Hello! I'd like to invite Dr. Shujie Wang to answer your questions. Facial liposuction needle has no official national approval. We don't need liposuction needles in our hospital. Facial liposuction does not require surgery. Facial obesity is caused by many reasons. If your facial obesity is caused by subcutaneous fat hypertrophy, it can be solved by facial fat suction. The swelling was basically relieved 7 days after operation. We are the Plastic Surgery Hospital of China Academy of Medical Sciences and Peking Union Medical College (located at No.33 Badachu Road, Shijingshan District, Beijing), the only third-class first-class plastic surgery hospital directly under the Ministry of Health in China, and the largest plastic surgery hospital in Asia, enjoying the highest academic status in the plastic surgery field in China. The hospital is equipped with comfortable medical environment, first-class medical technology and all-round medical services. In order to meet the multi-level service demand, the hospital has also set up a special medical department (VIP ward). Welcome to our hospital and wish you a happy visit! Thank you for your inquiry!
