Ultherapy vs Thread Lift: Non-Surgical Lifting Options Compared
Ultherapy and thread lifts are the two non-surgical lifting options visitors to Busan ask about most. Both can improve sagging cheeks and jowls without a facelift, but they work in completely different ways. One uses ultrasound energy and needs no needles; the other places dissolvable threads under the skin. The difference shows up in how quickly you see results, how much downtime you have and how the treatment fits around your trip.
Quick answer: Ultherapy uses imaging-guided focused ultrasound to tighten the deep SMAS layer, with no needles and no real downtime, and the lift builds gradually over 2–6 months. A thread lift, such as MINT cog threads, mechanically lifts and anchors tissue straight away, with 2–3 days of tightness and swelling and a few weeks of precautions. Choose Ultherapy for a gradual, low-downtime lift; consider threads when you want a more visible, immediate repositioning and can accept a short recovery.
How each option works
Ultherapy
Ultherapy, from Merz Aesthetics, delivers micro-focused ultrasound while the practitioner watches the skin layers on screen. Lines of energy are placed at chosen depths down to the SMAS, the layer tightened in surgical facelifts. Tiny heated points contract the tissue and trigger collagen renewal, so the face firms and lifts over the following months.
Thread lift
A thread lift uses fine, dissolvable threads placed under the skin through a needle or cannula. Cog threads such as MINT have small barbs that grip soft tissue so it can be lifted and held in a new position. Smooth mono threads have no barbs and are used in a mesh pattern for texture and firmness rather than lift. As the threads slowly dissolve, the body forms collagen around them.
Key differences
- Mechanism: heat and collagen remodelling (Ultherapy) vs physical repositioning plus collagen (threads).
- Speed of result: gradual over months vs visible on the day, refining as swelling settles.
- Needles: none for Ultherapy; threads are placed under local anaesthetic.
- Downtime: minimal for Ultherapy; 2–3 days of tightness, swelling and possible bruising for threads.
- Duration: both typically about 6–12 months.
- Precautions: a day of avoiding heat after Ultherapy; several weeks of avoiding massage, wide mouth opening and side sleeping after threads.
Who suits which
Ultherapy may suit you if
- You have mild to moderate sagging of cheeks, jowls or brows.
- You want no needles and essentially no downtime.
- You are happy for results to appear gradually and look natural.
A thread lift may suit you if
- You have more noticeable sagging of the cheeks, jowls or jawline.
- You want a visible lift without waiting months.
- You can accept a few days of swelling and some weeks of care.
When to consider something else
If the main issue is crepey skin rather than sagging, radiofrequency such as Thermage FLX is often more suitable. Very loose skin can have limits with any non-surgical approach, and a doctor should tell you honestly if that is the case. Threads and Ultherapy are both avoided during pregnancy and over active infection in the area, and you should mention any recent fillers or threads.

Prices checked October 2026. They exclude 10% VAT, and prices change often. For threads, the number and type of threads drives the cost; for Ultherapy, it is the number of lines. Ask exactly what is included before comparing.
What happens on the day
Ultherapy
- Numbing cream for about 30 minutes, then gel for the imaging probe.
- About 30–60 minutes of warm, prickly pulses, strongest near bone.
- Mild redness afterwards; you can usually go sightseeing straight away.
Thread lift
- The doctor marks the lifting vectors and entry points.
- Local anaesthetic is used, and threads are placed in about 20–30 minutes.
- The face feels tight; swelling and sometimes bruising or small dimples appear over the next 24–72 hours.
Results timeline
- Ultherapy: slight tightening at first, visible lift at 2–3 months, peak at 3–6 months, lasting about 6–12 months.
- Threads: lift visible on the day, settling over 1–2 weeks as swelling eases; collagen around the threads helps the result last about 6–12 months.
Recovery and aftercare
After Ultherapy
- Avoid saunas and jjimjilbang, hot baths, alcohol and strenuous exercise on the day.
- Expect possible jaw tenderness for a few days; rarely, temporary numbness or nerve irritation.
After a thread lift
- Choose soft foods and avoid opening your mouth very wide or chewing hard foods for 1–2 weeks.
- Skip facial massage and firm pressure for about 3–4 weeks.
- Avoid sleeping face-down or on your side for a while.
- Keep makeup off the entry points until they close, and avoid heat, alcohol and hard exercise on the day.
Planning around a trip
Ultherapy fits almost any itinerary, even a weekend. A thread lift is better done early in a longer stay, so the doctor can check you before you fly and the first days of swelling pass while you are still in Busan. Flying after threads is generally possible, but swelling can feel tighter on a long flight. Some people combine the two at different times: threads for an immediate lift, then energy treatments for maintenance.
Frequently asked questions
Which lasts longer, Ultherapy or threads?
Both typically last about 6–12 months. Longevity depends on your degree of sagging, skin quality and lifestyle more than on the method.
Can I have Ultherapy after a thread lift?
Often yes, but timing matters. Tell the doctor the date and type of threads so energy can be planned safely around them.
Are threads safe?
Dissolvable threads are widely used and generally well tolerated in experienced hands. Possible issues include bruising, dimpling, asymmetry, visible or palpable threads and, rarely, infection.
