Fluorescent Light Energy and wound healing: a good news?

Since ancient time, the light has been considered as treatment in order to promote wound healing In the last years a new kind of technology has been approved on the market. Previously known as biofluorescence or photobiomodulation, nowadays the Fluorescent Light Energy (FLE) is based on the unique ability of light accepting molecules (chromophores) to translate light emission from a lamp (LED blue lamp) in a different photons emission with broader wavelengths spectra and lower energy (fluorescence). This technology permits to stimulate both exogenous chromophores, through a gel directly applied on the wound bed, and endogenous chromophores, activating the wound healing process. The blu light, indeed, is translated in different colors (yellow, green and orange) with consequent impact on all skin layers (epidermis, papillary and reticular dermis). Here we present our experience with FLE in patients affected by chronic and acute wounds. Materials and Methods: We enrolled 50 patients affected by chronic or acute wounds as vascular ulcers (30 patients), II degree burns (20 patients).After obtained informed consent we performed pictures and we treated the lesions with FLE for 5 minutes twice a week. After debridement (if required) a gel containing chromophores has been applied on wound bed and activated by a multi LED blu lamp. The median number of sessions has been 10. All the patients have been treated in hospital as recovery or as outpatient. Results: All the treated patients reported an improvement in wound healing with a complete rehepithelization in 90% of the cases. In the last 10 % the treatment prepared the wound bed to surgery (skin graft). We also noted the stimulation of melanocytes in high skin phototype Conclusions: In our experience FLE has been an unpainfull treatment with an high compliance of the patients. The study confirmed its efficacy in inducing healing or preparing the wound bed to surgery.
