Vacuum supersonic fat-explosion machine can improve tissue metabolism, repel the cellulite, tighten the skin, strengthen the skin elasticity and so on. Its effect will last for a long time. At the meanwhile, it can enhance the muscle elasticity and improve the cell metabolism. • Supersonic wave creates an effect like internal explosion. It means that the expansion and compression of wave produce a lot of tiny space inside the liquid. The liquid and vapor exist in these tiny space.
