Acne vulgaris is a chronic inflammatory disorder of the pilosebaceous unit affecting more than 85% of adolescents and often persisting into later adulthood. Conventional therapy with antibiotics and retinoids yield mixed results and can be complicated by antibiotic resistance and adverse treatment profiles... The porphyrins within the sebaceous follicles absorb the blue light most effectively at 405 to 415 nanometer wavelengths... Blue light excitation leads to photo-excitation of porphyrins for subsequent release of singlet oxygen and reactive free radicals that has an antibacterial effect on acne bacteria.
