Cartessa Aesthetics’ late‑April 2026 launch of ONDA PRO by DEKA marks the first broad commercial entry of this re‑engineered Coolwaves® platform into the United States and Canadian markets. The system brings a next‑generation 2.45 GHz microwave platform with three handpieces—Deep, Shallow, and the new Pocket applicator—designed to target fat, cellulite, and lifting‑focused areas with greater selectivity and comfort. For North American clinics, this release positions ONDA PRO as a consumable‑free, non‑invasive body‑and‑face contouring solution that competes directly with technologies such as CoolSculpting.

DEKA ONDA Pro vs CoolSculpting: Which Fat Reduction Treatment Is Better?

What Is ONDA PRO by DEKA and How Does It Work?

ONDA PRO by DEKA is a non‑invasive aesthetic platform powered by an upgraded 2.45 GHz Coolwaves® microwave technology engineered to bypass the epidermis and selectively heat subcutaneous fat and connective tissue. This frequency is absorbed more efficiently by fat cells than by skin, allowing controlled thermal injury to fat while keeping the skin surface at a comfortable temperature.

The system uses three handpieces—Deep, Shallow, and Pocket—each tuned for specific depths and indications, from deeper fat reduction to superficial tightening and lifting. Because the platform relies on microwaves rather than cryolipolysis or suction, ONDA PRO offers a consumable‑free, chair‑time‑efficient workflow: no suction‑cups, no consumable pads, and no need for repeated applicator replacement.

Why Is the North American Market Launch Significant for Clinics?

Cartessa Aesthetics’ official U.S. and Canadian rollout of ONDA PRO creates a clear commercial pathway for North American practices to access this EU‑validated Coolwaves® platform for the first time at scale. Prior to 2026, ONDA‑based treatments were largely available through international or limited‑market channels; the North American launch standardizes training, support, and service structures.

Clinicians now have a proven, FDA‑aligned body and face contouring option that addresses both fat reduction and skin tightening in a single modality, which can differentiate their offering from providers relying only on cryolipolysis‑based systems. From a revenue‑cycle perspective, a consumable‑free device with high‑ticket‑per‑session potential can also improve cash flow and reduce overhead versus high‑consumable systems.


How Does the Pocket Handpiece Change Treatment Options?

The new Pocket handpiece is the first applicator in the ONDA PRO line explicitly designed for smaller, anatomically complex or “lifting‑focused” zones such as the submental region, lateral jawline, and petite periorbital or décolletage areas. It operates at a shallower yet precisely controlled depth, delivering Coolwaves® energy in a footprint optimized for contouring and lifting rather than bulk fat reduction.

This expands the platform beyond traditional “love‑handle” or “saddle‑bag” body treatments into high‑demand aesthetic niches where patients seek subtle lifting and definition without surgery. For clinics, the Pocket handpiece supports a “full‑face‑and‑body” narrative, allowing practitioners to market ONDA PRO as a single‑platform solution from jowl‑to‑thigh contouring, rather than a body‑only device.

Example Indications by Handpiece

Handpiece Target Depth Primary Indications
Deep Deeper subcutaneous fat Abdomen, flanks, thighs, back fat
Shallow Superficial fat and cellulite Inner thighs, arms, buttocks, cellulite‑prone zones
Pocket Very shallow, lifting‑focused Submental area, jawline, small face/neck zones, periorbital, décolletage*

How Does ONDA PRO Compare with CoolSculpting and Other Systems?

ONDA PRO and CoolSculpting differ fundamentally in mechanism: ONDA PRO uses 2.45 GHz microwave energy to heat and disrupt fat cells while stimulating collagen, whereas CoolSculpting relies on cryolipolysis to crystallize and destroy fat with controlled cooling. This contrast drives differences in patient experience, downtime, and secondary benefits such as skin tightening and cellulite smoothing.

Clinically, ONDA PRO tends to offer a warmer, massage‑like sensation with zero downtime versus CoolSculpting’s suction‑based cold‑pull feeling and potential for temporary numbness or bruising. Because ONDA PRO also targets connective tissue and collagen, practices can market fat‑plus‑tightening outcomes in one session, whereas CoolSculpting remains primarily fat‑focused with limited tightening effects.


What Does an ONDA PRO Treatment Feel Like and What Results to Expect?

Patients typically describe ONDA PRO sessions as a warm, deep‑tissue–style massage rather than a cold pull or intense burning. The system’s integrated continuous contact cooling maintains skin‑surface comfort, while the 2.45 GHz energy penetrates to the subcutaneous layer, generating controlled heat that patients often say is relaxing and tolerable without anesthesia.

Clinicians can expect measurable circumference reduction and contour refinement over several weeks as the body clears injured fat cells, with many patients reporting visible improvements in sagging or cellulite‑affected areas after a short series of sessions. Because ONDA PRO is non‑invasive and consumable‑free, it fits well into “lunchtime” or evening‑clinic workflows, making it easy to schedule without extended prep or recovery time.

How Can Clinics Integrate ONDA PRO into Their Workflow and Chair‑Day Planning?

Successful integration of ONDA PRO starts with a clear service‑map: defining which body and face zones will be treated with each handpiece (Deep, Shallow, Pocket) and embedding ONDA PRO into existing medical‑aesthetic packages alongside injectables, lasers, or RF‑based tightening treatments. Because the platform is consumable‑free, practices can reduce per‑session overhead and streamline consent, consent management, and inventory workflows versus high‑consumable systems.

Marketing should emphasize ONDA PRO’s dual‑action benefit: fat reduction plus skin tightening and cellulite smoothing, particularly in areas where CoolSculpting leaves skin laxity untreated. Clinics can further differentiate ONDA PRO by bundling treatment series with imaging, body‑composition analysis, and post‑care guidance, turning each session into a repeat‑visit revenue‑driver rather than a one‑off procedure. ALLWILL can support this integration by providing brand‑agnostic device‑evaluation services and maintenance‑ready units that align with a clinic’s procedural volume and budget.
