This article explores the potential of photobiomodulation for coronary health, suggesting protective effects after heart attacks and in inaccessible ischemic heart conditions, but presents no new clinical results.

This study found that diode laser effectively reduces unwanted facial hair in darker skin types and reported no serious adverse events, suggesting that trichoscopy is an underutilized tool for assessing laser hair reduction outcomes.

This study found that LED light therapy may stimulate skin regeneration and wound healing, with various wavelengths affecting fibroblast proliferation, collagen synthesis, and hair growth in experimental settings.

This review highlights advancements in hair laser removal technologies, which achieve approximately 75% hair reduction in light-skinned individuals, noting the long-pulsed Nd:YAG laser as safest for dark-skinned patients, but reports no new results.

This review discusses the use of laser and intense light sources for hair removal and reports no new clinical results; the authors highlight the potential for aesthetic medicine to include these technologies.

This systematic review found widespread support in existing literature for the effectiveness of low level laser therapy in promoting hair growth, but emphasized the need for larger case-controlled studies to confirm these results.

This study found that while both professional and home-use lasers effectively reduced axillary hair, the professional Diode laser was significantly more effective, achieving 85-88% reduction compared to 46-52% with the home-use laser, which still offers some safety for users.

This study concluded that intense pulsed light treatment effectively thinned hair to achieve a natural look after hairline correction surgery in East Asian women with naturally thick hair.

This study reported that four patients with lichen planopilaris showed dramatic improvement, including symptom reduction and hair regrowth, after treatment with low-level light therapy.

This review discusses the effects of low-level laser therapy in various biological processes for wound healing and tissue repair and reports no new results.
