What Does A Cavitation Machine Do? 

A cavitation machine is a beauty device that helps contour your body without being invasive. The best thing about this machine is that you can use it in the comfort of your home or spa. If you have been trying to get that perfect body for a while without a major improvement, incorporating a cavitation machine into your busy schedule is only a matter of a few weeks to reveal a slimmer and more sculpted you.

Since it does not involve surgery, there’s no downtime as well. Here is a glimpse of some other cavitation benefits:

• Painless: What better way could you possibly achieve a toned body than a painless treatment? If the fear of needles or anesthesia haunts you, a cavitation machine is the way to go.
• Targeted treatment for stubborn fat: Do you have that stubborn fat in your abdomen, or do you want to target your waistline? No matter the area you want to sculpt, a cavitation machine excels at targeting those trouble zones.
• Safe: There are very few side effects of using a machine. At the most, you may experience some redness, swelling, or bruising, which are often temporary.
• Spa-grade results: You are likely to notice a visible difference right after the first session, with a gradual improvement over the next 3 days.
• Visible difference in skin tone: The machine also helps improve skin tone and texture in the treated area, providing more comprehensive body contouring results.

How Does A 30K Cavitation Machine Work? 

Mychway’s 30k cavitation machine, ideal for professional use, emits ultrasound waves at a frequency of 30kHz, penetrating deep into the subcutaneous fat layer to selectively destroy areas with significant fat deposits. The waves effectively impact the body’s fat cells and create microscopic bubbles. This process, known as cavitation, causes low-density fat cells to rupture and reduce size, giving you a slimmer look. 

The key difference between 30k, 40k, and 80k cavitation is the frequency of ultrasound waves they emit. Using an 80k cavitation machine, the sound waves will vibrate 80,000 times per second. However, the sound waves emitted by a 30k cavitation will vibrate at 30,000kHz.

The effectiveness of the machine depends on the sound waves’ pitch. The lower the frequency, the deeper the penetration. A 30k machine can penetrate up to 12.5 mm to break down fat cells, whereas a 40k machine penetrates 9.4mm deep, and an 80k machine can reach only up to 4mm.

Using a 30k cavitation machine effectively requires you to understand what to do before and after the session clearly. Here’s what you should know:

Pre-Use Guidelines:

• Clean, dirt-free skin is a must before the treatment. It maximizes the results and enhances the absorption of skincare products.
• Exfoliate your skin to ensure the sound waves can effectively penetrate deep.
• Keep your skin hydrated in the days before the treatment.

How to Use the Machine:

• Set up the ultrasonic cavitation device according to the instructions mentioned in the product manual.
• Be familiar with all the settings and controls before starting.
• Put the intensity level on the lowest setting possible.
• Adjust settings as per your comfort level and needs.
• Apply conductive gel evenly onto the treatment area.
• Plug in the device and apply gentle pressure while moving the handle slowly over the treatment area.
• Use circular motions, and don’t stay too long at one spot.
• Take a 15-minute session for effective results.

Post-Use Care:

• Clean your treatment area with a clean piece of cloth.
• A soothing moisturizer of your choice will do.
• Drink plenty of water to ensure faster detoxification.
• Stay out of the sun for 24 hours after your session.
• Wear a body shaper for 8 hours (if possible, optional).

FAQs on 30K Cavitation Machine

Who should choose a 30K Cavitation Machine?

A 30k cavitation machine is ideal for targeting deep fat layers and obvious signs of cellulite, making it suitable for those with a fat thickness between 12.5mm and 9.4mm. Its ability to quickly dissolve fat in a targeted manner makes it a popular choice for those seeking effective body contouring.

How often should you use a 30K Cavitation machine?

If you want to get the best results, you should perform ultrasonic cavitation treatments every 1 to 2 times a week. Each session should not exceed the 15 to 20-minute timeline per body area. Let your body have the time to process and eliminate fat cells effectively.

What precautions do you have to take for 30K Cavitation?

Make sure to avoid consuming alcohol before the days of your first treatment, as it may hinder your body’s metabolism process, reducing the effectiveness of the cavitation technology. Also, refrain from caffeine and stick to a low-calorie diet for 24 hours pre-treatment.

Which is better, 30K or 40K Cavitation?

Both body sculpting machines can be effective. However, it depends on what you want to achieve from the treatment. If you have cellulite and want to improve your skin texture, 30k cavitation is more effective than 40k.
