Sculpt Body Contouring in Chicago | BodyEstiq™ & OndaWaves
Non-Invasive Fat Reduction, Cellulite & Skin Tightening by a Board-Certified Dermatologist
There’s a particular kind of frustration that brings patients to Dr. Cheung for body contouring. They’re not looking to lose weight; they’ve already done that work. What they’re dealing with are the spots that didn’t get the memo: the lower belly that stays soft no matter what, the thigh cellulite that’s been there since their twenties, the arms or flanks that just won’t budge. These aren’t problems you can exercise your way out of. They’re structural, rooted in fat distribution, connective tissue, and skin quality that respond to biology more than effort.
Sculpt was designed for exactly this. Known as BodyEstiq™ in the US and OndaWaves or Onda Coolwaves® internationally, it uses microwave energy to reach the fat layer beneath the skin, reducing stubborn fat, restructuring the connective tissue that causes cellulite, and tightening skin, all in a single treatment with no surgery and no downtime.
At Cheung Aesthetics & Wellness in Willowbrook, Dr. Jessie Cheung brings a board-certified dermatologist’s understanding of skin and tissue to every Sculpt consultation. That means an honest assessment of what the technology can realistically accomplish for your specific anatomy and a treatment plan built around your actual goals, not a protocol that’s the same for everyone.
A Different Kind of Body Contouring Technology
Sculpt is built on Onda Coolwaves® technology, developed by DEKA, a medical device manufacturer with deep roots in laser and energy-based medicine. If you’ve encountered the name BodyEstiq™ while researching providers in the US, or come across OndaWaves and Onda Coolwaves® through international sources, you’re looking at the same device. Different names used by different distributors in different markets, with identical technology and clinical evidence behind all of them.
What distinguishes Sculpt from the radiofrequency and laser devices that dominate the body contouring market is a matter of physics. It operates at 2.45 GHz, a microwave frequency at which the skin’s upper layers are largely transparent. Rather than depositing energy in the dermis on the way down, approximately 80% of Sculpt’s energy passes through to the subcutaneous fat layer where it’s actually needed. Traditional RF devices can’t do this; they heat the dermis first, which limits how aggressively they can treat the fat without risking burns or discomfort at the surface.
This isn’t a marginal difference. It’s what allows Sculpt to produce the kind of fat reduction, cellulite improvement, and skin tightening that patients actually notice: not just on a measurement chart, but in how their clothes fit and how they feel about the areas they’ve been trying to change.
Three Results, One Treatment
Most body contouring devices do one thing reasonably well. Sculpt does three things simultaneously, which is genuinely unusual in this category.
Fat reduction: Microwave energy heats fat cells to a temperature that disrupts their membranes, triggering apoptosis (programmed cell death). The body clears those cells gradually through the lymphatic system in the weeks that follow. Because this is a heat-based process rather than freezing, there’s no risk of paradoxical adipose hyperplasia (PAH), the rare but serious CoolSculpting complication where treated fat enlarges rather than shrinking.
Cellulite smoothing: Cellulite is structural, not just cosmetic. The dimpled appearance comes from fibrous bands of connective tissue called septa that anchor the skin to underlying structures and pull it inward unevenly. Sculpt’s energy penetrates to those bands and softens them, releasing the tension that creates the dimpling. This is meaningfully different from devices that improve the surface appearance of cellulite without touching the underlying cause. The improvement is more durable because it addresses what’s actually happening beneath the skin.
Skin tightening: The portion of energy that interacts with the dermis triggers an immediate contraction of existing collagen fibers, followed by progressive new collagen production over the months that follow. Patients often find that the tightening effect continues to improve well after their treatment series is finished, a sign that the remodeling process is still working.
Where Sculpt Works Best
Sculpt can address virtually any area of the body below the shoulders, and Dr. Cheung adjusts the protocol based on the tissue characteristics of each specific area.
Abdomen: The abdomen is where most patients start, and for good reason. It’s also where the gap between what diet and exercise can accomplish and what body contouring can accomplish becomes most apparent. Sculpt’s deep energy delivery targets subcutaneous belly fat directly while working on skin laxity at the same time, which matters especially for patients after pregnancy or significant weight loss, where both issues tend to coexist.
Flanks and Love Handles: Flank fat is often hormonally influenced, which is part of why it’s so resistant to conventional approaches. Sculpt treats this area without the bruising, nerve sensitivity, or weeks of discomfort that patients frequently report with cryolipolysis, and without the treatment-area limitations that come with freeze-based devices.
Thighs: The thighs are among the most requested areas at Cheung Aesthetics, particularly among patients who have dealt with cellulite for years without finding anything that actually works. Because Sculpt addresses the fibrous septa structurally, the improvement here tends to be more meaningful and longer-lasting than what surface-level treatments produce. Fat reduction and skin tightening happen in the same session.
Buttocks: For patients who want to lift and firm the gluteal area without surgery or injectable fillers, Sculpt offers a genuinely non-invasive option. Posterior thigh cellulite can be addressed in the same treatment, which makes the session efficient for patients dealing with both concerns.
Upper Arms: Loose skin on the upper arms is one of the more difficult body concerns to address non-invasively, and a common frustration for patients who have lost weight and expected the skin to follow. Sculpt’s collagen stimulation is particularly relevant here because for many patients in this area, skin laxity is the primary issue, and the tightening effect addresses it in a way that fat reduction alone cannot.
Back and Bra Fat: Smaller, more localized areas like back rolls and bra fat are notoriously hard to target with most non-invasive devices. Sculpt’s quadrant-based approach allows precise treatment of these contained zones, which otherwise tend to get overlooked in body contouring conversations.
Above the Knee and Hips: Non-invasive options for these areas are genuinely limited. Sculpt is one of the few technologies with the depth and precision to meaningfully address fat and laxity above the knee, as well as the stubborn outer hip fat that accumulates in the trochanteric region and resists even significant overall weight loss.
What to Expect with Sculpt
Before your appointment, Dr. Cheung will conduct a full consultation: a real clinical assessment of your skin quality, tissue characteristics, and goals, not a sales conversation. She’ll tell you honestly whether Sculpt is the right approach, whether a combination of treatments would serve you better, and what realistic improvement looks like for your specific anatomy. One practical note: skip moisturizer on the treatment area the day before your session, since skin hydration can reduce the microwave energy’s ability to penetrate effectively to the fat layer.
During treatment, the handpiece is applied directly to the skin. Patients consistently describe the sensation as a warm, deep massage, similar to a hot stone treatment. The built-in cooling system keeps the surface comfortable throughout. Each area takes about 18-20 minutes, and multiple areas can be addressed in a single visit.
After treatment, there’s no downtime. You leave the way you came in. Some mild redness or warmth in the treated area is common and typically resolves within hours. To support the body’s clearance of treated fat cells, Dr. Cheung recommends staying well-hydrated and doing gentle self-massage in the treated area for the first two weeks after each session.
How Sculpt Compares to Other Options
Patients considering body contouring near Chicago typically weigh Sculpt against a few alternatives. Here’s how the differences actually matter in practice.
Sculpt vs. CoolSculpting: Both reduce fat non-invasively, but through opposite mechanisms: heat versus cold. The more meaningful distinctions are that Sculpt also addresses cellulite and skin tightening in the same treatment, and carries no risk of paradoxical adipose hyperplasia (PAH), the rare CoolSculpting complication where treated fat grows rather than shrinks. For patients who have heard cautionary stories about CoolSculpting outcomes, Sculpt is a more versatile and lower-risk alternative.
Sculpt vs. traditional RF: Radiofrequency devices tighten skin and can address mild fat, but they deposit most of their energy in the dermis rather than the fat layer, which limits how much fat reduction they can realistically produce. Sculpt’s microwave frequency bypasses this limitation. For patients whose primary concern is fat or cellulite rather than skin quality alone, the difference in energy depth matters considerably.
Sculpt vs. EMSculpt: EMSculpt builds muscle and can reduce some fat, targeting muscle definition rather than fat reduction or skin laxity. It’s a different category of treatment entirely. Some patients benefit from combining both, and Dr. Cheung can advise on whether that approach makes sense for your goals.
Is Sculpt Right For You?
Sculpt works best for patients who are at or near a stable, healthy weight and want to address specific areas of fat, cellulite, or skin laxity that haven’t responded to diet and exercise. It’s a refinement treatment that contours, smooths, and tightens, and patients who come in with that expectation tend to be the most satisfied with their results.
It’s not the right starting point for patients who are actively losing weight, since ongoing weight changes affect how results develop and how long they last. And it’s not appropriate for patients who are pregnant, have metal implants or pacemakers in the treatment area, or have active skin conditions at the treatment site.
If you’re not sure whether you’re a good candidate, that’s exactly what the consultation is for.
The Cheung Aesthetics Difference
Most body contouring is offered by med spas, where providers follow a standard protocol and the device largely drives the treatment. At Cheung Aesthetics & Wellness, the approach is different. Our practice is led by Dr. Jessie Cheung, a board-certified dermatologist who has spent her career understanding how skin and tissue behave, age, and respond to energy-based treatments — and that expertise informs everything we do.
That means consultations that go deeper than most. We assess the distribution and depth of fat in the areas you want to treat, evaluate skin quality and laxity, and consider how Sculpt’s mechanisms interact with your specific anatomy before recommending anything. We’ll also tell you when Sculpt isn’t the right answer — when a different technology, an injectable approach, or a combination strategy would produce a better result for what you’re actually dealing with.
