As an advanced device that uses ultrasonic energy to destroy fat cells, ultrasonic cavitation equipment has shown many advantages in fat reduction and body shaping. However, many consumers and professionals often wonder: What is the Hz of ultrasonic cavitation equipment?

What is ultrasonic cavitation equipment?

Ultrasonic cavitation equipment is a non-invasive fat reduction device that uses low-frequency ultrasonic technology to destroy fat cells by generating cavitation effect. It uses ultrasonic wave bands of specific frequencies to transmit energy to the subcutaneous fat layer, forming tiny bubbles in fat cells. These bubbles gradually expand when they are acted upon by energy, and burst instantly after reaching a certain level, releasing shock waves, thereby destroying the fat cell membrane and causing the fat substances in the fat cells to leak out.

The relationship between cavitation effect and ultrasonic frequency - do you know?

Cavitation effect refers to the phenomenon that in a liquid, ultrasound causes local pressure fluctuations in the liquid, thereby forming and expanding and bursting bubbles. Ultrasonic cavitation equipment uses this effect to physically destroy fat cells. Ultrasonic frequency is an important parameter that determines the intensity and depth of cavitation effect. Generally speaking, the frequency range commonly used for ultrasonic cavitation equipment is between 20kHz and 40kHz.

• Frequencies around 20kHz can produce larger bubbles and stronger destructive power, which is suitable for thicker fat layers;

• Frequencies between 30kHz and 40kHz can provide more uniform and gentle energy distribution, which is more suitable for treatment of facial or local thinner fat layers.

The choice of ultrasonic frequency is directly related to the effect and safety of fat cell destruction. Different frequencies will produce different penetration depths and energy densities for skin and fat tissue, thus determining the scope of application and effect of treatment.

What are the frequency parameters of ultrasonic cavitation equipment?

1. Frequency range of common ultrasonic cavitation equipment

Currently, the operating frequency of most ultrasonic cavitation equipment on the market is between 24kHz and 40kHz. Specifically, different brands and models of ultrasonic cavitation equipment may choose different frequency configurations to achieve the best treatment effect:

• Some devices use a frequency band of 24kHz to 30kHz, which is suitable for deep fat decomposition;

• Others choose a frequency of 35kHz to 40kHz for gentler treatment of the surface and middle layers of skin fat.

The setting of these frequency parameters is determined after comprehensively considering factors such as the thickness of the fat layer, the treatment site, and the patient's tolerance. Usually, professional institutions will adjust the frequency settings of ultrasonic cavitation equipment according to the target site and fat accumulation to achieve the best treatment effect.

2. The impact of frequency on treatment effect

The frequency parameters of ultrasonic cavitation equipment play a key role in the treatment effect. Specifically, different frequencies will affect the following aspects:

• Penetration depth: lower frequencies have better penetration and can act on deeper fat tissue; while higher frequencies mainly act on shallower layers and are suitable for the face or thinner fat layer areas.

•Energy distribution: The higher the ultrasonic frequency, the more uniform the energy distribution, but the energy of a single bubble may be smaller; lower frequencies will produce larger and more concentrated energy shock waves, which are suitable for destroying thicker fat layers.

•Treatment safety: Safety needs to be taken into account when selecting the frequency. Although too low a frequency can quickly destroy fat cells, it may also cause damage to surrounding tissues; and although too high a frequency is gentle, it may not be enough to effectively destroy fat cells. Therefore, professional ultrasonic cavitation equipment will find a balance between 24kHz and 40kHz to ensure both effectiveness and safety.

3. The difference between ultrasonic cavitation equipment and other ultrasonic equipment

Ultrasonic technology is widely used in the medical field, such as ultrasonic diagnosis, ultrasonic lithotripsy, etc. As a device specifically used for fat destruction, ultrasonic cavitation equipment has a unique operating frequency design. Unlike high-frequency ultrasound (MHz level), ultrasonic cavitation equipment uses a low frequency band, mainly to exert the cavitation effect.

High-frequency ultrasound is usually used for imaging diagnosis, with low energy and poor penetration; low-frequency ultrasound can produce sufficient cavitation effect in fat tissue to achieve the purpose of destroying fat cells. Therefore, the frequency of ultrasonic cavitation equipment is set in the range of tens of kHz to meet this specific demand.

How to choose the frequency of ultrasonic cavitation equipment?

1. Target area and fat thickness

When using ultrasonic cavitation equipment for fat reduction treatment, the fat thickness of the target area is an important consideration. For areas with thicker fat layers (such as the abdomen and inner thighs), lower frequencies (such as 24kHz to 30kHz) are usually used to better penetrate the skin and reach deep fat; while for the face or areas with thinner local fat, higher frequencies (such as 35kHz to 40kHz) can effectively destroy fat cells while protecting the skin.

2. Patient tolerance and safety

Each patient has different tolerance to ultrasonic energy. The frequency selection of ultrasonic cavitation equipment must not only consider the treatment effect, but also ensure the safety during the treatment process. Although lower frequencies can improve the fat destruction effect, they may also cause local discomfort or even slight skin redness and swelling; higher frequencies are relatively mild.

Professional beauty institutions usually choose appropriate frequency parameters according to the patient's skin sensitivity and tolerance to ensure that the ideal fat reduction effect is achieved while avoiding unnecessary side effects.

3. Equipment technical parameters and design concepts

Ultrasonic cavitation equipment of different brands and models have different technical parameters, but most equipment will be strictly controlled between 24kHz and 40kHz to take into account penetration depth, energy output and treatment safety. Some high-end equipment also provides adjustable frequency functions, allowing operators to dynamically adjust the frequency according to the treatment site and patient needs, thereby achieving personalized treatment.

The design concept of professional ultrasonic cavitation equipment is often to finely control energy output so that each treatment site can obtain the best energy transfer and cavitation effect.

How to evaluate the frequency effect of ultrasonic cavitation equipment?

1. Fat decomposition effect indicators

The most intuitive indicator to judge the effect of ultrasonic cavitation equipment is the fat decomposition effect. After treatment, the obvious reduction in fat layer thickness, improvement in local body shape, and improvement in skin firmness can all serve as important bases for evaluating whether the frequency of ultrasonic cavitation equipment is reasonable.

Through ultrasonic imaging or professional testing instruments, doctors can quantify the changes in the fat layer before and after treatment, thereby evaluating whether the frequency used has achieved the expected effect.

2. Evaluation of treatment safety

In addition to the effect, the safety of treatment is also an important aspect of evaluating the frequency selection of ultrasonic cavitation equipment. During and after treatment, observing whether the local skin has obvious redness, swelling, bruises or other discomfort reactions can help determine whether the current frequency is too low or too high. Generally speaking, the ideal frequency setting should have no obvious side effects in the treatment area, while the fat decomposition effect is significant.

3. Clinical data and scientific research

At present, many clinical studies have explored and verified the frequency parameters of ultrasonic cavitation equipment. Through a large amount of clinical data and scientific experiments, it has been proved that selecting an appropriate frequency between 24kHz and 40kHz can achieve the ideal fat destruction effect while ensuring the safety of treatment.

Professional journals and research reports have detailed records of the efficiency and safety of fat cell destruction at different frequencies, which provides a reliable scientific basis for the frequency selection of ultrasonic cavitation equipment.

Frequency regulation of ultrasonic cavitation equipment in practical applications

1. Equipment operation and frequency regulation

In actual treatment, the operator can flexibly adjust the frequency of the ultrasonic cavitation equipment according to the specific situation of the patient. Professional ultrasonic cavitation equipment is usually equipped with a digital control panel that allows the operator to select the most suitable frequency between 24kHz and 40kHz. This adjustment function makes the treatment more personalized and can meet the needs of patients with different parts and different fat thicknesses.

• For deep fat decomposition, operators often choose lower frequencies to better penetrate the skin;

• For superficial fat or more sensitive skin areas, higher frequencies may be used to avoid excessive stimulation to the skin.

2. Coordinated regulation of frequency and energy output

In addition to the frequency itself, the energy output of ultrasonic cavitation equipment is equally important. There is a difference in energy output between high and low frequencies. While adjusting the frequency, the operator also needs to pay attention to parameters such as energy density and pulse waveform. Only by properly matching these parameters with the frequency can we achieve the best cavitation effect while ensuring the safety and comfort of the treatment.

Professional institutions often adopt a systematic treatment plan, combining the overall regulation of frequency, energy and treatment duration to achieve efficient and safe fat decomposition.
