LED Diode Mask (Photobiomodulation)

Photobiomodulation (PBM) is the therapeutic use of non-thermal light at specific wavelengths to modulate cellular function. The LED diode mask at Artmedica delivers four distinct spectral bands, each interacting with different chromophores and cellular targets in the skin to produce distinct biological effects.

Red light at 625–700 nm is the most extensively studied PBM wavelength. Its primary cellular target is cytochrome c oxidase in the mitochondrial respiratory chain — the enzyme that catalyses the final step of oxidative phosphorylation. Absorption of red light by this chromophore increases the enzyme's activity, leading to greater ATP production, reduced oxidative stress and reduced levels of pro-inflammatory reactive oxygen species. Fibroblasts exposed to…

Blue light at 440–500 nm targets porphyrins produced by Cutibacterium acnes — the bacterium driving inflammatory acne. When C. acnes porphyrins absorb blue light, they generate singlet oxygen and other reactive oxygen species that are lethal to the bacterium but cause no damage to surrounding human tissue at the intensities used. Blue light treatment reduces bacterial load in the follicle, decreasing the inflammatory cascade that produces papules and…
