Hello! This is Seye Clinic, embracing all the beauty in the world.
Combining Onda Coolwaves and Ultherapy Prime at our Gangnam clinic allows you to benefit from both skin tightening and fat reduction, all with zero downtime. In our experience, patients see enhanced contouring and a firmer jawlineâoften with visible initial changes after just one session, and peak improvement at about one month.
A scenario we commonly encounter: a patient arrives saying, âEven with makeup and good sleep, my lower face still looks tired and undefined.â This is exactly the type of concern Onda and Ultherapy address.
Jawline sagging is the gradual loss of firmness along the lower face, often leading to a less defined contour and creation of jowls. The double chin refers to accumulation of submental fat under the chin, sometimes paired with loose skin, creating a âheavierâ profile in photos and real life.
Jawline sagging is a structural loss of support due to aging, sun, and gravity. Over time, the SMAS (Superficial Musculoaponeurotic System) and deeper connective tissues weaken, creating skin laxity and descent of facial volume. Fat compartments under the chin can also enlarge, emphasizing the double chin.
Addressing both fat and sagging requires a multi-layered approach. Treating only one often leaves a âflatâ or incomplete result. Patients who diet or exercise sometimes see persistent fullness in the jawline or chin because the structural layer and localized fat respond poorly to lifestyle changes alone.

After performing these treatments for years, we consistently find that the most natural, sculpted results emerge when skin tightening, fat reduction, and deep tissue lifting are layered thoughtfullyâwithout surgery or visible downtime.
A question that came up three times last week alone was: âShould I do Onda first for the double chin, or Ultherapy for a liftâor both?â Understanding the devicesâ strengths makes this much clearer:
Treatment | Energy Type | Target Depth(s) | Key Effect | Typical Dose at Seye | Downtime | Ideal For |
|---|---|---|---|---|---|---|
Onda Coolwaves | Microwave | 3mm (skin tightening), 7mm (fat reduction) | Fat reduction + firming | 40/60/80kJ per area | None | Double chin, jaw contour, mild laxity |
Ultherapy Prime | HIFU | 1.5/3/4.5mm (superficial to SMAS fascia) | Deep tissue lifting | 300 or 600 shots | 0-3 days | Skin laxity, sagging, lifting need |
Why combine them? Hereâs when that synergy shines:
Together, this layered approach provides both sculpting and rejuvenation, especially suited for those whose main concern is both sagging and âfullnessâ in the lower face.
⢠Limitations: If there is extreme skin laxity or significant bone loss, surgical lifting may be more appropriate. Onda is not for those with metal implants or current facial infections. Ultherapy should be avoided during pregnancy.
After treating many patients with these combinations, one pattern we notice is that people with âmixedâ concernsâsoft fullness and droopâsee more visible results when Onda and Ultherapyâs effects overlap.
In our clinical experience, patients are often most concerned about three things: cost, discomfort, and time away from work or daily life.
Longevity: After a course of Onda (3â4 sessions at 4-week intervals) and a single full-face Ultherapy, patients see maintained results for several months; Ultherapy lifting can last up to 12 months for some.
The core answer: Combining these two modalities at Seye achieves more dramatic and natural-looking lower face rejuvenation than either one aloneâwith practically no interruption to daily life.
Gangnam is known internationally as Seoulâs aesthetic hub, but among many choices, Seye Clinic stands out for its commitment to genuine technology and patient-centered care.
Our clinicâs modern, minimal interiorâcool gray and monochrome whiteâsets a tranquil, confidence-building tone from the moment you step in. Located just a 1-minute walk from Gangnam Station, we welcome visitors seeking clinical-grade results, efficiency, and authenticity.

One detail few realize: We routinely adjust our Ultherapy HIFU vector design to avoid flattening the midface volumeâpreserving healthy fullness, rather than chasing a âpulledâ or hollow look. This nuance, born of experience, ensures results are lifting yet never artificial.
Hereâs how your treatment unfolds at Seye Clinic:
1. Consultation: Our doctor discusses your unique contours, aesthetic goals, and any previous lifting/fat treatments. We examine skin tone, fat distribution, and tissue support. 2. Device Verification: For Ultherapy, the NFC authentication is performed in your presenceâensuring genuine, safe technology. 3. Treatment Planning: We select Ondaâs 3mm or 7mm handpiece based on whether your primary concern is surface laxity, submental fat, or both. Dose is selected from 40/60/80kJ per area. 4. Onda Session: This delivers controlled microwave energy, immediately firming the skin and melting pockets of fatâwhile cooling keeps the surface comfortable. 5. Ultherapy Prime Session: Ultrasound visualization precisely targets all tissue layers up to 4.5mm deep, with 300 or 600 shots depending on the degree of laxity. 6. Aftercare: Patients are advised on gentle skin care; most resume normal life instantly. No make-up ban is required.
Throughout, your comfort is maintained, with constant temperature monitoring for Onda and visual guidance for Ultherapyâhallmarks of Seyeâs process. Our care is both technology-forward and human, ensuring not just visible changes, but an experience that inspires trust and satisfaction.
Q: What makes combining Onda and Ultherapy better than doing just one?
The synergy arises from layering strengths: Ondaâs 40/60/80kJ microwaves break down fat and tighten skin, while Ultherapyâs HIFU delivers a deep, lasting lift. Together, this multiplies the tightening, slimming, and lifting effects beyond what either provides alone.
Q: How soon will I see results after the Onda + Ultherapy protocol?
With Onda, some tightening and contouring are visible right away, but optimal results appear around 1 month. Ultherapyâs lifting gradually becomes obvious over 1â2 months, so the combination effect evolves naturally.
Q: Is there any downtime or aftercare I should know about?
Onda has zero downtimeâjust mild redness or warmth that subsides within hours. Ultherapy may cause swelling or redness lasting up to 3 days. At Seye Clinic, most patients return to work the same day after either procedure.
Q: How do I know the Ultherapy device is authentic?
Seye Clinic is an Ulthera Official NFC Tip Certified Clinic. Each Ultherapy Prime procedure includes a digital NFC tag check for verification, ensuring your treatment is genuine and safe.
