Through the low frequency vibration of ion, cavitation reaches the ideal effect for cellulite reduction. The vibration of ion wave would produce a strong power through positive and negative alternation, which brings different pressure to the cell membranes internally and externally. When cell membrane cannot endure the pressure, it will explode, break into liquid and get out of human body by metabolism. The quantity off at cell is reduced. The ideal effects for cellulite reduction will be achieved and the fat cell metabolism also will be improved.
