ONDA Coolwaves in Seoul | DEKA Italy 2.45 GHz Microwave Contouring

ONDA (manufactured by DEKA Italy) uses proprietary Coolwaves™ — a 2.45 GHz microwave technology that selectively targets adipocytes and fibrous septa in the subcutaneous layer while keeping the skin surface cool. Unlike conventional RF or HIFU body devices, Coolwaves penetrates with high selectivity to fat tissue, enabling precise fat reduction, cellulite improvement, and skin tightening in a single session.

Aftercare

01First 24 hours
Mild redness and warmth in treated area. Avoid hot showers, saunas, intense sun exposure, and vigorous exercise.
02Days 1-7
Body treatments may cause soreness similar to post-exercise. Apply cool compress if tender. Stay hydrated to support lymphatic clearance of fat metabolites.
03Weeks 1-4
Resume full activity. Continue sun protection on any treated facial area as newly stimulated collagen is photodamage-sensitive.
04Session interval (2-4 weeks)
Return for the next session in the planned course. The dermatologist may adjust handpiece selection and energy based on interim response.

FAQ

Is ONDA the same as Thermage or Ultherapy?

No. ONDA uses microwave energy (Coolwaves), which is a different mechanism from Thermage (radiofrequency) and Ultherapy (ultrasound). Each targets tissue differently.

Can ONDA be used for both face and body?

Yes. ONDA uses three handpiece tips — Smart (face tightening), Deep (subcutaneous fat reduction), and Shallow (surface skin quality) — covering two clinical categories: facial skin tightening and fat reduction on face or body. The dermatologist selects the appropriate handpiece combination based on your treatment goal.

Can ONDA be combined with other procedures?

Yes. Combining ONDA with Ultherapy can enhance lifting synergy, and combining with Thermage can improve overall lifting and skin firmness.

How many sessions are needed?

For facial lifting, 1-3 sessions are typically recommended. For body contouring, three sessions spaced 4 weeks apart provide the most effective protocol; results are generally maintained for about 6 months after a 3-session course.
