Dermatology ClinicThermage FLX Body in Busan, Korea Radiofrequency tightening for loose skin on the stomach, arms, thighs and knees
Thermage FLX is best known for the face, but the same monopolar RF can firm crepey or loose skin on the body. At JRYN Seomyeon the doctor sizes the shot count to the area and confirms the total before you agree .
Does Thermage FLX work on the body?
Yes, for the right kind of skin. Thermage FLX heats the deep dermis with radiofrequency energy, which tightens existing collagen and prompts new collagen to form. On the body it suits mild to moderate looseness, such as crepey skin above the knees, a soft lower stomach after weight loss or pregnancy, or loose skin on the upper arms. It firms skin; it does not remove fat or excess folds of skin.
At JRYN Seomyeon, Thermage FLX is listed at ₩1,200,000 for 300 shots , ₩1,790,000 for 600 and ₩2,690,000 for 900. Body areas are larger than the face, so Dr. Jin confirms how many shots your area needs , and the total, at consultation.

Who it suits
- Skin on your stomach looks loose after weight loss or pregnancy
- Skin above your knees or on your upper arms has gone crepey
- Your weight is stable and you want firmer skin, not fat loss

Which body areas can Thermage FLX treat?
Common areas are the lower abdomen, upper arms, inner thighs, the skin above the knees, the flanks and the buttocks. The skin needs to be loose rather than heavily folded. The doctor checks this in person.
Will Thermage FLX Body get rid of fat?
No. It tightens skin by remodeling collagen and is not a fat-reduction treatment. If fat is the main concern, Body Onda or another contouring option may suit you better, and some people combine the two.
Is there downtime?
Downtime is minimal. The area may be red, warm or a little tender for a day or two. Most people return to normal activities, including flying, straight away.
When will I see results and how long do they last?
Some people notice a slight change early, but firming mainly develops over 2 to 6 months as collagen remodels. How long it lasts depends on age, skin and weight stability. Some people repeat treatment after about a year.
Does it hurt?
You feel short pulses of deep heat, balanced by the device cooling the skin. The doctor adjusts the energy to your comfort. Numbing options can be discussed at consultation.
Can I have it after pregnancy?
Many people consider it once they have finished breastfeeding and their weight is stable. It is not done during pregnancy. The doctor will check the abdominal skin and any separation of the muscles, which RF cannot correct.
