Density lifting in Daegu — everything to know before treatment, in one place
Miso Clinic’s writing on Density is spread across several pages: the product reference, comparisons, shot counts, side effects and recovery. This column is the first page to read if you are looking into Density in Daegu: each question gets a short answer and a link to the detailed page.
The short answer
Density is a radiofrequency (RF) lifting device made by Jeisys Medical that delivers monopolar and then bipolar RF in sequence, treating different depths one after the other. Miso Clinic considers Density first for early-to-moderate sagging, where the jawline has blurred and the cheeks have dropped, and not first when the main problem is lost volume or thin, dull skin. The only human data on Density is one case series of 16 Japanese adults · one session · 24 weeks with no control group (tightening 0.82 mm, pain 1.4/5, no burns reported). Density results are judged two to three months after treatment. Miso Clinic is in Jung-gu, Daegu, at Exit 1 of Kyungpook National University Hospital Station.
What kind of lifting device is Density? At a glance
| Item | Details |
|---|---|
| Density manufacturer | Jeisys Medical (South Korea) |
| Density delivery | Monopolar → bipolar RF in sequence (manufacturer: patented sequential heating) |
| Density safety features | Five-level gas cooling · RIC automatic impedance adjustment · real-time skin temperature display |
| Density tips | Four: ALPHA · Eye · Face · Body (guaranteed shots 600 · 600 · 1,000 · 600) |
| Density approval in Korea | Medical device approved by Korea’s Ministry of Food and Drug Safety (MFDS, the national regulator of medicines and medical devices) — we could not verify the approval number in the original record |
| Density human data | One case series · 16 people · one session · 24 weeks, no control group |
| What Density treats | Sagging · jawline · firmness — the dermis and the structure beneath it |
| What Density does not treat | Lost volume, pigmentation, removal of excess skin |
We found no comparative trial showing that Density’s sequential delivery gives better results than a single mode. The sequence explains how Density was designed; it is not evidence of superiority.
Which faces does Density suit, and which does it not?
| This situation | Density decision | Why |
|---|---|---|
| Jawline blurred, cheeks feel lower | Consider Density first | Sagging is what RF treats |
| Thicker skin with deeper sagging | Consider Density first | Density is designed to treat deep and shallow layers in sequence |
| Texture and density already treated with injectables, sagging remains | Consider Density | Density works on a different layer |
| Hollow cheeks or temples | Density not recommended | Heat does not create volume |
| Thin, dull skin is the main problem | Another category before Density | Skin boosters · collagen boosters |
| Pacemaker, defibrillator or other implanted electrical device | Density generally avoided | RF uses electrical current |
| Skin so lax it folds | Density not recommended | Beyond the range of non-surgical devices |
How Miso Clinic divides cases between Density and other devices is set out in Density vs XERF in Daegu and choosing between Oligio Kiss, Density and XERF.
How far have Density results been confirmed?
| Item | Details |
|---|---|
| Density study population and design | 16 Japanese adults (1 man · 15 women, mean age 49.4) · one session · 24 weeks · no control group · single author |
| Density treatment dose | About 500–600 shots in one session |
| Density results | Tightening 0.82 mm, lower-face thickness −0.89 mm, GAIS improved in 15 of 16 |
| Density pain and adverse events | 1.4/5; no burns, persistent erythema or scarring reported |
The Density paper’s conclusion uses the phrase “clinically proven”, but Miso Clinic does not repeat it, because a 16-person case series without a control group cannot carry that claim. Why the missing control group matters is explained in why some reviews say Density and XERF did nothing.
Density pain, shot count, recovery, duration and side effects
- Density pain — a hot sensation rises briefly and fades, over and over. Areas close to bone or with thin skin are more sensitive, and numbing cream is used depending on the area. Heat you cannot bear during Density is a safety signal to tell us about, not something to endure.
- Density shot count — Density shots are a fixed allocation sealed into each tip, so the count is set by the area and number of regions. No human study has randomly compared 300 and 600 Density shots (Density 300 shots versus 600).
- Density recovery — the tight feeling right after Density is immediate contraction plus swelling; results are judged at two to three months (the first three months after Density or XERF).
- How long Density lasts — the Density data follow people for only 24 weeks, so we do not promise a number of months (how long Density and XERF last).
- Density side effects — burns appear within 72 hours and fat atrophy at one to four months, so there are two periods to watch (Density and XERF side effects and burns).

Density in Daegu: frequently asked questions
What kind of lifting is Density?
Density is a radiofrequency lifting device made by Jeisys Medical that delivers monopolar and then bipolar RF in sequence to heat the dermis and the structure beneath it. Density aims at sagging, jawline and firmness; it does not add volume.
Have Density results been proven?
The human data on Density is one case series of 16 people followed for 24 weeks, reporting 0.82 mm of tightening and improvement in 15 of 16, with no control group. For that reason Miso Clinic does not describe Density as “clinically proven”.
Does Density hurt?
Density produces short, repeated waves of heat. The Density study reported a mean pain score of 1.4/5, but how it feels varies with area and settings, and areas close to bone are more sensitive. Numbing cream is used depending on the area.
How many Density shots do I need?
The Density shot count is set by the area and the number of regions treated. The Density study used about 500–600 shots in one session, but no human study has randomly compared shot counts, so there is no basis for saying more Density shots are better.
How long do Density results last?
The Density data follow people for 24 weeks. For RF lifting in general a peak at four to six months has been reported, but those are not Density data, so the timing of the next Density session is decided from the state of the face.
Can I wear make-up and go to work on the day of Density?
Non-invasive RF such as Density does not break the epidermis, and clinical trials advised immediate return to normal activity and usual cosmetics. Redness after Density can last from a few hours to a day.
Should I choose Density or XERF?
No study has compared Density and XERF directly in people. Miso Clinic starts from the face: Density first when the skin is thicker and the sagging deeper, XERF first when avoiding anaesthesia and returning to normal the same day matter most (clinical judgement).
How is Density different from Thermage?
Density and Thermage both belong to the 6.78 MHz monopolar RF family, but Density adds bipolar RF in sequence, and the body of evidence for Thermage is far larger. No direct comparison study exists, and Miso Clinic does not have Thermage.

- Thermage — Solta Medical, 6.78 MHz monopolar, device registered with the US FDA. There are many publications, but most are uncontrolled observational studies or physician surveys, and a 2020 international Delphi consensus noted that device-specific guidance is lacking.
