What Is Onda?

Onda is a non-invasive aesthetic treatment developed by DEKA that utilizes Coolwaves™ technology, a specialized microwave energy operating at approximately 2.45 GHz. The energy penetrates deep into the subcutaneous fat layer while minimizing heat exposure to the skin surface.

Unlike liposuction, Onda does not require:

• Incisions
• Anesthesia
• Hospitalization
• Compression garments
• Recovery time

The treatment is performed entirely in a clinic setting.

Why Onda Is So Popular in Korea

Korean patients often seek treatments that provide:

• Natural-looking contour improvement
• Minimal downtime
• Skin tightening
• Fat reduction
• Preventive anti-aging benefits

Onda fits these goals because it can simultaneously target stubborn fat deposits and stimulate collagen remodeling.

Many Korean dermatology clinics position Onda as a treatment between traditional lifting devices and body contouring procedures.

How Onda Works

Fat Reduction

Coolwaves™ selectively penetrate into the fat layer and disrupt adipocyte membranes.

The damaged fat cells are gradually processed and eliminated through the body's natural metabolic pathways.

Skin Tightening

The microwave energy also stimulates collagen contraction and new collagen production.

This can improve:

• Skin firmness
• Elasticity
• Mild skin laxity
• Overall skin quality

over several weeks following treatment.

Cellulite Improvement

Onda can affect fibrous connective tissue associated with cellulite, helping smooth the skin's surface and reduce the appearance of "orange peel" texture.

What Areas Can Onda Treat?

Double Chin

One of the most popular applications in Korea.

Onda may help:

• Reduce submental fat
• Improve jawline definition
• Tighten the neck area

without surgery.

• Facial contouring
• Mild jowls
• Early skin laxity
• V-line enhancement

especially among patients seeking non-surgical facial slimming.
