ONDA in Your 30s from a Nearby Hotel: What to Check at a Cheongdam Clinic

Min Clinic uses an authentic ONDA device by DEKA. ONDA plans are designed according to the patient’s anatomy, skin laxity, fat distribution, treatment area and goals rather than using the same energy setting for every patient. The doctor selects the 3 mm and 7 mm handpieces, distributes the energy across the planned area and performs the treatment.

What to check before you book ONDA

* **Confirm the device:** Ask whether the clinic uses an authentic ONDA device by DEKA. Min Clinic uses an authentic ONDA device, and the device authenticity certificate is displayed in the clinic. * **Understand the authentication method:** ONDA is an energy-based device treatment rather than an injectable product. There is no individual vial, syringe or single-use treatment tip to open before each session. * **Compare equivalent quotes:** ONDA pricing is based on the total energy delivered in kJ. Compare the treatment area, planned energy level, device generation, treatment provider, included services and VAT under the same conditions. * **Ask who performs the treatment:** At Min Clinic, ONDA is planned and performed by a doctor. * **Confirm the treatment design:** The 3 mm and 7 mm handpieces should be selected according to the treatment area, skin thickness, laxity and fat distribution. One handpiece or a higher energy level is not automatically better for every patient. * **Check scheduling:** Same-day treatment may be available depending on the clinic schedule and the doctor’s assessment.

How ONDA works

ONDA uses DEKA’s Coolwaves technology, which delivers microwave energy at 2.45 GHz. According to the manufacturer, it is designed for concerns involving localized fat, cellulite and skin laxity.

At Min Clinic, the doctor evaluates the treatment area, skin laxity, skin thickness and fat distribution before selecting the handpiece combination and energy plan.

The 3 mm and 7 mm handpieces reach different tissue depths. They may be used separately or combined depending on the patient’s anatomy and goal. The handpiece is not selected according to the treatment area alone, and the doctor may distribute energy differently across areas within the same treatment zone.

ONDA treatment areas and energy planning

At Min Clinic, facial ONDA treatments are planned from 40 kJ to 100 kJ, while body treatments are planned from 100 kJ to 300 kJ. The final energy level and treatment range are determined after consultation.

ONDA may be used for facial concerns such as the lower face, jawline or submental area and for body-contouring concerns involving areas such as the upper arms, abdomen or thighs. The plan varies according to the size of the area, the amount and distribution of localized fat, skin laxity and the intended goal.

Pricing is based on the total energy delivered in kJ. VAT is charged separately at the applicable statutory rate. Confirm the planned area, energy level and included services when comparing quotations.

Recommended treatment interval

The recommended number of sessions and interval depend on skin laxity, localized fat and the patient’s goal.

After one treatment, another session may be considered after approximately four to six months. When an intensive three-session plan is appropriate, treatments may be performed at intervals of approximately three to four weeks. After completing that plan, maintenance may be considered after approximately one year.

These intervals are general guidance. The doctor determines whether another session is appropriate after reviewing the patient’s condition and response.

Downtime and returning to your schedule

Temporary redness may remain for approximately four to five hours. Swelling is uncommon, but when the 7 mm handpiece is used extensively for fat reduction, temporary swelling may occur and generally improves within two to three days.

Makeup and air travel are generally possible on the same day if there are no unusual symptoms. Recovery varies between individuals, so follow the doctor’s instructions if redness, swelling, heat or discomfort continues.

A facial ONDA treatment may take approximately 15 minutes, while a body treatment may take approximately 30 minutes. Actual treatment time varies depending on the area and planned energy level. Allow additional time for consultation, skin analysis, preparation and post-treatment guidance.

Consultation and treatment planning at Min Clinic

A senior consultation manager conducts the initial consultation, and the patient’s skin is analyzed using an EVE V MUSE analyzer. This is followed by a consultation and assessment with the doctor.

The doctor determines:

* Whether ONDA is appropriate * The treatment area and range * The use and combination of the 3 mm and 7 mm handpieces * The distribution of energy across the area * The total energy level in kJ * Whether ONDA should be performed alone or as part of a broader treatment plan

A consultation generally takes approximately 15 to 30 minutes and may take longer when interpretation or a detailed explanation of the skin analysis is needed. Patients may consult without receiving treatment on the same day. Same-day treatment may be available depending on the schedule and the doctor’s assessment.
