VASER liposuction uses ultrasound energy to loosen fat cells before they are removed, so the surrounding nerves, blood vessels and connective tissue are largely left undisturbed. That is what allows a clinician to sculpt with precision rather than simply reduce volume, and it is why bruising and downtime are typically lower than with traditional liposuction.
At our Oxford Street clinic in central London every procedure is performed under local anaesthetic as a walk in, walk out day case. There is no general anaesthetic and no overnight stay: you arrive in the morning, the treatment is completed the same day, and you go home with your compression garment fitted.
Most London patients are back at a desk within two to five days. The contour continues to settle over three to six months as swelling resolves and the skin retracts, which is why the plan often pairs VASER with NeoLift skin tightening or Green Laser sessions.
