The Inner Ball Roller Endospheres Therapy Principle

The inner ball roller machine is a non-invasive mechanical compression micro-vibration + infrared treatment. The principle is to generate compression micro-vibration by rolling the silicone ball along the 360° rotation of the roller. As the ball rotates and exerts pressure on the skin, it produces a “pulsation compression” effect, which realizes the reciprocating motion of continuous pushing, pulling, and kneading, and the tissue will experience some pressure. And lifting action, will not squeeze or damage the skin, its principle is to release infrared rays while pressure is applied to the tissues to stretch the cells to naturally and deeply stimulate cell activity, blood flow, and oxygenation, and the fat deposits are pressurized and thus loosened for final decomposition, Reduces cellulite and removes cellulite; also exerts pressure on deep muscle groups to fully soften and stretch, thereby reducing muscle stiffness and soreness, accelerating metabolism, eliminating stagnation and fluid accumulation, conditioning tissues and re-tightening skin tissues, reshaping your body. The Inner ball roller endospheres therapy can also stimulate fibroblasts, increase the production of collagen and elastin, increase blood flow, and increase oxygen. As a result, wrinkles are smoothed, puffiness and bags under the eyes are reduced, and the skin is rejuvenated and tightened. This technology has been clinically proven to help tone muscles and sculpt the body and face to rejuvenate. It can also help redesign and tighten the chest.

Real-time Temperature Control

Preset the target temperature before treatment, always control the temperature at the set temperature, and monitor and display it in real-time. Adjustable 42-45°C constant temperature. The subcutaneous tissue reaches 65-70°C, precisely melting fat.

Vacuum Negative Pressure

Through the rotation movement and contact with the vacuum negative pressure at the same time, it stimulates the lymph and blood circulation, accelerates the elimination of edema, eliminates lymphatic obstruction, and enhances blood flow to the tissue.

180°rotation and twisting

180°alternating rotation and twisting stimulates the metabolism in of cells, reduces edema, expels toxins, and relieves muscle spasms and pain syndromes.

LED red and blue double light

LED red and blue dual light irradiates the skin, which can increase the temperature of fat, stimulate the activity of deep cells, promote blood circulation and decompose triglyceride more efficiently, and help it to be excreted.
