This study found that using a home-use LED mask with specific wavelengths improved signs of skin aging in both ex-vivo and clinical settings.

This study found that using an LED array with an 863 nm wavelength delayed tumor development and reduced systemic inflammatory cytokines in DMBA/TPA-induced mouse skin tumors, suggesting potential but limited benefits of light therapy.

The study discusses using red light therapy for hair regrowth, noting red light alone may aid non-inflammatory hair loss, while infrared-red light combination is necessary for conditions like alopecia areata.

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 review discusses the effectiveness of non-thermal, non-ablative devices like light-emitting diodes in treating various skin and hair conditions but reports no new clinical findings.

This review discusses the mechanisms, scientific support, and FDA clearance of photobiomodulation mask devices but reports no new research findings.

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 study found that 1,540 nm fractional erbium-glass laser treatment combined with topical minoxidil significantly increased hair regrowth in alopecia areata patches compared to minoxidil alone, with response rates of 60% versus 16%, though the long-term effects remain unknown.

This study reports that LED phototherapy is gaining popularity as a safe and effective non-invasive method for treating various skin conditions, enhancing skin rejuvenation, wound healing, and inflammation modulation, and is increasingly integrated into clinical protocols for conditions like acne vulgaris and signs of aging.

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.

This study found that near-infrared LED therapy enhanced ATP synthesis, reduced reactive oxygen species, and promoted collagen production and hair growth more effectively than white LEDs in human skin cells and a photoaging mouse model.

This review examines the diverse roles of SRD5α enzymes across species, focusing on their involvement in steroid synthesis, sexual development, and various physiological processes, but reports no new clinical results.

This study reported that a 3D-printed LED photobiomodulation device is technically and financially feasible, but requires further experimental and clinical testing before being used in human healthcare.

This review discusses the modest efficacy of home-use laser and light devices for conditions like hair removal and acne, noting limited evidence and a lack of robust trials.

This article reviews home-use laser and intense pulsed light systems for hair removal and growth, noting limited efficacy and safety data and emphasizing the need for long-term studies.

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 found that LED therapy, using light in specific wavelengths, may offer effective, non-invasive treatment options for various skin conditions, including acne, melasma, photoaging, and wound healing.

This study found that biostimulant application in lettuce cultivation led to significant yield and phytochemical enhancements, with effects varying between green and red cultivars depending on the treatment method used.

The researchers reported that corticosteroid treatments for alopecia areata led to clinical improvement but did not significantly alter oxidative stress markers, suggesting a limited regulatory effect on these systems.

This study found that overexpressing the BMP inhibitor Noggin in transgenic mice led to a significant loss of nontylotrich hair follicles, suggesting a critical role for BMP signaling in hair follicle morphogenesis and cycling.

This study found that conditional knockout of N-WASP in keratinocytes of mice led to skin barrier defects, increased immune cell infiltration, and hyperproliferation of keratinocytes, indicating its crucial role in skin homeostasis.

In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.

This study suggests that increased use of anticancer drugs from 2004 to 2008 has led to higher environmental release, necessitating expanded monitoring and research on their ecotoxicological impacts.

In a conditional knockout mouse model, this study found that loss of the transcription elongation factor SPT6 in basal keratinocytes led to psoriasis-like skin inflammation and delayed wound healing, suggesting SPT6 plays a crucial role in maintaining epidermal immune quiescence by suppressing proinflammatory NF-κB signaling.

This study found that disrupting the microtubule cytoskeleton in Arabidopsis root hairs caused loss of growth directionality and suggested microtubules interact with calcium gradients to regulate apical growth stability.

This study found that long-term use of a home-use LED device for neck skin rejuvenation significantly improved wrinkle appearance and skin biophysical parameters without affecting thyroid function or morphology after 16 weeks of daily use.

In this study, chitosan nanoparticles loaded with phenobarbital were the most effective in promoting hair regrowth and quality in a mouse model of chemotherapy-induced alopecia, suggesting potential for preventing hair loss in cancer patients.

Photobiomodulation effectively stimulates hair growth and reduces hair loss.
