When the lower abdomen still feels loose even after losing weight, Body Onda lifting often comes to mind.

This can happen when exercise helps you lose weight, but the skin looks wrinkled and sagging.

These changes may be a matter of elasticity rather than fat.

This is because, as stretched abdominal fat decreases, the skin may not be able to keep up with the change and can remain loose.

This is also why you may feel dissatisfied when viewing your side profile in the mirror.

There are areas that cannot be addressed simply by losing more weight.

The cause of sagging that remains after weight loss

A sagging lower abdomen is not simply caused by the fact that all the fat has not been lost. When the skin stretches significantly due to pregnancy or changes in body weight, the collagen and elastic fibers within it can become damaged, preventing it from tightening back to the same extent as it contracts. Skin naturally has elasticity that allows it to stretch and contract. However, this recovery capacity has limits.

When rapid changes occur repeatedly or as we age, the skin’s ability to return to its original position weakens. That is why, even after losing weight, only the skin may remain like an empty balloon, appearing wrinkled. Building muscle through abdominal exercises does not itself tighten the sagging area.

This is because muscle fills the inside, while the lost elasticity must recover separately in the dermal layer. This looseness tends to be more noticeable, especially after childbirth or significant weight loss over a short period. To make the area that has lost volume firm again, an approach that restores the supportive strength within the skin is needed.

How heat is delivered to the deeper layers

Body Onda lifting delivers heat to the deeper layers within the skin using ultra-high-frequency microwaves. As heat accumulates in the dermis and the underlying fat layer, it stimulates loose collagen and induces both contraction and renewal. In other words, it helps warm the stretched skin from within so that it can tighten.

The key is that the heat must reach a sufficient depth. Because abdominal skin is relatively thick, surface care alone may have difficulty delivering stimulation to the dermal layer. Body Onda works together with cooling that cools the epidermis, protecting the surface while concentrating heat in the deeper layers. The energy is adjusted in joules rather than shots, and a larger treatment area generally requires planning for a greater number of joules. The typical number of joules selected according to the improvement goal is as follows.

| Focused treatment of a localized area: approximately 60,000 joulesCentral abdominal area focus: approximately 80,000 joulesOverall abdominal elasticity improvement: approximately 100,000 joules |

The required number of joules and sessions varies from person to person depending on skin thickness and the degree of sagging.

Elasticity that gradually tightens and returns

Because collagen renewal takes time, changes do not become apparent immediately after the procedure but gradually emerge over several weeks. At first, the skin may feel smoother, and with repeated sessions, you may notice that the previously loose lower abdomen feels firmer. As the wrinkled surface becomes more even, the way clothes fit may also change.

Because it takes time for elasticity to build, changes that have settled in tend to last relatively long.

Some people first notice that clothes that did not fit last year have become more comfortable. However, if significant weight changes occur again, the skin may stretch once more, so weight management after the procedure can affect the results. For a few days immediately after the procedure, there may be a slight sensation of warmth or heaviness, and the contour stabilizes after this period. Recovery speed and the number of sessions needed vary depending on skin condition and age.

Lower abdominal sagging is often more a matter of elasticity than the amount of fat. Even after losing weight, a sagging feeling can remain if stretched skin does not tighten along with the change. Body Onda lifting works by stimulating the loose skin in the deeper layers to help restore elasticity.

If you have been dissatisfied with areas that could not be improved through exercise and dieting, the issue may have been elasticity rather than fat. Even when sagging looks similar, the approach differs depending on whether the cause is fat or elasticity. It may be best to first determine which of these is closer to the cause of your lower abdominal sagging.
