hello pureskinjunkie In general, the complications are the same that can occur with traditional or any other liposuction including: infection, bleeding, swelling, discoloration. However, problems such as rippling and waviness of the skin seem to be less. Theoretical problems specific to Vaser ultrasound can include burns at the skin edge where the cannula is inserted but, an experienced board certified surgeon will use skin guards to protect the area, and like all of these potential problems, they should rarely occur. Vaser, like other liposuction procedures is a generally safe, commonly performed and well liked by my patients, providing excellent long-term results. #options #lipo
