Thread lift vs Ulthera Prime at a glance

Both treatments aim to lift sagging tissue without surgery, but they get there differently. A thread lift places dissolvable threads under the skin to physically reposition tissue, while Ulthera Prime uses focused ultrasound to tighten the deeper support layer from within.

Feature	Thread Lift	Ulthera Prime
Technology	Dissolvable PDO (polydioxanone) threads, often barbed	Microfocused ultrasound with real-time imaging (Merz)
How it works / target depth	Threads placed in the fat layer anchor and lift tissue, then stimulate collagen as they dissolve	Focused thermal points at about 1.5, 3.0 and 4.5 mm, reaching the SMAS
Best for	Moderate jowls, deeper smile lines and marionette lines needing a visible lift	Mild to moderate descent at the jaw, brow and under-chin
Comfort	Local anesthetic; pressure and tugging during placement	Deep heat over bone; numbing cream used
Downtime	3–7 days of swelling or bruising	None to mild swelling or tenderness
Sessions	One; repeated when the effect fades	Usually one per year
Results appear	Immediately, refining as swelling settles	Gradual; peak at 2–3 months
Results last	About 12–18 months	About 12 months or longer
Price from at Dernia	₩690,000 (per area; thread count varies)	₩390,000 (100 lines)

How a thread lift works

After local anesthetic, your doctor inserts fine cannulas through tiny entry points and lays PDO threads along planned vectors in the fat layer. Barbed threads grip the tissue so it can be lifted and repositioned, giving a visible change on the day. Over roughly six months the threads dissolve, and the collagen that forms around them helps support the result for longer. Expect swelling, some bruising and a tight feeling when you open your mouth wide for the first days. Rare risks include dimpling, asymmetry and a thread end that needs adjusting.

How Ulthera Prime works

Ulthera Prime focuses ultrasound into tiny thermal points at set depths, including the 4.5 mm level of the SMAS, the supportive layer a surgeon tightens in a facelift. Real-time imaging lets your doctor see each tissue layer and place energy precisely. There are no needles or entry points, and the surface stays intact. The lift builds over two to three months as the treated tissue contracts and remodels. Ultherapy is FDA-cleared to lift the brow and the skin of the neck and under the chin.

Choose a thread lift if…

You want an immediate, visible lift of jowls or smile lines
Your sagging is moderate and energy devices alone may not be enough
You can plan for three to seven days of swelling and bruising
You want to reposition tissue, not just tighten it

Choose Ulthera Prime if…

You prefer a non-invasive treatment with no needles
Your descent is mild to moderate
You need to be presentable straight away, with no visible recovery
You are happy for results to build gradually

Can you combine them?

Yes. Many doctors see them as complementary: Ulthera tightens the deep layer while threads reposition tissue more strongly. A common approach is Ulthera first, with threads placed the same day or a few weeks later. If threads come first, doctors usually wait several weeks before using ultrasound over them. Your doctor will set the sequence based on your anatomy and travel dates. Filler can also be added where sagging has left hollows.

Cost comparison

At Dernia Clinic Myeongdong, thread lifts start from ₩690,000 per area, with the final price depending on the type and number of threads. Ulthera Prime starts from ₩390,000 for 100 lines, and a full face and jawline needs several hundred lines. Compare plans on the thread lift price page and the Ulthera Prime price page. Prices are in Korean won (KRW), exclude 10% VAT, and are confirmed at your consultation.

How our doctors decide

Your doctor assesses how far tissue has descended, your skin thickness, facial fat and your schedule. Moderate jowls or marionette lines with a desire for visible change point to threads; mild descent or no tolerance for downtime points to Ulthera. If you are unsure how much lift you need, Ulthera is the lower-commitment place to start, and threads can be added later. For threads, schedule early in your stay so your doctor can check you before you fly.

Threads are not placed during pregnancy, over active infection, or without careful review if you take blood thinners or have a bleeding disorder.

Does a thread lift give better results than Ulthera?

A thread lift gives a more immediate and often more visible lift for moderate sagging. Ulthera gives a subtler, gradual result with no downtime. Which is better depends on how much lift you need and how much recovery you can accept.

How long is recovery after a thread lift?

Most people have swelling or bruising for three to seven days and a tight feeling when opening the mouth wide. Avoid facial massage, dental work and strenuous exercise for the period your doctor advises.

Can I fly after a thread lift?

Many people fly within a few days, but it is wise to have a follow-up check before you leave Seoul. Plan your thread lift early in your trip.

Do the threads stay in my face?

No. PDO threads dissolve over roughly six months. The collagen that forms around them helps support the result for longer.

Can I have Ulthera after a thread lift?

Yes, but doctors usually wait several weeks after threads before using ultrasound over the area. Your doctor will advise on timing for your plan.
