If you’ve just completed ONDA and you’re weighing a second round, the short answer is: risks and downtime vary by the treatment area, the energy planned in kilojoules (kJ), and the handpiece depth used. At Min Clinic in Gangnam, Cheongdam, the doctor plans these factors per patient and reviews what you personally should expect and watch for after treatment. Bring your previous ONDA records so your plan can be adjusted with your history in mind.

What ONDA is and where it acts

ONDA (ONDA / ONDA Plus) is an energy-based treatment made by DEKA M.E.L.A. S.r.l. (Calenzano, Italy). It uses Coolwaves, a patented 2.45GHz microwave technology the manufacturer describes as disrupting the membranes of subcutaneous fat cells while also stimulating collagen production. Two handpieces target different depths: a deeper option is used for localized fat on areas such as the abdomen, flanks, knees, buttocks and underarms, and a shallower option is used for cellulite, skin firmness and the submental area.

The manufacturer lists three applications: localized fat, cellulite and skin laxity. Regulatory labeling and permitted uses can differ by market; at Min Clinic, ONDA is used according to the manufacturer’s listed applications.

Risks, downtime and what to discuss after a repeat session

Because you have prior ONDA experience, your post-treatment course is best planned against your earlier response: How your skin felt, how quickly sensitivity settled, and when you saw changes. At Min Clinic, the amount of energy is measured in kilojoules (kJ) and the handpiece (3mm or 7mm) is chosen to match your skin thickness, fat distribution and goal for each area. The doctor reviews these details so that you understand what to expect after this session.

Instead of a generic timeline, use this checklist during your review:

Which handpiece depth will be used for each area, and why that choice fits my skin thickness and fat distribution.
The planned total energy in kJ for each area and whether it differs from my prior session.
What sensations are expected during and after, how long they typically last in cases like mine and what signs would merit a call-back.
When I can return to my usual routine, exercise and travel, given the area and energy planned.
Which skincare or body-care steps the clinic recommends after ONDA and for how long.
The planned number of sessions and spacing based on my response so far.

The number and frequency of ONDA treatments at Min Clinic are tailored to the degree of skin laxity and lower-face fat or to the characteristics of the body area. After a single treatment, a follow-up may be recommended after about four to six months. When a course of three treatments is performed at approximately three- to four-week intervals, a maintenance treatment may be recommended after about one year. The specific plan can vary by condition and response. A facial session typically takes about the length of a short appointment and a body area about the length of a standard appointment slot; actual session times can vary by area and energy plan.

What to check in Gangnam, Cheongdam before you book again

When comparing ONDA options in this neighborhood, align like with like so you understand what you’re choosing:

Device authenticity and model: Confirm the clinic uses an authentic ONDA device (ONDA / ONDA Plus).
Treatment area: Define exactly which areas will be treated.
Planned energy in kJ: Ask for the planned total kJ by area. This is the unit Min Clinic uses to plan and record energy delivery.
Handpiece plan: Confirm which handpiece depth will be used where, and why.
Who performs the treatment: Ask who will actually perform ONDA and how the session is supervised.
Aftercare: Clarify what aftercare is included and whom to contact with questions.
Device generation and protocol differences: If mentioned, ask what they mean in practice for your skin; if details are not available, confirm with the clinic.

Prices are determined by factors such as the treated area and total energy. All listed prices exclude VAT. Anesthetic cream is not required. For exact inclusions and ONDA pricing, confirm with the clinic

Planning your second ONDA at Min Clinic

Personalized mapping: The doctor assesses skin laxity, fat distribution and the target areas before selecting the 3mm or 7mm handpiece and setting energy in kJ. A higher energy or a particular handpiece is not automatically better; the plan follows your anatomy and goal.
Session scheduling: A single follow-up may be timed after about four to six months, or a series may be spaced by about three to four weeks, with maintenance later. Your prior response helps determine which path suits you.
Companions to consider or avoid: ONDA may be performed alone or as part of a personalized plan. Depending on your laxity, fat distribution and goals, a doctor may discuss Ultherapy PRIME, 10THERMA or QuickSlim injections. These are different modalities and are not automatically combined. The doctor will advise whether to keep ONDA on its own or combine it for your case.
Pregnancy: Min Clinic does not perform medical aesthetic procedures during pregnancy. Selected skincare may be available after consultation.

If you need to verify who performs ONDA, what aftercare steps are provided, or whether certain add-on treatments are advisable in your case, ask the clinic before you schedule.
