Abstract: A method is presented to prevent formation of a scar or keloid following an insult to an area of a mammalian skin creating a lesion defining an outer surface, where the lesion reaches at least the dermis of the skin. The method includes irradiating the lesion with electromagnetic radiation having a wavelength between 410 nm and 430 nm for an exposure time long enough that the energy density received by the outer surface of the lesion is comprised between 15 J/cm2 and 120 J/cm2.
Abstract: A method for the inactivation of viruses and/or bacteria by at least 50%, or the disinfection and sanitization from bacteria and/or viruses, in spaces, surfaces or objects uses an electromagnetic radiation having a wavelength comprised between 410 nm and 430 nm. In particular, it relates to irradiating the area to be disinfected or sanitized with an electromagnetic radiation having a wavelength comprised between 410 nm and 430 nm for a time interval between 5 minutes and 180 minutes, a power density comprised between 13 mW/cm2 and 120 mW/cm2 and an energy density comprised between 30 J/cm2 and 220 J/cm2. The electromagnetic radiation is irradiated at a distance between the source of the electromagnetic radiation and the irradiated space, surface or object between 30 centimeters to 1.5 meters.
