Hello, this is Dr. Han Ji-young of ACRO Korean Medicine Clinic.
“My weight is normal, but it feels like all the fat goes straight to my belly.”
Quite a few people come to us whose weight is perfectly fine by BMI, yet fat gathers on the abdomen in particular, so their clothes just don’t fit well.
Today, looking at same-day before-and-after photos of a patient with this “abdomen-dominant” body type who had ONDA Lifting,
I’ll go over which changes show up first right after treatment.
What Was the Patient’s Situation?
- Fat was thickly settled across the whole abdomen, from the upper to the lower belly, centered on the navel;
- from the side, the lower belly pushed forward, creating a line where fat rested over the waistband;
- and stretch marks (striae — marks formed in the dermis when skin stretches over a short period) were seen on the skin of the flanks and lower belly.
Treatment Plan
- 26/10/27: ONDA Lifting / entire abdomen (upper to lower belly, including the flanks)
- Energy: 180W / 150,000J / about 20 minutes
Before-and-After Changes (same day, 26/10/27)

Front view: Before treatment, the lower belly below the navel protruded in a rounded shape, and a slight fold of fat was visible just above the waistband.
Right after treatment, the rounded protrusion of the lower belly was reduced, and the surface from below the navel to the waistband looked noticeably flatter,
with the waistline on both sides also flowing more smoothly from top to bottom.
The texture of the skin surface also looks a little tighter and smoother than before treatment.

Side view: The difference is even easier to see in the side photos.
Before treatment, the lower part of the belly bulged forward and rested over the waistband; after treatment, the protrusion of the lower belly became gentler, and the side line from below the solar plexus to the waistband runs down closer to a straight line.
You can also see that the skin of the lower belly, where the stretch marks were, looks less loose.
How Should Same-Day Changes Be Understood?
- Right after treatment: a tightening effect as heat stimulation causes collagen fibers to contract and the skin to tighten
- 2–6 weeks: volume reduction progresses as heat-damaged fat cells are gradually cleared
- 2–12 weeks: elasticity and contour improve gradually as new collagen forms (peaking at around 3 months)
Treatment Points
First, even at a normal weight, you need to look at “where the fat has built up.”
Even if your weight or BMI is normal, concerns about body shape can easily arise when fat is concentrated on the abdomen. In particular, when weight goes up over a short period, fat often builds up on the abdomen first, so overall weight loss alone may not refine the belly line as much as hoped.
Second, we plan overall management and local treatment separately.
For this patient, we divided the roles: herbal diet medicine for appetite control and overall weight management, and ONDA Lifting for the abdominal contour. If lifestyle patterns and appetite stay the same, fat can build up again even in a treated area, so pursuing both together is better for maintaining the results.
Third, for the abdomen, we use enough energy to match the thickness of the fat layer.
Compared with the face, the abdomen has a thicker fat layer and a larger area, so if the power and total energy are insufficient, the change you feel may be weak. In this case, 180W and 150,000 J were distributed evenly across the whole abdomen. Skin with stretch marks has a thinner dermis, so it is also important to monitor the skin’s response during treatment.
Summary
If your weight is normal but only your belly protrudes, it is likely to be an issue of “fat distribution” rather than weight. As in this case, contour changes from tightening can appear first even on the day of treatment, followed by fat reduction and improved elasticity over the following weeks. However, the degree and speed of change can differ from person to person depending on fat-layer thickness, skin elasticity, eating habits, and lifestyle.
If your weight is basically fine but your belly fat just won’t budge, we will design a treatment strategy suited to your body type and fat distribution together during your consultation.
