Focused Ultrasound Depths at a Myeongdong Skin Clinic

Focused ultrasound devices such as Ultherapy (Ultherapy Prime) and Shurink Universe, sold abroad as Ultraformer MPT, swap handpieces or cartridges to place heat at fixed depths below the surface. The depth decides which layer is treated, so it matters more than the device brand when you read a plan.

A typical plan mixes two or three depths on one face, and Shurink adds a 2.0 mm cartridge between the shallow and middle settings. The doctor adjusts depth to your skin thickness and the area.

Laubach and colleagues tested an early focused ultrasound prototype on donated postmortem human skin, reported in Dermatologic Surgery in 2008. The device ran at 7.5 MHz with a nominal focal distance of 4.2 mm, and each pulse lasted between 50 and 200 milliseconds.

Under the microscope, each pulse left a small, separate zone of heat damage below the epidermis, shaped like an upside-down cone and reaching as deep as 4 mm within the dermis. Power, pulse time and focal depth together set how deep and how large each zone was, and moving the probe step by step built a regular grid of points.

This was laboratory tissue, not living patients, so it says nothing about how much lift a person sees. It does explain why a written depth on your plan means something: the heat lands where the settings put it.

Plan the session for the afternoon of a lighter day, allowing time for numbing cream before the 30 to 60 minutes of treatment. Someone who typed skin clinic seoul myeongdong into a map app usually wants a walkable slot near the hotel, which is realistic because most people need no recovery room.

Redness tends to settle within hours. Tenderness along the jaw, mild swelling or tingling can last several days, and chewing firm food may feel sore. Makeup is commonly allowed the next day. Results build gradually as collagen remodels, so the change is usually judged weeks to a few months later, well after a short trip ends.

• Skip the sauna, hot bath and hard exercise for the first day or two, as many clinics advise.
• Use sunscreen and a hat on the street; treated skin can stay slightly sensitive.

Ask to see the device and the cartridge or transducer in use, which depths are planned for each area, and who will perform the treatment. A clear plan states the depth and the line or shot count per area, so a later session can be compared with this one.

Postpone focused ultrasound during pregnancy, and over broken skin, an active breakout or a healing wound in the area. Tell the doctor about any metal implant, thread lift or recent filler in the face. Very thin faces with little fat may look more hollow if deep settings are overused. Marked sagging or loose neck skin may respond better to another treatment or a surgical consultation; a lift from energy alone is modest and varies from person to person.
