ONDA may reduce localized face fat for many patients. It uses Coolwaves microwave energy designed to heat fat tissue beneath the skin while a cooling system protects the surface, which can slim fullness around the cheeks, jawline and under the chin. At Re:berry Hongdae, results are usually gradual over several weeks and vary by individual.

How does ONDA work on facial fat?
ONDA delivers microwave energy that is selectively absorbed by water-containing tissue, focusing heat in the fat layer below the skin. Integrated cooling protects the surface so the skin stays comfortable. The heat is intended to affect fat cells and also stimulate collagen in surrounding tissue, so many patients notice both slimming and firming. See ONDA Face Lifting for full details.
Who is ONDA suitable for?
- Adults with soft, pinchable fullness in the lower face or under the chin
- People who want contour refinement without needles or surgery
- Those with mild laxity alongside fullness
ONDA is less suitable when width comes from a large chewing muscle, which may respond better to jaw Botox, or from bone structure. It is not a substitute for weight loss. Pregnancy, metal implants in the area and some medical conditions are reasons to avoid or postpone treatment.
How many sessions are needed?
Many plans involve several sessions spaced a few weeks apart, though the number depends on the area and your response. Change is usually gradual and subtle rather than dramatic. Some patients combine ONDA with the Berry Slim contour injection for small stubborn pockets, as explained on our double chin page.
How is ONDA different from ultrasound lifting?
Ultrasound devices such as Ulthera focus on lifting the deeper support layer and building collagen, while ONDA is mainly chosen for localized fullness with some tightening. If your concern is sagging rather than fat, ultrasound lifting may be prioritized, and some patients benefit from both in one plan.
What does it feel like and is there downtime?
Most people feel warmth as the handpiece moves, with cooling for comfort. Afterward, mild redness, warmth or tenderness may last a few hours to a day. Most patients return to normal activities immediately. Pricing depends on area and plan and is confirmed in writing at consultation; see our Location & Hours page for hours.

Related questions
Will ONDA make my face look hollow?
ONDA targets localized fullness, and treatment is planned around your anatomy to keep results natural. People with very little facial fat may not be good candidates, which is why the doctor assesses fat thickness first. Communicate whether you want a subtle refinement or a more noticeable change.
Is ONDA better than a contour injection?
Neither is simply better. ONDA is a device that covers broader areas without needles, while a contour injection such as Berry Slim targets small, defined pockets. Many plans combine both. The doctor will recommend an approach based on where your fullness sits and how much there is.
How long do ONDA results last?
Fat cells affected by treatment are not expected to return in the same way, but remaining fat cells can grow with weight gain, and aging continues. Keeping a stable weight helps preserve results. Some patients choose periodic maintenance sessions, depending on their goals and the doctor's advice.
