If you’ve been researching cellulite reduction or non‑surgical body contouring, you may have come across Coolwaves (also known as ONDA). It’s a highly searched treatment — and understandably so. But is it the only way to achieve visible fat reduction, smoother skin and improved firmness?

At Aspects of Beauty, we don’t offer Coolwaves or ONDA. Instead, we use a combination of fat cavitation, vacuum suction and radiofrequency (RF) skin tightening — a proven, results‑driven approach that can achieve similar outcomes when tailored correctly.

This guide breaks down how Coolwaves compares to cavitation + RF, and which option may be right for your body goals.

What Is Coolwaves / ONDA?

Coolwaves (marketed as ONDA) uses microwave energy to heat fat cells beneath the skin while protecting the surface layers. The energy targets:

• Localised fat deposits

• Fibrous tissue linked to cellulite

• Skin laxity through collagen stimulation

It’s often promoted as an all‑in‑one solution for fat reduction, cellulite and skin tightening, typically over a series of treatments.

What Is Fat Cavitation, Suction & RF Skin Tightening?

Rather than relying on a single energy source, this approach uses multiple complementary technologies, each working at different layers of the tissue.

Ultrasonic Fat Cavitation

Fat cavitation uses ultrasound waves to disrupt fat cells in targeted areas such as the abdomen, thighs, hips or arms. Once broken down, fat is processed naturally through the body’s lymphatic system.

Vacuum Suction (Lymphatic Stimulation)

Vacuum technology helps:

• Improve circulation

• Assist lymphatic drainage

• Reduce fluid retention

• Smooth the appearance of cellulite

This step is especially important for supporting fat clearance after cavitation.

Radiofrequency (RF) Skin Tightening

RF delivers controlled heat into the dermal layers of the skin to:

• Stimulate collagen and elastin

• Improve skin firmness

• Reduce crepey or loose skin

• Enhance overall texture

When combined, these technologies address fat reduction, skin tightening and cellulite in a layered, customisable way.

Coolwaves vs Cavitation + RF: Key Differences

Feature	Coolwaves / ONDA	Cavitation + Suction + RF
Technology	Microwave energy	Ultrasound + RF + vacuum
Fat reduction	Yes	Yes
Cellulite improvement	Yes	Yes
Skin tightening	Yes	Yes
Customisation	Limited to device settings	Highly customisable per area
Treatment approach	Single device	Multi‑step targeted approach
Sessions required	Often fewer	Typically a treatment series

Can Cavitation & RF Achieve Similar Results to Coolwaves?

In many cases — yes.

While Coolwaves delivers multiple benefits through one technology, cavitation and RF achieve results by targeting each concern individually:

• Cavitation focuses on fat cells• RF targets skin laxity and collagen• Suction supports circulation and smoothing

This layered approach allows treatments to be **adjusted based on:

• Fat thickness

• Degree of skin laxity

• Presence of cellulite

• Treatment area

• Client comfort and goals

For many clients, this customisation is a major advantage.

Which Treatment Is Right for You?

Coolwaves / ONDA May Suit You If:

• You prefer a single‑device approach

• You have deeper, more fibrous fat

• You’re seeking fewer sessions

Cavitation + RF May Suit You If:

• You want a more personalised treatment plan• You have mild to moderate fat and skin laxity

• Cellulite and skin texture are key concerns• You want a cost‑effective, flexible option

Why Consultation Matters

No two bodies respond the same way — and no single technology is "best" for everyone.

At Aspects of Beauty, we assess:

• Fat distribution

• Skin quality

• Cellulite severity

• Lifestyle factors

From there, we design a targeted treatment plan using cavitation, RF and supportive therapies to deliver safe, realistic and progressive results.
