Optical fiber fat dissolving method is very safe. Only local anesthetics are used during the operation, and swelling fluid is not injected, so there will be no bleeding during the operation. After operation, the shortcomings such as excessive liposuction and exudation, repeated dressing change and cotton pad replacement, obvious swelling, obvious scar and long rest time were eliminated. Moreover, optical fiber lipolysis will not damage blood vessels and nerves, there will be no adverse complications, and there will be no unevenness caused by negative pressure liposuction. This is a very safe technology, although it is safe to use.
