What this treatment is
The 4K Body Lift uses radiofrequency (RF) energy on the Secret DUO platform, developed by ilooda, which is now part of CLASSYS. Fine insulated needles carry the energy into point zones under the skin.
It uses RF only. There is no EMS, so it does not work on muscle. Depth is chosen for each person and does not follow a default.
How the 4K Body Lift protocol in Singapore works
How it differs from other body options
| Option | Works on | Key limit |
|---|---|---|
| 4K Body Lift | Compact fat and the skin over it, using RF | Not for large volumes or marked loose skin |
| Z Sculpt | Muscle tone and the fat layer over the muscle, using electromagnetic stimulation | Does not tighten loose skin |
| Time Freeze Laser LCLR® Bodylift | Laxity over a thin layer of fat, using laser | Reaches only superficial fat |
| Vertical Figure Lift | Skin that has lost recoil, with little fat, using monopolar RF on Volnewmer | Does not reduce fat; hanging skin is referred |
| Liposuction | Surgical fat removal | Not performed here, referred out |
4K Body Lift or another body protocol: the pinch test
Dr Sin Yong starts the body examination with a pinch. A firm pocket that gathers between the fingers, under skin that springs back, is fat, and that is where the 4K Body Lift is aimed. Skin that lifts away as a loose fold and settles back slowly has lost recoil, which is a skin question for the Vertical Figure Lift. Loose skin over a thin layer of fat may suit the Time Freeze Laser LCLR® Bodylift.
Many people have more than one finding, so the order matters. Taking fat away from under skin that no longer recoils can leave the outline looking looser, so the skin is assessed before any fat-directed step is planned. Skin that hangs as an apron is referred for a surgical opinion.
Areas that may be treated
| Area | Typical concern |
|---|---|
| Tummy and abdomen | Compact fat that remains near usual weight |
| Waist and flanks | Localised fullness at the sides |
| Inner and outer thighs | Resistant fat, with mild looseness over it |
| Arms | Compact fat on the upper arm |
| Bra-line back | Fat around the bra line |
| Knees and under the chin | Small zones, assessed individually |
Who it may suit
It is aimed at people close to their usual weight who have a localised concern. Fat should feel compact and resistant, and any skin looseness should be mild. It also suits those who want to avoid surgery and can accept gradual change. If your main goal is muscle tone, Z Sculpt works on a different target. If you want a wider view, read about belly fat reduction or fat freezing, and ask which fits your body. A useful test is your own history. If your weight is steady and one area has stayed the same despite exercise, the concern may be local. If your weight has risen, the plan usually starts elsewhere. Dr Sin Yong performs the treatment himself and will tell you if he does not advise it.
Who should wait or avoid it
Pregnancy and breastfeeding. Recent childbirth, until the area has healed and abdominal muscle separation has been checked. Active infection, open wounds, or eczema or other skin conditions in the zone.
A pacemaker or other implanted electronic device. Metal implants or threads in or near the area. Weight well above your usual, or a goal of weight loss.
Bleeding tendency or blood-thinning medicine. Keloid tendency or poor healing. Poorly controlled diabetes or other conditions that slow healing.
What it cannot do
It cannot remove large volumes of fat. It cannot correct marked loose skin, including skin left after major weight loss. Those cases are referred to a plastic surgery specialist. It does not replace liposuction or weight management, and it is not sold as a way to lose weight. The change, if it comes, is local and gradual. How much you see depends on your fat, your skin and your healing, so no result can be promised. Think of it as a treatment for a defined area, and not for the whole body. A person with a large amount of fat or a lot of loose skin is likely to be disappointed, and a different plan will serve them more honestly.
Risks and side effects
Redness, warmth, swelling, tenderness and fine pinpoint marks from the microneedles. Bruising is possible and typically lasts one to two weeks.
Temporary numbness or firmness, small raised bumps along the treatment pattern, and darkening after inflammation. Darkening is more likely in Fitzpatrick III to V skin and with sun exposure.
Burn, blister, scarring, infection or an uneven contour. Please tell the clinic early if anything worries you. See complication care.
Sessions, recovery and aftercare
The protocol is planned for you and is not sold as a fixed course. Where more than one session is needed, sessions are about 6 weeks apart, and the number is not set in advance. There is no incision or general anaesthetic. Keep the area clean and moisturised. Avoid heat, saunas and strenuous exercise on the first evening. Use sun protection on exposed zones. Arnica may be suggested if bruising appears. Each zone is looked at again before any further treatment is timed. Arrange your first evening so that you can rest the area. Fine pinpoint marks come from the microneedles. If bruising appears, it may take one to two weeks to clear, so please allow for that before events. Sun protection matters because darkening after inflammation is more likely in medium to darker skin.
Questions to ask before you decide
Compact, resistant fat is the main target. Ask how your area was assessed, and what that means for your plan.
Mild looseness may be in scope. Marked looseness is not. Ask where you sit.
Weight management, surgery or a different device may fit better. A consultation can end with no treatment advised.
Implants, threads, medicines and recent childbirth all change the plan. Bring your records.
Each zone is reassessed at about 6 weeks. Ask what you should look for at home in the meantime.
How the fee is set
The fee depends on the areas and number of zones, the passes needed, the Secret DUO consumables used, and whether another treatment is combined. It is set after assessment and not as a fixed course. You receive a written quote at consultation. Read how we quote for what a quote covers. Because each zone is reassessed, you only decide on further treatment after seeing how the first session went. The consultation also decides whether treatment should go ahead at all. Please declare implants, threads, medicines, and recent pregnancy before you attend, because any of these can change the plan or the quote.
