What's the difference between dull needle thigh ring suction and liposuction?

Thigh liposuction: doctors inject an appropriate amount of expansion liquid into the parts of the body with more fat, and then put blunt needles into the parts of the body through negative pressure to draw out the excess fat cells, so as to achieve the purpose of local rapid slimming and shape, and then sew the wound after the liposuction.

Thigh ring suction: It is a technical upgrade on the traditional liposuction. It adopts the minimally invasive liposuction operation combining negative pressure liposuction and ultrasonic liposuction to carry out alternating deep and shallow layers of uniform liposuction, which can carry out multiple parts of liposuction. The incision after liposuction is small and the effect is obvious.
