What ONDA Does
ONDA uses 2.45 GHz microwave energy to deliver energy selectively to subcutaneous fat and connective tissue. Energy is designed individually, within about 40 to 100 kJ for the face and 100 to 300 kJ for the body. The doctor selects and combines the 3 mm and 7 mm handpieces according to the treatment area, skin thickness, laxity, fat distribution and treatment goal.
How Your First Visit Unfolds
The doctor then provides a detailed consultation on the treatment areas and method, completes the medical assessment and performs the treatment directly. A treatment takes about 15 minutes for a facial area and about 30 minutes for a body area. Anesthetic cream is generally not required for ONDA.
Downtime and Safety
If there are no particular issues, makeup and flying are possible on the same day. After a single session, the next session may be considered after about four to six months. An intensive course of three sessions may be performed about three to four weeks apart, followed by maintenance about once a year. Recovery and visible change vary by person.
Common reactions
- Common temporary reactions may include redness and swelling.
Serious side effects
- Less common but important adverse effects may include lumps under the skin, blisters, volume loss and asymmetry.
Common Situations and Concerns
You may hesitate because you worry about comfort and downtime. Comfort varies by person, and expectations are discussed during the consultation. If you have an important event or photo shoot coming up, a few days of extra time can help you feel at ease. Results are gradual and vary by person, and a long-term treatment plan can be considered.
