What is a chromophore?
A chromophore is a molecule or molecular structure that absorbs specific wavelengths of light.
In Photobiomodulation (PBMT), chromophores like cytochrome c oxidase (CCO) absorb red or near-infrared light, initiating biological responses such as increased ATP production.
Red light therapy for hair restoration targets chromophores within scalp tissues, triggering energy production and repair processes that support hair follicle health and growth.
