The inner ball roller device is a non-invasive mechanical compression micro-vibration treatment device. The principle is that the silica gel ball rotates 360° along the roller to generate compression micro-vibration. When the ball rotates and exerts pressure on the skin, the effect of \"pulsating compression\" is generated to achieve continuous push-pull kneading and reciprocating motion. The tissue experiences a certain pressure and lifting effect without squeezing or damaging the skin. This pressure stretches the cells, naturally and deeply stimulating cell activity, blood flow, and oxygenation. Fat deposits are pressurized to loosen and eventually decompose, reducing cellulite and eliminating it.
