An apparatus and method for simultaneously applying a compressive and a reciprocating force to underlying adipose cells from a location external to a patient's skin to rupture or otherwise remove the adipose cells within a subcutaneous tissue region. The adipose cells are ruptured through the mechanical application of compression and shearing forces. The patient's body then re-absorbs and expels the ruptured cells. This eliminates the need for invasive liposuction and the trauma associated with invasive liposuction. Various mechanical devices may be employed to impart the compressive and shearing forces.
