Besides Photothermal Effects, Low-Level CO Laser Irradiation Can Potentiate Skin Microcirculation Through Photobiomodulation Mechanisms.

Improvement of microcirculation is one of the important mechanisms of low-level laser therapy (LLLT) to treat some diseases such as wound healing. Most previous studies have been carried out with multiple lasers other than the 10,600-nm CO laser. Recently, the CO laser has been used not only as a tool for excision of soft tissues but also for therapeutic applications.
