Comfort Lifting (CoolSoniq · XERF) Comfort Lifting (CoolSoniq · XERF)

CoolSoniq and XERF — Two Lifting Options Chosen for Your Skin

The causes of sagging and the degree of lost firmness vary from person to person. At WayB, we assess skin thickness, facial volume, your desired changes, and pain sensitivity before choosing a lifting approach. This is a program that selects the treatment your skin needs, rather than a fixed package requiring both devices.

Cooling and adjustments to intensity and speed help reduce discomfort. Heat or pain may still be felt, and settings are adjusted while monitoring your skin’s response.

CoolSoniq — Ultrasound Lifting for Sagging Skin and Facial Contours

CoolSoniq is a lifting device that uses focused ultrasound together with a cooling function. It delivers energy to a depth suited to the area to manage skin sagging and elasticity.

Who Is It Suitable For?

• Those who want to discuss skin elasticity and sagging while also considering pain burden during the procedure
• Those who have had an uncomfortable experience with a previous lifting procedure and want to adjust the method and intensity
• Those who want to choose a device according to their skin condition and recovery schedule

What to Check Together Before the Procedure

We check the thickness of the skin and fat, the degree of hollowing, and any history of previous filler, thread, or energy-based procedures. Please also let us know if you are pregnant or breastfeeding, have inflammation or infection, or use an implantable electronic device. A particular device is not suitable for everyone, and the areas of application and feasibility are determined during the consultation.

How Does It Work?

CoolSoniq creates thermal coagulation points at the target depth using focused ultrasound, and utilizes the tissue response during the recovery process. The cooling function is designed to reduce heat accumulation on the skin surface.

1.5, 3.0, and 4.5mm are the focal depths of the cartridges. The actual position of the skin, subcutaneous tissue, and fascia differs by area and by individual. CoolSoniq does not have a real-time ultrasound imaging function, and the characteristics of various devices are considered together, including cases where imaging confirmation is needed.

What Are the Features of CoolSoniq?

ACC Cooling — Keeping the Skin Contact Area Cool

ACC (Active Conduction Cooling) is a technology that suppresses overheating of the ultrasound generator and cools the skin contact area. It is a function intended to protect the skin surface and reduce pain burden during the procedure. The stimulation actually felt varies depending on the area, settings, and individual sensitivity.

Pen Applicator — Adhering Closely Along Facial Contours

The pen-shaped applicator moves in close contact with contoured areas while delivering energy. The manufacturer describes the technology applied to the pen applicator as TDT (Thermal Diffusion Treatment). The treatment range and movement speed are adjusted considering the skin thickness and the position of bones and nerves.

Three Depths — Considering Tissue Condition by Area

The target depth is selected using 1.5, 3.0, and 4.5mm applicators. A deeper setting is not necessarily better for every area. The selection is made according to skin and fat thickness, existing hollowing, and the desired change.

How Is the Procedure Performed?

• Consultation: Checks the degree of sagging and skin thickness, and determines the applicator and shot count for each area.
• Anesthesia: The cooling function reduces the need for anesthesia, but topical anesthesia is used together if needed.
• Procedure: Energy is delivered by area, with the order adjusted for areas over bone. A signal to stop by raising a hand is agreed upon before starting.
• Calming: You go home after cooling and calming. Same-day return to daily activities is possible.

How Long Does the Effect Last?

The effect can last approximately 6–12 months, and this varies depending on skin condition, the treatment area, and individual response.

A higher shot count alone does not mean a longer-lasting effect. The timing of the next procedure is determined by checking skin sagging, elasticity, and the response to previous procedures together.

Recovery and Precautions

• Mild redness and swelling often subside within a few hours, but may remain for about 2–3 days. Recovery varies by individual.
• Avoid alcohol, saunas, jjimjilbang (Korean-style sauna/bathhouse), and strenuous exercise for about a week, and maintain sun protection and moisturizing.
• Light cleansing and makeup are often possible from the same day, but if skin irritation remains, please adjust according to the clinic’s guidance.
• Filler and thread lifting can be performed together on the same day. The scope and order of application are determined according to the treatment area and skin condition, and the schedule can be divided into separate sessions if needed.

Please Contact the Clinic If

• Blisters or oozing occur
• Sensation is dulled or facial expression feels unnatural
• Mild redness or pain persists for 7 days or more
• Redness, pain, or swelling rapidly worsens or is accompanied by a feeling of heat or fever, regardless of duration

How WayB Approaches This

• We adjust cooling, intensity, speed, and the order of treatment areas according to your skin’s response.
• We discuss the areas and scope of treatment with you, rather than ranking one device as better for everyone.
• Before we begin, we agree on a signal: raise your hand if the pain becomes uncomfortable.
• We provide consultations and procedures in a private room, with communication available in 4 languages.

CoolSoniq FAQ

Q. What kind of procedure is Comfort Lifting?

Comfort Lifting is WayB’s lifting program that uses cooling and adjusts the device, intensity, and speed to your skin condition to reduce discomfort. We choose between CoolSoniq and XERF according to your skin’s needs.

Q. What is the difference between CoolSoniq and Ultherapy PRIME?

Both procedures manage skin sagging and reduced elasticity based on the focused ultrasound (HIFU) principle, so there are some similarities in the expected changes. However, the treatment method and the pain felt can differ. CoolSoniq is designed to reduce pain burden during the procedure through its own cooling, while Ultherapy PRIME performs the procedure while checking tissue with real-time ultrasound imaging. The choice is made by considering skin condition, goals, and pain sensitivity together.

Q. How often should I receive this treatment?

Whether to repeat the procedure and the interval are determined by checking your response and recovery status. The same cycle is not applied to everyone, and previous procedures and important schedules are also considered.

Q. How is pain burden reduced?

The burden is lowered through cooling and individually adjusted intensity, speed, and treatment order. Anesthesia is used together if needed, and pain and post-procedure response vary by individual.

Q. Can I receive it on the same day as another lifting procedure?

Whether this is possible depends on the device, area, previous procedures, and recovery status. Combinations are made only when necessary, and the order and interval are determined during the consultation.

Q. How long does the effect last?

Roughly 6–12 months, though this depends on skin condition, the treatment area, and individual response.

A higher shot count does not by itself extend how long the effect lasts. Skin sagging, elasticity, and how you responded to previous procedures are checked together to time the next one.

Q. Can I receive it on the same day as filler or thread lifting?

After checking your skin condition and the treatment area, this can be performed together on the same day. The scope and order of each procedure are adjusted, and if there is swelling or inflammation, or if more time is needed for recovery, the schedule is planned across separate dates.

XERF — Dual-Frequency Radiofrequency Skin Tightening

XERF uses two radiofrequencies, 6.78 MHz and 2 MHz, to address skin firmness and facial contours. The range and intensity of thermal energy delivery are adjusted according to skin thickness, facial volume, and the area of concern. Variable pulses and cooling work together to reduce heat at the skin surface during treatment.

Summary at a Glance

What Is XERF?

XERF is a lifting device that uses monopolar radiofrequency at two frequencies. It delivers thermal energy to the skin to induce collagen contraction and remodeling, helping address skin firmness and wrinkles.

Even within the same face, some areas have thin skin and others have thicker skin; some need their volume preserved, while others have more pronounced sagging. XERF allows energy settings to be adjusted by area after assessing these differences.

Who Is It Suitable For?

• Those who feel their skin has become looser and less firm than before
• Those concerned about both fine lines and skin smoothness
• Those whose facial contours look less defined because of sagging around the cheeks and jaw
• Those who want care tailored to skin thickness and volume, rather than the same intensity across the whole face
• Those considering radiofrequency treatment for skin firmness who also want to discuss heat and discomfort during treatment

The suitable treatment varies with the cause and degree of sagging, skin thickness, and hollowing. When reduced skin firmness and volume loss are both present, we distinguish their causes before planning treatment.

What to Check Before Treatment

Please tell us before treatment if you have an implanted electronic device, such as a pacemaker, or metal implants in the treatment area. We also check pregnancy or breastfeeding status, inflammation, infection or wounds in the treatment area, altered sensation, underlying conditions, and medications.

If you have recently had filler, thread lifting, skin boosters, laser treatment, or radiofrequency treatment, please let us know when and where it was performed. Depending on skin condition and the device’s precautions for use, treatment may be restricted, or its area and timing may need to change.

How Does It Work?

6.78 MHz and 2 MHz — Delivering Heat at Two Frequencies

XERF uses 6.78 MHz and 2 MHz to deliver thermal energy to tissue. The heat stimulates collagen within the skin, and the subsequent remodeling process helps improve firmness.

We distinguish thin-skinned areas from areas with more pronounced sagging and choose the settings needed for each. The deepest or strongest setting is not applied to every area.

Shallow · Middle · Deep — Adjusting the Treatment to Your Skin

XERF’s three Depth settings adjust how thermal energy spreads. Settings can differ by area according to skin thickness, facial volume, sagging, and fine lines.

Settings for thin, delicate skin take those characteristics into account. In areas where loss of firmness is more pronounced, the treatment area is planned according to skin condition. A deeper setting is not better for every skin type or area.

Wave Fit Pulse and ICD Cooling — Adjusting Heat and Energy Delivery Together

Wave Fit Pulse is a technology that varies the pulse according to the energy being delivered. It adjusts energy delivery as heat builds and is maintained.

ICD cooling uses refrigerant gas to control heat at the skin surface. Variable pulses and cooling settings work together to help prevent excessive heat buildup. Heat or pain may still be felt during treatment, so we monitor your skin’s response and comfort throughout.

Monitoring Skin Condition and Surface Temperature

XERF has impedance feedback to assess the skin’s electrical resistance, along with a surface-temperature monitoring function. The clinician considers both the information displayed by the device and the skin’s actual response during treatment.

When Do Effects Begin, and How Long Do They Last?

You may feel skin tightening immediately after treatment. Changes in firmness and facial contours may then gradually appear over the following weeks to months as collagen remodels.

The onset and duration of these changes vary with skin condition, the treatment area and settings, and individual response. We monitor progress rather than judging the result by the initial tightness or swelling alone. If further treatment is needed, its timing is determined by reviewing changes in firmness and the response to previous treatment.

How Is the Procedure Performed?

1. Consultation and Skin Assessment: We examine sagging, fine lines, skin thickness, facial volume, and previous treatment history.

2. Treatment Area Planning: We determine the Depth setting, intensity, and treatment area for each region, and select a tip suited to skin condition.

3. Preparation and Settings Check: The skin and device are prepared, then skin condition and cooling settings are checked. Whether anesthesia is used depends on the treatment plan and pain sensitivity.

4. Radiofrequency Treatment: The tip is placed in close contact with the skin to deliver energy. Treatment generally takes about 15–30 minutes, depending on the area and shot count.

5. Skin Response Check: We check the skin for redness, warmth, and other responses, and explain aftercare.

Recovery and Precautions

• A return to daily activities is often possible after treatment. Redness, swelling, warmth, or tenderness may occur, and recovery varies by individual.
• Maintain moisturizing and sun protection, and avoid strong friction or irritating cosmetics until the skin has settled.
• If warmth or redness remains, take a break from strenuous exercise and excessive heat exposure, such as saunas or jjimjilbang (Korean-style sauna/bathhouse).
• Adjust cleansing and makeup according to your skin’s response. If you receive another procedure at the same visit, follow its precautions as well.
• Please tell us about any important upcoming event. We consider both skin condition and the time needed for recovery.

Please Contact the Clinic If

• Blisters, oozing, or burn marks develop
• Pain, redness, or swelling progressively worsens
• Skin color changes noticeably or altered sensation persists
• You experience unusual discomfort and would like your recovery checked

How WayB Approaches This

• We assess skin thickness, volume, and areas of pronounced sagging separately, rather than applying the same settings across the entire face.
• We distinguish hollow areas from areas needing firmness care to determine the treatment area and energy settings.
• We consider the treatment area, energy and cooling settings, and skin response together, rather than explaining results by shot count alone.
• We check the heat and pain you feel during treatment and adjust the settings and approach accordingly.
• If another lifting or volumizing procedure is better suited to your skin, we explain that option as well.

XERF FAQ

Q. What kind of treatment is XERF?

XERF uses monopolar radiofrequency at two frequencies, 6.78 MHz and 2 MHz, to address skin firmness and facial contours. The range and intensity of energy delivery are adjusted to skin thickness and volume, with variable pulses and cooling used together.

Q. How is XERF different from CoolSoniq?

XERF uses radiofrequency, while CoolSoniq uses high-intensity focused ultrasound (HIFU). Both address skin firmness and sagging, but their energy delivery methods and treatment plans differ. At WayB, we assess skin thickness, facial volume, sagging, and fine lines before recommending a suitable approach.

Q. How is XERF different from Thermage FLX?

Both use monopolar radiofrequency, but their energy delivery and cooling methods, tips, and treatment settings differ. XERF features two frequencies, 6.78 MHz and 2 MHz, three Depth settings, Wave Fit variable pulses, and ICD cooling. We choose the treatment after assessing skin condition and the changes you want.

Q. Is XERF less painful?

XERF is designed to reduce heat and discomfort during treatment through variable pulses and ICD cooling. However, the sensation varies with the treatment area, settings, and individual sensitivity. Please tell us about any discomfort during treatment so we can check your skin’s response and adjust the settings and approach.

Q. Can I receive XERF if I have little facial fat or hollow cheeks?

If you have little facial fat or hollowing, skin thickness and volume distribution must be checked first. We distinguish reduced firmness from volume loss to determine the treatment area and settings. Depending on skin condition, another procedure may be more suitable.

Q. How long does XERF treatment take?

Treatment generally takes about 15–30 minutes, depending on the area and shot count. Consultation, preparation, and any additional procedures take extra time, so we explain the overall visit schedule when you book.

Q. When do effects appear, and how often should I receive treatment?

You may feel tightening immediately after treatment, with gradual changes in firmness over the following weeks to months. The duration of results and the interval needed between treatments vary by individual. We assess skin condition and the response to previous treatment to determine whether and when another session is needed.

Q. Can I return to daily activities right after treatment?

A return to daily activities is often possible, but temporary redness, swelling, or warmth may occur. Adjust cleansing and makeup according to recovery, and maintain moisturizing and sun protection. Please contact the clinic if you develop blisters, worsening pain, or changes in skin color.
