What Is Density Dual RF?
Density is a radiofrequency lifting device that delivers monopolar RF and bipolar RF at the same time through a single handpiece. Its operating frequency is 6.78MHz and its maximum output is 400W. Because it targets the deep layer of the skin (lower dermis) and the shallow layer (epidermis and upper dermis) with separate energy, its energy pathway differs from that of single-mode RF devices.
The Density used at Repic Clinic in Gangnam also comes with a five-level gas-spray cooling system, which manages epidermal temperature during treatment.
STEP 1 — Monopolar RF: Delivering Energy to the Deep Layer
- Setting the energy pathway
In the monopolar method, RF energy generated at the handpiece (positive pole) travels through the body to a grounding pad (negative pole) on the other side. Because this path is long, the energy reaches the deep layers of the skin. - Heating the lower dermis
RF energy meets resistance in the tissue and is converted to heat. When collagen fibers in the lower dermis receive this thermal stimulation, they contract right away, and over the following weeks new collagen production begins. - Result
This is the step that builds the elasticity foundation across the full thickness of the skin. It mainly comes into play when loss of lower-dermal volume is the main concern, as in sagging of the cheeks, jawline and forehead.
STEP 2 — Bipolar RF: Precise Stimulation of the Shallow Layer
- Switching the energy pathway
In the bipolar method, the RF current flows only between the two electrodes (positive and negative) in the handpiece. Because the distance between the electrodes is short, the depth reached by the energy is concentrated in the epidermis and upper dermis. - Heating the layer near the surface
Heat is distributed evenly in the shallow layer, acting on fine lines, skin texture and surface elasticity. At the same time, stimulation also reaches the tissue around the sebaceous glands and pores. - Result
Improvement of surface texture and reinforcement of elasticity take place in this step. While the monopolar mode works down deep, the bipolar mode complements the upper layers.
STEP 3 — The 6.78MHz Frequency and Simultaneous Dual Delivery
- The role of frequency
As RF frequency goes higher, tissue resistance decreases and the energy penetration characteristics change. Density uses 6.78MHz to achieve stable energy distribution in both modes. - What simultaneous delivery means
When monopolar and bipolar run at the same time rather than in sequence, the deep and shallow layers can be stimulated twice over within a single treatment time. Unlike single-mode RF devices, there is no need to choose just one depth. - What the 400W maximum output means
A higher output does not automatically mean a greater effect. 400W is the upper limit at which the device can operate, and in actual treatment it is adjusted according to skin thickness, area and response. At Repic Clinic in Gangnam, the output suited to your individual conditions is decided through a consultation.
STEP 4 — Five-Level Gas-Spray Cooling
- Why cooling is needed
RF energy also generates heat in the epidermis. If the epidermal temperature rises too much, there is a risk of redness, swelling and burns. Cooling is a mechanism for both protecting the epidermis and making treatment more comfortable. - Adjusting in five levels
Density's gas-spray cooling adjusts intensity in five levels. Stronger cooling is applied to areas with thin skin, such as around the eyes, or areas with high heat sensitivity, and a lower level is applied to thicker areas such as the cheeks. - Temperature management during treatment
The cooling intensity can be changed in real time by area during treatment. This structure is what makes it possible to treat various areas in succession within a single session.
Summary of What to Check Before Treatment
| Item | Details |
|---|---|
| Device name | Density |
| Energy method | Monopolar + bipolar dual RF, simultaneous |
| Frequency | 6.78MHz |

Understanding the steps above in order helps you see how Density differs structurally from simple "radiofrequency lifting." Three flows are bundled into one treatment: monopolar secures depth, bipolar complements the shallow layer at the same time, and five-level cooling manages epidermal temperature. The output and cooling settings suited to your skin condition and treatment goals are best confirmed through a consultation.
Frequently Asked Questions
Why does Density dual RF use monopolar and bipolar at the same time?
Monopolar RF energy travels a long path through the body, so it reaches the deep layer of the lower dermis, whereas bipolar RF current flows only between the two electrodes in the handpiece, so it is concentrated in the shallow layer of the epidermis and upper dermis. When both run at the same time, the full range of skin depth can be stimulated twice over within a single treatment session. Single-mode RF has to choose just one depth, but Density does not have this limitation.
How do Density and InMode lifting differ?
InMode is a device that combines bipolar RF with vacuum suction and specializes in tightening specific areas such as the jawline and cheeks; its burden per session is relatively low, so it is often used for regular maintenance. Density differs in that it covers both deep and shallow layers at the same time with monopolar plus bipolar dual output. Which device is suitable depends on your skin condition, area of sagging and goals, so it is recommended to confirm this at a consultation.
Are there precautions after Density treatment?
After RF-type treatments, temporary redness, swelling and a sensation of warmth may generally appear, and most ease within a few days. Right after treatment, it is recommended to avoid strong UV exposure and to keep up thorough sun protection. Reactions may differ depending on your individual skin condition, so you should confirm the exact precautions with your medical team before treatment.
