Quick answer: For jawline definition, Ultherapy tightens the deep SMAS layer with focused ultrasound, giving a gradual, natural lift with no needles. MINT thread lift uses barbed PDO threads to pull sagging jowls up right away. Ultherapy suits early softening of the jawline; MINT suits clearer jowls and people who want a visible change quickly.
Key takeaways
- Ultherapy is non-invasive; MINT Lift is minimally invasive.
- Ultherapy results build over two to three months; MINT gives an instant lift.
- MINT threads are PDO and dissolve over several months.
- MINT has more swelling and tightness for one to two weeks.
- Many people combine both for a sharper, longer-lasting jawline.
Why does the jawline lose definition?
With age, the SMAS support layer and the skin lose collagen and elasticity. Fat pads in the cheeks slowly move down, and the area along the jaw starts to form jowls. Weight changes and genetics also play a part. The result is a jawline that looks softer, wider or uneven from the side. The best treatment depends on how much tissue has dropped.
What is Ultherapy?
Ultherapy is a micro-focused ultrasound treatment by Merz Aesthetics. With live imaging, the doctor places small heat points at 1.5 mm, 3.0 mm and 4.5 mm. The deep points tighten the SMAS along the jaw and under the chin. New collagen forms over two to three months, so the jawline looks cleaner and slightly lifted. Results usually last about a year.
What is MINT thread lift?
MINT Lift uses PDO (polydioxanone) threads with small barbs, made by HansBiomed in Korea. After numbing, the doctor inserts the threads under the skin with a fine cannula. The barbs hold sagging tissue and lift it into a higher position, so you see a change right away. The threads dissolve over several months and encourage collagen around them.
How do Ultherapy and MINT Lift compare?
- Method: Ultherapy uses ultrasound energy; MINT uses dissolvable barbed threads.
- Needles: Ultherapy none; MINT small entry points with local anaesthetic.
- When you see results: Ultherapy gradually; MINT immediately.
- Strength of lift: Ultherapy mild to moderate; MINT moderate to strong.
- Downtime: Ultherapy a few days of mild tenderness; MINT one to two weeks of swelling or tightness.
- How long it lasts: Ultherapy about a year; MINT often about one year or more.
Which is better for early jawline softening?
If your jawline is only starting to blur and your skin is still firm, Ultherapy is usually the better first step. It tightens the support layer without needles, and you can go back to normal plans the same day. It is also a good yearly treatment to keep the jawline sharp.
Which is better for visible jowls?
If jowls are clearly visible or one side hangs lower than the other, MINT Lift often works better. The threads physically reposition the tissue, so the jawline line is redrawn right away. It is a common choice for people who want a strong change without surgery.
Can you combine them?
Yes. This is a popular plan in Korea. MINT gives the immediate lift, and Ultherapy tightens the deep layer and builds collagen to support the result. Doctors may do Ultherapy first and threads a few weeks later, or the other way round. If the jaw looks wide because of muscle or fat, jaw Botox or fat reduction may also be added.
What is the recovery like?
After Ultherapy, mild swelling or tenderness along the jaw can last a few days. After MINT Lift, expect swelling, small bruises, a tight feeling and sometimes small dimples for one to two weeks. Avoid wide mouth opening, facial massage, saunas and hard exercise for a short time. Plan a few days in Seoul before flying after threads.
Is it safe?
Both are safe in experienced hands. Ultherapy risks are rare and include small burns or temporary numbness. MINT risks include bruising, uneven contours, threads that can be felt and, rarely, infection. Choose an experienced doctor and genuine, approved threads.
How to choose
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Jawline treatments are among the most requested by visitors. Your choice depends on how much sagging you have, how quickly you want results and how much recovery time your trip allows.
Frequently asked questions
