Not the treatment in fashion —
the treatment you need, performed by specialists

Grays Dermatology is located on the 10th floor of L Tower, 6 Jwadong-sunhwan-ro, Haeundae-gu, Busan, and is staffed entirely by board-certified dermatologists. The clinic is directly in front of Exit 8 of Jungdong Station on Busan Metro Line 2.

It is easily reached from Marine City and Centum City, and it is close to Haeundae Beach, Mipo, Songjeong and Osiria in Gijang, so visitors travelling in eastern Busan or staying at nearby hotels can come in easily. The Haeundae intercity bus terminal is also nearby, which makes public transport from outside Busan convenient.

If you come by car, you may use the tower parking facility inside the L Tower building. If tower parking is not suitable for your vehicle, the nearby Jungdong Station public parking lot is available.

For details on parking or directions, please contact the clinic at +82-51-710-1891.

Evening hours on Tuesday and Friday make it possible to visit after work, and Saturday runs without a lunch break for those who cannot come on weekdays. Hours and closures may change, so please check our website or call the clinic before visiting.

Same-day appointments and walk-in visits are both possible, but waiting times can be long depending on the schedule and the treatment you want, so we recommend booking in advance where possible.

You can book by phone (+82-51-710-1891), through our KakaoTalk channel or via Naver TalkTalk, and you are welcome to ask about same-day availability. International patients can book and adjust their schedule from overseas through WeChat, LINE or Google Reservations.

Lifting procedures such as Thermage FLX and Ulthera, and any treatment that requires anaesthetic preparation, need sufficient consultation and treatment time. Booking ahead shortens your wait and allows the session to run smoothly.

If you visit without an appointment we will try to see you, but same-day treatment may not be possible depending on the schedule and the procedure you choose.

Ulthera uses high-intensity focused ultrasound (HIFU) to concentrate energy at a chosen depth beneath the skin, focusing on lifting sagging tissue at deeper layers. Thermage FLX delivers monopolar radiofrequency (RF) energy broadly across the skin to induce collagen contraction and regeneration, focusing on elasticity and tightening. Put simply, Ulthera is closer to 'lifting at depth' and Thermage to 'overall skin tightening'.

In practice, however, what matters more than comparing which treatment is better is how the two energies should be applied to each individual. The degree of ageing, the thickness of the skin and subcutaneous fat, the direction and location of sagging, overall facial contour, and the change you most want to see all have to be considered together.

Two patients of the same age with similar sagging may need different approaches: one may benefit from a greater share of ultrasound lifting, while another may achieve a more natural result with RF tightening as the mainstay. In some cases combining the strengths of both is the most effective option.

At Gray's, a board-certified dermatologist examines your facial structure and pattern of ageing directly, then designs the role and proportion of Ulthera and Thermage individually. This difference in treatment design is what shows up in the result and in patient satisfaction.

'Ulthermage' is the term commonly used for combined lifting in which Ulthera and Thermage are performed together.

Ulthera delivers focused ultrasound (HIFU) energy to a target depth beneath the skin, while Thermage delivers monopolar RF heat more broadly through the skin and subcutaneous tissue. Because their delivery methods and treatment goals differ, the two are complementary, and pairing them is one of the representative strategies for addressing several facial layers at once.

What matters, however, is not selecting the specific 'Ulthera + Thermage' pairing. It is judging which part of your face needs which energy at which depth, and then distributing the roles and energy of HIFU and monopolar RF accordingly.

This also means a limited budget does not force you to choose only one. Within the same budget, different HIFU and monopolar RF pairings can be considered according to your skin condition and the depth of treatment required — for example XERF + V-RO, Oligio + Ultherapy, or Oligio + V-RO. Where deeper lifting is needed, the share of HIFU is increased; where elasticity and tightening are needed, the share of monopolar RF is increased.

Ultimately, good lifting is not defined by a device name or a shot count. Rather than applying a fixed 'Ulthermage' package uniformly, we design the type of device, the treatment area and the energy distribution individually, taking into account skin thickness, subcutaneous fat, the location and direction of sagging, facial contour, the change you want and your budget.

Tune Face uses the radiofrequency (RF) technology of the Accent Prime platform for purposes such as skin elasticity, tightening and improvement of facial contour. Accent Prime supports several handpieces based on RF and ultrasound technology, so rather than repeating an identical treatment with one device, the required energy and handpiece can be selected according to skin thickness, fat distribution, loss of elasticity, scarring and the area being treated.

For example, Tune Liner (MiniSpeed) can be used for contour improvement where a double chin or localised fat is a concern; UniLarge delivers RF energy over broader areas for elasticity and skin texture; and the Microplasma technology of Legato is used for acne scarring and irregular skin texture.

At Gray's we use Accent Prime on its own, in combination with other energy-based lifting such as Ulthera and Thermage, or as part of a pre-heating step that warms the required area sufficiently in advance. The point is not to apply a particular handpiece uniformly, but to assess skin thickness, fat distribution and the direction and degree of sagging, then distribute the appropriate energy to the required area and depth.

Fillers use substances such as hyaluronic acid to create volume and structural support directly where it is needed. They are often more suitable beneath the retaining ligaments, where tissue needs to be held up, or in areas such as the nose and chin where a defined shape and contour is required.

Collagen boosters, rather than filling space, prompt the skin and soft tissue to form their own collagen. Instead of building up a specific point, they are used to improve broad areas of hollowing such as the cheeks and temples, along with loss of elasticity and density, in a more natural way.

Skin booster is a broader term still. Depending on the product and its ingredients, the goal may be regeneration, hydration, skin texture or elasticity. Rejuran, whose main aim is to improve the skin environment and its regenerative capacity, and Juvelook, which induces collagen production more actively, are both called skin boosters, yet their actual roles and purposes differ.

The question is therefore not which is better, but what needs to be improved. Where structural support and contour are needed, a filler; where natural volume across a broad area and collagen recovery are needed, a collagen booster; where skin texture, hydration and regeneration are the issue, a skin booster suited to that purpose — or a combination.

Rather than injecting large volumes of whatever ingredient is currently in fashion, we first determine what your skin lacks and which function needs to be restored, then combine ingredients with different roles so that hydration, regeneration and collagen formation support one another. Our aim is that your skin remains healthier than before treatment even after the direct effect of the injected material has faded.

Juvelook Volume is a collagen booster that uses PDLLA to induce collagen production in the skin and soft tissue, gradually restoring volume where it has been lost.

Unlike hyaluronic acid fillers, its main purpose is not to create immediate shape and volume through the injected material itself; instead it induces collagen formation over time, which makes it well suited to improving broad areas of hollowing such as the cheeks and temples naturally. Where a defined contour or structural support is required, as at the nose or chin, a filler may be more appropriate.

With PDLLA collagen boosters, how the product is prepared and hydrated before treatment matters as much as which product is used. Preparing the material so that the PDLLA particles are fully and evenly dispersed improves the uniformity of the treatment and reduces the possibility of side effects such as nodules, while supporting the intended tissue response and collagen formation.

For this reason we do not hydrate Juvelook hurriedly on the day and treat immediately, nor do we prepare product in bulk for multiple patients in advance. Once your appointment is confirmed, your name and the hydration start date are recorded separately and hydration of a vial for you personally is begun in advance. Product that has gone through a sufficient preparation period is used only for the patient it was booked for, and if that treatment does not take place it is discarded rather than used for anyone else.

Because sufficient hydration time must be secured, Juvelook Volume requires booking at least one week in advance. We believe that how the product was prepared and into which area and layer it was injected matters far more than 'how many vials were used'.

Ultracol is a collagen booster made from PDO (polydioxanone), long used in medical sutures, in the form of fine particles. As the injected PDO particles break down slowly in the body, they induce collagen formation in the surrounding tissue, improving skin elasticity and density, fine lines and hollowing in a natural way.

It can be used under the eyes and on the forehead. These areas call for a more precise approach because the skin is thin and the anatomy delicate, but with the right concentration and injection plane, Ultracol can be used to improve thinning skin and fine lines under the eyes, and loss of elasticity and subtle hollowing on the forehead.

Ultracol is not appropriate for every case of under-eye hollowing or forehead volume loss. Under the eyes, protrusion of orbital fat, the depth of the tear trough, ligament structure and midface volume loss all contribute alongside skin thickness, so depending on the cause a filler, a different collagen booster or a lifting treatment may be more suitable.

Ultracol is likewise never simply mixed immediately before treatment; as a matter of principle it goes through a sufficient hydration process. Once your appointment is confirmed, your name and the hydration start date are recorded and hydration of a vial for you personally is begun in advance. Prepared product is used only for that patient, and is discarded rather than used for anyone else if the treatment does not take place. Ultracol therefore requires booking at least five days in advance.

At Gray's we design the concentration, injection depth and volume of Ultracol individually, taking into account skin thickness, fat and skeletal structure, the location and depth of hollowing, and movement with facial expression.
