Laser-assisited liposuction (SmartLipo) is appropriate for both reducing volume and skin tightening, to a degree. Where traditional tumescent liposuction might leave skin a little looser in areas such as the inner thighs, upper arms or abdomen when stretch marks are present, SmartLipo promotes skin tightening by thermal contraction as well as collagen formation. It will not be a substitute for an armlift, thighlift or abdominoplasty if the skin is already significantly lax. Your board certified plastic surgeon can guide you to the most appropriate procedure for your specific needs.Best, Scott A. Brenman, M.D., F.A.C.S.Plastic & Reconstructive Surgery
