InMode vs Onda: Which Treatment Is Better for Skin Tightening and Fat Reduction?

Last week, my team and I attended the 2026 Guangzhou Beauty Expo, where we had the chance to test two of the most talked-about body contouring technologies of the year — InMode and Onda.

At the event, we didn’t just watch demonstrations; we actually experienced both treatments ourselves. Two of our colleagues received the treatments so we could evaluate the real patient experience and results.

If you’re considering adding one of these trending treatments to your clinic or aesthetic practice, this guide will help you better understand the differences between the two technologies.

What Is InMode?

InMode is an advanced aesthetic technology platform that uses radiofrequency (RF) energy to tighten skin, reduce fat, and improve facial contours.

It has become popular worldwide because it offers non-surgical lifting and body contouring with minimal downtime.

How InMode Works

InMode treatments use radiofrequency energy to heat the deeper layers of the skin. This heat stimulates collagen production and breaks down fat cells while tightening the skin.

Some applicators also use vacuum suction combined with RF energy, allowing the device to target deeper tissues effectively.

The heat generated during treatment triggers several beneficial processes:

• Collagen remodeling

• Fat cell breakdown

• Improved blood circulation

• Skin tightening

Over time, the body naturally removes the damaged fat cells, leading to visible slimming and firmer skin.

Popular InMode Treatments

The InMode platform includes several treatment technologies designed for different concerns.

Face Treatments

• Forma – skin tightening and collagen stimulation

• FaceTite – minimally invasive facial contouring

• AccuTite – precision contouring for small areas

Body Treatments

• BodyFX – fat reduction and body contouring

• Morpheus8 – RF microneedling for skin tightening

• EvolveX – muscle toning and fat reduction

Each applicator targets specific concerns such as double chin, sagging skin, or stubborn fat pockets.

Benefits of InMode

InMode has become a popular option because it offers multiple aesthetic benefits in one treatment system.

Key advantages include:

• Non-surgical skin tightening

• Fat reduction in targeted areas

• Improved facial contour

• Increased collagen production

• Minimal downtime

Many patients notice gradual improvements in skin firmness and contour within weeks after treatment.

Areas Treated with InMode

InMode can be used on both the face and body.

Common treatment areas include:

• Jawline

• Double chin

• Cheeks

• Neck

• Abdomen

• Arms

• Thighs

• Love handles

Because of its versatility, InMode is often chosen by patients who want both skin tightening and fat reduction.

What Is Onda?

Onda is another non-invasive body contouring treatment, but it uses a different type of energy called Coolwaves™ microwave technology.

Unlike radiofrequency devices, Onda uses microwaves to target fat cells directly, making it particularly effective for fat reduction and cellulite treatment.

How Onda Works

Onda’s Coolwaves technology delivers controlled microwave energy into the subcutaneous fat layer.

This energy causes fat cells to heat up and break down while also stimulating collagen production in the surrounding tissue.

The process works through:

• Heating fat cells

• Destroying adipose tissue

• Stimulating collagen fibers

• Improving skin elasticity

After treatment, the body gradually eliminates the damaged fat cells through the lymphatic system.

Benefits of Onda

Onda is widely known for being comfortable and effective for body contouring.

Key benefits include:

• Non-invasive fat reduction

• Cellulite improvement

• Skin tightening

• Comfortable treatment sessions

• Minimal recovery time

Many patients choose Onda because it focuses specifically on fat and cellulite reduction with little discomfort.

Areas Treated with Onda

Onda treatments are usually performed on body areas where fat and cellulite tend to accumulate.

Common treatment areas include:

• Abdomen

• Love handles

• Thighs

• Buttocks

• Back fat

• Double chin

Because Onda can target deeper fat layers, it is often used more for body sculpting than facial lifting.
