This is Gyeonggi Anyang Beomgye KKEUT Korean Clinic's procedure note on Skin Firming Lasers: Principles and Recommended Candidates by Type.
When you look up skin firming lasers, names like Ultherapy, Shurink, Thermage, Onda, and InMode FX all come up at once.
Though the names differ, they share one point: they are procedures that deliver energy beneath the skin to bring about changes in the tissue.
The principle and the suitable candidates differ depending on what energy is used at which layer.
Within this category, Kkeut Oriental Medicine Clinic offers Shurink, Ultherapy, radiofrequency lifting, Onda, and InMode FX.

The approach that works on deep layers with ultrasound
Shurink and Ultherapy are procedures that use high-intensity focused ultrasound (HIFU).
The principle is to gather thermal energy in the SMAS layer that supports the facial line, inducing contraction and regeneration of collagen.
Each tip has a fixed depth at which it focuses, so the 4.5mm, 3.0mm, 2.0mm, and 1.5mm specifications are used separately to suit the thickness of each area.
Ultherapy is a procedure performed while confirming the layers on an ultrasound screen.

Because the tissue goes through a process of reconstruction after the heat stimulation, changes usually appear gradually from about one month later.
This category is recommended for those whose cheeks and jawline have sagged so that the line looks collapsed.
Even people with little flesh develop sagging when the SMAS layer stretches, so it applies regardless of volume.

The approach that evenly heats the dermis with radiofrequency
Thermage, TenTherma, Oligio, Volnewmer, and Density are a family of radiofrequency (RF) lifting devices.
Monopolar RF evenly heats the dermis and subcutaneous layer, inducing denaturation and regeneration of collagen.
A checkered grid is drawn on the tip so that heat is evenly distributed, and the SuperPass technique keeps heat delivery of accumulated energy high.
This is recommended for those concerned about overall loss of firmness in the face or who also want to look at the texture and firmness of the surface layer.

The approach that works on microwaves and the fat layer
Onda is a procedure that uses 2.45GHz microwaves to act on both fat cells and the dermis.

InMode FX preheats the fat layer to 40 to 43 degrees with RF and then delivers high-voltage pulses (HVP) to induce damage to the fat cell membrane.
This is recommended for those whose line is collapsed by fat volume, such as a double chin, submental fat, and sagging cheek flesh.
It is a safety-focused device with a set temperature limit, so it is hard to expect a dramatic change from a single session, and accumulating energy is the key.

Choices that vary by layer
Which procedure suits you within the category depends on the layer where the sagging occurred and the area of concern.
Ultherapy works on the deep layer, and the texture and firmness of the surface layer is a separate domain, so the layers do not overlap.
That is why many people combine it with procedures that work on the surface layer, such as Density, Onda, and TenTherma, and the combination varies with skin condition.
Kkeut Oriental Medicine Clinic sets the design first in a seated position before lifting procedures.
This is because when you lie down, the direction of gravity changes and sagging tissue is pushed back and up, so a face lying down looks less sagging than it really is.
Kkeut Oriental Medicine Clinic touches and visually checks the face to understand skin thickness by area, then plans before starting where to use the 4.5mm tip and where to go with 3.0mm.

Ultherapy at Kkeut Oriental Medicine Clinic includes a tilting skill in which the tip is angled while confirming the layers on the ultrasound screen.
The tip depth is fixed, so if the SMAS layer is at 3.8mm, the 4.5mm tip passes below it and the 3.0mm tip passes above it.
In that case, tilting the tip diagonally changes the actual depth where the focus forms, reaching layers between the tip specifications.
This adjustment is a time-consuming process, but Kkeut Oriental Medicine Clinic spends that time.
One shot of Ultherapy is not a point but a line, and its standard length is 25mm. Kkeut Oriental Medicine Clinic treats with the 25mm standard length and shows you the device setting screen before the procedure.

After the procedure, you receive a lifting card.
It records which tip was used, how many shots were delivered to which area, and how the intensity was set for each area, serving as a reference for the next procedure.

Frequently Asked Questions
Q. Is one session of a skin firming laser enough?
A. The interval differs by skin firming laser procedure. For Ultherapy, if the recommended number of shots was fully received, we guide an interval of 6 months to 1 year; if the shots fell short and are divided, we guide filling them in at 1-month intervals. For Shurink, cumulative treatment at 1-month intervals, and for InMode FX, periodic treatment of about 5 sessions are presented as supported. It varies with the degree of sagging, so a consultation is needed.
Q. Do skin firming lasers hurt a lot?
A. Among skin firming lasers, Ultherapy delivers energy to deep layers and causes some stimulation, but most people receive it with numbing cream, and we do not recommend sedation. The energy must be delivered with the tip in close contact, and if the head moves during sleep, the delivery position shifts. InMode FX does not use numbing cream because of the burn risk.
Q. Where should I start with the types of skin firming lasers?
A. The types of skin firming lasers become clear when you sort them by the layer of sagging and whether there is fat volume. If the whole line has sunk, look at the ultrasound category; if the surface-layer firmness is the concern, the radiofrequency and microwave category; and if fat is weighing down the line, InMode FX. Kkeut Oriental Medicine Clinic decides together with the design at the consultation.
