Hello from Seye Clinic, Gangnam. Onda uses microwave (Coolwaves) energy to protect the skin surface with cooling while delivering heat to the dermis and subcutaneous fat layer.
It's a popular choice when you want to firm laxity and refine contour β jawline, double chin, cheek fat β at the same time. Because energy is set in "joules (lines)," the right amount depends on your face shape and goal. Here's price, results, joule guidance, sessions, longevity and pain in one page.
Onda sets intensity by the cumulative microwave (2.45 GHz) energy delivered. A cooling system protects the surface while heat targets the dermis and subcutaneous fat, stimulating collagen to firm the skin and gently refining excess fat. That's why Onda can address both firmness and contour.

Onda starts from approximately β©450,000~ (VAT separate). Cost varies by the total energy (joules) and area, so please see the tiered guide below.
Plan | For | Price (VAT separate) |
|---|---|---|
Onda Face (starting) | light firming / texture | from approx. β©450,000 |
Onda Face (jawlineΒ·double chin) | jawline & double chin | Ask at consultation |
Onda Face (intensive) | firming + contour | Ask at consultation |
Onda Body | body contour | Ask at consultation |
Prices are as of September 2026 and are confirmed at consultation based on your skin and the joules used.
Onda helps refine the jawline and double chin by acting on cheek/under-chin fat, firms laxity and fine lines through collagen stimulation, and is also used for body areas such as the abdomen and arms. Results build gradually over about 2β4 weeks as collagen forms, and vary between individuals.
Refining jawline/double chin without surgery; both laxity and cheek-fat concerns; wanting lifting with little pain or downtime; busy schedules with little recovery time.

Joules (lines) | Mainly for | Who |
|---|---|---|
40,000β50,000 | light surface firming / texture | thin skin, minimal fat (20sβearly 30s) |
60,000β80,000 | jawline & double chin definition | most common Β· moderate fat + laxity (late 30sβ40s) |
100,000+ | body contouring / significant fat | severe double chin; body areas |
The right amount depends on face shape, fat/laxity and goal β decided after consultation.
A series of about 3 sessions (3β5 depending on skin) at 3β4 week intervals is generally recommended. Spacing sessions lets the collagen response build.
Changes begin gradually from about 2β4 weeks. Smooth contour is generally maintained about 6 months to 1 year, with variation by aging, lifestyle and individual factors. Some patients add periodic maintenance sessions.
Onda is generally low in pain β surface cooling means many patients find it comfortable, feeling deep warmth rather than a sharp sting, often without topical anesthesia. Downtime is minimal, though temporary redness or warmth may occur and varies by individual.
Avoid heavy alcohol, saunas and strong sun on the treatment day. Consultation is required if pregnant, or with certain skin conditions or implanted devices. Combining with other lifting (InMode, Thermage) or skin boosters is decided after consultation.
