Working Principle: Velashape machine adopts "Three-dimensional Negative Pressure Mechanical Stimulation" technology, which is a non-invasive vacuum negative pressure massage therapy. The principle is that through the bidirectional electric roller combined with vacuum negative pressure of the nursing head device, and the electric flap combined with vacuumnegative pressure of the nursing head device, the skin tissue to carry 4 out rolling, suction, kneading, clamping, bouncing and other mechanical aerobic exercise, skin tissue repeated rhythmic deep massage and mechanical stimulation. Continuity can be deeper into the connective tissue and adipose tissue, subcutaneous tissue, lymphcirculation system and blood circulation system, and thus to be skin organization exerts special physical stimulation and the actuating effect, make skin tissue under the oppression and wrinkled, and under the effect of positive and negative pressure produces delicate mechanical stimulation to deep skin tis
