We are happy to publish a link to this June 2023 study that concluded as follows:
"This clinical study confirms the interest of photobiomodulation in the treatment of the signs of skin ageing. From the very first sessions, whatever the age of the person, the visible effects of reversing the signs of ageing are not only observable but also measurable."
630nm was the chosen wavelength for the study. You can read full details via the link below.

Reverse skin aging signs with photobiomodulation @ 630nm red light
Recent study confirming the positive effects of red light therapy for reversing skin ageing. 630nm was the wavelength studied, but other studies also show benefits from higher wavelengths.
