Body

Q: Do you use the same device on the abdomen, upper arms, and thighs?

Settings and scope may differ even when the same device is suitable. We plan for each area after checking skin thickness, fat volume, contours, and proximity to bones and nerves.

Q: How do Ultherapy Prime and XERF differ?

Ultherapy Prime uses ultrasound imaging to view tissue while delivering focused ultrasound to a target depth; XERF uses radiofrequency heat. Suitability depends on the area and your skin.

Q: Can Sofwave and EXION be used on stretch marks?

A device name alone is not enough to decide. Stretch marks vary in age, color, and depth; EXION methods depend on the available handpiece and mode. After consultation, we must confirm which methods are approved and applicable.

Q: Is it better to receive several device treatments at once?

Not always. We must consider the target depth and recovery time so that energy does not excessively overlap in the same tissue. It may be better to assess your response to one treatment first.

Q: Can I exercise right after treatment?

It depends on the device, intensity, and your response. If you feel warmth, tenderness, or swelling, postpone strenuous exercise and saunas; follow your post-treatment guidance for when to resume.

Q: How many body treatment sessions will I need?

The number and interval of sessions depend on the area, device, skin condition, and goals. We base the next step on your response after the first session rather than a fixed package.

Q: Can I receive NUVIJU on my abdomen or upper arms?

The currently confirmed approved indication in Korea is improvement of moderate to severe under-chin fat in adults. The clinician must check the approved scope and safety before explaining use on body areas or including it on the website.

The body's natural balance emerges when we support its own flow rather than force change.

Onsil's body program assesses each area's concerns and skin condition to find a natural sense of firmness and contour.

Skin thickness and
Personalized care considering fat distribution

The abdomen, upper arms, thighs, and buttocks may all appear to have “reduced firmness,” but their skin thickness, fat volume, direction of sagging, and movement differ. Onsil Clinic distinguishes whether skin firmness, localized contours, or stretch marks need attention after assessing your body and skin. We do not promise weight loss.

What makes Onsil Clinic's body program different?

Onsil Clinic's body program is personalized. We first distinguish sagging skin, reduced firmness, localized contour concerns, and stretch marks on the abdomen, upper arms, thighs, and buttocks, then select treatment as needed. Because ultrasound and radiofrequency devices differ in delivery and depth, we check skin thickness, fat distribution, the size of the concern area, and recovery time before planning a standalone or staged treatment.

Even in the same area, the approach changes depending on whether skin, the amount and distribution of fat, or muscles and body shape are the main factor.

Are these body concerns on your mind?

Even in the same area, the approach changes depending on whether skin, the amount and distribution of fat, or muscles and body shape are the main factor.

My weight has not changed much, but the skin on my abdomen feels loose.
When I raise my arms or wear sleeveless clothes, sagging and reduced firmness in my upper arms bother me.
The skin on my inner thighs or above my knees feels uneven and weak.
The boundary beneath my buttocks looks less defined and my skin seems less firm.
After childbirth or a change in weight, my skin feels stretched and I have stretch marks.
I would like to discuss nonsurgical options suited to my current condition before considering major surgery or a long recovery.

Changes in body contours involve more than fat alone

Changes in skin firmness and thickness

Age, UV exposure, pregnancy and childbirth, and repeated weight changes may affect how skin stretches and recovers. Thin and thick skin may respond differently to the same energy and need different precautions.
Amount and distribution of fat

Excess subcutaneous fat and loose skin may look similar but call for different approaches. Nonsurgical treatments do not replace weight loss or obesity treatment.
Muscles, posture, and lifestyle habits

Abdominal protrusion and the shape of the buttocks can also be affected by muscle tone, the pelvis, posture, and lifestyle. Medical procedures alone cannot change every aspect of body shape.
Age and color of stretch marks

The response of stretch marks to treatment may vary with when they formed, whether they are red or white, and their depth and extent. They require a separate assessment rather than the same approach used for ordinary skin tightening.

We assess your body before choosing a device

STEP 1

Identify the main concern area and goal

We identify which concerns you most—firmness, sagging, localized fat, skin texture, or stretch marks—and the degree of change you want.
STEP 2

Assess skin thickness and fat distribution

We check skin folding when standing and moving, left-right differences, fat distribution, sensitivity, and signs of previous treatments.
STEP 3

1:1 consultation with Medical Director Dr. Ji-seon Kim

We explain expected changes and limitations, and when exercise, weight management, or another treatment should come first.
STEP 4

Design treatment scope for each area

We consider contours and skin thickness on the abdomen, upper arms, thighs, and buttocks when planning treatment areas, areas to avoid, energy, and sequence.

The approach depends on your concern

01
When sagging and reduced firmness are the main concerns

We can assess whether a device treatment using ultrasound or radiofrequency energy at different skin depths is suitable.
02
When localized fat and contours are the main concern

We determine whether a skin-firming device is sufficient or a separate treatment to address localized fat is needed. For injections in body areas, we first confirm each product's approved uses and safety.
03
When texture and fine lines are the main concerns

If surface and dermal firmness matter more than widespread deep sagging, we consider a device that targets relatively shallow layers.
04
When stretch marks are the main concern

Stretch marks need a separate treatment plan based on their color, age, and skin sensitivity. We explain the potential and limits of treatment instead of treating them as the same goal as body lifting.

Body FAQ

Will body lifting help me lose weight?

No. Body lifting mainly addresses skin firmness, sagging, and localized contours; it does not replace overall weight loss. If weight and fat volume are the main concerns, consider lifestyle changes and relevant medical care together.
