At Min Clinic, a doctor plans and performs ONDA using an authentic ONDA device by DEKA. The doctor selects and combines the 3 mm and 7 mm handpieces according to the treatment area, skin thickness, laxity, fat distribution and treatment goal.
What ONDA Does and Whether It Is Appropriate in Your 20s
ONDA is a nonsurgical, energy-based treatment developed by DEKA. It uses 2.45 GHz Coolwaves microwave technology and is designed for concerns involving localized fat, cellulite and skin laxity.
Being in your 20s does not automatically mean that you need or do not need ONDA. The more relevant questions are:
* Is the main concern skin laxity, localized fat or both? * Which facial or body area needs treatment? * How thick is the skin in the treatment area? * How is the fat distributed? * Would another treatment or waiting be more appropriate?
A consultation may conclude that ONDA is not currently necessary. This is a valid medical recommendation rather than a wasted visit.
The 3 mm and 7 mm Handpieces
ONDA has 3 mm and 7 mm handpieces, but Min Clinic does not assign a particular handpiece to a fixed body part based only on depth.
The doctor selects one handpiece or combines both according to:
* The treatment area * Skin thickness * Degree of skin laxity * Amount and distribution of localized fat * Facial or body anatomy * Individual treatment goals
A higher energy level or a particular handpiece is not automatically better. What matters is how the handpieces and total energy are distributed across the treatment area.
The treatment plan should therefore explain not only how many kJ will be used, but also how the doctor will apply that energy to the areas of concern.
How to Compare ONDA Clinics in Cheongdam
Confirm the exact device
Min Clinic uses an authentic ONDA device by DEKA. It should not be described as ONDA Plus.
When comparing clinics, ask which exact system is used and whether its authenticity can be verified.
Check the authentication method
Min Clinic uses an authentic ONDA device by DEKA, and the device authenticity certificate is displayed in the clinic.
Because ONDA is an energy-based device treatment, there is no individual product or single-use treatment tip to open before each session.
ONDA authenticity should not be described using:
* Product-vial opening * Single-use tip opening * A hologram or authenticity sticker * A live shot count on the device screen
These verification methods may apply to other products or devices but are not the ONDA authentication method used at Min Clinic.
Ask 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 evaluates the patient, designs the treatment range, selects or combines the handpieces and determines how the energy will be distributed.
Compare the same energy and treatment area
Two ONDA quotes are only directly comparable when the following conditions are similar:
* The exact treatment area * The total planned energy in kJ * The device used * The handpiece plan * The person performing the procedure * The services included in the quote
A lower quote may reflect a smaller treatment area or lower total energy. Compare the treatment plan first and the final price afterward.
How Min Clinic Plans ONDA
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 assesses the patient’s skin laxity, skin thickness, localized fat, treatment area and goals. Based on this assessment, the doctor determines:
* The facial or body treatment range * Whether to use the 3 mm handpiece, 7 mm handpiece or both * The total energy in kJ * How the energy should be distributed across the area
The skin analyzer does not automatically determine the ONDA plan. The final medical assessment and treatment 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.
ONDA Energy and Pricing
At Min Clinic, ONDA pricing is based on the total planned energy in kilojoules.
The general treatment ranges are:
* Face: 40–100 kJ * Body: 100–300 kJ
Facial plans may be offered at 40, 60, 80 or 100 kJ. Body plans may be offered at 100, 200 or 300 kJ.
The final energy level is selected according to the treatment area, skin laxity, localized fat and individual goals. The same total energy may also be distributed differently depending on the patient’s anatomy.
VAT is charged separately at the applicable statutory rate.
When requesting a quote, ask the clinic to specify:
* Whether the plan is for the face or body * The exact treatment area * The total energy in kJ * The planned handpiece selection or combination * Who performs the procedure * What is included in the price * Whether VAT is charged separately
Recommended Sessions and Intervals
The recommended number of ONDA treatments varies according to the degree of skin laxity, amount of localized fat, treatment area and individual response.
After one treatment, another treatment may be considered after approximately four to six months.
For intensive care, three treatments 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 guidelines rather than fixed schedules. The doctor determines the appropriate number of treatments and intervals after assessing the patient.
When Changes May Become Noticeable
Some patients may notice an initial feeling of tightness shortly after treatment.
Changes may become more noticeable over approximately two to four weeks. The contour may continue to develop gradually over the following two to three months.
The timing and degree of change vary among individuals. ONDA should not be described as guaranteeing a particular degree of lifting, fat reduction or contour change.
Recovery and Daily Activities
ONDA generally has limited visible downtime, but individual reactions vary.
Redness
Temporary redness may last approximately four to five hours.
Swelling
Swelling is uncommon. However, it may occur when the 7 mm handpiece is used more extensively for localized fat and generally improves within approximately two to three days.
Makeup
Makeup may generally be applied on the same day if there are no unusual symptoms or skin irritation.
Flying
Same-day air travel may be possible if there are no unusual symptoms.
Contact the clinic if redness, swelling, pain, heat or another symptom is severe, continues to worsen or lasts longer than expected.
Considering Other Treatments
ONDA may be considered on its own or as part of an individualized plan.
Depending on whether the main concern is skin laxity, localized fat or facial structure, the doctor may also discuss:
* Ultherapy PRIME * 10Therma * QuickSlim fat-dissolving injections
These treatments use different mechanisms and are not automatically combined. The doctor determines whether ONDA should be performed alone or alongside another treatment after evaluating the patient’s anatomy, skin condition and goals.
Treatments that Min Clinic does not provide should not be included as clinic options.
Authenticity and Medical Team
Min Clinic uses an authentic ONDA device by DEKA. The ONDA device authenticity certificate is displayed in the clinic.
Three doctors practice at Min Clinic:
* Young Soo Min, chief medical director * Min Ji Kim, medical director * Chan Ho Jung, medical director
Two of the three doctors are board-certified specialists.
ONDA is performed by a doctor at Min Clinic. Manufacturer-issued titles and professional credentials should be quoted only as they appear on the corresponding plaques or supporting documents and should not be presented as guarantees of a particular treatment outcome.
