Everyone dreams of a perfectly toned body they can show off, especially in summer, but following a strict diet and exercise routine to achieve that shape can be hard. Food lovers deserve to feel good about their bodies too, don't they?
That’s why many people look for quicker, easier ways to improve how their bodies look and are turning to cavitation machines. Cavitation machines are tools used to reduce the appearance of cellulite and sculpt the body.
Two popular cavitation machines are CaVstorm and S Shape. The question is: which one is right for your salon business? Let’s look at their differences, benefits, and potential side effects so you can make the best choice for your clients.

What is the CaVstorm Cavitation 3.0 machine?
CaVstorm Cavitation 3.0 is a body-contouring machine that uses ultrasonic cavitation technology to address unwanted fat. Its updated technology and working mechanism are designed for body toning.
How does CaVstorm work?
Based on Cavitation 2.0 technology, CaVstorm Cavitation 3.0 has been updated with a new ultrasonic transducer with higher power output that covers the entire transducer.
It uses sound waves at a frequency of 40,000 hertz. As the sound waves enter the body, they create movement between fat cells. This process causes fat deposits to turn into a liquid form that is then eliminated naturally through the lymphatic system.
What is an S Shape machine?
Advances in aesthetics technology have changed the way we approach beauty treatments. One such innovation is the S Shape machine. This device offers a non-invasive option for body contouring, cellulite reduction, and skin rejuvenation.
How does S Shape cavitation work?
S Shape uses a non-invasive frequency of 30,000 hertz to rapidly vibrate fat cells, breaking them down into free fatty acids and glycerol. Vacuum and radio frequency treatment then increase blood circulation and metabolism, helping eliminate the contents from the body and reduce fat.
Using 30 kHz cavitation, the S Shape machine offers another option for salons looking to expand their body-contouring services.
Potential benefits of cavitation machines
Cavitation machines, also known as ultrasonic or fat cavitation machines, have gained popularity in aesthetics and beauty treatments. Effectiveness and specific benefits may vary by individual and machine, but potential benefits include:
- Non-invasive fat reduction: Cavitation machines offer a non-invasive alternative to procedures such as liposuction. They may help reduce localized fat deposits in areas such as the abdomen, thighs, hips, arms, and buttocks without incisions or anesthesia.
- Body contouring: Breaking down fat cells can help contour and shape the body for a more sculpted appearance.
- Cellulite reduction: Cavitation treatments may help reduce the appearance of cellulite by targeting fat beneath the skin's surface and smoothing dimpled texture.
- Skin tightening: Cavitation machines may also stimulate collagen production in treated areas, contributing to firmer-looking skin.
- Quick treatments: Cavitation treatments are generally described as painless and do not typically require downtime. Sessions can often be completed within 30 to 60 minutes.
Individual results may vary. Body composition, lifestyle, diet, and exercise can influence the outcome of cavitation treatments. Consult a qualified professional before undergoing aesthetic treatment to assess whether it suits your needs and goals.
What can these machines bring to your beauty business?
- Start a beauty business: If you want to establish a mini beauty studio, CaVstorm and S Shape machines can provide ways to explore the beauty market.
- Expand your services: If you want to improve your existing spa services, these machines may help you offer body-sculpting treatments to your clients.
- Improve customer satisfaction: Body sculpting, skin tightening, and anti-aging treatments are among the services available for the body and face. Offering options suited to your clients' needs may improve their experience.
- Consider your investment: Equipment costs should be weighed against the services you plan to offer and the demand from your customers.
Potential side effects of these machines
CaVstorm side effects
While CaVstorm is generally considered non-invasive, not following proper care instructions may lead to side effects. Examine each individual before treatment and follow the device instructions. Potential effects include:
- Bruising
- Redness
- Swelling
- Discomfort
S Shape side effects
S Shape is also a non-invasive body-sculpting device, but individuals may react differently. Potential effects include:
- Temporary redness
- Irritation
- Bruising
- Swelling
- Numbness
- Skin sensitivity
Which machine is right for your salon?
Choose the machine that best suits your business based on your clientele and their needs. If your salon serves people looking to contour both their body and face, including the jawline, S Shape 30K may be a better fit.
CaVstorm 3.0 may appeal to clients with busy schedules who want a body-focused treatment without a long recovery period.
Cost may also factor into your choice. The price ranges cited here are $1,900–$2,499 for CaVstorm 3.0 and $659–$1,799 for S Shape. Check current prices before deciding, and don't base your choice on price alone: the machines offer different features.
Consider what your customers are looking for, then choose the machine that meets most of your salon's needs. Each has something different to offer.
