Contouring reshapes set areas near a stable weight; it is not weight loss. Each page is reviewed by Dr Sin Yong. Reviewed by Dr Sin Yong, Medical Director, IN Eternity Clinic · Updated 28 October 2026 Key facts - **Body devices and protocols:** Onda Pro (DEKA Coolwaves microwave), Z Sculpt (electromagnetic muscle stimulation) and the 4K Body Lift, the clinic’s mapped RF microneedling protocol. - **Not weight loss:** body contouring reshapes set areas in people near their target weight; it does not replace weight loss. - **Muscle tone:** Z Sculpt is usually given as a course of four to six sessions to build tone in the treated zone. - **Limits:** significant loose skin after pregnancy or large weight loss may need a surgical opinion, which is said plainly at assessment. - **Not offered:** fat freezing (cryolipolysis) is explained in the guides below but not offered at IN Eternity Clinic. Start here ## Which page should you read first? Start with body concerns if you want the causes explained, or with body contouring if you already know you want fat or contour treated. - [body concerns](https://ineternityclinic.com/concerns/body/) — Love handles, a sagging tummy, cellulite, stretch marks, back acne and underarms, each matched to its cause. - [body contouring in Singapore](https://ineternityclinic.com/4k-body-lift/) — The 4K Body Lift, the clinic’s mapped RF microneedling protocol, compared with Onda Pro and Z Sculpt. - [body sculpting in Singapore](https://ineternityclinic.com/blog/body-sculpting-singapore-guide/) — Radiofrequency, microwave and muscle stimulation compared by area, and when surgery fits. How to choose ## How do you choose a body treatment? Choose by what is actually there: fat, loose skin, soft muscle, dimpling or marks each need a different approach. | What you notice | Usually considered | Read first | |---|---|---| | A pinchable pocket of fat that stays despite diet and exercise | Onda Pro or the 4K Body Lift | [stubborn fat](https://ineternityclinic.com/conditions/stubborn-fat/) | | Loose, crepey skin on the tummy after pregnancy or weight loss | Tightening; a surgical opinion if skin excess is marked | [sagging tummy treatment](https://ineternityclinic.com/sagging-tummy-treatment-singapore/) | | Dimpling on the thighs or buttocks | Cellulite graded first, then Onda Pro | [cellulite treatment in Singapore](https://ineternityclinic.com/cellulite-treatment-singapore/) | | Soft muscle tone despite a stable weight | Z Sculpt | [Z Sculpt](https://ineternityclinic.com/z-sculpt-body-contouring-singapore/) | | Red or white stripes on the skin | Fractional laser or RF microneedling, by stage | [stretch mark treatment in Singapore](https://ineternityclinic.com/stretch-mark-treatment-singapore/) | | Dark underarms or heavy sweating | Treatment by cause | [underarm whitening](https://ineternityclinic.com/underarm-treatment-singapore/), [underarm sweating treatment](https://ineternityclinic.com/underarm-sweating-treatment-singapore/) | | Wanting to lose weight overall | Weight management first; contouring afterwards for set areas | [weight loss vs body contouring](https://ineternityclinic.com/blog/weight-loss-body-contouring-singapore-guide/) | *How to choose a body treatment page. A starting point only: fat, skin and muscle are assessed in person, and many plans combine them.* A tummy after pregnancy, for example, can have all of these at once: a fat pocket, loose skin, separated muscles and stretch marks. The plan treats them in an order that makes sense, and anything that needs a surgical or medical opinion is said plainly. Results build over weeks and vary between people.

Questions ## Frequently asked questions **What is the difference between body contouring and weight loss?** Weight loss reduces fat across the whole body; body contouring reshapes set areas such as the flanks, abdomen or thighs. Contouring suits people near a stable weight with pockets that do not respond to diet and exercise. [Weight loss vs body contouring](https://ineternityclinic.com/blog/weight-loss-body-contouring-singapore-guide/) explains how the two work together. **Which suits me: the 4K Body Lift, Onda Pro or Z Sculpt?** It depends on the tissue. The 4K Body Lift and Onda Pro act on local fat and loose skin; Onda Pro is also used for cellulite; Z Sculpt builds muscle tone. Many plans combine them. [Body contouring in Singapore](https://ineternityclinic.com/4k-body-lift/) compares the three, and the choice is made after Dr Sin Yong assesses you. **Does IN Eternity Clinic offer fat freezing?** No. Fat freezing (cryolipolysis) is explained and compared in the guides on this page, but it is not offered at IN Eternity Clinic. The body options used here are Onda Pro, the 4K Body Lift and Z Sculpt, and Dr Sin Yong will still tell you if another approach suits you better. **How many sessions do body treatments need, and when do results show?** It varies by treatment and area. Z Sculpt is usually a course of four to six sessions; the 4K Body Lift is typically one to three sessions about six weeks apart, with a review at six weeks. Change from fat and skin treatments builds over weeks, and results vary between people. **Can stretch marks be removed?** Stretch marks can be softened but not erased. Red, early marks usually respond better than white, mature ones. Treatment is a course of fractional laser or RF microneedling, weeks apart, with careful settings in Asian skin. [Stretch mark treatment in Singapore](https://ineternityclinic.com/stretch-mark-treatment-singapore/) explains each stage. **What helps underarm darkening and heavy sweating?** They are different problems. Dark underarms are usually post-inflammatory, from friction and shaving, and are treated by cause, sometimes with pico laser. Heavy sweating is graded first, then treated with injections or other options. The two underarm pages explain each. **Other topic hubs:** [Pigmentation hub](https://ineternityclinic.com/treatments/pigmentation/) · [Acne and scars hub](https://ineternityclinic.com/treatments/acne-and-scars/) · [Lifting and tightening hub](https://ineternityclinic.com/treatments/lifting-and-tightening/) · [Injectables hub](https://ineternityclinic.com/treatments/injectables/) · [Hair and skin quality hub](https://ineternityclinic.com/treatments/hair-and-skin-quality/) ## Book an assessment IN Eternity Clinic, 9 Scotts Road, #12-01 Pacific Plaza, Singapore 228210.
