Onda Pro Coolwaves
in Brentwood, Los Angeles

The award-winning treatment for cellulite and body contouring, trusted across Europe and South Korea, and now at Skin Select.

Onda Pro
is the only aesthetic device powered by Coolwaves technology, a unique 2.45GHz frequency that passes through the skin's surface and delivers controlled heat into the tissue below, where fat and fibrous tissue sit. Your skin stays cool and protected the entire time, so treatment is comfortable from start to finish.

Treatable Areas

Abdomen, thighs, buttocks, arms, knees, and under the chin. Three handpieces focus energy at three different depths, so your treatment can be customized for larger body areas or smaller, precise spots.

How Onda Pro Coolwaves Body Contouring Works

  • Onda Pro delivers Coolwaves, microwaves at a 2.45GHz frequency that move through the skin's surface and focus heat in the subcutaneous tissue where fat cells and the fibrous bands that cause cellulite sit. The surface stays cool and protected while the energy works below.
  • Most patients describe a gentle warmth that builds beneath the skin, similar to a hot stone massage. Results develop over the following weeks as the treated area smooths and contours.

How it Works

We start with an expert assessment of the areas you want to treat, your skin, and your goals. With three handpieces that focus energy at three different depths, your provider builds a plan matched to each area, from larger zones like the abdomen and thighs to smaller spots like under the chin.

During treatment, the handpiece glides over your skin while Coolwaves deliver focused heat into the tissue below. You'll feel a warmth that radiates gently upward while the surface stays cool. Most sessions take between 15 minutes and 1 hour depending on the area.

You can return to work, errands, and social plans the same day. Stay well hydrated, lightly massage the treated area as directed, use SPF, and hold off on alcohol for 3 to 4 days and strenuous exercise for 48 hours. Results continue to develop over the following weeks.

Treatment FAQ

How does Onda Pro work?

Onda Pro is powered by Coolwaves, a unique 2.45GHz frequency that passes through the skin's surface and delivers focused heat into the subcutaneous tissue where fat and the fibrous bands behind cellulite sit. The skin's surface stays cool and protected the entire time.

What does an Onda Pro treatment feel like?

You'll feel a warmth beneath your skin that gradually radiates upward while the device keeps the surface cool and comfortable. Many patients say it feels like a relaxing hot stone massage as the handpiece glides over the skin.

How long does a treatment take?

It depends on the area. A smaller, targeted spot takes less time than the upper thighs, where there is more surface to cover. Most treatments fall within 15 minutes to 1 hour.

How many treatments will I need?

It varies by patient, area, and goals. Typically 2 to 3 treatments are recommended, and some patients see results after a single session. Your provider will map out the right number and timing during your consultation.

How far apart are sessions spaced?

Sessions are spaced 3 to 5 weeks apart depending on the area. After your initial series, maintenance treatments help sustain your results.

Is there anything I should do before my treatment?

Drink plenty of water in the days before your session, and avoid applying moisturizer to the treatment area for a few days prior.

What is the post-treatment care?

Stay well hydrated and lightly massage the treated area as directed by your provider. Use SPF and limit sun exposure, and hold off on alcohol for 3 to 4 days after treatment.

Can I exercise after my treatment?

Movement and light massage are helpful after treatment. Walking is fine right away. Save strenuous workouts for 48 hours after your session.

Am I a good candidate for Onda Pro?

Onda Pro can benefit anyone looking for targeted contouring or improvement in the appearance of cellulite, and it is suitable for most skin types. We'll confirm suitability and build your plan during your consultation.

Is there any downtime?

You can return to your day immediately. Most patients head straight back to work, errands, and social plans.

Can I get Onda Pro if I'm pregnant or breastfeeding?

We do not recommend elective energy-based aesthetic treatments during pregnancy or breastfeeding.

What makes Coolwaves different from other body contouring treatments?

Most energy-based treatments have to pass through and heat the skin's surface to reach deeper tissue. Coolwaves are different: the 2.45GHz frequency is essentially transparent at the surface, so energy concentrates in the subcutaneous layer where fat and fibrous tissue actually sit. Onda Pro is the only aesthetic device powered by this technology, with over 4,500 ONDA devices in use worldwide since 2018.
