<p>Disclosed is a device that can heal skin wounds and grow hair by irradiating light from light emitting diodes (LED). The device is provided with: an ultra-narrowband light irradiation means which generates ultra-narrowband red light with peak wavelength range 620-660nm and FWHM 10nm or less; an ultra-narrowband light irradiation means which generates ultra-narrowband green light with peak wavelength range 500-540nm and FWHM 10nm or less; an ultra-narrowband light irradiation means which generates ultra-narrowband blue light with peak wavelength range 440-480nm and FWHM 10nm or less; and an ultra-narrowband light irradiation means which generates ultra-narrowband red to near infrared light with peak wavelength range 700-2500nm and FWHM 10nm or less. In this way, cell growth factors such as HGF and KGF are acted upon by irradiating the affected area with ultra-narrowband monochromatic light of FWHM 10nm or less, which has excellent effects in healing skin wounds and growing hair.</p> |
