Key points

Onda Coolwaves in Geneva 

Onda Coolwaves uses specific microwaves to target and break down fat cells. Benefits include :

  • Proven effectiveness : visibly reduces fat deposits and cellulite from early sessions.
  • Quick, comfortable sessions.
  • Lasting results : body contouring, firmer, more toned skin and a harmonious figure without cellulite.
  • No recovery period is needed.
  • A safe, non-invasive approach. An effective alternative to cosmetic surgery for fat deposits.

What are the contraindications
to Onda Coolwaves ?

Hydrafacial

Onda Coolwaves is safe and well tolerated by most patients, but there are contraindications.

  • Pregnancy and breastfeeding.
  • Implantable electronic devices.
  • Skin disorders : active infections, lesions or inflammation in the treatment area.
  • Coagulation disorders or anticoagulants : not strictly a contraindication, but individual assessment is needed.

What are the indications for
Onda Coolwaves ?

The device's microwaves act at several levels.

  • Action on cellulite : microwaves destroy connective septa between fat cells (traction from these septa causes orange-peel texture).
  • Localised fat reduction : microwaves damage fat cell membranes, and cells are then eliminated through physiological mechanisms.
    Ideal for areas such as abdomen, thighs, buttocks and arms where fat persists despite diet and exercise.
  • Action on skin laxity : microwaves immediately shrink collagen and elastin fibres and stimulate new fibre synthesis. Tissues are toned, but the extent of firming varies.
  • Improved skin quality : smoother, firmer skin.
  • Body contouring : the figure is slimmed and sculpted without surgery.

Which body areas can Onda Coolwaves treat ?

Treated areas are the arms, abdomen, thighs, buttocks, hips and knees.

What happens during a
Onda Coolwaves in Geneva

The patient lies comfortably on the examination couch while a handpiece is swept over the area.
The device has two handpieces : a superficial one for laxity and cellulite, and a deep one for cellulite and fat deposits.
These deliver magnetic waves only to targeted areas, preserving adjacent tissues. An integrated cooling system prevents skin burns.
Each area takes approximately eight minutes.
Treatment is painless.

Protocol

A protocol ensures optimal, lasting results.
The initial phase comprises four sessions spaced three weeks apart.
Maintenance involves one session every four months.

Treatments that can be combined with Onda
Coolwaves

Hydrafacial

To optimise results, Onda Coolwaves can complement other aesthetic procedures within comprehensive care for the figure and skin quality.

  • Cryolipolysis : ideal for stubborn fat bulges, it can complement Onda Coolwaves for even more effective contouring.
  • Body peels : improve skin quality. They remove dead cells for smoother, more radiant skin.
  • Emsculpt : the ideal complement for optimal muscle strengthening.

Are there recommendations
before and after a session of
Onda Coolwaves ?

Follow recommendations before and after sessions for optimal results without side effects.

  • Avoid irritating creams or lotions on treatment areas for at least 24 hours before and after.
  • Sun protection : apply broad-spectrum sunscreen to treated areas.
  • Avoid intense activity for 24 hours afterwards, as it may worsen redness or swelling.
  • Session attendance : follow the schedule established at your initial consultation.
  • Aftercare : use recommended creams to soothe and hydrate after each session.
