Hello! This is Seye Clinic, embracing all the beauty in the world.
For Onda Lifting (Coolwaves face tightening and jawline contour), we typically recommend 3–4 sessions spaced 4 weeks apart. Each treatment uses precision energy (40–80kJ) to sculpt and firm, with visible improvements often beginning immediately and best seen at about 1 month post-procedure.
There’s zero downtime, making this a practical option even for busy schedules.
One scenario we encounter nearly every day: a patient looks in the mirror and notices their jawline is less defined, or an emerging double chin catching the light in video calls. These changes aren't just about age—they’re influenced by genetics, weight fluctuations, and skin quality.
Jawline definition loss is a gradual process. The lower face contour softens as collagen decreases, skin begins to sag, and even small fat accumulations under the chin become more prominent. In medical terms, this is submental fat and mild skin laxity. Unlike severe sagging that may require surgery, these early changes are ideal for non-surgical energy-based solutions like Onda Coolwaves.
Onda uses microwave energy (not ultrasound or laser) to target the skin at two depths:
So, Onda is more than a “lifting” device—in a single session, it can both reduce unwanted fat and tighten the skin. We often see those who “just want something effective” but don’t want visible bruising, swelling, or recovery—a scenario perfectly matched to Onda's strengths.
Zero downtime means you can schedule a session during a lunch break, with no marks or bruising. If your concern is subtle jawline sagging or double chin, yet you want to avoid surgery or liposuction, Onda might be exactly what’s needed.

Patients often ask, “How often do I need to repeat Onda? How does it compare to HIFU or RF lifting?” Here’s a clear breakdown of how Onda’s schedule and effects stack up:
Treatment | Mechanism | Sessions Needed | Interval | Recovery/Downtime | Effects Visible |
|---|---|---|---|---|---|
**Onda Coolwaves** | *Microwave energy* | **3–4** | **4 weeks** | **0 days** | Immediate, best in 1mo |
HIFU (ex: Ultera, Shurink) | Focused ultrasound | 1–2 | 6–12 months | Mild swelling | Gradual (2–3mo) |
RF Lifting | Bipolar/monopolar RF | 3–5 | 2–4 weeks | Possible redness | Weeks |
Threads | Absorbable suture lift | 1 | 12–18 months | 3–7 days bruising | Immediate |
Injectable Lipolysis | Deoxycholate or PPC | 2–5 | 2–3 weeks | Swelling, bruising | 2–4 weeks |

After performing many Onda treatments, one pattern we notice is how surprised patients are by the lack of downtime. Here’s what to expect at each stage:
Your experience can be personalized—Onda’s kJ-based dosing (40, 60, 80kJ) lets us tailor intensity and coverage exactly for your anatomy and goals.
Why do so many international visitors seek out Onda lifting in Gangnam, Seoul? This area is globally renowned for advanced yet natural-looking non-surgical treatments, clinical transparency, and skillful execution.
At Seye Clinic, a one-minute walk from Gangnam Station, we’ve invested in the latest DEKA Onda Coolwaves platform and meticulously adhere to international safety guidelines (MFDS, FDA, CE approved) for peace of mind. Our approach is distinct:
As an official Alltite Research Advisory Hospital and a KOL doctor-led facility, we share knowledge not only with patients, but also regionally as clinical speakers. It is not uncommon for overseas doctors to visit just to observe our energy-planning methods.
Another detail only a Seye practitioner would know: Onda’s contact cooling is expertly calibrated to the patient’s baseline skin temperature prior to each session—this minimizes post-procedure redness more effectively than default “factory” settings.

What can you expect at Seye Clinic for your Onda Lifting journey? Here’s how we proceed:
1. Assessment & Planning: One of our international coordinators will record your concerns, photos, and goals. Your data is reviewed by our KOL doctor, who determines whether you’re best suited for Onda (and which depth/energy plan within 40–80kJ). 2. Custom Protocol Design: Based on your face shape and fat distribution, we select the ideal combination of 3mm (for skin tightening) and 7mm (for fat reduction) handpieces. 3. Comfort Optimization: We apply topical anesthetic and recalibrate Onda’s cooling to your unique skin temperature. If requested, additional cooling or sleep sedation options are available. 4. Doctor-Performed Procedure: Our KOL doctor performs the treatment, applying energy steadily to ensure the skin is sculpted without overheating. 5. Immediate Check: Afterward, you can inspect the visible improvement, receive tailored aftercare guidelines, and return to daily life with no restrictions.
Seye’s unique approach—personalized dosing, cooling calibration, and hands-on KOL physician involvement—ensures your experience is both safe and clinically optimized.
Q: How many Onda Lifting sessions do I need for my jawline? Most patients benefit from 3–4 Onda sessions spaced about 4 weeks apart for optimal results in lower face and double chin contouring.
Q: What is the standard interval between Onda Lifting sessions? Onda sessions are typically scheduled every 4 weeks, allowing the skin and fat to respond and remodel effectively before the next procedure.
Q: Is there any downtime or visible mark after Onda Lifting? One of Onda's main advantages is zero downtime—patients can return immediately to work or social life, as there is no bruising or swelling post-treatment.
Q: How much energy is used per Onda session at Seye Clinic? We apply either 40, 60, or 80kJ per session, tailoring the energy to your face size and treatment needs for effective contour refinement.
