Refining the lower face, without invasive treatment

Fullness beneath the chin and a softening of the jawline are common concerns, often referred to as submental fat or a ‘double chin’. While it can be associated with weight, it’s just as often influenced by genetics, ageing, or hormonal changes.
For many, the goal isn’t dramatic change, but subtle refinement; a more defined profile, a cleaner jawline, and improved skin quality.
ONDA Coolwaves offers a non-invasive way to address these concerns. By targeting both fat and skin structure, it provides a more considered approach to contouring the lower face.
What Is ONDA Coolwaves?
Targeted microwave technology for precision contouring
ONDA Coolwaves uses patented Coolwaves™ microwave technology, specifically developed for aesthetic treatments.
Unlike more traditional energy-based devices, Coolwaves are designed to selectively target fat cells while protecting the surrounding skin. This allows the treatment to work deeper within the tissue, where structural changes occur.
In the face and submental area, this enables:
- Reduction of localised fat beneath the chin
- Support for skin tightening and firmness
- Improved definition along the jawline
The treatment is non-invasive, with minimal downtime, and is designed to deliver controlled, precise results in smaller, more delicate areas.
While this article focuses on its application for the face, our guide to 'A Smarter Approach to Cellulite & Fat Reduction' explores how the same technology can be used to target stubborn fat and cellulite on the body.
How It Targets Submental Fat (Double Chin)
Reducing fullness beneath the chin

Submental fat refers to the accumulation of fat beneath the chin, which can soften the profile and reduce definition between the face and neck.
ONDA Coolwaves works by delivering controlled microwave energy into this area, where it:
- Selectively heats and disrupts fat cells
- Breaks down their structure, allowing the body to process and eliminate them naturally
- Targets the area with precision, making it suitable for smaller zones like the under-chin
Because of this level of control, the treatment is particularly effective for refining the jawline, rather than altering the face more broadly.
Results develop gradually, creating a more sculpted, balanced profile that feels in harmony with your natural features.
Skin Tightening & Jawline Definition
Supporting structure as well as contour

Alongside fat, skin laxity plays a key role in how defined the lower face appears. As collagen levels decline, the skin can begin to lose firmness, contributing to a softer jawline.
ONDA Coolwaves supports this by stimulating collagen remodelling and tissue contraction within the treated area.
This helps to:
- Improve skin firmness and elasticity
- Enhance the appearance of the jawline
- Support a smoother transition between the face and neck
Rather than adding volume or creating lift in the way injectable treatments might, ONDA focuses on refining what is already there - creating a result that feels subtle, balanced, and natural.
Onda Coolwaves vs Fat Dissolving Injections
How does it compare?
| Feature | ONDA Coolwaves | Fat Dissolving Injections |
|---|---|---|
| Fat reduction | Yes | Yes |
| Skin tightening | Yes | No |
| Invasiveness | Non-invasive | Injectable |
| Comfort | Generally comfortable | Can be uncomfortable |
| Downtime | Minimal | Swelling and bruising common |
| Precision | High, controlled energy delivery | Moderate, product diffusion |
| Treatment approach | Fat + skin quality | Fat only |
ONDA offers a more comprehensive approach, particularly for those looking to improve both contour and skin quality, without the downtime associated with injectable treatments.
Who Is It Best For?
Ideal for subtle refinement
ONDA Coolwaves is best suited for those looking to refine and define the lower face, rather than make significant structural changes.
It is particularly effective for:
- Mild to moderate submental fat (double chin)
- Early skin laxity
- Loss of jawline definition
It may not be suitable for those with more significant excess skin, where alternative treatments may be recommended.
The ideal approach is always tailored, ensuring the treatment aligns with both your anatomy and your desired outcome.
