Quick answer: Ultherapy alone lifts the deep SMAS layer with focused ultrasound and suits mild to moderate sagging. Ultherapy and Thermage combined adds radiofrequency to tighten the skin surface as well, so the face looks lifted and smoother. Choose Ultherapy alone for sagging with good skin quality, and the combination for sagging plus loose, crepey skin.
Key takeaways
- Ultherapy works deep, at the SMAS and deep dermis.
- Thermage works on the dermis, tightening the skin itself.
- Together they treat the face in layers, from deep to surface.
- The combination often suits people in their 40s and older.
- Both can be done on the same day with little downtime.
What does Ultherapy do on its own?
Ultherapy is a micro-focused ultrasound treatment by Merz Aesthetics. The doctor uses live imaging to place small heat points at 1.5 mm, 3.0 mm and 4.5 mm. The deepest points reach the SMAS, the layer that a surgeon lifts in a facelift. Over two to three months, new collagen forms and the jawline, cheeks and brows look gently lifted. Results usually last about a year.
What does Thermage add?
Thermage FLX uses monopolar radiofrequency to heat the dermis evenly over a wide area. The heat tightens collagen fibres right away and builds new collagen over the next few months. While Ultherapy lifts from below, Thermage improves the skin itself: fine lines, crepey texture, loose skin around the eyes and a dull surface. That is why the two are often described as a layered treatment.
How do the two plans compare?
- Layers treated: Ultherapy alone treats the deep layer; the combination treats deep and surface layers.
- Main result: alone gives lift; combined gives lift plus tighter, smoother skin.
- Best for: alone suits early sagging with firm skin; combined suits sagging with loose or thin skin.
- Treatment time: alone about 30 to 90 minutes; combined about 90 to 150 minutes.
- Downtime: both usually only mild redness, swelling or tenderness.
Who is Ultherapy alone best for?
Ultherapy alone often suits people in their 30s and early 40s whose skin is still firm but whose jawline is starting to soften. It also suits people who mainly want a lifted brow or a clearer line under the chin. If your skin texture is good and your main concern is drooping, one lifting treatment may be enough.
Who benefits from the combination?
The combination often suits people who notice two problems at once: sagging jowls and skin that looks loose, thin or crepey. It is common for people in their 40s, 50s and older, and for those who want the most complete non-surgical result from one visit. Visitors with limited time in Korea also like doing both in one session.
Same day or separate days?
Both can be done on the same day, which is convenient for visitors. Many doctors perform Ultherapy first for the deep layer and then Thermage for the surface. Some prefer to separate them by a few weeks for comfort. Your doctor will plan the order after checking your skin and your travel dates.
What is the downtime?
Downtime is low for both. You may have redness and warmth for a few hours, and mild swelling or tenderness along the jaw for a few days. Small bruises are possible but uncommon. Most visitors can go sightseeing the same day and fly home the next day.
Is it safe to combine?
Yes, when planned and performed by an experienced doctor using genuine devices and tips. The energy level is adjusted so the skin is not overheated. Rare risks include small burns, blisters or temporary numbness. Tell your doctor about recent fillers, threads, metal implants or pacemakers.
How to decide
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Lifting combinations are among the most popular plans. The key question is whether your concern is sagging only, or sagging plus skin quality. A face assessment helps your doctor decide whether one device is enough.
Frequently asked questions
Is the combination much stronger than Ultherapy alone?
It treats more layers, so many people see both lifting and smoother skin, but results vary.
Which is done first?
Often Ultherapy first, then Thermage, but your doctor decides the order.
How long do results last?
Both usually last about a year, and results build over two to six months.
Can I add skin boosters too?
Yes. Many people add Rejuran or other boosters later for skin quality.
