Hello, radiofrequency lipolysis is to emit high-frequency electric waves through electrodes to achieve the purpose of ablating and treating regional fat. Similar to laser lipolysis, laser lipolysis can also tighten the skin, and the skin tightening effect in the treatment area can last for 2-6 months, but it is only suitable for the back with less fat and has little effect on large area of fat. You can consult a beauty medical institution with relevant technology. I hope my answer can help you.
