When the skin gets injured it responds with the fabrication of macrophages, cells that
are part of our immune system and that are able to absorb dead and damaged cells.
Radiated with red light of about 660 nanometers, these macrophages expelled a
matter that stimulated the generation and dispersion of new subcutaneous
conjunctive tissue or fibroblasts. Surgical wounds sometimes heal very slowly or not
at all and healing may get hindered due to the development of hyper granulation
tissue with chronic ulcer. These defects were sometimes successfully treated by a
radiation with polarised yellow light of about 590 nanometers. It is strongly advised to
consult your physician before applying any light therapy for wound healing.
