At Min Clinic in Nonhyeon-dong, a doctor evaluates the patient and performs ONDA using an authentic DEKA ONDA system. The treatment area, the combination of 3 mm and 7 mm handpieces and the distribution of energy in kilojoules (kJ) are individually designed according to skin thickness, skin laxity, fat distribution and treatment goals. The device authenticity certificate is displayed at the clinic.
How to Evaluate ONDA Treatment in Gangnam and Cheongdam
Confirm the exact device
Ask the clinic to identify the exact ONDA system used for treatment. Min Clinic uses an authentic DEKA ONDA device, and its device authenticity certificate is displayed at the clinic.
ONDA is an energy-based device treatment. It does not involve a vial or a single-use treatment tip that needs to be opened before each session. Authentication methods differ among treatments, so product stickers, holograms and shot-count checks used for other procedures should not be presented as ONDA authentication methods.
Compare the treatment design, not only the device name
Using the same device does not mean every patient receives the same treatment. A meaningful ONDA plan should identify:
* The facial or body area being treated * The planned energy level in kJ * The selection or combination of 3 mm and 7 mm handpieces * How the energy will be distributed across the treatment area * Who will perform the procedure * What is included in the quoted price
Higher energy or using a particular handpiece is not automatically better. The doctor should determine the plan according to the patient’s anatomy, skin condition, fat distribution and goals.
Compare quotes under the same conditions
ONDA pricing at Min Clinic is based on the planned energy level in kJ. Two quotes are only directly comparable when the treatment area, energy level, device, operator and included services are similar.
A lower price may reflect a smaller treatment area or a lower planned energy level. Compare the clinical plan first and the final price afterward.
Confirm who performs the procedure
At Min Clinic, ONDA and other medical aesthetic procedures are performed by a doctor. Skincare treatments are provided separately.
The doctor assesses the patient, determines the treatment range, selects or combines the handpieces and adjusts the energy distribution. This should not be expanded into a claim that every service at the clinic is performed by a doctor.
What ONDA Is and What It Targets
ONDA is a nonsurgical, energy-based treatment that uses DEKA’s 2.45 GHz Coolwaves microwave technology. It is designed for concerns such as localized fat, cellulite and skin laxity.
The system includes 3 mm and 7 mm handpieces. These are not assigned to fixed body parts solely according to depth. The doctor may select one handpiece or combine both after considering:
* Skin thickness * Degree of skin laxity * Amount and distribution of localized fat * Facial or body treatment area * Individual treatment goals
At Min Clinic, the handpiece combination and energy allocation are planned individually rather than applied through a fixed protocol.
Patients may notice an initial feeling of tightness after treatment. Changes may become more noticeable over approximately two to four weeks, with the contour continuing to develop gradually over the following two to three months. The timing and degree of change vary among individuals.
ONDA Planning for Male Patients
Min Clinic does not apply a separate ONDA treatment standard based on sex.
For male patients, as with all patients, the doctor evaluates skin thickness, skin laxity, fat distribution, facial structure or body build and the specific area of concern. Treatment is then designed according to the individual patient rather than generalized assumptions about male skin, facial hair or oil production.
Facial concerns
For the lower face, jawline or under-chin area, the doctor evaluates the degree of skin laxity and localized fat before deciding:
* Whether ONDA is suitable * Which areas should be included * Whether the 3 mm or 7 mm handpiece, or a combination of both, is appropriate * How much energy should be applied * How the energy should be distributed across the area
Facial hair or shaving routines may be discussed if they affect skin irritation on the treatment day, but they do not create a separate male ONDA protocol.
Body concerns
For areas such as the upper arms, abdomen, thighs or bra-line area, treatment range and energy are adjusted according to the size of the area, fat distribution, skin condition and body build.
Examples of energy ranges used as planning references at Min Clinic include:
* Upper arms: approximately 100–200 kJ * Partial abdomen: approximately 100–200 kJ * Thighs: approximately 200 kJ * Bra-line area: approximately 100–200 kJ
These figures are general references rather than guaranteed prescriptions. The doctor determines the actual energy and treatment range after examining the patient.
Combining ONDA with other treatments
ONDA may be considered on its own or as part of an individualized plan. Depending on the concern, the doctor may also consider treatments such as:
* Ultherapy PRIME * 10Therma * QuickSlim injections, a fat-dissolving injection treatment
These treatments use different mechanisms and are not automatically combined. The appropriate treatment or combination depends on whether the main concern is skin laxity, localized fat, facial structure or overall contour.
What Happens at Min Clinic
Consultation process
A senior consultation manager conducts the initial consultation. When appropriate for a facial treatment, an EVE V MUSE skin analysis may also be performed.
The doctor then evaluates the patient’s skin laxity, skin thickness, fat distribution and treatment area. Based on this assessment, the doctor designs:
* The treatment range * The selection or combination of 3 mm and 7 mm handpieces * The total energy level in kJ * The distribution of energy across the treatment area
The skin-analysis results do not automatically determine the treatment plan. The final medical assessment and ONDA design are completed by the doctor.
Patients may attend a consultation without committing to treatment. Same-day treatment may be available depending on the clinic’s schedule and the doctor’s assessment.
English interpretation is available by appointment. Chinese and Japanese assistance is also available.
Doctor-performed treatment
A doctor performs the ONDA procedure at Min Clinic. The doctor follows the individually designed plan and may adjust the treatment according to the area and the patient’s response during the procedure.
ONDA uses an integrated cooling system and a moving application technique. Many patients describe the procedure as having a relatively low pain burden, although heat, pressure or discomfort can vary depending on the treated area, energy level and individual sensitivity.
Topical anesthetic cream should not be described as a standard inclusion for ONDA.
Device authenticity
Min Clinic uses an authentic DEKA ONDA system, and the device authenticity certificate is displayed at the clinic.
Because ONDA is a reusable energy-based system, there is no vial or single-use ONDA tip that needs to be opened in front of the patient. The device certificate is the relevant method of confirming authenticity at the clinic.
How ONDA Pricing Works
At Min Clinic, ONDA pricing is based on the planned energy level in kilojoules.
The general energy ranges are:
* Face: 40–100 kJ * Body: 100–300 kJ
Facial options may include 40, 60, 80 or 100 kJ. Body options may include 100, 200 or 300 kJ.
These energy levels are not interchangeable with the number of shots used for other devices. The doctor determines the appropriate amount and distribution of energy according to the treatment area, skin laxity, localized fat and individual goals.
VAT is charged separately at the applicable statutory rate. International and Korean patients are charged according to the same clinic pricing policy.
When comparing ONDA quotes, ask each clinic to specify:
* The exact device * The facial or body treatment area * The total planned energy in kJ * The handpiece selection or combination * Whether the procedure is performed by a doctor * What aftercare is included * Whether VAT is included or charged separately
Recommended Sessions and Treatment Intervals
The recommended number of ONDA treatments depends on the degree of skin laxity, the amount of localized fat, the treatment area and the patient’s response.
After one treatment, another session may be recommended after approximately four to six months.
For a more intensive treatment course, three sessions may be performed at intervals of approximately three to four weeks. After completing three sessions, maintenance may be considered after approximately one year.
These are general clinic guidelines rather than fixed schedules. The doctor determines the appropriate interval after assessing the patient’s condition and treatment response.
Treatment time also varies according to the area, energy level and individual plan. As a general reference, a facial treatment may take approximately 15 minutes and a body treatment approximately 30 minutes. Actual treatment time may be shorter or longer.
Recovery and Daily Activities
ONDA generally has limited visible downtime, but individual reactions vary.
Temporary redness may occur and generally improves within approximately four to five hours. Swelling is uncommon, but treatment involving a broader area or more extensive use of the 7 mm handpiece may be followed by swelling lasting approximately two to three days.
Patients may generally wash their face, apply makeup and continue light daily activities on the same day if there are no unusual symptoms. Same-day air travel may also be possible.
Follow the doctor’s instructions if heat, redness, swelling, pain or another unexpected symptom develops. Follow-up guidance is provided according to the patient’s condition and the doctor’s assessment.
