HIFU (high-intensity focused ultrasound) delivers focused ultrasound energy to deeper layers beneath the skin, including the SMAS layer, to help tighten and lift without needles or incisions. In Korea it is most often offered with devices such as Ulthera and Shrink, and clinics usually price it by the number of shots and the treated area — full face, jawline, under the chin, or neck. On Seolle you can compare starting prices by clinic, reserve a consultation before you travel, and communicate in your preferred language.
It depends on the clinic, the device, the number of shots, and the area treated. Compare current starting prices by clinic on Seolle.
Both are focused-ultrasound devices: Ulthera lets the practitioner view the skin layers on an ultrasound image during treatment, while Shrink is a Korean-developed HIFU device. Which device, depth, and shot count fits you is decided by the doctor based on your skin and goals.
Many people feel pulses of deep heat or prickling, especially over bony areas, and some clinics apply numbing cream beforehand. Mild redness, swelling, or tenderness may appear and usually fades within a few days, so most people return to daily activities soon after.
It is often done as a single session, with tightening that tends to develop gradually over the following weeks to months. How often to repeat it varies by person, so ask your doctor about a maintenance plan.
Because downtime is usually short, HIFU often fits into a trip itinerary. Book a consultation through Seolle before you travel, tell the doctor about any recent fillers or procedures, and check whether an interpreter is available.
