Ultherapy (울쎄라) in Korea: What It Is, What to Ask and What to Watch For

Updated 1 November 2026

Ultherapy (울쎄라, ulsera) is one of the treatment names foreign visitors most often arrive with. The treatment is named Ultherapy, and the device is called the Ulthera System. It is a brand of device that delivers focused ultrasound energy under the skin, and it is usually offered as a non-surgical option for loose skin. This guide explains what it is, what the evidence and regulators actually say, and what to ask before you agree to it.

At a glance

Details
What it is A device that uses micro-focused ultrasound with visualization (MFU-V). The visualization feature lets the practitioner see the tissue layers on a screen.
Korean name to say 울쎄라 (ulsera)
How clinics usually quote it Often by the number of “shots” (샷, syat) and the areas treated. Ask exactly what is included.
Where it is performed In a clinic, by a doctor or under a doctor’s supervision. Ask who will hold the handpiece.
Side effects reported in studies Redness, swelling, bruising and tenderness, generally mild to moderate. Ask your doctor what to expect on your skin.

What regulators say it is for

The US Food and Drug Administration cleared the Ulthera System in 2018 (510(k) K180623) for these uses: a non-invasive dermatological aesthetic treatment to lift the eyebrow, to lift lax tissue under the chin and on the neck, and to improve lines and wrinkles of the décolleté. The same clearance covers an ultrasound visualization transducer that shows tissue layers to a depth of up to 8 mm.

Korean clinics may describe wider uses, such as lifting the lower face. That is not automatically wrong, but it is reasonable to ask what the claim is based on. An FDA clearance describes a specific list of uses for that specific device. It does not cover other machines that use a similar principle under different names.

What studies report

A systematic review and meta-analysis of 42 studies of MFU-V found that investigators rated 89% of patients as improved (n = 411) and 84% of patients reported improvement (n = 312). When a “neutral” answer was allowed, satisfaction fell to 62%, and the authors note that counting neutral answers as positive may overestimate the benefit. The average pain score was 4.85 out of 10, which the authors call moderate. Reported side effects were redness, swelling, bruising and tenderness, generally mild to moderate, and the review reports no serious adverse events.

Individual results vary, and a clinic cannot promise how much lift you will see.

Questions to ask the clinic

  1. Which device exactly will you use? Ask for the brand and model name. “Ultrasound lifting” can mean several different machines.
  2. Why do you recommend it for me? Ask what area it targets and what result is realistic for your skin.
  3. How many shots, in which areas, and at what price per area? Get it in writing on the itemised estimate.
  4. Who performs the treatment, and is a doctor present?
  5. How will pain be managed? Ask about numbing cream or oral pain relief.
  6. What are my risks, and what happens if something goes wrong? Ask who to contact after hours.
  7. Is a repeat session needed, and is it priced separately?

Frequently asked questions

Is Ulthera the same as HIFU?

Ulthera uses a type of focused ultrasound often called HIFU or MFU-V. Many machines use a similar principle under other names, and they are different products. Ask which device you will get.

Does it hurt?

Pain varies by person and area. The review above reports moderate pain on average. Ask what pain control the clinic offers.

How long do results last?

Studies and clinics report different answers, and no clinic can promise a duration. Ask the doctor what follow-up they expect.
