Density Alpha Tip, The Principle of Two Different Energies | Gangnam Station Dermatology

When receiving consultations for high-frequency (RF) lifting, there is one thing you hear particularly often about Density. 

It is the explanation that it "uses two types of energy."

This can easily sound like it alternates between strong and weak energy, but that is not the case. 

At Secret Clinic, we also clarify this part first during Gangnam Density consultations.

The two types are about the path, not the intensity

High-frequency works by sending an electric current through the tissue. Heat is generated as the tissue resists the flow of the current. It is a structure where heat is created within the tissue, rather than applying heat from the outside.

Here, the method differs depending on where the current enters and exits.

Monopolar (monopolar) current travels a long way around. 

There is one electrode on the treatment side, and a large pad is attached elsewhere on the body. The current enters through the electrode, passes through the body, and exits through that pad. The path it travels becomes longer.

Bipolar (bipolar) current escapes right next to it. 

Two electrodes are placed close together, so the current flows only between them. No separate pad is required. The path it travels is short.

Different paths mean different depths reached

Since heat is generated where the current passes, a deep path warms the deep layers, and a short path warms the shallow layers.

Literature summarizes this difference as follows. The monopolar method is reported to reach relatively deep layers, while the bipolar method is described as being limited to a depth of approximately half the distance between the electrodes. This means that if the electrode spacing is narrow, it acts that much shallower.

Therefore, bipolar does not go deeper just by increasing the output. This is because the shape of the path determines the depth. 

This is why these two methods should not be understood as "strong and weak."

What it means that the Alpha Tip supports both

Based on manufacturer data, the Density Alpha Tip is a tip designed to support both monopolar and bipolar high-frequency methods, and it is introduced as having a larger electrode area than previous tips. The equipment description states that technology for sequentially irradiating monopolar and bipolar energy is applied.

In summary, it means that deep and shallow layers can be treated separately in a single session. It is closer to combining two separate treatments into one.

However, the fact that the electrode area has increased means that the range reached at once has widened, not that it goes in stronger. These two are different stories.

Why tips are divided into several types

Density tips are divided into several types. 

Looking at the electrode areas listed in official materials shows why they are divided. The Alpha Tip and Face Tip are 2×2cm, the Eye Tip is 0.5×0.5cm, and the Body Tip is 5×3.2cm.

If a large electrode is applied to a narrow and curved area like the eye area, it will not touch the skin evenly. Conversely, treating a wide area with a small electrode takes a long time and is easy to overlap. Tips are not performance grades, but sizes tailored to the area.

Therefore, what you should hear in a consultation is not the name of the tip being used, but why that size was chosen for that specific part of your face.

Limitations and risks you should know

Since it is a treatment that uses heat, you may feel a hot or aching sensation during the procedure. Literature describes the monopolar method as having relatively more pain.

Mild redness or swelling may occur after the procedure and is usually reported to subside within a few hours. In rare cases, blisters or superficial burns have been reported, and the literature cites excessive energy settings or operator manipulation as the cause.

And there is one thing you must know. Deep anesthesia reduces the sensation of heat during the procedure. The patient telling the practitioner it is "hot" is a safety device to prevent overheating, and the literature points out that if that signal weakens, the risk of epidermal damage can increase. It is natural to want anesthesia due to concerns about pain, but it is better to be aware of this point and discuss it.

The changes obtained are not permanent. Aging continues even after the procedure. Also, if you have metal implants or a pacemaker in the treatment area, or if you are pregnant, you must discuss whether to proceed first.

Good things to check during a consultation

If you are comparing several dermatology clinics near Gangnam Station, it is practical to ask the following.

· Which of monopolar or bipolar do you plan to use primarily, and why? 

· What size tip will be used on which area? 

· How will anesthesia be performed, and how do you handle the reduction in heat sensation at that time? 

· Which areas do not need to be treated right now?

Consultations where you get answers to the last question are generally reliable. Secret Clinic also conducts consultations in this order.

Summary

Density's "two energies" refer to monopolar and bipolar high-frequency, and the difference between the two is not intensity, but the path the current takes.

A long path warms deep layers, and a short path warms shallow layers. The fact that the Alpha Tip supports both methods means that two layers can be treated separately at once.

And tip types are not grades, but sizes tailored to the area. Secret Clinic also chooses tips based on this standard. What needs to be decided in a consultation is not the equipment name, but which layer and which part of my face will be treated.
