The present invention provides an apparatus and method of body contouring and skin conditioning. The apparatus (10) treats cellulite and the like by producing vibrations in the subcutaneous layers of fat. A cup (18) of handpiece (16) is placed against the skin to create a chamber (60). A vacuum source (160) and compressor (162), which are in communication with chamber (60), are then controlled to produce an oscillating pressure within the chamber (60). This vibration of the skin surface is transferred through the dermal layers thereby influencing fluid retention and cellulite build up.
