Technical Field

Background

The traditional skin grinding adopts a treatment method of grinding rough skin or color spots by using sand paper, a grinding wheel, a steel wheel grinding head or microcrystals to level the skin and eliminate pathological changes. But the grinding technology is rough, the precision is not easy to control, and the possibility of scar after operation is increased.

Conventional lasers, such as carbon dioxide or erbium lasers, which vaporize tissue for treatment, are typically applied perpendicular to the skin. Because the texture of the skin is different among different people and even the same person is different at different positions, the damage depth of the laser with the same energy after the laser acts on the skin is different, the treatment depth is not easy to be accurately controlled, and the scar formation is often caused by the over-deep action of the laser.
