Every body concern treated at IN Eternity Clinic on Orchard Road, sorted by cause. Dr Sin Yong first works out whether fat, skin laxity, muscle or the skin surface is driving what you see.
WhatsApp to Enquire →Key facts ↓Body contouring at IN Eternity Clinic starts by separating three problems: local fat, loose skin and skin-surface changes such as cellulite, stretch marks or pigment. Fat and laxity are treated with energy such as Onda Pro microwave or the 4K Body Lift; surface concerns use lasers and skin treatments. None replaces weight loss, or surgery for large skin excess.
Fat that stays put despite steady weight and exercise usually sits in the flanks, lower abdomen, inner thighs and upper arms. The stubborn fat page explains how it is told apart from visceral fat inside the abdomen, which no external treatment reaches, and from loose skin that only looks like fat.
For a pinchable layer, two energies are used at IN Eternity Clinic. Onda Pro delivers 2.45 GHz microwaves through DEKA’s Coolwaves system, heating the fat layer while the skin surface is cooled. The 4K Body Lift places radiofrequency heat through insulated microneedles at mapped depths, treating fat and the skin above it in one plan. Love handles have their own page, because the flank is where expectations most often need resetting.
IN Eternity Clinic does not offer fat freezing (cryolipolysis). If you are comparing, Onda vs fat freezing vs 4K Body Lift and fat freezing vs microwave body contouring set out the differences in mechanism, comfort and timing.

After pregnancy or weight loss the skin can stay lax even once the fat has gone. Loose skin after weight loss explains why: stretched dermis with fragmented collagen does not spring back on its own. Tightening energy can firm mild to moderate laxity; it cannot remove an apron of skin.
The sagging tummy page compares three approaches for the abdomen: Time Freeze Laser LCLR® body work, the VF Lift – Vertical Facelift protocol adapted for the body, and the 4K Body Lift. Svelte Touch combines radiofrequency and ultrasound for areas such as the arms, underarms and thighs, and non-surgical buttock contouring describes how reducing the flanks and lower back changes the shape of the buttock without surgery.
Where a large overhang remains, or the abdominal muscles have separated widely, a surgical opinion is the honest recommendation, and Dr Sin Yong will say so before any energy treatment is booked.
“If you can pinch it, energy may help. If it hangs, it is a skin problem, and sometimes a surgical one. I would rather tell you that first.”
Z Sculpt uses electromagnetic energy to make the abdominal, buttock or thigh muscles contract far more often in one session than a workout would. It adds firmness and tone, and is usually planned alongside fat or skin treatment rather than alone. The guide to muscle toning devices explains how these systems work in general.
Muscle can also be why an area looks bulky. A prominent trapezius gives a heavy shoulder line; shoulder slimming injections relax that muscle with a prescription medicine, a very different job from contouring fat.

Cellulite is structural: fibrous bands tether the skin while fat lobules push up between them. It is graded first, then each component is treated, with Onda Coolwaves used for the fat and connective-tissue element. Stretch marks respond differently depending on whether they are still red (striae rubrae) or have turned white (striae albae); the stretch marks condition page explains why white marks change more slowly.
Back and chest acne needs a diagnosis first, because a yeast-related folliculitis can look almost identical and needs different care. Under the arms, darkening, sweating and hair are separate issues: see underarm pigmentation and dark underarms, underarm sweating, and laser hair removal, which also reduces the shaving friction that keeps some underarms dark.
For background, the body sculpting guide and the weight loss and body contouring guide cover who is suited and realistic timelines. If your concern began after having a baby, the after-pregnancy hub covers timing and breastfeeding.
It depends on what is causing the shape. A pinchable layer of fat suits microwave or radiofrequency contouring, loose skin needs tightening energy, and widely separated abdominal muscles or a large overhang usually need a surgical opinion. Many tummies have more than one of these. Dr Sin Yong examines you standing and sitting, checks the muscle, and explains which parts treatment can change.
No. The clinic uses Onda Pro microwave energy and the 4K Body Lift radiofrequency protocol instead, both of which heat tissue rather than cool it. If you have had fat freezing elsewhere, mention it at consultation, including any area that became firmer or larger afterwards, because that changes how the area is assessed and treated.
No. These treatments reshape a defined area; they do not reduce body weight or the fat around internal organs. They suit people whose weight has been stable for some months. If your weight is still changing, the usual advice is to wait, because further loss or gain can alter both the result and the plan.
It varies with the area, the treatment and how your tissue responds. The 4K Body Lift is typically planned as one to three sessions about six weeks apart, while microwave and muscle-stimulation treatments are given as a short course. Change develops over weeks to months, so a review visit is booked before anything further is decided.
Cost depends on the number and size of the areas, which treatment is used, how many sessions are needed and whether skin and fat are both being treated. A written quote is given after Dr Sin Yong has examined the areas and agreed a plan with you. There is no obligation to book on the day.
Elective body treatments are deferred during pregnancy and usually while breastfeeding, and it is sensible to wait until your weight has settled after delivery. The pregnancy and breastfeeding safety page explains what is generally avoided and what may be considered after doctor review. Your own history, healing and feeding plans decide the timing.
