If you are worried about facial laxity and a blurring jawline, yet afraid that non‑surgical lifting won’t work or will be too painful, Ultherapy might put your mind at ease. It uses High‑Intensity Focused Ultrasound to precisely target the deep SMAS layer without harming the epidermis, yet stimulates natural collagen neogenesis. In Gangnam, Seoul, from localised eye treatments to full face and neck, the cost and line‑based plans are flexible, with virtually no downtime and results gradually appearing over 2‑3 months. As for which plan suits you, how much it costs, and how long it lasts – all these answers are laid out clearly, so you can decide with confidence.
Ultherapy / Ultherapy Prime uses High‑Intensity Focused Ultrasound (HIFU) technology to precisely focus energy on deep skin layers. Its core mechanism is Microfocused Ultrasound (MFU). With DeepSEE™ real‑time ultrasound imaging, the physician can “see” the structure of each skin layer during the procedure and precisely deliver energy to the SMAS layer – the deep tissue targeted in surgical facelifts. Subcutaneous temperatures reach 60℃‑70℃, forming Thermal Coagulation Points (TCPs). This thermal stimulation does not damage the epidermis but causes immediate contraction and initiates long‑term remodelling of collagen and elastin. In short, the core of Ultherapy is: Precise focusing → Deep heating → Collagen neogenesis → Natural lifting.
Suitable candidates: Those with mild to moderate laxity on the face, neck, jawline, brow area, or décolletage; those with deepening nasolabial folds, loss of jawline definition, or submental fullness due to collagen depletion; those with decreased skin elasticity after pregnancy or weight changes; and those who desire a non‑surgical lifting effect without the long downtime of a facelift. Optimal results are typically seen in those aged 30‑60.
Absolute contraindications: Active skin infection or open wounds in the treatment area; pregnancy or breastfeeding; metallic or silicone implants in the face (require physician evaluation); severe keloid tendency; recent (within 1 month) chemical peel or sunburn.
The current mainstream Ultherapy in Korea has been upgraded to the second‑generation Ultherapy Prime, offering clearer real‑time imaging, about 20% faster treatment, and lower pain compared to the first generation. Three dedicated transducers of different depths are used – 1.5mm (dermis), 3.0mm (subcutaneous fat), and 4.5mm (SMAS) – for layered lifting tailored to different areas and skin thicknesses. Below is a comparison of mainstream Ultherapy Prime plans in Gangnam and Hongdae, Seoul, for 2026:
| Treatment Area | Recommended Lines | Transducer Depths | Suitable Candidates | Reference Price (KRW) |
|---|---|---|---|---|
| Eye / Local | 100 lines | 1.5mm | Periorbital fine lines, brow lifting | ₩350,000 – 400,000 |
| Jawline / Submental | 200‑300 lines | 3.0mm + 4.5mm | Loss of jawline definition, double chin | ₩800,000 – 1,400,000 |
| Full Face | 300‑400 lines | 1.5mm + 3.0mm + 4.5mm | Overall facial laxity, nasolabial folds | ₩990,000 – 2,000,000 |
| Full Face + Neck | 600 lines | All three depths | Combined face + neck laxity | ₩2,090,000 – 2,700,000 |
| Body | 900 lines | 4.5mm | Laxity on abdomen, arms, etc. | ₩3,190,000 – 3,330,000 |
Selection advice: For first‑timers or those on a budget, the 300‑400 line full‑face package offers the best value. If you have moderate‑to‑severe laxity or want maximum results, the 600‑line full‑face + neck option is recommended. Combination therapy (e.g., Ultherapy + Thermage FLX) achieves a dual “lifting + tightening” effect, with package prices starting around ₩2,990,000.
Step 1 – Consultation: The Korean dermatologist uses DeepSEE™ real‑time ultrasound imaging to assess skin thickness, SMAS position, and laxity, customising a treatment plan.
Step 2 – Preparation: Cleanse the treatment area and apply topical anaesthetic cream for about 30‑45 minutes to enhance comfort.
Step 3 – Precision procedure: After applying ultrasound gel, the physician delivers energy sequentially using 1.5mm, 3.0mm, and 4.5mm transducers under real‑time imaging. Treatment takes about 20‑60 minutes depending on the area. Sensation is deep warmth and mild tingling, well within most people’s pain tolerance.
Step 4 – Post‑care: You can wash your face and apply makeup immediately. Post‑care instructions include: use lukewarm water for 3 days, and avoid sauna, alcohol, and exfoliation for 1 week.
Immediate effect: A mild tightening sensation may be felt right after treatment; some experience mild redness or swelling, which usually subsides within hours to 1‑2 days.
Progressive effect: Ultherapy’s results are progressive – collagen neogenesis takes time. Noticeable lifting begins at 1‑2 months, peaks at 2‑3 months, and continues to improve for up to 6 months.
Duration: A single session typically lasts 12‑24 months, depending on individual age, collagen metabolism, and lifestyle. Maintenance every 6‑12 months is recommended.
Q1: Is Ultherapy painful?
A: With topical anaesthetic, most experience deep warmth and mild tingling. The second‑generation Ultherapy Prime has more refined energy delivery, significantly reducing pain compared to the first generation. Most find it well‑tolerated.
Q2: How soon will I see results? How long do they last?
A: Results are progressive – noticeable at 1‑2 months, peaking at 2‑3 months. A single session lasts 12‑24 months; maintenance every 6‑12 months is advised.
Q3: What is the difference between Ultherapy and Thermage?
A: The core differences are depth of action and primary function. Ultherapy uses HIFU on the SMAS layer (4.5mm) for lifting; Thermage uses RF on the dermis for tightening. They are often used in combination for a dual lifting + tightening effect.
Q4: How much does Ultherapy cost in Korea?
A: In 2026 Gangnam/Hongdae, Ultherapy Prime prices vary by lines and area: Eye 100 lines ~₩350,000‑400,000; Full Face 300‑400 lines ~₩990,000‑2,000,000; Full Face + Neck 600 lines ~₩2,090,000‑2,700,000; Body 900 lines ~₩3,190,000‑3,330,000. Packages and combination therapies are usually more cost‑effective.
Q5: Which dermatology clinics in Korea are good for Ultherapy?
A: Seoul Gangnam and Cheongdam‑dong have many certified dermatologists. Choose clinics that use official Ultherapy Prime equipment with DeepSEE™ imaging, operated by certified Key Doctors. You can check clinic credentials and real‑time prices via platforms like BeautsGO.
Common side effects: Temporary erythema, mild oedema, tingling, or tenderness may occur. Very rarely, white line marks may appear and resolve within hours; rare facial indentation or fat atrophy is extremely uncommon.
Rational advice: Ultherapy is an FDA‑cleared non‑invasive lifting device with significant effects, but it is not a “one‑time fix.” Before treatment, confirm that the clinic uses genuine Ultherapy Prime equipment and original cartridges, and that the procedure is performed by an experienced board‑certified dermatologist. Be honest about your medical history and medications. Manage expectations realistically – Ultherapy provides natural, progressive lifting but cannot replace a surgical facelift. Beauty is worth investing in, but Safety always comes first.
