Photopneumatic technology illustrated

The handpiece is applied to the skin surface on the area to be treated, making sure there is a good seal between the tip and the skin surface. (Fig. 1A). Negative pressure is applied automatically, and the skin is then lifted up toward the irradiation port reducing the distance between the skin surface and the target dermal tissue (Fig. 1B), followed by irradiation from the flash lamp (Fig. 1C). The vacuum is released and the skin surface then automatically returns to normal after the irradiation (Fig. 1D).
