Density

DENSITY is an RF treatment device that can improve skin sagging and wrinkles using RF (radiofrequency). By heating the skin and subcutaneous tissue with high-frequency RF at 6.78MHz, it contracts collagen fibers in the dermis and fibrous septa in the subcutaneous tissue,
providing skin tightening and facial contouring effects. Furthermore, the heat stimulates fibroblasts in the dermal layer, and during the process of contracted collagen repair, collagen and elastin are generated, resulting in improved skin quality. This treatment is recommended for those who wish to address wrinkles and sagging
without surgery.
A distinctive feature is its high effectiveness even after a single treatment, as it delivers heat deep into the tissue while cooling the skin surface with gas.

Recommended for those who:

  • Those concerned about age-related sagging
  • Those concerned about facial fat
  • Those who wish to improve a double chin
  • Those who wish to simultaneously improve skin firmness and radiance
  • Those concerned about pores

Features of Density

Effects of DENSITY

As we age, facial skin begins to sag. The causes of sagging are multifaceted, including the descent of cheek fat and decreased elasticity in the dermis. DENSITY achieves skin tightening by contracting collagen fibers in the dermis and fibrous septa in the subcutaneous fat layer using RF energy.
Additionally, due to aging and photoaging, the function of fibroblasts that produce collagen and elastin—the sources of skin firmness, moisture, and elasticity—declines, leading to a reduction in collagen and elastin. During the repair process of collagen fibers contracted by DENSITY’s thermal energy, fibroblasts are stimulated, generating new collagen and elastin, resulting in improved skin firmness and radiance. This effect can last up to 6 months.

Latest Technology: Patented Monobi Technology

Density is equipped with a patented Monobi system. This is a specialized irradiation system in which monopolar irradiation is followed by continuous bipolar irradiation in a single shot. By preheating the skin layer with monopolar irradiation, the heat from the subsequent bipolar irradiation is transmitted more efficiently, providing enhanced treatment of skin sagging and wrinkles compared to using monopolar RF alone, with expected improvement in skin quality after treatment.

Cooling System

DENSITY is equipped with a gas cooling system adjustable across 5 levels. By irradiating cooling gas before, during, and after treatment to cool the skin surface, it alleviates pain during the procedure and reduces the risk of burns on the skin surface while delivering strong thermal energy deep into the tissue.
Additionally, DENSITY’s handpiece is equipped with a temperature sensor, enabling accurate measurement of skin temperature during treatment. This allows for precise and safe treatment.

Confirming Skin Condition with Each Shot and Delivering Uniform Energy

Skin thickness and fat volume vary from person to person. Consequently, skin-to-subcutaneous resistance (impedance) also differs for each individual. While conventional lift-up machines measured skin resistance only during the initial shot, DENSITY measures skin resistance in real time with each shot. This enables the delivery of the optimal amount of radiofrequency energy to the skin at each step of treatment, allowing procedures tailored to each patient’s skin condition.

Thread Treatment

Recommended for those who:

  • For those concerned about nasolabial folds or sagging around the mouth
  • For those whose facial contours have become less defined
  • For those who want to reduce volume in the lower half of the face, even at a young age
  • For those who were not satisfied with lift-up devices such as Thermage or HIFU
  • For those who want to feel the lifting effect immediately after treatment
  • For those who cannot afford long downtime or are hesitant about surgical treatments (facelift surgery)

Thread Lift Using Non-Surgical “Dissolvable Threads”

Sagging becomes a concern with age. In particular, when the area around the eyes, nasolabial folds, mouth, and under the chin begin to sag, it can create an aged or tired appearance, which concerns many people.
At our clinic, we perform thread treatments (thread lifts) to lift facial sagging using “dissolvable threads” called PDO.
Thread treatment is a sagging treatment using special “needles” and “dissolvable threads” without using a scalpel. Since it is performed only with needles without incisions, the only marks are needle punctures. Downtime is significantly reduced compared to conventional surgery, and the results are very natural.

To treat facial sagging, it is important to:
① Lift the descended fat upward
② Firmly reinforce the loosened ligaments
③ Stimulate collagen production to restore skin firmness and elasticity

① To move descended fat upward, we use special “dissolvable threads” with barbs (cogs). The barbs catch on the subcutaneous tissue, firmly lifting the sagging and moving the descended fat upward.
(Anti-Gravity Thread・Tes Lift Soft)
②③ Decreased collagen is a major factor in sagging. As the dissolvable threads are absorbed, they stimulate blood vessels and the dermis, promoting collagen production. By inserting many “dissolvable threads,” tightening effects on loosened ligaments and subcutaneous tissue, as well as improvement in skin firmness and radiance, can be expected.
(Tightening Thread・Derma Spring Eye・Tes Lift Soft・Scaffold)

There are various types of thread treatments depending on the thread material and the presence or shape of barbs (cogs), but our clinic only uses highly safe “dissolvable threads” that are broken down and absorbed by the body. Since no foreign material remains in the body, you can receive treatment with peace of mind.

As part of our commitment to thread treatment, we actively participate in domestic and international training sessions and research the latest techniques. We also regularly review the threads themselves and incorporate safer and more effective options.
Furthermore, sagging cannot simply be lifted. Comprehensive sagging treatment tailored to each patient’s skin quality, bone structure, fat, and muscle condition is necessary.
At our clinic, we propose natural and comfortable sagging treatments based on thread treatment, combined with hyaluronic acid injections to add volume where needed, and lasers to improve skin quality and promote collagen production.

Anti-Gravity Thread (Lifting)

  • For those concerned about nasolabial folds or sagging around the mouth
  • For those with excess fat who want a smaller face
  • For those whose facial contours have become less defined

Anti-Gravity Thread is a thread made of body-absorbable material (PDO thread) used in surgical procedures, with specially processed barbs (cogs). When this thread is inserted into the subcutaneous tissue using a special needle, the barbs catch on the loosened fascia and fat, firmly lifting and tightening the loosened tissue against gravity.

Characteristics and Progress of Thread Treatment Using “Dissolvable Threads”

Lifting with Anti-Gravity Thread uses a cannula, a needle with a rounded tip, to insert the threads subcutaneously, resulting in minimal pain and almost no visible scarring beyond needle punctures. You can feel the naturally lifted effect immediately after treatment. The inserted threads are absorbed by the body over approximately six to eight months, and the direct lifting effect gradually diminishes.
However, the insertion of barbed threads activates the surrounding cells. The effect of plumping the skin from within through increased collagen and fibrosis means it does not completely return to its original state.

Summary of Anti-Gravity Thread Characteristics

  • Immediate results as dissolvable threads with special barbs (cogs) directly lift without using a scalpel
  • Excellent fixation power from barbs (cogs)
  • Superior elasticity for natural results
  • Safe and secure threads that are absorbed by the body in six to eight months
  • Cell activation around threads & collagen proliferation, tightening effect, and skin firmness
  • Scarring limited to needle punctures
  • Daily activities (makeup) possible from the next day

Tes Soft Lift (Tes Thread) (Lifting & Tightening)

  • For those concerned about nasolabial folds or sagging around the mouth
  • For those with excess fat who want a smaller face
  • For those whose facial contours have become less defined

Tes Soft Lift (Tes Thread) is an absorbable thread (PDO thread) with a special structure integrating a 3D mesh and barbs.
The barbs catch on the subcutaneous tissue, firmly lifting the sagging, and the gaps in the 3D mesh serve as scaffolding for collagen proliferation, providing not only strong lifting but also excellent tightening effects.
The threads themselves are absorbed in approximately six to eight months, but due to strong collagen production effects, the lifting effect is said to last approximately one and a half to two years.
After treatment, there may be swelling and edema for several days. For several days to about one month after the procedure, you may experience tightness or discomfort when opening your mouth wide, laughing, or washing your face. Internal bleeding may also occur, but all of these will become less noticeable over time.

Anchor Plus (Lifting)

  • For those who want to firmly lift the cheek area
  • For those whose facial contours have become less defined
Anchor Plus is an absorbable thread using a dissolvable material called PDO (Polydioxanone).
Compared to the conventional Anchor product, the cog length is doubled, the number has increased, and the strength is approximately doubled, providing a stronger sagging lifting effect.
It delivers a strong lift-up effect immediately after treatment.

Tightening Thread (Tightening)

  • For those concerned about nasolabial folds or sagging around the mouth
  • For those concerned about uneven skin tone or dullness
  • For those whose facial contours have become less defined

Tightening Thread is a thread treatment that inserts ultra-fine absorbable threads (PDO threads) thinner than hair in a vertical and horizontal net pattern without barbs, increasing collagen in the inserted area and tightening.
It is suitable for tightening marionette line bulges around the mouth and looseness from the facial contour to the neck that cannot be fully lifted with Anti-Gravity Thread alone. The inserted threads are absorbed by the body over approximately eight months, and the tightening effect continues gradually thereafter.

Eye Thread (Derma Spring Eye)

  • Non-surgical improvement of wrinkles and sagging under the eyes

Until now, there were no good non-surgical methods for improving under-eye puffiness, sagging, wrinkles, and crow’s feet that become prominent with age.

However, with the introduction of Eye Thread (Derma Spring Eye), non-surgical treatment for eye area sagging has become possible.
Eye Thread inserts absorbable threads (PDO threads) specifically designed for the eye area into sagging and fine lines around the eyes to increase collagen and elastin, tightening and improving under-eye puffiness, sagging, and fine lines.
The needle used to insert Eye Thread has a rounded tip (blunt needle) and is designed to minimize bruising even on the thin skin around the eyes (although bruising may still occur).

SonoQueen (HIFU)

A ‘non-surgical skin tightening treatment’ that uses the power of ultrasound to effectively target the SMAS layer (superficial musculoaponeurotic system) and dermal layer, the root causes of sagging!

Recommended for those who:

  • Improve sagging without downtime
  • Lack of skin firmness
  • Concerned about wrinkles
  • Do not wish to undergo treatments involving scalpels, needles, or implants

What is SONOQUEEN

SONOQUEEN is the latest skin tightening device utilizing HIFU (High-Intensity Focused Ultrasound). HIFU energy is also utilized in cancer treatment.
Lift-up machines utilizing HIFU energy are characterized by their ability to avoid damaging the skin surface.
Among these devices, SONOQUEEN employs original cartridges that accurately deliver heat of 60–70°C from the dermal layer to the SMAS layer (superficial musculoaponeurotic system), which causes sagging. While an immediate contraction effect occurs at the treated area, collagen production continues over 1–3 months, resulting in both internal lift-up and skin tightening effects.
At our clinic, trained practitioners carefully perform treatments using three types of cartridges—4.5 mm, 3.0 mm, and 2.0 mm—selected according to the treatment area and target depth.

Three types of cartridges target each layer!

4.5 mm: Targets the SMAS layer (superficial musculoaponeurotic system)!

Thermal energy is delivered to the SMAS layer, a fascia that supports the skin beneath the dermal layer. Damaged proteins contract tightly, tightening the laxity in both the dermal and SMAS layers, resulting in a lift-up effect.

3.0 mm: Activates collagen in the dermal layer!

Thermal energy damages fibers within the dermal layer, but the wound-healing process that repairs the damaged fibers activates collagen regeneration, enhancing firmness and elasticity. A further tightening effect is felt over the course of one month.

2.0 mm: Eye Shadow HIFU!

HIFU thermal energy is delivered to delicate areas with thin skin and curves, such as around the eyes, under the eyebrows, and the forehead, which were difficult to treat with conventional technology.
A dedicated mini cartridge for SONOQUEEN targets superficial wrinkles.

Features of SONOQUEEN

  • Heat accurately reaches the targeted layer with minimal pain
  • The 2.0 mm mini cartridge enables detailed treatment around the eyes
  • No downtime, with naturally noticeable results
  • 40–50 minute treatment with effects lasting approximately 6 months to 1 year

Eye Shadow HIFU

At our clinic, we use a dedicated Eye Shadow HIFU cartridge with a 5.0 mm irradiation opening to perform detailed treatment around the eyes and forehead. It is possible to irradiate up to the very edge of the bone for wrinkles and sagging above and below the eyes and eyebrows, as well as on the forehead. SONOQUEEN’s unique cartridge, which delivers thermal energy to a depth of 2.0 mm, enables accurate irradiation even in areas with thin skin or near nerves. Patients who wish to avoid injection or filler treatments around the eyes can receive this treatment with confidence.
