Metaanalysis of clinical efficacy and tolerability of at-home low-level blue and red light therapy technology in the treatment of mild to moderate acne

Acne vulgaris is a multifactorial skin disease, characterized by proliferation of bacteria, hyperkeratinization, inflammation, and excess sebum production, mainly prevalent in adolescents and young adults. Various types of blue and red light-emitting diodes (LEDs) have been used independently and in combination as an alternative, chemical-free option for the treatment of acne. Recent research has demonstrated the significant antiinflammatory activity of red light via modulation of cytokine release and its effect on hyperkeratinization and further research has elucidated the antibacterial efficacy of blue light (up to 440 nm) through its interaction with the porphyrin produced by P.
