If you've recently added an S-Shape device to your beauty salon, or are considering buying one, you probably already know that it integrates four powerful technologies into one device. However, understanding what this device can do is quite different from knowing how to properly use the S-Shape machine to treat different parts of the body.
This guide provides detailed S-Shape machine treatment plans for each major body part—abdomen, arms, thighs, and double chin. You will see the specific cavitation machine settings, step-by-step treatment procedures, recommended treatment frequencies, and real-world timelines.
Understanding S Shape Treatment Fundamentals
Before delving into the specific solutions for each part, let's quickly review the four core technologies for collaborative operation in the S Shape system:
- Cavitation: The lipolysis cavitation technology breaks down fat cells and releases triglycerides into the lymphatic system for natural metabolic excretion.
- Radiofrequency: Deeply heats the dermis layer, stimulating collagen production and tightening loose skin.
- Vacuum negative pressure: Through suction, it promotes lymphatic drainage and accelerates metabolic excretion.
- Laser lipolysis: Emitting low-energy laser, it penetrates the fat cell membrane, accelerating the release of fat for lymphatic transportation.
Each technique builds upon the previous one; therefore, proper pre-treatment preparation and a reasonable sequence of techniques are crucial for achieving optimal results. For further information on the effects and advantages of the S Shape device, please read our previous feature articles.
S Shape Treatment Protocol for Belly Fat
The abdomen is the most frequently treated area. The S-Shape Machine for Belly Fat treatment targets both subcutaneous fat tissue and stubborn love handles areas on both sides of the waist.
Preparation Before Treatment
- Clean the treatment area to remove oil, solution, and dead skin cells.
- Measure and record waist circumference for before-and-after tracking.
- Review client files to check for cavitation treatment contraindications (pregnancy, pacemaker, side stitch, metal implants, etc.).
Distributed Treatment Process
- Ultrasound gel application: Apply a sufficient amount of ultrasound guiding gel evenly to the abdomen to ensure full coupling between the probe and the skin, and avoid energy loss.
- Cavitation (10–15 minutes): Begin by circling the lower abdomen. Move clockwise around the navel, then use upward, diagonal strokes to treat the fat on the sides of the waist. Start with a lower cavitation energy level and gradually increase it according to the client's comfort.
- Wipe the gel clean and apply essential oil.
- Radiofrequency + vacuum negative pressure (10 minutes): Switch to the vacuum radiofrequency handle. Use slow, controlled pressure to push and pull back and forth on the abdomen, focusing on areas with loose skin or cellulite.
- Wipe the essential oil clean.
- Laser liposuction (20 minutes): Place the lipo laser pad panels onto the abdomen and secure them with elastic bands.
Recommended Settings & Session Frequency
| Parameter | Setting |
|---|---|
| Cavitation energy level | Start from level 3 or 4 and adjust according to comfort. |
| RF suction intensity | Low to medium, adjust according to individual tolerance. |
| Treatment session duration | Total 40–50 minutes |
| Treatment frequency | Twice a week |
| Session timer settings | 8–12 times |
For abdominal fat cavitation treatment, consistency is key. Two treatments per week, with at least three days between sessions, allow the lymphatic system sufficient time to process and eliminate the released fat cells.
S Shape Treatment Protocol for Arms
The S-Shape Machine for Arms treatment primarily targets the triceps area and upper arm circumference. Since the subcutaneous fat in the arms is thin and rich in blood vessels, the parameters must be set low to avoid the risk of burns.
Treatment Steps & Techniques
- Cavitation (5–8 minutes per arm): Push and pull upwards from the elbow towards the armpit, focusing on the back of the triceps. Be careful to avoid joints and superficial blood vessels.
- Radiofrequency (5 minutes per arm): Apply radiofrequency energy in a circular motion to tighten the skin. Avoid bony prominences such as the elbows and shoulder joints.
- Laser liposuction (20 minutes): Place a single laser plate on the back of each upper arm and secure it with an elastic band.
Settings & Frequency
| Parameter | Setting |
|---|---|
| Cavitation energy | 2–3 (low setting for sensitive skin) |
| Radio frequency energy | 2–3 gears |
| Single session duration | Total 40–50 minutes |
| Treatment frequency | Twice a week |
| Complete treatment course | 6–10 times |
The primary goal here is to reduce arm circumference, rather than significantly reducing fat volume. Gradual firming and slimming effects can be expected throughout the treatment, with visible changes typically appearing after the fourth treatment.
S Shape Treatment Protocol for Thighs & Cellulite
Target stubborn fat and cellulite on the inner and outer thighs for thigh gap treatment. Negative pressure radiofrequency is the core function for treating cellulite, and the procedure sequence must be strictly followed: first, fat reduction, then negative pressure radiofrequency.
- Cavitation (10 minutes): First, use vertical techniques to treat the inner thighs, then use circular motions to treat the outer thighs and areas with stubborn fat. The cavitation treatment steps for the thighs follow the same principles as for the abdomen—slow and steady pushing and pulling is more effective than rushed operations.
- Vacuum radiofrequency (10–15 minutes): This is the core tool of the cellulite smoothing program. The negative pressure radiofrequency probe moves slowly, avoiding prolonged fixed-point adhesion, and lifts upwards along the thigh to enhance metabolism and alleviate uneven cellulite skin.
Settings & Frequency
| Parameter | Setting |
|---|---|
| Cavitation energy | 3–5 gears |
| Radio frequency negative voltage intensity | Medium to High |
| Single session duration | 15–20 minutes on each thigh |
| Treatment frequency | Twice a week |
| Complete treatment course | 8–12 times |
S Shape Treatment for Double Chin & Face
Facial treatment requires a completely different approach. The S-Shape Machine for Double Chin is designed for submental fat reduction. Cavitation probes should not be used on the face, as high-frequency liposuction can damage delicate facial tissues. The procedure is performed using an EMS electroporation facial probe.
Treatment Steps
- Cleanse your face: Thoroughly remove makeup and cleanse the treated area.
- Apply a special gel: Use a facial conductive gel.
- EMS + Electroporation Mode (5–8 minutes): For the submental fat area, use the low-frequency mode, making circular motions from the inside out along the jawline. For jawline lifting, switch to RF mode and slide along the jawbone from the chin towards the earlobe.
Facial Security No-Go Zones
- Absolutely avoid the thyroid area (the center of the front of the neck).
- Absolutely avoid the area around the eyes (within the orbital bone).
- Start with the lowest energy level and gradually fine-tune it.
- Each facial treatment should not exceed 10 minutes.
Expected Results Timeline & Before/After
Understanding the S-Shape machine results timeline helps in setting reasonable expectations for customers. Below are the expected outcomes for each stage of the treatment process.
Sessions 1–3: Initial Results
- Slight reduction in circumference (1–4 cm per session).
- The skin immediately felt firmer and smoother after treatment.
- Initially, the main effect is water loss; the fat reduction effect becomes apparent 24–48 hours after treatment.
Sessions 4–8: Visible Changes
- The cumulative effect of a single reduction becomes apparent during measurement.
- Cellulite texture has been significantly improved, especially in the thigh area.
- Skin firmness can be quantitatively measured using before-and-after photos taken with the S-Shape instrument.
Sessions 8–12: Optimal Results
- Maximum girth reduction (typically 3–8 cm in total).
- Significant improvement in skin laxity and skin tone.
- How long cavitation results last: Provided proper maintenance is performed and the customer's weight remains stable, the effect can be maintained for a long time.
We strongly recommend taking before-and-after photos of cavitation treatment at the 1st, 4th, 8th, and 12th treatments to document progress. The optimal number of treatments for most clients is 8–12, followed by maintenance treatments every 4–6 weeks to maintain long-term effectiveness.
Important reminder: Results may vary from person to person and are influenced by factors such as age, basal metabolic rate, and lifestyle. The data above are averages from clinical studies and do not guarantee that everyone will achieve the same results.
Pre & Post Treatment Care Checklist
Before Treatment
- Drink plenty of water (at least 2L per day) 24 hours before treatment.
- Avoid fasting on the day of treatment.
- Pre-treatment photography and circumference measurement data.
- The treatment area should be kept clean and free of skincare product residue.
- Confirm that there are no contraindications (pregnancy, metal implants, heart disease, etc.).
Post-Treatment
- Drink 300–500 ml of warm water immediately to promote metabolism and excretion.
- Maintain a low-calorie, low-fat, high-protein diet for 24–48 hours.
- Refrain from alcohol consumption for 24 hours after treatment (alcohol can interfere with fat metabolism).
- Perform 30 minutes of aerobic exercise (brisk walking or jogging) within 4 hours after treatment.
- Avoid saunas and hot baths for 24 hours after treatment.
Proper post-treatment aftercare directly impacts final results. Clients adhering to the above guidelines see significantly better outcomes versus those ignoring hydration and lymphatic support measures.
FAQ
How often can I do S Shape cavitation treatments?
The body needs approximately 72 hours to process and eliminate the released fat cells through the lymphatic system. We recommend a cavitation treatment frequency of twice a week, with at least a 3-day interval between two treatments on the same site. This issue is also discussed in detail in our CaVstorm vs. S Shape comparison article.
Can I treat multiple body areas in one session?
Yes. However, please note that the total treatment time should not exceed 60–75 minutes. It is recommended to prioritize treating 1–2 main areas (such as the abdomen and thighs) to avoid overburdening the body's metabolism.
What should I avoid after cavitation treatment?
Within 24 hours post-treatment: avoid alcohol, high-fat/high-sugar food, strenuous exercise, saunas and hot baths. Ample warm-water intake, light diet and moderate aerobic exercise help maximize results.
Conclusion
Mastering the S-Shape cavitation protocol for each body part is the dividing line between effective and ineffective treatment. Key points: always follow the correct technical sequence, use instrument parameter settings adjusted for each body part, maintain a consistent treatment frequency, and strictly adhere to the pre- and post-treatment care checklist.
