ONDA Coolwaves – Revolutionary body sculpting and cellulite reduction treatment

Onda: the new technology for treating slackening skin and cellulite at Lazeo

Slimming and firming techniques are highly sought-after today.
Regardless of whether you’re thin or plump, athletic or not, cellulite and slackening skin affect all genders and body types. Some people can’t correct these problems even with exercise and healthy eating habits.

At Lazeo, we offer treatment with Onda, a noninvasive body contouring system based on microwaves. It targets localized fat, cellulite, and slackening skin. Read on to find out more.

What is it?

The Onda machine uses Coolwaves microwave technology. It exerts a regenerating and toning action that remains effective over time. Onda melts away localized adiposities on all areas of the body, including the abdomen, thighs, sides, and below the chin.

The treatment can be used to complement other solutions such as cryolipolysis or EMsculpt

and is suitable for all skin colors.

How does it work?

The Onda machine penetrates deep down to destroy adipose cells and dissolve localized fat deposits. After the session, these cells “sweat out” their contents, which then drain away through the lymph system over the course of 2 to 3 months.

It also stimulates skin collagen and conjunctive tissue, which surrounds the adipose cells, to combat the appearance of “orange peel skin” and leave skin firmer and toned.

Onda is designed to focus energy only in the defined areas, while preserving adjacent tissue. A built-in cooling system keeps the patient completely comfortable.

What Onda can treat:

  • Localized fat
  • Cellulite
  • Skin firming

The abdomen, thighs, sides, and the area under the chin can be treated with Onda.


Onda treatment results are visible after just 2 sessions. 3 to 4 sessions spaced one month apart are required to achieve satisfactory results. Sessions last from 8 to 12 minutes, meaning this treatment is quick and noninvasive.

To optimize results, it’s important to maintain a healthy lifestyle throughout the treatment protocol.
