Results Over Time
ONDA (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.
1Immediately post
Mild warmth and transient redness; resolves within hours.
21–2 weeks
Early changes may begin as swelling settles and the treated-tissue response starts.
34–8 weeks
Submental fat reduction and collagen remodeling may become more noticeable.
48–12 weeks
Visible contouring and continued tightening; peak ~3 months post-final session.
5Post-course
Maintenance may be planned based on submental fat, jawline contouring goals, and individual response.
ONDA Device & Tips
ONDA's Deep and Superficial handpieces deliver Coolwaves™ microwave energy: fat-cell breakdown in the subcutaneous layer, collagen contraction and tightening in the dermis.
Dual Handpieces
Deep (7 mm) targets the subcutaneous fat layer for localized fat reduction; Superficial (3 mm) acts on the dermis to contract collagen and improve elasticity.
Comfort and Sensation
Built-in cooling supports comfort, but warmth, tingling, or discomfort can occur. Sensitivity varies by person and treatment area.
Gradual Changes
Changes may develop over the weeks after treatment. The degree and timing of improvement vary, and visible results are not guaranteed.
Treatment Process
1Consultation & Assessment
The dermatologist assesses the facial structure or body area and selects the appropriate ONDA handpiece.
2Coolwaves Delivery
Coolwaves microwave energy is delivered through the selected applicator.
3Face Treatment
Targets the dermis for collagen stimulation and skin tightening.
4Body Treatment
Targets subcutaneous fat for localized fat reduction.

- 9. Warmed subcutaneous fat, enlarged
In the film
- On the abdomen, a body handpiece that delivers energy to the subcutaneous fat is used.
- The handpiece rests upright against the skin and moves continuously in figure-of-eight passes.
- The skin surface is cooled while microwaves heat the subcutaneous fat.
Treatment Results
Clinical photographs. Individual results vary with skin condition, age, and treatment plan.
Recovery & Care
First 24 hours
Avoid hot showers, saunas, sun, and vigorous exercise.
Days 1–7
Treated body areas may feel sore, like post-exercise. Cool compress if tender; stay hydrated.
Weeks 1–4
Resume full activity. Use sun protection on any treated facial area.
Session interval (2–4 weeks)
Return for the next session; the dermatologist adjusts handpiece and energy.
Frequently Asked Questions
Q.How much does ONDA Coolwaves cost in Korea?
Delight Dermatology in Gangnam, Seoul publishes these prices in Korean won: ONDA Microwave (Body), KRW 750,000–2,600,000 per session (energy level varies by area). The itemized quote follows the examination and depends on the treatment area, amount and plan.
Q.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.
Q.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.
Q.Can ONDA be combined with other procedures?
Yes. Combining ONDA with Ultherapy can enhance lifting synergy, and combining it with Thermage can improve overall lifting and skin firmness.
Q.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.
