Ultrasonic Cavitation Warning (Risks & Precautions)

Is there any risk associated with ultrasonic cavitation? Can there be damage to organs? Is ultrasonic cavitation safe? Is ultrasonic cavitation dangerous? Can ultrasonic cavitation cause cancer?

Many people have questions about ultrasonic cavitation, yet what is the truth? In this article from myChway, let's answer together.

Clinical Evidence and Safety of Ultrasonic Cavitation

Ultrasonic cavitation is widely recognized as a safe, non-invasive cosmetic procedure when used correctly. Unlike surgical liposuction, it does not require incisions, anesthesia, or long recovery periods. Multiple studies and clinical observations have confirmed that low-frequency ultrasound waves (typically 30–80 kHz) can target subcutaneous fat cells without affecting underlying organs or tissues.

Key points from research:

• Effectiveness: Studies show a measurable reduction in localized fat and circumference after multiple sessions, often accompanied by smoother skin and improved cellulite appearance.
  

• Side effects: Minor, temporary side effects such as mild redness, tenderness, or slight swelling may occur but usually resolve within hours to a few days.
  

• Organ safety: At recommended intensities, ultrasound waves penetrate only the fat layer and do not damage internal organs.
  

• Cancer risk: Ultrasound used in cavitation is non-ionizing, meaning it does not cause DNA mutations and has no evidence of increasing cancer risk.
  

In summary, when performed correctly—whether at home with proper devices or in a professional setting—ultrasonic cavitation is considered safe and low-risk for healthy individuals.

Does Ultrasonic Cavitation Have Any Side Effects on Health?

Ultrasonic cavitation fat removal is an FDA-approved procedure. Global statistics released in 2018 by the American Society of Aesthetic Plastic Surgery show that non-invasive techniques for fat reduction are gaining more traction than surgical procedures.

To answer the question, we asked at the beginning, can it cause cancer? Does it cause damage to organs? Does ultrasonic cavitation have an effect? The answer is, no, no, yes.

1.1 Can ultrasonic cavitation cause cancer?

Currently, no scientific evidence suggests that ultrasonic cavitation can cause cancer. This blog has more details on the clinical studies of ultrasonic cavitation therapy.

Cancer is generally is caused by genetic mutations and exposure to carcinogenic substances or radiation. While ultrasound waves can generate heat and pressure, the energy levels used in ultrasonic cavitation treatments are considered safe and incapable of causing cancer.

1.2 Does ultrasound cavitation damage organs?

The ultrasound waves used in the procedure are not powerful enough to damage organs directly, and there is a risk of tissue damage if the treatment is performed incorrectly or at too high of an intensity. Ultrasonic cavitation is a non-invasive cosmetic treatment, it is generally considered to be a safe procedure when performed with correct use. This ultrasonic cavitation warning is not valid.

1.3 Is ultrasonic cavitation effective?

There is some evidence to suggest that ultrasonic cavitation may be an effective treatment for reducing the appearance of cellulite and localized fat deposits. Studies have shown that ultrasonic cavitation can lead to a reduction in circumference measurements and improvements in skin texture and appearance. 

Who Can Use Ultrasonic Cavitation?

Generally, individuals who are in good overall health and have localized areas of fat or cellulite may be suitable candidates for ultrasonic cavitation.

When Should Ultrasonic Cavitation Be Avoided?

However, certain factors may make a person unsuitable for the treatment. Here are some ultrasonic cavitation warnings to be aware of including:

• Pregnancy: Ultrasonic cavitation is not recommended for pregnant women due to the potential risks to the developing fetus.
• Breastfeeding: The safety of ultrasonic cavitation during breastfeeding is not well established, so it's recommended to avoid the treatment until after the breastfeeding period.
• Medical conditions: Individuals with certain medical conditions, such as liver or kidney disease, should avoid ultrasonic cavitation, which may place additional stress on these organs.
• Metal implants: The treatment should not be performed on areas of the body with metal implants, as the ultrasound waves can cause discomfort or damage.

Home Use vs Professional Treatment: Safety Considerations

While professional clinics offer trained technicians, calibrated machines, and real-time monitoring, home devices provide a convenient and cost-effective alternative. Both methods are safe when used correctly, but home users must follow the instructions carefully to avoid common mistakes.

Best practices for safe home use:

• Use the device on clean, intact skin only.
  

• Keep the device moving continuously; do not stay in one spot for more than the recommended time.
  

• Adjust intensity based on fat thickness and skin sensitivity.
  

• Avoid using on areas with metal implants or broken skin.
  

• Stick to the recommended treatment frequency (usually 2–3 times per week for the first month, then once per week).
  

Adhering to these precautions ensures safe, effective, and long-lasting results while minimizing the risk of burns or tissue irritation.

What are the Ultrasonic Cavitation Risks You Will Face When Misusing It?

Improper use of an ultrasonic cavitation machine can lead to potential risks and complications, including:

Burns: Ultrasonic cavitation can cause burns if the ultrasound waves are applied at too high of intensity or if the device is left in one area for too long. Although the energy of the home device is set at a low level, the same care must be taken not to overuse it.

Skin damage: The ultrasound waves can damage the skin if the device is applied too aggressively or if the skin is too thin or sensitive.

Tissue damage: The ultrasound waves can cause damage to underlying tissues, such as muscle or connective tissue if the device is too high of an intensity.

Pain or discomfort: Improper use of the device can cause pain or discomfort during treatment, which may persist after treatment.

Nerve damage: The ultrasound waves can damage nerves if the device is applied too high, which can result in numbness, tingling, or loss of sensation in the affected area.

Ineffective treatment: Improper use of the device can lead to ineffective treatment, meaning the desired results may not be achieved.

If you experience any unusual symptoms or complications after undergoing ultrasonic cavitation, it's important to seek medical attention immediately.

How to use an ultrasound cavitation machine safely?

The machine should only be used under specific circumstances, as outlined below:

A trained person should use the machine: You can buy cavitation machines for home use but read the instructions carefully before using them to ensure you already know how to use them. If you go to an aesthetic center for treatment, ensure your therapist is licensed.

The machine should be used on specific areas of the body: Ultrasonic cavitation is most commonly used on areas of the body with localized fat deposits, such as the thighs, hips, and abdomen.

The machine should be used at appropriate energy levels: The intensity of the ultrasound waves should be adjusted according to the thickness of the fat layer and the sensitivity of the skin to avoid causing tissue damage. The energy level of the home device has been set to a low level.

Which body parts are best suited for ultrasonic cavitation?

Ultrasonic cavitation can be used on various parts of the body to help reduce the appearance of cellulite and contour the body. The most commonly treated areas include:

Abdomen: Ultrasonic cavitation can help reduce belly fat and contour the stomach area.

Thighs: The treatment can be used to target stubborn fat in the inner and outer thighs.

Buttocks: Ultrasonic cavitation can help lift and contour the buttocks.

Arms: The treatment can be used to target fat on the upper arms and reduce the appearance of "bat wings."

Back: Ultrasonic cavitation can help reduce back fat and contour the area.

Love handles: The treatment can help target and reduce stubborn fat around the waistline.

It's also important to consult with a qualified practitioner to determine if you are a good candidate for the treatment.

What is the best frequency to use an ultrasonic cavitation machine?

Generally, frequencies between 30 and 80 kHz are used for body contouring and fat reduction. Lower frequency cavitation machines such as 40kHz may be better suited for larger areas or areas with more stubborn fat, as they provide deeper penetration and target a wider range of tissues. On the other hand, higher frequency cavitation machines such as 60kHz or 80kHz may be better suited for smaller areas or more delicate areas of the body, as they provide more superficial treatment and are less likely to cause discomfort.

How to choose a suitable ultrasonic cavitation machine if you use it yourself at home?

Choosing a suitable ultrasonic cavitation machine for home use requires careful consideration of several factors, including:

Power: The machine should be powerful enough to deliver effective results, but not so powerful that it causes harm or discomfort. Look for a machine with a power output of between 30W and 50W.
