The site of liposuction is mainly in the superficial fat area between subcutaneous and muscle upper layer. However, human nerves and blood vessels are distributed under facial muscles, and the instruments are relatively blunt. Facial liposuction will not cause permanent damage to blood vessels and nerves, and generally will not affect facial expression.

However, it is suggested that we must choose a regular and qualified hospital and a professional, experienced and skilled doctor for surgery, which can effectively avoid the corresponding surgical risks.
