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.
Claims20
A method 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, wherein the lesion reaches at least the dermis of the skin, the method comprising:
- directly irradiating the lesion with electromagnetic radiation having a wavelength comprised between 410 nm and 430 nm for an exposure time long enough that an energy density received by the outer surface of the lesion is comprised between 15 J/cm2 and 120 J/cm2.
A method of treatment of an already formed scar or keloid on mammalian skin to avoid its recurrence, the method comprising:
- surgically removing the scar or keloid to form an area of the skin with a lesion defining an outer surface which reaches the dermis;
- and
- directly irradiating the lesion with electromagnetic radiation having a wavelength comprised 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.
