Blue Light


All living organisms are capable of interacting with Light. This interaction can have very different effects: from the stimulation of repair and healing processes where there is damage or pathology, to the slowing down or inhibition of physiological processes, up to cell death that is necessary to inactivate pathogens such as bacteria and viruses.

In recent years, thanks to Italian research and the activity of Emoled, it has been found that certain wavelengths of visible light in the range of Blue (410-430) are able to naturally help the healing process of skin lesions. Recently, the same wavelengths have shown an inactivation effect on various types of viruses, including SARS-COV-2.

Blue LED Light in Burns.

Blue LED Light in Burns.

First Case Series published on the Journal of Clinical & Investigative Dermatology.

Photobiomodulation with Blue Light therapy was tested as a new practice in the management of patients with severe burns at the Burns Center and Emilia Romagna Regional Skin Bank, M. Bufalini Hospital, Italy. The article “Blue LED Light in Burns: a new treatment’s modality”, published on the Journal of Clinical and Investigative Dermatology, reports the results of this clinical experience. Blue lIght treatment was performed for 60 seconds twice a week for a maximum period of ten weeks at the time of dressing change and after wound cleansing with distilled water.

9 out of the 11 patients treated, presented with failed autologous skin graft. Surgical procedure of autologous graft is performed as the standard of care on burns of deep second/third degree. However the autologous graft has a probability of failure with total or partial detachment of the grafted skin. When it happens the healing process of the lesion occurs by secondary intention but it is not always easy to manage as this process can be delayed or stopped by many factors such as comorbidities, infections, metabolic deficiencies and advanced age of the patient; moreover sometimes the critical conditions of the patients can be real contraindications to surgical approach. For this reason not invasive therapies instead of or after surgery have to be considered in order to accelerate the wound healing with as little scarring as possible. Authors registered the reactivation of the reparative process of the burned areas where the autologous graft was not successful, with complete re-ephitelialization in 8 cases and an 80% reduction of the lesion area in one case. In some cases also the aesthetic results were taken into account and a better morphology of the recovered skin was observed in the treated areas.
