What is cavitation treatment and how does it work?

Ultrasonic cavitation is a non-invasive body contouring treatment that uses low-frequency ultrasound waves to break down fat cells in the body.

They create a phenomenon known as cavitation, which is the formation and collapse of small bubbles in a liquid. When it happens, they make “waves” that can break down the fat cells. After, they are naturally eliminated from the body through the lymphatic system.

The treatment is often used on areas of the body such as the thighs, buttocks, and abdomen to reduce the appearance of cellulite and to contour the body.

It is typically non-invasive and does not require the use of anesthesia. Sessions can be performed in a doctor's office, spa, or even at home. The treatment time can vary depending on the size of the area being treated. Some people may experience mild discomfort or other side effects, but it is generally well-tolerated.

Benefits of cavitation based on scientific research

Cavitation is a cosmetic procedure that is claimed to be able to reduce body fat and cellulite, improve skin texture, tighten and tone the skin. 

Below we will take a closer look at these benefits based on scientific research.

  • Reducing the appearance of cellulite

Cellulite is a common condition that affects the appearance of the skin, causing it to have a dimpled or “orange peel”. It is caused by fat deposits that push against the connective tissue beneath the skin. 

Ultrasonic cavitation can help to reduce the appearance of cellulite by breaking down fat cells and promoting the body's natural removal of them [1].

  • Reducing the size of fat deposits

Ultrasonic cavitation can help to reduce the size of fat deposits in the body, leading to a slimmer and more contoured appearance. Also, it is often used in conjunction with other treatments, such as radio frequency therapy to enhance the overall effectiveness of the procedure [2]. 

  • Firming and toning the skin

Ultrasonic cavitation may help to improve the elasticity and tone of the skin. This can lead to a firmer, smoother, and more youthful appearance, particularly in areas where the skin has lost elasticity due to aging or weight loss. 

It works by stimulating the production of collagen and elastin, two proteins that play a key role in the structure and elasticity of the skin. By increasing their production, ultrasonic cavitation may help to improve the tone and texture of the skin, making it more firm and supple [3]. 

It is important to note that ultrasonic cavitation should not be used as a substitute for a diet and regular exercise, which are essential for maintaining healthy body weight and overall well-being.

Before and after results

Ultrasonic cavitation is designed to reduce the appearance of cellulite and fat deposits, resulting in a smoother, more toned appearance. Before and after results vary depending on the individual, but many people experience a significant reduction in fat and an improvement in the overall tone and contour of their skin.

Pros and cons of ultrasonic cavitation

Ultrasonic cavitation has several potential pros and cons to consider before undergoing treatment.

βœ… Non-invasive: The treatment is non-invasive, meaning it does not involve any incisions or injections. This can be appealing for people who are hesitant to undergo more invasive procedures such as liposuction.
βœ… Quick: Each treatment session typically lasts only 30-60 minutes, making it a convenient option for people with busy schedules.
βœ… No downtime: There is no recovery period required after the treatment, so people can return to their normal activities immediately.
βœ… Minimal side effects: Most people do not experience any significant side effects from ultrasonic cavitation, and any that do occur are usually mild and temporary.
βœ… Can be used on multiple areas of the body: The treatment can be used on various areas of the body, including the abdomen, thighs, buttocks, and upper arms.
❌ Results may vary: Some people may see better results than others, and they may not be as dramatic as those achieved with more invasive procedures such as liposuction.
❌ Not permanent: While the treatment may produce short-term improvements in the appearance of cellulite and skin firmness, the results are not permanent and should be maintained with other activities.
❌ Not suitable for everyone: Some people may not be good candidates for the treatment due to medical conditions or medications that they are taking (for example, people with pacemakers or metal implants, individuals with certain skin conditions such as eczema or rosacea)

Side effects and risks

Ultrasonic cavitation is generally considered to be a safe procedure, but like any medical treatment, it can have certain risks and side effects. 

Some potential side effects of ultrasonic cavitation include:

  • Pain or discomfort: Some people may experience pain or discomfort during the procedure, particularly if the sound waves are focused on a sensitive area of the body.
  • Bruising: Some people may develop bruises on the skin after undergoing ultrasonic cavitation, although this is usually temporary (goes away in one to two weeks).
  • Swelling: Swelling occurs when fluid accumulates in the tissues and can cause the treated area to feel swollen or tender. This is typically a temporary side effect that should resolve within a few days.
πŸ“Œ Note:
The risks and side effects of ultrasonic cavitation may vary depending on the individual and the specific procedure. It is always a good idea to speak with a healthcare professional before starting any new treatment.

Can ultrasonic cavitation cause cancer?

There is no evidence to suggest that ultrasonic cavitation can cause cancer or increase the risk of developing this condition.

However, people with cancer or a history of this condition may have some contraindications for ultrasonic cavitation. For example, people undergoing chemotherapy or radiation therapy may be at an increased risk of side effects from ultrasonic cavitation. In addition, individuals with certain types of cancer, such as breast cancer, may have metal implants or devices that could be affected by the procedure.

Contraindications for cavitation treatment

There are certain situations in which ultrasonic cavitation may not be appropriate or contraindicated. Some potential contraindications for cavitation treatment include:

❌ Pregnancy and breastfeeding

Ultrasonic cavitation is generally not recommended for pregnant and breastfeeding women, as the effects of the procedure on the developing fetus and lactation are not fully understood.

❌ Metal implants or pacemakers

People with metal implants or pacemakers should not undergo ultrasonic cavitation, as the procedure may interfere with the functioning of these devices.

❌ Skin infections

People with active skin infections or open wounds should not undergo ultrasonic cavitation, as the treatment can exacerbate these conditions.

❌ Certain medical conditions

People with certain medical conditions, such as uncontrolled high blood pressure, diabetes, or a history of blood clots, should not undergo ultrasonic cavitation.

Discuss your medical history and any current health conditions with a healthcare professional before starting ultrasonic cavitation. They will be able to determine whether the procedure is appropriate for you and identify any potential risks.
