Hello! This is Seye Clinic, embracing all the beauty in the world.
The main difference between Ultherapy(often called Ulthera) and Ultherapy Prime lies in Prime’s advanced DeepSEE real-time ultrasound visualization, which enables more precise and personalized energy delivery at the 1.5mm, 3.0mm, and 4.5mm skin layers.
At Seye Clinic in Gangnam, both are performed with 300 or 600 shots per session, offering noticeable facial contour improvement in about 1–2 months with little to no downtime.
In our daily practice, we often meet patients who mention that, despite plenty of rest, their faces still appear tired, lax, or less defined. This is typically due to skin laxity—a gradual loss of elasticity and collagen, which can cause the jawline to sag, jowls to form, brows to droop, and neck bands to appear. For some, this process starts in their 30s, while for others, it’s more prominent later on.
Skin laxity is the process where the skin loses its firmness and ability to "bounce back", making features less sharp. This is driven by collagen depletion, sun exposure, genetics, and repeated facial movement. When mild to moderate, it is often addressed with non-surgical treatments like HIFU (High-Intensity Focused Ultrasound).
Ultherapy is a HIFU lifting method that focuses ultrasound energy at specific layers: the superficial dermis (1.5mm), deep dermis (3.0mm), and especially the SMAS fascia (4.5mm)—the same tissue lifted in surgical facelifts. By targeting these layers, it triggers the skin’s own repair response and new collagen production, gradually lifting and defining facial contours.
One trend we’ve noticed at Seye Clinic is that younger patients ask about preventative tightening (before sagging becomes profound), while others hope for one efficient session with lasting results and minimal downtime.

It's a frequent question: "Is there any real difference between Ultherapy and Ultherapy Prime?" Both use HIFU to induce lifting, but Ultherapy Prime represents a technological evolution.
Here’s how they compare at Seye Clinic (Gangnam, Seoul):
Ultherapy (Ulthera/Ultherapy) | Ultherapy Prime | |
|---|---|---|
Manufacturer | Merz (original) | Merz (latest generation) |
Approvals | FDA & MFDS | FDA & MFDS |
Key Technology | HIFU to 1.5/3.0/4.5mm layers | HIFU with DeepSEE real-time visualization (up to 8mm) |
Layer Targeting | Operator-skill dependent | Operator can use live ultrasound to see actual patient anatomy, customizing energy delivery per layer |
Session Shots | 300 or 600 shots | 300 or 600 shots |
Treatment Areas | Same | Same |
Skin Thickness Adaptation | Standard protocols | Tailored by imaging—adjusted for actual skin thickness and structure for safer, more effective results |
Device Authentication | Possible risk of fake tips | Merz NFC digital chip for genuine tip verification, preventing counterfeit use |
Duration of Effect | 6–12 months | 6–12 months |
Downtime | 0–3 days | 0–3 days |
Both treatments at Seye Clinic deliver energy only at the 300 or 600 shots level—never higher or lower—to ensure safety and efficacy.
Major benefits of Ultherapy Prime:
Are there limitations? Neither device can match surgical facelifts for severe sagging, and both require a stable collagen base for optimal lifting. For those with excessive volume loss or severe wrinkling, a combination approach (e.g., with fillers or skin boosters) may be required.
Patients often ask, “Does Ultherapy Prime hurt more? Will I need to hide at home? How long until I see results?” Our honest perspective:
In our clinical experience, those who benefit most from Ultherapy Prime are first-timers wanting the latest verified technology, or patients with uniquely thin or thick skin, who gain from the real-time visualization.
Medical tourists often ask why Gangnam, Seoul stands out for non-surgical lifting. In reality, the concentration of technology-forward clinics and highly experienced doctors means procedures like Ultherapy Prime are both more widely available and held to a higher standard, especially for international visitors who value verified safety and communication.
Seye Clinic is a 1-minute walk from Gangnam Station—making it highly accessible for both local patients and travelers. Our lead doctors are recognized KOLs (Key Opinion Leaders) for non-surgical aesthetics, and our clinic is Ulthera Official NFC Tip Certified. This means every session uses genuine, authenticated Merz handpieces—digitally verified with an NFC tag. For our patients, this eliminates any worry about counterfeit or reused tips—a growing concern seen throughout Korea’s aesthetic industry.
One detail only a practitioner truly sees: When using Ultherapy Prime’s DeepSEE screen, we often notice anatomical variations even within the same face—say, thicker cheek SMAS versus thinner temporal fascia. This lets us adapt shot placement in real-time, avoiding nerves and sensitive tissue more precisely, hence reducing discomfort and unwanted swelling.
Our modern, cool gray and white clinic interior puts international visitors at ease, reflecting the advanced, unpretentious approach we bring to every procedure.

At Seye Clinic, every lifting treatment starts with a thorough, personalized consultation. Our doctor assesses facial contour and skin thickness using visual inspection and touch, then explains how Ultherapy Prime or classic Ultherapy can help. If proceeding with Prime, the digital NFC chip is scanned for device authentication right before your eyes, underscoring device safety.
Next, we mark targeted vectors for lifting, cleanse the skin, and apply topical numbing. Using the DeepSEE live ultrasound imaging, we visualize the patient’s unique anatomy and carefully place energy only at the prescribed 300 or 600 shots—never more, never less. Post-treatment, we review aftercare, and patients can usually resume normal activities right away.
Our approach is grounded in education, transparency, and international service—from gentle touch to English support throughout, and a commitment to technology only a true Key Clinic can provide.
Q: Which is better: Ultherapy or Ultherapy Prime?
Both deliver HIFU lifting at 300 or 600 shots, but Ultherapy Prime offers real-time imaging for precise targeting and device verification with the NFC tag. At Seye Clinic, international patients often prefer Prime for these reasons.
Q: How many shots do I need for Ultherapy or Ultherapy Prime?
At Seye Clinic, treatments are standardized to 300 or 600 shots per session, depending on facial area and degree of skin laxity. We do not offer customized shot numbers outside this safe, proven range.
Q: How long does the effect of Ultherapy Prime last?
Results typically last 6–12 months. Most patients notice progressive tightening and lifting over the first 1–2 months post-procedure, then maintain results up to a year before considering a repeat session.
Q: Is there downtime or visible marks after Ultherapy Prime?
Most patients experience little to no downtime—some redness or swelling may persist for up to 3 days, but you can return to work or sightseeing in Gangnam quickly. Bruising is rare with proper technique and DeepSEE guidance.
