The sequential wound healing cascade promotes optimal repair. However, prolonged or overly vigorous individual phases impede healing. Although most wound therapies focus on initiating the healing process by supplementing growth factors or matrices, the study by Hellmann et al. highlights the role of lipid molecules termed resolvins, specifically RvD1 and RvD2, as promoters of epithelial wound closure.

The innumerable intricacies associated with chronic wounds have made the development of new painless, noninvasive, biophysical therapeutic interventions as the focus of current biomedical research. Red and near-infrared light-induced photobiomodulation therapy appears to emerge as a promising drug-free approach for promoting wound healing, reduction in inflammation, pain and restoration of function owing to penetration power in conjunction with their ability to positively modulate the biochemical and molecular responses. This review will describe the physical properties of red and near-infrared light and their interaction with skin and highlight their efficacy of wound repair and regeneration. Near-infrared (800–830 nm) was found to be the most effective and widely studied wavelength range followed by red (630–680 nm) and 904 nm superpulsed light exhibiting beneficial photobiomodulatory effects on impaired dermal wound healing.
