How Do I prepare for this procedure?

Follow the instructions for the exact device and treatment area. International expert recommendations advise stopping moisturising or softening creams and gels on the area about one day before treatment and suggest around 2 litres of water daily only where medically appropriate. Tell the clinician about illnesses, medicines, implants, surgery and any fluid restriction.

02 · During What should I expect during the Consultation?

At Dr Sknn, during the consultation a medical history including a physical examination will be performed, measurements and photographs will also be taken. During the consultation there will be an opportunity to discuss any concerns, expectations, results or questions you may have. Prior to the treatment any post treatment advice and risks associated with the treatment are discussed ensuring you fully understand them and a consent form is signed.

03 · After Is there any downtime following Treatment?

Recovery varies. Temporary warmth, redness, tenderness, swelling, firmness, numbness, bruising or nodules can occur, and burns or blisters are possible. Follow the instructions and warning signs supplied by the clinic, and contact the clinic promptly about severe, worsening or persistent symptoms.

Treatment information and questions

Consider the specific concern, realistic limits and the actual proposal.

What ONDA uses

ONDA uses 2.45 GHz microwave energy delivered through cooled handpieces. The proposed treatment depends on the exact device, applicator, area and individual assessment.

Three different cosmetic concerns

Localised fat, cellulite and skin laxity are different concerns. Discuss which is relevant to you and what the proposed course may realistically change. This is not a treatment for general weight loss.

What the evidence can tell you

Published studies report changes in selected groups using defined courses and follow-up. Their results cannot predict your individual outcome or establish that every area or device configuration is suitable.

Plan treatment around the individual

Confirm the intended area, exact applicator, practitioner, course, review and total price. Device instructions and your assessment determine the plan; a list of body areas is not confirmation that each is suitable or currently offered.

Skin tightening and expectations

The degree of any tightening varies. No treatment course promises complete smoothing, removal of all loose skin or a surgical result. Discuss alternatives and the option of no treatment.

Risks, recovery and aftercare

Possible effects include itching, numbness, hardness, warmth, tenderness, redness, swelling, bruising, nodules, burns or blisters. More serious tissue injury or contour irregularity can occur, particularly with unsuitable selection or parameters. Follow the clinic's aftercare and contact it promptly about severe, worsening or persistent effects.

Recovery varies. Temporary warmth, redness, tenderness, swelling, firmness, numbness, bruising or nodules can occur, and burns or blisters are possible. Follow the instructions and warning signs supplied by the clinic, and contact the clinic promptly about severe, worsening or persistent symptoms.

Questions before booking

Frequently asked questions.

Preparation, treatment, recovery, suitability and aftercare guidance to support your consultation.

What are Coolwaves™?
ONDA uses 2.45 GHz microwaves delivered through deep or shallow cooled handpieces selected for the target tissue and area. The manufacturer describes applications for localised adiposity, cellulite and skin laxity. The evidence reviewed does not establish that ONDA is universally safer, more effective or less complicated than radiofrequency or cryolipolysis.
What should I expect during the Consultation?
At Dr Sknn, during the consultation a medical history including a physical examination will be performed, measurements and photographs will also be taken. During the consultation there will be an opportunity to discuss any concerns, expectations, results or questions you may have. Prior to the treatment any post treatment advice and risks associated with the treatment are discussed ensuring you fully understand them and a consent form is signed.
Can I have the Treatment Immediately?
Treatment should not be assumed to be suitable or available immediately. An appropriate clinician must review the treatment area, medical history, medicines, implants, previous procedures, risks, alternatives and the exact device protocol before consent; assessment may result in delay, an alternative or no treatment.
How Do I prepare for this procedure?
Follow the instructions for the exact device and treatment area. International expert recommendations advise stopping moisturising or softening creams and gels on the area about one day before treatment and suggest around 2 litres of water daily only where medically appropriate. Tell the clinician about illnesses, medicines, implants, surgery and any fluid restriction.
What is the after care advice?
Possible effects include itching, numbness, hardness, warmth, tenderness, redness, swelling, bruising, nodules, burns or blisters. More serious tissue injury or contour irregularity can occur, particularly with unsuitable selection or parameters. Follow the clinic's aftercare and contact it promptly about severe, worsening or persistent effects.
What are the interval in between sessions?
Treatment intervals are not universal. Published ONDA studies have used different schedules, commonly three or four sessions around three to four weeks apart, while expert recommendations say not to treat the same area again for at least 15 days. The exact interval must follow the device protocol and your clinical response.
Can the minimum interval between sessions be shortened?
Do not shorten an agreed interval without clinical review. Timing depends on the exact applicator and settings, treatment area, tissue response and current device guidance; it should not be justified by an unsupported claim about removing 'lysate'.
Is there any downtime following Treatment?
Recovery varies. Temporary warmth, redness, tenderness, swelling, firmness, numbness, bruising or nodules can occur, and burns or blisters are possible. Follow the instructions and warning signs supplied by the clinic, and contact the clinic promptly about severe, worsening or persistent symptoms.
What Treatment Regimes are required for most effective results?
There is no universal course that guarantees the most effective or long-lasting result. Small published studies have used three or four sessions with defined follow-up, and expert recommendations individualise the number of sessions and any drainage massage. Your plan should be based on the exact device, area, baseline findings and response.
How long does the treatment take?
Session length and the number of areas depend on the chosen handpiece, settings, tissue thickness and clinical plan. Expert recommendations divide treatment into 15 × 15 cm areas and advise no more than six such areas in one session, but this does not guarantee a 15-minute treatment or suitability for multiple areas.
Is the Treatment Painful?
ONDA treatment produces subcutaneous heating and can cause warmth, tingling, pain or discomfort. Integrated cooling and adjusted settings are used to manage surface temperature and tolerance, but treatment cannot be described as virtually pain-free and no broad comfort comparison with other technologies is established here.
Who Can Have Non-Surgical Fat Removal, Cellulite Reduction & Skin Tightening?
Being an adult is not enough to establish suitability. The clinician must review health conditions, medicines, implants, previous surgery or treatments, skin and vascular findings, tissue thickness, the treatment area and expectations against the exact device guidance before deciding whether treatment is appropriate.
Who Can’t Have Non-Surgical Fat Removal, Cellulite Reduction & Skin Tightening?
Important exclusions can include heart failure or cardiac implants, current or recent malignancy, severe vascular or clotting disease, pregnancy or breastfeeding, significant kidney or liver dysfunction, decompensated diabetes, relevant implants, active skin disease or wounds, reduced heat sensation and unsuitable anatomical areas. This is not a complete list; the exact device guidance and individual assessment control the decision.
Are there any side effects?
Suitability requires a complete medical and treatment-area assessment. The clinician should check the exact device guidance for absolute and relative contraindications, medicines, implants, vascular or skin findings, tissue thickness and excluded anatomical zones; this page cannot provide a complete screening list.
Which areas can be treated?
The manufacturer's product information illustrates selected uses including areas such as the abdomen, knees, hips, buttocks, underarms and the submental area, with different handpieces for different depths. Many anatomical zones must be excluded, so the practitioner must confirm that the exact area and applicator are appropriate before treatment.
How soon can I see results?
The timing and degree of any change vary. Small studies have reported group-level improvements after defined courses and follow-up, but they do not support a promise of a good result after one session or a universal number of sessions for fat, cellulite or tightening. Baseline tissue, area, settings and follow-up all affect interpretation.
What Does the Treatment Feel Like?
Coolwaves use 2.45 GHz microwave energy with handpieces designed to concentrate heating at selected depths and integrated cooling to protect superficial tissue. Energy delivery is not literally confined only to the intended tissue, so coupling, movement, settings, temperature and patient feedback must be monitored.
What should I expect straight after the treatment?
Temporary warmth, redness, tenderness, swelling, firmness, numbness, bruising or nodules may occur after body treatment. Increased urination is not evidence that triglycerides or destroyed fat cells are being passed into the urinary system. Follow the supplied aftercare and contact the clinic about severe, worsening or persistent symptoms.
