Ultherapy PRIME

Ultherapy PRIME in Seoul

Medically reviewed by Dr. Chae-ho Lee, Medical Director, Doctorpetit Clinic Hongdae; Member, Korean Society of Aesthetic Plastic Laser Medicine

Doctor profile · Doctorpetit Clinic Hongdae, Seoul

Ultherapy PRIME in Seoul is a non-surgical lifting treatment that sends micro-focused ultrasound energy to deep structural layers of the skin, including the SMAS, to tighten sagging tissue and prompt the body to make new collagen. What sets this generation apart is DeepSEE real-time imaging, which lets the doctor see the tissue layers on screen while placing each line of energy. At Doctorpetit Clinic Hongdae, patients are assessed and treated by the Medical Director, Dr. Chae-ho Lee, in a single short visit.

What Is Ultherapy PRIME?

Ultherapy PRIME is the current generation of the Ulthera System, a micro-focused ultrasound (MFU) device that heats precise points beneath the skin surface to lift and firm lax tissue on the face and neck without incisions, needles, or downtime.

• Focused heat below the surface. Ultrasound energy converges at a set depth under the skin and creates tiny points of thermal coagulation, while the skin surface itself is left intact.
• Three treatment depths. The clinic uses 1.5 mm, 3.0 mm, and 4.5 mm transducers, so the doctor can work on shallower skin layers and on the deeper SMAS (superficial musculoaponeurotic system) that a surgical facelift also addresses.
• Seeing before treating. DeepSEE imaging displays the dermal and subdermal layers in real time, which helps the doctor confirm good skin contact and the right depth before each pass.
• Collagen does the rest. The heated points trigger a natural repair response. Some contraction is felt early, but the main lift builds gradually as new collagen forms over the following two to three months.
• Faster delivery than the legacy system. The newer system delivers energy faster, which the clinic notes helps reduce overall discomfort during the session.

In the United States, the Ulthera System holds FDA 510(k) clearance as a non-invasive dermatological aesthetic treatment to lift the eyebrow, lift lax tissue under the chin and on the neck, improve lines and wrinkles of the décolleté, and improve the appearance of skin laxity on the abdomen and arms. The February 2025 clearance that added the body areas names the UC-1 Control Unit PRIME as its predicate, and it states that the DeepSEE transducer allows visualization up to 8 mm below the skin to confirm treatment depth and avoid bone (FDA 510(k) K243035).

How Ultherapy PRIME compares with other lifting approaches

Ultherapy PRIME is not the same as radiofrequency tightening, and it is not a substitute for surgery when sagging is severe. The comparison below summarizes how the clinic frames the main alternatives.

Approach	Main layer targeted	Incisions	Typical downtime	Best suited to
Ultherapy PRIME (micro-focused ultrasound)	Deep dermis and SMAS, at chosen depths	None	Zero to minimal	Mild to moderate laxity, jawline and lower-face lift
Radiofrequency tightening (for example, Thermage)	Dermis, heated in bulk	None	Minimal	Overall dermal firmness rather than SMAS contraction
Surgical facelift	Skin, SMAS, and deeper tissue repositioned	Yes	Significant	Severe sagging that needs excess skin removed

The practical difference is depth control. RF devices warm a broad volume of dermis, whereas focused ultrasound concentrates energy at defined points and can reach the layer a surgeon would tighten. A facelift still produces longer-lasting structural change, but it brings incision risks, a longer recovery, and higher cost, which is why many visitors with early laxity start with a non-surgical option.

Who Performs Ultherapy PRIME at Doctorpetit Clinic Hongdae

Dr. Chae-ho Lee
Medical Director at Doctorpetit Clinic Hongdae

Dr. Chae-ho Lee, the Medical Director, performs every Ultherapy PRIME treatment at the clinic, and he is its only physician. Ultherapy PRIME is one of the subspecialty techniques listed in his profile, and it is named in his clinic biography alongside ONDA as a focus of his non-surgical lifting work. Before joining Doctorpetit Clinic Hongdae he served as a director at Lienjang Clinic Hongdae and at Doctorpetit Clinic Gangnam. He belongs to the Korean Society of Aesthetic Plastic Laser Medicine and the Korean Society of Laser Dermatology & Hair. Because the same doctor reads the ultrasound image, chooses the transducer depths, and delivers the energy, the plan you agree at consultation is the plan that is carried out.

Who Is a Good Candidate for Ultherapy PRIME?

Suitability is decided in person, after direct skin analysis and an ultrasound look at your tissue depths.

You may be a good candidate if you have:

• Mild to moderate skin laxity on the face or neck.
• Early jowling or sagging along the lower face.
• A jawline that has lost some of its definition.
• Fine lines around the eyes or other early signs of ageing.
• Early facial volume loss and a preference for subtle, natural-looking lifting.
• A short trip to Seoul and a need for a treatment with little or no downtime.

Ultherapy PRIME may not be suitable, or may need to wait, if you have:

• Severe sagging that would need open surgery to remove excess skin.
• An active skin infection or open wounds in the area to be treated.
• Metallic implants in the treatment zone.
• A current pregnancy.

If volume loss rather than laxity is the main reason a contour looks softer, the doctor may suggest an injectable approach instead of, or as well as, ultrasound lifting.

Why visitors from the U.S. ask for it

Patients from the United States most often request Ultherapy PRIME because it can deliver meaningful tightening and contour definition without cuts, scars, or a recovery period that would eat into a trip. The goals they describe tend to be specific: a crisper jawline, lifted cheeks and lower face, firmer skin, and a smoother texture, while still looking like themselves. Realistic expectations matter here. The result is a natural-looking lift, not the repositioning a surgeon can achieve, and it develops over weeks rather than overnight.

What to Expect: Procedure, Recovery, and Results Timeline

Preparing for your visit

In the days before treatment, avoid chemical peels, strong retinoids, and other harsh skin irritants. Limit intense sun exposure. Tell the team about any recent injections, cosmetic procedures, or medical conditions. Blood-thinning supplements and alcohol are best avoided just before the appointment, but do not stop a prescribed medicine without first discussing it with the doctor.

The treatment, step by step

1. Consultation and mapping. Dr. Lee examines your skin and lifting goals, then uses real-time ultrasound imaging to map target depths and build a personalized plan.
2. Preparation. The skin is cleansed and the treatment areas are marked.
3. Numbing. Topical numbing cream is applied before energy delivery; no sedation or IV anesthesia is used.
4. Ultrasound treatment. Focused ultrasound is delivered to each planned area, with the doctor watching the tissue image on screen.
5. Finishing. The skin is checked and gently soothed.
6. Aftercare briefing. You receive short written instructions before you leave.

The whole session usually takes 30 to 60 minutes, depending on the areas treated and the planned shot count.

How it feels

Most patients describe a tolerable, deep warming sensation at the moments energy is delivered. The clinic reports that discomfort is reduced compared with older ultrasound devices, helped by numbing cream and by the faster energy delivery of the PRIME system. In published research on MFU with visualization, patients rated pain as moderate on average, which is worth knowing before you book.

Recovery and results timeline

When	What usually happens
Immediately after	You can return to daily activities and travel plans; makeup can usually be applied straight away. A subtle tight feeling is common.
First few days	Mild redness, minor swelling, slight bruising, tenderness, or tingling may appear and typically fade within several days.
First 24–48 hours	Use daily sunscreen and keep skin hydrated. Avoid hot saunas, steam rooms, and strenuous exercise.
4–8 weeks	Firming and lift become easier to see as structural contraction develops.
2–3 months	Main collagen remodeling is reached and the final result can be judged.
12 months or longer	Results typically last up to a year or more, depending on individual skin condition.

For U.S. visitors, a stay of about 1 to 3 days covers consultation, treatment, and a check-up. Many people can fly home the same day or within 24 to 48 hours, because focused ultrasound carries no cabin-pressure restrictions.

Looking after your skin at home

Keep the treated skin well moisturized and wear broad-spectrum sunscreen every day. For the first one to two days, skip saunas, steam rooms, hot baths, and hard workouts, since extra heat can prolong redness. Normal cleansing and makeup are fine. Mild tingling or tenderness in the treated area can last a few days and usually settles on its own. If anything looks unusual after you are home in the U.S., contact the clinic by its website or by phone, and see a local doctor promptly for severe or worsening symptoms.

Combining Ultherapy PRIME with Other Treatments

Ultrasound lifting tightens the structure but does not add volume or improve surface hydration on its own. After assessment, the clinic often pairs it with:

• Skin Boosters & Biostimulators — to support hydration and skin quality alongside deeper tightening.
• Dermal Fillers — when lost volume, rather than laxity alone, is flattening the cheek or jawline.
• Botox Treatments — neuromodulator injections for expression lines that lifting does not address.

Whether to combine, and in what order, is decided at the consultation according to your face and your travel schedule.

Safety, Precision, and Clinic Standards

The Korean Ministry of Health and Welfare has listed Doctorpetit Clinic Hongdae as a registered medical institution for attracting foreign patients since January 2023. Every Ultherapy PRIME plan begins with a 1:1 evaluation by the Medical Director. The clinic reduces risk by using real-time ultrasound imaging to monitor tissue depth throughout treatment. The clinic states that it uses authentic equipment and genuine products. English consultation and interpretation are available during your visit.

Known risks and side effects

Common effects are temporary redness, minor swelling, slight bruising, and mild tenderness in the treated area. These usually disappear within several days. Tingling or temporary nerve sensitivity can also occur. A rare risk is temporary superficial skin dimpling, which can occur if energy depth is not mapped properly. That is one reason depth visualization matters.

The wider evidence on this technology is reassuring but not risk-free. A systematic review and meta-analysis of 42 studies found that 89% of patients showed some degree of global aesthetic improvement as rated by investigators. It also reported that common adverse events, such as erythema, swelling, bruising, and tenderness, were generally mild to moderate (Aesthetic Surgery Journal meta-analysis of MFU-V). The same analysis recorded a pooled pain score of 4.85 out of 10.

The Bottom Line

• Ultherapy PRIME uses micro-focused ultrasound at 1.5, 3.0, and 4.5 mm to lift and firm mild to moderate laxity, including at the SMAS level.
• DeepSEE real-time imaging lets Dr. Chae-ho Lee see tissue layers while treating, which supports accurate depth placement.
• A session takes 30 to 60 minutes with numbing cream, and most people return to normal plans the same day.
• Lift builds over 2 to 3 months and typically lasts up to 12 months or longer.
• Severe sagging is better suited to surgery, and that judgment is part of the consultation.

Frequently Asked Questions

How is Ultherapy PRIME different from the original Ultherapy?
PRIME is the newer platform of the same Ulthera System. Its DeepSEE imaging gives the doctor a real-time view of the tissue, and energy is delivered faster, which the clinic says lowers overall discomfort. The underlying micro-focused ultrasound principle is unchanged.

How does Ultherapy PRIME compare with Shurink or other HIFU devices?
Both use focused ultrasound to heat deep layers. The main difference is that Ultherapy PRIME builds visualization into the treatment, so tissue depth is checked on screen as each line is placed. Dr. Lee can explain which device suits your laxity after examining you.

What does "Ultherapy shots" mean?
Each pulse of focused ultrasound is called a shot or line. The number planned depends on the areas treated, and it is one of the factors that sets the session length of 30 to 60 minutes.

Do I need anesthesia?
No general anesthesia or IV sedation is used. Topical numbing cream is applied to the skin before energy delivery, and most patients describe the sensation as a deep warmth that is tolerable.

When will I see the lift, and how long will it last?
A subtle tightness can be felt right away, and clearer contraction usually appears within 4 to 8 weeks. Final results are judged at around 2 to 3 months and typically persist for 12 months or longer.

Can I fly back to the U.S. straight after treatment?
Usually, yes. There is no recovery period that keeps you grounded, so many patients fly the same day or within 24 to 48 hours. Plan about 1 to 3 days in Seoul so consultation, treatment, and a follow-up check fit comfortably.

Is Ultherapy PRIME safe for international patients?
Side effects are usually mild and short-lived, such as redness, swelling, or tenderness. The clinic has been registered to treat foreign patients since 2023, and Dr. Lee confirms your individual suitability at the consultation before any energy is delivered.

Will my doctor speak English?
English consultation interpretation is available, so you can describe your goals and ask questions in English. Dr. Lee meets every patient personally before treatment.
