At a glance

Body Ultherapy firms lax skin. It does not reduce fat, body weight or the structure of cellulite.
A session takes 60-120 minutes and daily activities can resume right after it.
Ultherapy PRIME holds a U.S. FDA indication for skin firmness on the front and back of the arms and on the abdomen.

What is Body Ultherapy?

Body Ultherapy is ultrasound lifting for lax skin on the arms, abdomen and thighs, done with the same device and 1.5, 3.0 and 4.5 mm transducers used on the face. The combination is chosen from the skin and subcutaneous fat thickness of each area, which is why a body plan is not a copy of a facial one.

The front and back of the arms and the abdomen are the areas with a U.S. FDA indication for Ultherapy PRIME, and RESUM builds its recommendations around them. Inner thighs have thin skin, so 1.5 and 3.0 mm carry most of the work there and 4.5 mm is used sparingly.

How long does Body Ultherapy take?

Body Ultherapy takes 60-120 minutes, longer than a facial session because the areas are wide. The session can be paced in stages while we check how you are feeling, so avoid booking anything tight straight after it. Daily activities can resume the same day.

Session	60-120 minutes
Numbing	Numbing cream; IV sedation available
Back to daily activities	Right after the session
How long it lasts	About 12 months

What can Body Ultherapy not do?

Body Ultherapy does not remove fat, lower body weight or change the structure of cellulite. For cellulite, a smoother surface texture is the realistic limit. If you need less fat volume, another treatment or surgery is the better route, and an abdomen left lax after childbirth that skin firming alone cannot correct may call for abdominoplasty. Dr. Jin-Young Kim says which applies during the consultation.

Purpose & suitability

The skin on your arms or abdomen has loosened after childbirth, weight change or with age.

Your aim is firmer skin, not weight loss.

You prefer treatment focused on areas with an established indication: the front and back of the arms and the abdomen.

You want to work on body contour firmness gradually and without surgery.

You would like a frank account of expectations and limits before you decide.

Treatment process

Goal check. Dr. Jin-Young Kim examines skin firmness on the arms, abdomen or thighs and tells you whether firming matches your goal or whether a fat or weight treatment is what you need.
Plan by thickness. Depth, energy and line spacing follow the skin and fat thickness of each area, and the treatment range is drawn around areas with an established indication.
Wide-area treatment. Tissue thickness is viewed on DeepSEE real-time imaging and the area is covered evenly, line by line.
Aftercare briefing. The skin is soothed, then we explain care for tenderness and swelling and when firmness is likely to change.

Time & recovery

Tenderness or mild swelling can be noticeable for 1-2 weeks, and a large area may not recover at one pace throughout.

For a few days, skip saunas, strenuous exercise and strong massage on the treated area, and keep the skin well moisturised. If your trip includes hiking, a gym session or a spa day, place it before the treatment.

Firmness builds slowly over 2-3 months, so most of the change arrives after you are home.

Limitations & precautions

Outside the arms and abdomen, whether Body Ultherapy applies and how far it can go is explained area by area in the consultation.

Temporary swelling, tightness, slight bruising and irritation can occur and settle within 1-2 weeks. Hyperpigmentation or temporary irritation has been reported in rare cases.

Results build gradually and differ from person to person.

Frequently asked questions

Can I have Body Ultherapy on a short stay in Seoul?

Yes, Body Ultherapy takes 60-120 minutes and you can return to daily activities right after it. Allow for tenderness or mild swelling for 1-2 weeks, and avoid saunas, strenuous exercise and strong massage on the treated area for a few days.

Can it replace liposuction or a tummy tuck?

No, Body Ultherapy is not a substitute for liposuction or weight-loss surgery. It firms skin and leaves fat volume unchanged. When an abdomen that became lax after childbirth cannot be corrected by firming alone, RESUM also discusses surgical options such as abdominoplasty.

Does Body Ultherapy treat cellulite?

Not the cellulite itself. Body Ultherapy does not change the structure of cellulite, and a refined surface texture through collagen stimulation is as far as it can reasonably go.

Which body areas can be treated?

The front and back of the arms and the abdomen are the main areas, because Ultherapy PRIME has a U.S. FDA indication for skin firmness there. Inner thighs are also treated, with 4.5 mm used conservatively. For other areas, Dr. Jin-Young Kim explains in the consultation whether treatment applies.

When will my skin feel firmer after I go home?

Firmness after Body Ultherapy usually builds over 2-3 months, with new collagen forming over 2-6 months. Some change is visible right after the session. The timing differs between individuals, so RESUM does not give a fixed date, and the overview figure for how long it lasts is about 12 months.
