| Cryolipolysis | Controlled cooling of subcutaneous fat | Reduction of localized fat bulges without surgery | Abdomen, flanks, thighs, upper arms, submental area | Cooling, pulling or intense cold sensation at the start; temporary numbness is common | Usually none | Changes generally become noticeable over several weeks and may continue for approximately 2–3 months | Applicator fit, cooling control, skin-contact safety, treatment-area eligibility and informed consent are important |
| Radiofrequency Body Contouring | Non-invasive radiofrequency heating | Temporary skin tightening and improvement in body contour appearance | Abdomen, flanks, thighs, buttocks, upper arms | Progressive warmth; the treatment should remain comfortable and controlled | Usually none | Often assessed after a treatment series, with results developing gradually over weeks to months | Temperature monitoring, controlled energy delivery, contraindication screening and operator training are essential |
| High-Intensity Focused Ultrasound | Focused ultrasound energy delivered below the skin | Localized contouring and, in selected systems, skin-tightening support | Abdomen, flanks, thighs and selected smaller areas | Localized heat, tingling or brief discomfort may occur | Usually none | Visible improvement is commonly evaluated over approximately 8–12 weeks | Accurate depth selection, energy calibration, anatomical mapping and avoidance of sensitive structures matter |
| High-Intensity Electromagnetic Muscle Stimulation | Rapidly changing electromagnetic fields that induce muscle contractions | Muscle stimulation, abdominal toning and improvement in muscle definition | Abdomen, buttocks, thighs and calves, depending on the applicator | Strong involuntary contractions followed by muscle fatigue or soreness similar to exercise | Usually none | Muscle tone is generally assessed after multiple sessions and may require maintenance | Screening for implanted electronic devices, metal contraindications and appropriate intensity progression is required |
| Combined RF and Electromagnetic Stimulation | Radiofrequency heating combined with electromagnetic muscle stimulation | Muscle toning with a body-contour and skin-warming component | Abdomen, buttocks, thighs and other approved areas | Warmth together with repeated muscle contractions | Usually none | Results are typically reviewed progressively after a series of treatments | Independent control of heat and contraction intensity, cooling between sessions and safety screening are valuable |
| Vacuum-Assisted RF | Suction massage combined with radiofrequency heating | Improvement in the appearance of cellulite and temporary contour refinement | Thighs, buttocks, hips and abdomen | Rhythmic suction, massage and warmth; bruising can occur in sensitive users | Low; possible temporary bruising | Skin appearance is usually assessed after several sessions and may require maintenance | Suction control, treatment-head hygiene, skin condition assessment and appropriate pressure settings are important |
| Acoustic Wave Therapy | Radial or focused mechanical pressure waves | Improvement in the appearance of cellulite and tissue texture | Thighs, buttocks, hips and selected body areas | Tapping or percussive pulses; intensity should be adjusted to comfort and treatment goals | Usually none | Texture changes are generally evaluated after a course of treatments | Wave type, pressure or energy settings, applicator movement and contraindication screening affect usability |
| Low-Level Light Therapy | Low-intensity red or near-infrared light | Non-invasive support for the appearance of localized body contouring | Abdomen, waist, thighs and upper arms | Usually painless with little or no sensation of heat | None expected | Results, when achieved, are generally gradual and may require repeated treatments | Wavelength, irradiance, treatment distance, eye protection and realistic claims should be clearly documented |
| Non-Invasive Laser Lipolysis | Low-level or controlled laser energy, depending on system design | Localized contour improvement and reduction in the appearance of small fat deposits | Abdomen, flanks, thighs and upper arms | Generally mild warmth; treatment sensation depends on the energy delivery method | Usually none | Assessment is commonly performed several weeks after a treatment series | Laser classification, wavelength, thermal safeguards, eye protection and regulatory indications must be verified |
| Injectable Body Contouring | Injection of an approved active substance into selected subcutaneous fat | Reduction of small, localized fat deposits | Only areas covered by the applicable local authorization, commonly the submental region for certain products | Multiple injections; swelling, tenderness and bruising may occur | Several days to weeks may occur | Improvement is gradual and may require more than one treatment session | Medical qualification, product authorization, injection anatomy, sterile technique and adverse-event management are critical |
| Surgical Liposuction | Surgical removal of subcutaneous fat using cannulas | More substantial reshaping of selected body areas | Abdomen, flanks, thighs, hips, back, arms and other surgeon-approved areas | Performed under anesthesia or appropriate sedation in a surgical setting | Typically weeks | Swelling gradually decreases over weeks to months; final contour may take several months | Requires qualified surgical care, anesthesia support, postoperative monitoring and appropriate patient selection |
