Ultrasound and laser-ultrasound for face and body An ultrasound handpiece has been designed, which is combined with red-coloured phototherapy semiconductors and an optical source of light with laser. The soft lasers have triple biological effect: bio-stimulation of the skin cells, pain-relieving, and anti-inflammatory effect. The bio-stimulation with laser results in faster replacing of the cells of the epidermis by shortening the duration of the cell-cycle.
