Traditionally, lasers have been utilized in many aspects ofmedicine, such as surgery, cancer treatment, and cosmeticapplications. The laser irradiation that was commonly usedin cosmetic surgery or cancer therapy is high intensity laserirradiation which can cut through the human bodies andburn the tissues. Except this well-known high intensity lasertherapy, there is another type of laser therapy, photobiomod-ulation (PBM), in which a low level/intensity/power laserirradiation or monochromatic light is used to modulatebiological functions without irreversible damage. It has beenwidely used to reduce pain and inflammation, acceleratewound healing and hair growth, prevent cell death andtissue damage, and improve blood circulation since theinvention of lasers in the 1960s. Currently, PBM is notonly used to treat diseases, but also used to promotehealth.

Despite many laboratory experiments and clinical trials,the cellular and molecular mechanisms of PBM continue tobe elusive. In this special edition, we present peer-reviewedup-to-date studies which focused on the mechanisms of PBMand its clinical applications.

The original research articles covered many aspects ofPBM, from basic biomedical research to clinic applications,from in vitro cell-based studies to in vivo human tissues. Inthe two review papers, the authors proposed an interestingtheory of PBM based on the function-specific homeostasis,which is a negative feedback response for a function to beperfectly performed. Besides the studies on PBM, we alsoselected several papers on photodynamic therapy and lasersurgery in the current issue.

We highly appreciate the quality, originality, and noveltyof the studies submitted to this special issue, and we welcome

the proposal of the journal to publish a second special issuededicated to the field of PBM in the near future.
