In this study, participants with androgenetic alopecia who used an LED helmet emitting red and green light experienced significant improvements in hair growth measures, with red light showing superior results in increasing hair diameter and reducing vellus hair density over 6 months.

In this study, a solitary patch of significant hair regrowth was observed in a patient with refractory alopecia universalis under the site of a smartwatch emitting green, red, and infrared light, supporting photobiomodulation as a potential treatment for alopecia areata.

In this study, photobiomodulation therapy using EccoVet® equipment was applied to a canine patient with alopecia, leading to noticeable hair regrowth after just one session and complete improvement after five, highlighting its potential as a fast, non-invasive treatment for canine alopecia.

This review discusses current and emerging treatments for benign prostatic hyperplasia and emphasizes the need for further research to optimize treatment selection, but reports no new clinical results.

New acne treatments show promise as alternatives to traditional therapies.

This study found that red light accelerated the transition from the resting to growth phase in hair follicles faster than green and blue light in mice, suggesting it may stimulate hair growth.

This study found that exposure to red LED light may improve fibre quality and hair follicle development in Angora rabbits, potentially due to increased melatonin secretion.

This study found that irradiating human adipose-derived stem cells with green OLEDs enhanced their wound healing capability and increased cell proliferation, migration, and adhesion in preclinical models.

This study found that multiple treatments combining NIR laser phototherapy with ICG significantly reduced inflammation and improved skin condition in acne without side effects.

This study found that combining near-infrared laser phototherapy with indocyanine green application may improve acne vulgaris by reducing active lesions and inflammation without side effects.

This article reviews advancements in carbon dots for tissue engineering and regenerative medicine, highlighting challenges and future directions without presenting new clinical findings.

In this review, the researchers highlight LED therapy as an emerging and safe treatment for skin inflammatory conditions, aging, and hair growth disorders, noting its integration into dermatological practice but emphasizing the need for more controlled studies to confirm its efficacy.

In this study, polarized light therapy increased hair regrowth in patients with alopecia areata compared to those who received only minoxidil.

This review discusses the application of low-level light therapy for hair loss treatment, particularly androgenetic alopecia, and reports no new clinical results; the authors suggest consideration of light source characteristics and potential pros and cons.

This review discusses the applications of low level laser therapy (LLLT) in wound healing, pain reduction, and treating various conditions, but reports no new clinical results; the authors highlight the need for randomized controlled trials for serious diseases.

This review compares the CO2 and Er:YAG laser treatments for acne scars, noting that while CO2 lasers offer deeper tissue penetration for severe scars, Er:YAG lasers pose a lower risk of post-inflammatory hyperpigmentation, and recommends personalizing treatments and considering combination therapies.

This study found that LED light irradiation induced proliferation and migration of human outer root sheath cells, potentially through the stimulation of the Wnt/β-catenin and ERK signaling pathways.

This review discusses the applications and advantages of LED-based photobiomodulation therapy for dermatological and cosmetic purposes but highlights existing challenges and health concerns while exploring future perspectives.

This study observed that adding low-level light therapy with the GentleWaves® device to Minoxidil significantly boosted hair regrowth in men with androgenetic alopecia by reducing scalp inflammation.

Low-Level Laser Therapy can stimulate healing and cell function, potentially leading to wider medical use.

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.

This review discusses the potential of repeated low-level red-light therapy to inhibit myopia progression through metabolic effects, highlighting its molecular and cellular impact, but reports no new clinical results.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This study found that isolated red light may serve as an alternative for photo-immunotherapy without additional photosensitizers, as it did not reduce keratinocyte differentiation markers or increase photo-oxidative damage, unlike treatment with IL-4 or UVA1/blue light.

This narrative review explored how blue light therapy may offer therapeutic benefits for various skin disorders by affecting microbial activity and immune responses, promoting hair growth, and aiding skin rejuvenation and healing.

This study found that low-level laser therapy significantly increased hair growth in women with androgenic alopecia, achieving a 37% greater increase in hair counts compared to placebo.

This study found that 655-nm red light with LED enhanced hair shaft elongation and reduced catagen transition in human hair follicles in vitro by activating the Wnt/ß-catenin signaling pathway.

This study evaluated a novel hand-held low-level light therapy device for treating mild-to-moderate acne, finding it significantly reduced inflammatory lesions and moderate acne severity without severe adverse reactions, while also reducing Cutibacterium acnes viability in vitro.

This review discusses herbal therapies for dermatologic disorders, focusing on those with scientific evidence of efficacy and common interactions, but reports no new clinical results.

This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.
