The black part below the roller is a solar panel, so the massager does not need to be charged. It is equipped with a light plate with pattern energy, which generates micro-current by absorbing solar energy. This micro-current can be combined with the human body's current to improve cell metabolism and detoxification, so the skin looks shiny and firmer.

The roller beauty massager consists of two circular massage beads and a handle, which can help to eliminate the edema problem on the face.
