Ulthera or Thermage: Which One Fits You?

TL;DR: The choice between lifting devices comes down to three things: whether the sagging starts at the SMAS and deep tissue or at a loss of dermal density, how many recovery days you can spend in Seoul, and your pain tolerance plus recent treatment history. Focused ultrasound devices concentrate heat at a single depth, while radiofrequency devices warm a broader volume, so they reach different layers and recover differently. At our Seocho consultations, we check these three points before we ever say a device name out loud.

We hear the same question almost every day at our Seocho clinic: “Should I get Ulthera or Thermage?” The short answer is that the two are not interchangeable options competing for the same job. They are built to heat different depths of tissue. That is why we start a consultation with photos, an assessment of facial movement, skin thickness, and recent procedure history, and only bring up a device name once we know which layer needs the work.

Focused Ultrasound and Radiofrequency Heat Tissue Differently

Focused ultrasound devices concentrate energy at a single point. A 2023 systematic review by Contini and colleagues in the International Journal of Environmental Research and Public Health describes microfocused ultrasound (MFU) as creating tiny thermal coagulation zones of roughly one cubic millimeter at a set depth while leaving the surrounding tissue untouched. The same review identifies the deep dermis and the SMAS (superficial musculoaponeurotic system), a layer of subcutaneous connective tissue, as the intended targets. An Asian expert consensus review published in the Journal of Clinical and Aesthetic Dermatology describes ultrasound-guided MFU-V devices delivering energy at three depths: 1.5mm, 3.0mm, and 4.5mm.

Radiofrequency devices work the opposite way, warming a wide volume instead of a single point. A review of radiofrequency for facial rejuvenation in the International Journal of Dermatology and Venereology reports that monopolar radiofrequency protects the epidermis through cooling while raising the dermis to roughly 65 to 75 degrees Celsius, with penetration depth around 20 to 25mm, deeper than bipolar systems. Bipolar devices keep current flowing between two electrodes close together, which limits the effect to a comparatively shallow layer.

Sofwave uses ultrasound too, but it does not focus the energy at a point. A 2025 study by Boonchoo and Hongcharu in the Journal of Cosmetic Dermatology describes multiple synchronized transducers sending parallel beams that create a cylindrical thermal zone in the mid-dermis, at a depth of roughly 0.5 to 2mm, heated to 60 to 70 degrees Celsius. A histology study in the same journal found increased collagen and elastic fibers in the mid-dermis after treatment. Because the target stays in the dermis, Sofwave sits in the ultrasound family by mechanism but behaves more like a radiofrequency device in terms of the layer it reaches.

Category	Focused ultrasound	Non-focused parallel-beam ultrasound	Radiofrequency	Microwave
How heat is made	Ultrasound concentrated at a point, forming micro thermal coagulation zones	Parallel beams spread wide, forming a cylindrical thermal zone	Current meets tissue resistance and converts to heat; epidermis is cooled	2.45GHz waves agitate water and fat molecules through dielectric heating
Primary target layer	Deep dermis to SMAS (1.5, 3.0, 4.5mm)	Mid-dermis (0.5 to 2mm)	Monopolar reaches below the deep dermis; bipolar stays in the shallow dermis	Subcutaneous fat layer; a shallower handpiece reaches the dermis
Typical recovery pattern	Redness and swelling are common, usually resolving within 5 to 7 days per the MFU-V consensus	Manufacturer materials describe a short recovery window	Cooling limits epidermal damage, though warmth and redness can occur	Cooling is built in; temporary redness has been reported
Pain tendency	Reported in the literature as moderate	Warmth during four to five second pulses	Varies widely with energy level and how closely the tip contacts skin	Paired with contact cooling
Our Seocho lineup	Ulthera, Shurink	Sofwave	Thermage, Oligio X, InMode	Onda

The recovery and pain rows above describe patterns reported in the literature; individual response depends on the treated area, energy settings, and skin condition.

Onda Is Built for the Fat Layer

Onda works on a different principle from either family above. The Onda Coolwaves International Advisory Board, in 2024 recommendations published in Bioengineering, describes the device using 2.45GHz microwave energy that is selectively absorbed by subcutaneous fat through a physical process called dielectric heating. The same recommendations note that Onda uses separate deep and shallow handpieces, both built with cooling to protect the epidermis. When a patient’s concern involves fat under the chin or along the jawline alongside sagging, we place Onda next to the sagging-focused devices and talk through which one to address first.

The Concern Comes First, Not the Device Name

The same phrase, “I have no elasticity left,” points to different causes depending on the patient. The table below lists what we check first in consultation and which device family becomes a candidate as a result.

Concern	What we check first	Candidate family
Jawline or cheek sagging	Difference between a resting expression and a smile, subcutaneous fat distribution, direction of sagging	Focused ultrasound reaching the deep layers, monopolar radiofrequency
Fine lines, texture, pores	Change after hydration, whether wrinkles appear only with expression, retinoid or exfoliation history	Parallel-beam ultrasound targeting the mid-dermis, shallow radiofrequency
Double chin or contour	Whether fat or sagging carries more weight, weight change history	Microwave targeting the fat layer, deep-reaching ultrasound
Under-eye area	Skin thickness, prior treatment near the eyes, botulinum toxin cycle	Radiofrequency with a small tip, shallow-depth ultrasound

Areas like the under-eye region, where skin is thin and nerves run close to the surface, are treated cautiously even in the literature. A 2026 multidisciplinary consensus on managing MFU-V complications by Dicker and colleagues in the Journal of Cosmetic Dermatology emphasizes staying clear of “no-go zones” near nerves and confirming placement with real-time ultrasound imaging as prevention strategies. That is why we confirm the treatment boundary for this area before anything else in consultation.

If You Are Fitting This Into a Travel Schedule

The question we hear most often is whether a flight the next day is realistic.

Focused ultrasound is expected to bring some redness and swelling. The 2026 consensus mentioned above describes mild to moderate erythema and edema usually settling within 5 to 7 days, occurring more frequently in patients with sensitive skin, thin or atrophic skin, or rosacea. Flying afterward is common for our patients, and if you have photos scheduled or an important commitment right after landing, mention it during consultation.

A 2025 hemifacial comparative study by Wang and colleagues in the Journal of Cosmetic Dermatology, which combined ultrasound and radiofrequency microneedling on the same day in 26 patients, reported that redness generally settled within a few hours and swelling within 3 to 72 hours without special intervention. The same study also observed purpura in some cases. Stacking multiple procedures into a short stay increases the chance that recovery responses overlap, so the tighter the schedule, the more we recommend narrowing the treatment area rather than expanding it.

Our Seocho clinic sees patients on Saturdays and Sundays from 10:00 to 18:00, with reception closing at 16:30. That means a weekday treatment can be followed by a weekend check before departure. We keep a separate guide on when to come back for a follow-up visit, and the same planning logic applies to combining a procedure with the rest of a Seoul trip, something we cover in our guide to booking a Seoul skin clinic visit from abroad.

Combining Two Families: How We Sequence It

Since ultrasound and radiofrequency act on different layers, combining them is a natural option, and the evidence for it is building. The hemifacial study by Wang and colleagues found that combining ultrasound and radiofrequency microneedling on the same day produced better outcome scores at the three-month mark than treating with a single modality, with adverse events described as mild. A 2025 Korean retrospective safety study reviewing 1,040 records across two clinics over 18 years also reported a low rate of adverse events when ultrasound or monopolar radiofrequency was combined with injectable treatments.

Combining devices comes with a tradeoff. The 2026 consensus notes that swelling can increase when ultrasound is paired with injectables or another device on the same visit. No formula for a standard order or interval has appeared in the literature yet, so rather than treating the entire face in one sitting, we typically recommend addressing the highest-priority layer first and leaving the remaining concern for a later visit. If you have had any procedure within the past year, the timing of that procedure becomes the single most important piece of information for sequencing what comes next.

Where Our Published Prices Live

Pricing depends on shot count and how the area is divided, so comparing totals alone can be misleading. Our Seocho branch publishes itemized pricing on our site. Using 300 shots as a reference point, the relevant lines read as follows (as of August 2026, subject to change):

Item	Published price
Ulthera, 300 shots	KRW 1,090,000
Thermage, 300 shots	KRW 1,390,000
Sofwave, 300 shots	KRW 2,490,000
Oligio X, 300 shots	KRW 590,000
Shurink, 300 shots	KRW 240,000
Onda, 80KJ	KRW 800,000
InMode FX, 1 area	KRW 89,000

Even at the same shot count, density per area changes depending on whether shots are spread across the full face or concentrated along the jawline. Asking “how are the shots distributed across each area” in consultation gives a much clearer picture than asking only “how many shots.” Our full itemized list is available on our Seocho branch site, and we have written separately about the three factors that decide lifting pricing.

What to Bring to Your Consultation

We ask patients to think through the following before their visit:

• The name, area, and timing of any procedure received within the past year
• History with filler or thread lifting, including product name and injection site if remembered
• The date of your last botulinum toxin treatment
• Any medications you take and whether you bruise easily
• Your travel dates in Korea and any important commitments right after returning home
• Your own tolerance for pain
• Front and side photos taken with a resting expression and with a smile

Dr. Kim Kyung-su, our Seocho branch director, handles both the consultation and the treatment in the same visit, so the plan agreed on in consultation does not need to be re-explained to a different practitioner. The devices, injectables, and materials we use are authentic products, and we open them in front of the patient before treatment. For readers weighing a solo-practice consultation against a larger chain, we cover the practical differences in our comparison of chain clinics and solo practice.

FAQ

Can I get Ulthera and Thermage on the same day?

Combining the two is used clinically because they act on different layers, and both the hemifacial comparative study and the Korean retrospective analysis mentioned above reported mild adverse events with combined treatment. As the 2026 consensus notes, however, swelling can increase when devices are combined, so if your stay is short, plan a same-day combination carefully. Whether it is appropriate depends on skin thickness and recent treatment history, which we confirm in consultation.

Should I get lifting or a peeling treatment first?

The two address different problems. Sagging is a deep dermal and sub-dermal issue, while dullness and texture are usually issues of the epidermis and upper dermis. Which one matters more to you right now, and how many recovery days you have, determines the order. We review photos and your schedule together before deciding.

Can I fly the day after treatment?

Redness and swelling from ultrasound devices are generally reported to settle within 5 to 7 days, and combined-treatment studies report swelling resolving within 3 to 72 hours. Most patients travel as planned, though individual response varies considerably. If you notice anything unusual, we recommend having it checked by a physician locally.

I am getting my first lifting treatment in my 40s. What should I look at first?

Diagnosis comes before any device list. Reduced dermal elasticity, loosening of deep support structures, and volume loss are separate problems that can appear together in one person, so the first step is identifying which one carries the most weight. We compare resting and smiling photos and check skin thickness before narrowing the candidates.

Can I book without a Korean phone number?

Yes. You can book through our KakaoTalk, LINE, or WeChat consultation channels. Reaching out two to three days before your visit makes it easier to secure your preferred time slot, and same-day requests through the same channels are also possible depending on availability.
