Achieving a healthy weight does not always eliminate stubborn localised fat deposits. Certain areas may be more resistant to diet and exercise. Non-surgical aesthetic treatments such as fat freezing and HIFU are designed to reduce fat in targeted areas by gradually reducing fat cell volume.
In this guide, you will learn:
- How cryolipolysis (fat freezing) works at a cellular level
- How the body naturally processes and eliminates treated fat cells
- The differences between cooling-based fat reduction and ultrasound-based HIFU treatments
- Expected timelines for visible contour changes and results
Reaching your goal weight is an important achievement, but it does not always eliminate stubborn areas of localised fat, such as the lower abdomen or flanks.
Because the body does not allow precise “spot reduction” through exercise alone, these areas may persist even in otherwise healthy individuals. Non-surgical fat reduction treatments such as cryolipolysis and HIFU are designed to help reduce fat in targeted areas by gradually decreasing the number of fat cells, supporting overall body contouring goals.
At Telma Skin Clinic in Broadmeadows, we offer non-surgical, medical-grade fat reduction therapies. Using controlled thermal/uktrasound technologies, we target fat cells (adipocytes) to induce natural breakdown and gradual elimination by the body. This approach helps reduce stubborn localised fat and refine body contours, with minimal downtime for most clients.
How Does Fat Reduction Treatment Work?
Fat cells (adipocytes) respond differently to controlled temperature changes compared to surrounding skin, nerve, and muscle tissue. This allows non-surgical technologies such as cryolipolysis (cooling) and HIFU (focused ultrasound energy) to selectively target fat cells while minimising damage to other structures.
When exposed to controlled cooling or thermal energy, fat cells are gradually injured and undergo a natural process called apoptosis (programmed cell death). Over the following weeks to months, the body’s immune system identifies and processes these cells as waste, with clearance occurring through normal metabolic pathways, including the lymphatic system and liver.
The treated area typically shows a reduction in fat cell volume, leading to improved body contour. While the fat cells in the treated area are significantly reduced in number, remaining cells can still expand with weight gain, so results are best maintained with a stable lifestyle.
Targeting Localised Fat With Cryolipolysis
Cryolipolysis, commonly known as fat-freezing, is a non-surgical treatment that uses vacuum applicators to gently draw a “pinchable” area of tissue into a cooling chamber, where it is exposed to controlled low temperatures.
Clinical literature, including summaries published by sources such as Harvard Health Publishing, describes how controlled cooling causes crystallisation of lipids within fat cells. This process triggers gradual injury to adipocytes (fat cells), while surrounding skin and tissue remain largely unaffected due to their higher resistance to cold.
Over the following weeks to months, the body naturally processes and clears the damaged fat cells through normal metabolic pathways, resulting in a reduction of localised fat in the treated area.
Cryolipolysis is commonly used to address stubborn areas such as the lower abdomen and flanks, where fat deposits may be resistant to diet and exercise. Clinical studies have reported fat layer reductions of up to approximately 20–25% in treated areas after a single session in some cases, though individual results vary.
Overcoming Stubborn Abdominal Fat
The midsection is commonly affected by fat accumulation due to a combination of genetic, lifestyle, and hormonal factors, including hormones such as cortisol. Patients often ask whether fat reduction treatments can help with abdominal fat. The clinical answer is that these treatments may help reduce localised subcutaneous fat in appropriately selected candidates.
The abdominal region contains two main types of fat:
- Visceral fat, which lies deeper within the abdominal cavity and surrounds internal organs
- Subcutaneous fat, which is the soft, pinchable layer located just beneath the skin
Visceral fat is primarily influenced by overall metabolic health and tends to respond to systemic changes such as sustained weight loss through diet, exercise, and lifestyle modification.
Subcutaneous fat, however, can be targeted with non-surgical body contouring treatments such as cryolipolysis and HIFU. These technologies are designed to reduce fat cells in treated areas by controlled thermal effects, with the goal of improving localised body contour.
Areas such as the lower abdomen and flanks are commonly treated because they often contain accessible, pinchable subcutaneous fat. However, individual response varies depending on anatomy, lifestyle, and treatment parameters.
Selecting the Best Non-Surgical Fat Reduction Treatment
The most suitable non-surgical fat reduction treatment depends on several factors, including the type and distribution of fat, skin quality, and individual treatment goals.
Broadly, body contouring approaches can be considered in two categories:
Fat Freezing (Cryolipolysis – Cold):
Cryolipolysis is generally used for larger, pinchable areas of localised fat where the skin has good elasticity. It works by controlled cooling that targets fat cells, leading to gradual reduction in fat volume in treated areas over time.
HIFU (High-Intensity Focused Ultrasound – Heat):
HIFU delivers focused ultrasound energy to deeper layers of subcutaneous tissue, causing thermal and mechanical disruption of fat cells. In addition to its fat-reduction effects, it may also stimulate collagen remodelling in the dermis, which can support mild skin tightening over time.
A clinical assessment is recommended to determine which treatment is most appropriate for your anatomy and goals, as results vary between individuals.
How Long Does It Take to Start Seeing Fat Reduction Results
How Long Does It Take to See Fat Reduction Results?
Neither cryolipolysis nor HIFU physically removes fat from the body during the treatment session. Instead, these technologies work by damaging fat cells, which are then gradually processed and cleared through the body’s natural metabolic and immune pathways.
The body begins initiating this clearance process within days following treatment. However, visible changes develop gradually as the body continues to break down and remove the affected fat cells.
Many patients begin to notice subtle changes from around 3–6 weeks post-treatment, with improvements continuing over time. Peak results are typically observed around 8–12 weeks, depending on the treatment area, individual response, and lifestyle factors.
If you are struggling with stubborn, localised fat that is resistant to diet and exercise, a clinical assessment can help determine whether fat freezing or HIFU may be suitable for your goals.

FAQS
How does fat reduction treatment work?
Non-surgical fat reduction treatments use controlled cooling or focused ultrasound energy to damage fat cells beneath the skin. These damaged fat cells undergo a natural process called apoptosis (cell death) and are gradually cleared by the body through normal metabolic and immune pathways over time.
Is fat freezing effective for stubborn fat?
Cryolipolysis has been shown in clinical studies to reduce the number of fat cells in treated areas. It can be effective for localised, pinchable fat pockets that are resistant to diet and exercise. Results are long-lasting, provided weight remains stable.
What is the best non-surgical fat reduction treatment?
The most suitable treatment depends on the individual and the tissue being treated. Cryolipolysis is generally used for larger, pinchable areas of localised fat, while HIFU uses focused ultrasound energy to reduce smaller fat deposits and may also support mild skin tightening through collagen remodelling.
How long does it take to see fat reduction results?
Because the body gradually processes and clears the damaged fat cells, early changes may be noticed from around 3–6 weeks after treatment. Results continue to develop over time, with optimal contouring typically seen around 8–12 weeks.
Can fat reduction treatments help with belly fat?
Fat reduction treatments may help reduce localised subcutaneous fat in the abdominal area. The lower abdomen is commonly treated because it often contains pinchable fat that can respond well to controlled cooling or ultrasound-based technologies, depending on individual suitability.
