LDM
LDM is a dual-frequency ultrasound treatment, two frequencies alternated rapidly, used in Seoul dermatology as a gentle, no-downtime maintenance and calming item. Locals treat it like skincare with a machine: frequent, unglamorous, often attached to other treatments rather than starring on its own.
A German-built ultrasound device that alternates rapidly between two frequencies, run over the skin with a handpiece and gel. No needles, no heat event, no numbing protocol. On Seoul menus it lives in the calming and barrier column: the gentle end of the machine list.
As the metronome of a maintenance calendar: the item with the shortest cadence on the local menu, repeated more like a facial than a device treatment, and as the standard companion booked around stronger treatments. It is what fills the local calendar between the items visitors have heard of: the texture of what locals repeat.
The cheap end of the device menu, priced per session and sold in course bundles locally. It also pads out visitor packages nicely, which is worth knowing when a bundle looks generous. Itemization tells you what the padding costs. See the local price.
None is the norm. It is the same-day-everything category. If a clinic pairs it with something stronger, the downtime is the stronger treatment's. Your clinic's word, as always, is the binding version.
This page describes what a treatment is and how locals buy it. It is not medical advice, it promises no outcome, and it names no clinic. Whether any treatment suits you is a question for a doctor who has seen your skin. Last checked: 30 July 2026.
