How does ONDA Coolwaves work?

Crafted in Italy by DEKA and popular in Korea, ONDA is the first and only device to use Coolwaves® — 2.45 GHz microwaves delivered through smart handpieces. The energy passes through the skin and is selectively absorbed by water-rich fat tissue underneath, where controlled heat breaks down fat cells. Your body then clears the released fat naturally through the lymphatic system over the weeks that follow.

The same controlled heat remodels the fibrous bands that cause cellulite dimpling and stimulates new collagen in the skin — which is why one ONDA treatment can reduce fat, smooth cellulite, and tighten skin at the same time. An integrated cooling system chills the skin surface throughout, protecting it while the energy works underneath.

• ✓Targets fat, cellulite & skin laxity in one treatment
• ✓Two handpieces: Deep for stubborn fat, Shallow for tightening, surface cellulite, and the chin area
• ✓Safe for all skin types
• ✓Non-invasive & comfortable — most patients describe a warm massage sensation
• ✓Zero downtime — walk in, walk out, get back to life

See what's happening under your skin

ONDA doesn't freeze fat or break it up mechanically. It uses heat — and the reason that works comes down to what the temperature increase does to a fat cell. Here is the sequence, stage by stage.

01

Before treatment

Healthy fat cells — adipocytes — sit packed together in the layer beneath your skin, separated by fibrous walls called septa. In stubborn areas these cells are enlarged and the septa are tight, which is what creates both the bulge and the dimpling of cellulite.

02

During and just after treatment

ONDA's Coolwaves — microwaves at 2.45 GHz — pass through the skin and are absorbed selectively by fat, which heats faster than the tissue around it. The stressed adipocytes push their lipid contents outward against the cell wall, forming bubble-like blebs. That pressure is enough to rupture the membrane, and the cell is irreversibly injured. Meanwhile the surface of your skin is actively cooled, which is why the treatment stays comfortable.

03

Over the following weeks

Your immune system finishes the job. Macrophages — the clean-up cells that arrive whenever tissue is damaged — surround the ruptured adipocytes and digest the released lipid and cellular debris. That material is carried away through your lymphatic system and metabolized normally, which is why results appear gradually over weeks rather than immediately. The heat also remodels the collagen in those fibrous septa, which is what smooths cellulite rather than only shrinking fat.

Mechanism described per the Onda Coolwaves International Advisory Board consensus (Bioengineering, 2024;11(12):1249) and an immunohistochemical study of microwave-treated abdominal adipose tissue (Cosmetics, 2025;12(2):42), in which ruptured adipocyte membranes showed loss of perilipin-1 and were surrounded by CD68-positive macrophages. Individual results vary.

What areas can ONDA treat?

ONDA treats the areas where diet and exercise tend to fall short:

• ✓Abdomen (stomach)
• ✓Flanks (love handles)
• ✓Hips
• ✓Buttocks
• ✓Thighs & legs
• ✓Bra fat & back
• ✓Knees
• ✓Arms
• ✓Under the chin (double chin / submental)

How many sessions will I need, and when will I see results?

Most patients need 3–4 sessions — the average complete protocol is four sessions per area, one every 4 weeks, with each visit taking about 30–60 minutes per treatment area. Because your body clears the treated fat through the lymphatic system, results build gradually over weeks to months — you'll typically see the change continue to improve well after your final session. We schedule a follow-up about one month after you finish to assess your results.

Does ONDA tighten skin, or only reduce fat?

Both. The same Coolwaves heat that breaks down fat also stimulates new collagen in the skin above it, so the area firms as it reduces. The Shallow handpiece is the one built for this. Outside the U.S. the treatment is often marketed as ONDA lifting for that reason — in Korea and Europe the firming effect is the headline rather than the fat reduction.

Can ONDA treat a double chin?

Yes. The submental area — under the chin — is treated with the Shallow handpiece and priced at $299 per session rather than the $599 body rate, both seasonal prices through September 7. Most patients plan for the same four-session protocol, spaced one every four weeks, and results build gradually as your body clears the treated fat.

The same session works on the fat and the skin firmness together. What that means for your chin specifically is something we assess in person.

ONDA vs. CoolSculpting

Both are non-invasive body contouring, but they work in opposite ways — and treat a different range of concerns:

How much does ONDA cost in Anaheim?

ONDA is priced per session, per treatment area:

These are seasonal prices, good through September 7 — or take your 3rd treatment free instead, whichever suits your package better. Most patients plan for the average four-session protocol per area. We'll quote your exact package at your consultation.

Safety, side effects & medical oversight

ONDA is an FDA 510(k)-cleared device, cleared in the U.S. as the DEKA TIAC II (K211091) for heating tissue to temporarily relieve pain and muscle spasms and increase local circulation, and for a temporary reduction in the appearance of cellulite. That is a device clearance, not a drug approval, and treating localized fat or skin laxity with it is an off-label use. At Neoderma, treatments are performed by licensed medical providers trained and approved by Sal Nadkarni, DO, and your medical history is reviewed before any treatment. Temporary redness or warmth in the treated area is common and resolves quickly. Rare potential adverse effects include blistering, bruising, temporary numbness or altered sensation, and contour irregularity — we review all of this with you at your consultation. ONDA is not appropriate during pregnancy or breastfeeding, or for patients with implanted cardiac devices or electronic stimulators, recent malignancy, severe vascular or clotting disorders, or uncontrolled diabetes.
