Water-filtered near-infrared influences collagen synthesis of keloid-fibroblasts in contrast to normal foreskin fibroblasts.

What the authors concluded

Our results show that viability was not influenced by irradiation. Independent of the analysed fibroblast species temperature dependent occurrence of spheric cells could be observed. These morphological changes were clearly counteracted by additional light exposure. Convective heat reduced collagen type I synthesis in both cell species depending on the applied temperature. Co-treatment with NIR s
