Hello.

I’m Wi Young-jin from Beauty’s Doctor.

It is common for the abdomen to remain loose and saggy even after losing the weight gained during pregnancy.

Even after finally returning to their pre-pregnancy weight, many people experience significant stress when they look in the mirror and see abdominal skin that has lost its elasticity and become wrinkled.

There are also many accounts from people who search online and diligently start home workouts or exercise, only to find that the area does not seem to slim down separately.

This is not simply a matter of willpower. It is because treatments and exercise serve entirely different roles.

I’ll briefly and clearly organize the key factors that can easily be confusing for those who are first exploring ways to manage abdominal elasticity.

How Devices Used for Abdominal Treatments Work

Medical treatments frequently used in dermatology to restore abdominal elasticity are broadly divided into three categories: InMode, which combines RF radiofrequency with vacuum suction; Thermage Body, which heats a broad area using RF radiofrequency; and devices in the HIFU, or focused ultrasound, category.

InMode is a medical device that uses radiofrequency energy and vacuum suction technology.

By contrast, RF radiofrequency devices designed for the body deliver thermal energy throughout the broad dermal layer of the abdomen, inducing a tightening response in the loosened surface skin.

Finally, HIFU devices such as Ultherapy are used to deliver energy to layers much deeper than the skin’s surface.

Which device is suitable for you depends precisely on factors such as the thickness of your abdominal fat and the degree of skin laxity, which vary from person to person.

Medical Treatments Also Have Clear Limitations

The treatment method that can be applied may vary depending on the condition of the abdomen.

If stretch marks that developed during pregnancy remain deeply adhered, or if the skin is severely sagging like a deflated balloon with a curtain-like appearance, surgical treatment may be considered in some cases rather than a procedure.

Therefore, during your initial consultation, it is helpful to clearly and realistically determine first whether your abdominal condition falls within the range that can be corrected with a procedure. This makes it much easier to manage your expectations afterward.

The treatment plan may vary depending on your individual condition. For safety, you should carefully review with your doctor the total number of treatment sessions and cumulative cost appropriate for the degree of sagging.

This post summarizes general information about abdominal changes after childbirth.

For the safest treatment plan tailored to the volume of your abdominal subcutaneous fat and the degree of loss of skin elasticity, you should discuss the options in depth with a doctor who has examined and diagnosed your body in person.

Frequently Asked Questions (FAQ)

Q. Can this also be applied to stretch marks that developed after childbirth?

A. To be honest, the reddish or whitish stretch marks themselves are not the primary target of abdominal lifting laser treatments.

Whether treatment can be applied may vary depending on the condition of the skin.

[Post-Treatment Precautions and Side Effects]

After RF radiofrequency and HIFU ultrasound treatments to improve abdominal elasticity, temporary redness, swelling, throbbing, bruising, or tenderness may occur depending on the individual’s constitution and skin condition.

Body treatments in particular involve accumulating a relatively high total amount of energy over a broad area. If the device tip does not make precise contact, there is a risk of burns to the epidermal layer, blister formation, or irritant-induced hyperpigmentation.

Temporary sensory changes caused by nerve stimulation during the procedure may also rarely occur. If your pain worsens after treatment or you notice unusual signs on the skin’s surface,

you must immediately visit a nearby medical institution that provides the treatment and receive appropriate medical attention.

Thank you for reading this long post.
