Density vs ONDA vs InMode in Seoul: three newer lifting devices compared

Ultherapy and Thermage are the names most visitors already know. Once you start reading Korean clinic menus, three more appear again and again: Density, ONDA and InMode. This guide sets out how LIV Plastic Surgery describes each of them, what they take in time and recovery, and what they cost, so you can ask better questions before you message a clinic. LIV is a non-surgical anti-aging clinic in Gangnam, one minute from Sinsa Station and next to Garosu-gil. International patients pay from the same price list as Korean patients, and you can book directly in English without an agency.

The short answer

The three do not use the same energy, and the clinic does not describe them for the same person.

• Density is described by the clinic as an entry-level RF (radiofrequency) lifting device at a reasonable cost. It covers the forehead, eye area, cheeks, jawline and neck.
• ONDA is not RF. It uses 2.45 GHz microwave energy, needs no anesthesia, and is the only one of the three the clinic also uses on the body.
• InMode is the option the clinic recommends when facial fat and sagging skin are a combined concern, with FX and FORMA modes priced separately.

This is not a ranking. Which one fits you, or whether a different treatment on the lifting pages fits better, is decided with the doctor at the consultation.

Density, ONDA and InMode at a glance

All values are from LIV's treatment pages and medical Q&A. The clinic's international patients page lists revisit guidance for Ultherapy Prime, Thermage FLX and thread lifts only, so ask about follow-up for these three when you book.

What each device is for

Density

The clinic describes Density for people who want a combined lifting effect, who want both an immediate effect and long-term improvement, and who were not satisfied with an earlier lifting treatment. Treatment takes 40–60 minutes; anesthetic cream is optional. The clinic's results line reads "immediate lifting + collagen regeneration over 3–6 months", and it recommends an interval of 3–6 months between sessions. Asked how it differs from Ultherapy Prime and Thermage, the clinic's answer is that Density is an entry-level RF lifting device at a reasonable cost. See the Density page.

ONDA

ONDA is often assumed to be another RF device. The clinic's own answer is no: it uses 2.45 GHz microwave energy. It is described for people who have loss of elasticity together with localized fat, who want improvement without downtime, and who want to care for the face and body together. On the face it treats the cheeks and jawline and the double chin in 15–30 minutes; on the body it treats the abdomen, flanks, thighs and arms at about 10 minutes per area. It is performed without anesthesia and is reported to feel similar to a warm massage. Results are not immediate: they appear gradually over 4–12 weeks and vary by individual. See the ONDA page.

InMode

The clinic recommends InMode for people whose concerns combine facial fat and sagging skin. Its listed uses are reducing fat under the chin while strengthening elasticity, lifting the cheeks and tidying the face line, improving a double chin and the deep cheek area, and collagen regeneration with improvement of fine lines. Treatment takes 30–60 minutes, with no anesthesia or with anesthetic cream. The clinic lists it alongside Shurink as a maintenance treatment that can be done every 3–6 months. It can also be combined with Thermage: the clinic says RF synergy allows a stronger improvement in elasticity. See the InMode page.

Prices at LIV (2026, per session)

Density and InMode prices are published on their treatment pages.

The tilde means "from". Which Density tip and shot count, or which InMode mode, applies to you is agreed with the doctor at the consultation, and that is when the final figure is set. For Ultherapy Prime, Thermage FLX and Shurink prices, see the price list and our Ultherapy vs Thermage vs Shurink guide.

Who each one suits, in the clinic's words

Treat the table as a map of how the clinic describes each device, not as a diagnosis. Two people with the same concern can be given different plans, and the doctor may suggest a treatment that is not in this comparison at all, such as Ultherapy Prime, Thermage FLX or a thread lift.

What to tell the doctor

These cautions are the clinic's own. Mention anything that applies in your first message.

• Pregnancy and breastfeeding. Density and InMode are not performed during pregnancy or while breastfeeding. For ONDA, the clinic asks you to tell it at the consultation if you are pregnant or breastfeeding.
• Pacemaker or metal implants. For ONDA, tell the clinic if you have a pacemaker or a metal implant in the body.
• Skin problems in the treatment area. For ONDA, tell the clinic about any inflammation, infection or wound in the area. For Density and InMode, whether treatment is possible depends on your skin condition and is checked at the consultation.
• Underlying conditions. For ONDA, tell the clinic about conditions such as uncontrolled diabetes.
• After the treatment. Mild swelling or redness is possible after Density and InMode.

Fitting it into a Seoul trip

• Same-day treatment. Most non-surgical treatments at LIV take 30 to 90 minutes and need no hospitalization, so many patients are treated on the day of their visit.
• Booking. Message the clinic on WhatsApp (+82 10-6888-2773), the live chat or the contact form. Share your concerns and photos, and the clinic suggests suitable treatments and sends a price estimate before you travel. Replies come within one business day, and no deposit is needed to reserve a consultation. The steps are in our booking guide.
• Language. Consultations are available in English; interpretation is arranged free of charge on request.
• Clinic hours. Monday to Friday 10:00–19:00, Saturday 10:00–16:00, closed Sunday (Korea time).
• Getting there. Sinsa Station (Line 3), Exit 4, a 1-minute walk. See location.
• Timing your flight. All three list an immediate return to daily life. Your own timing is confirmed at the consultation; our downtime and flight guide covers planning.

Before you decide

This comparison shows how the three devices differ, not which one your skin needs. That is decided at the consultation, where the board-certified plastic surgeon diagnoses your skin in person and recommends a plan; see our medical team. The 1:1 consultation fee is KRW 10,000, fully deducted from the treatment cost if you go ahead the same day, and you are free to decide later. Send questions through the international patients page or the contact form; more answers are on the medical Q&A page.

This guide is general information, not medical advice or a diagnosis. Suitability and the final plan are decided at your in-person consultation. Prices are per session, exclude VAT, and are confirmed after consultation.
