This study introduced a new laser-only method called EKA for acne treatment, which is reported to be safe, painless, and heat-free, showing promising results for both acne and scar repair in initial sessions without combining with LED light.

Riboflavin with blue light speeds up hair dyeing, making it faster, safer, and long-lasting with less hair damage.

This study examines the effects of excessive or prolonged exposure to blue light on retinal function and highlights its potential health implications, noting that both photoreceptor and intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths.

This study found that LEDs at specific wavelengths may improve antifungal performance and promote hair growth by activating scalp cells without inducing inflammation compared to a non-irradiated group.

This study found that fractional laser treatment significantly enhances the penetration and targeting of certain permeants, such as imiquimod and FD, to skin follicles, but not hydroquinone.

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 830 nm LED light effectively treated post-inflammatory erythema and hyperpigmentation, while both 830 nm and 590 nm LEDs prevented post-inflammatory erythema.

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 demonstrates that confocal laser scanning microscopy can effectively visualize the rapid diffusion and penetration pathway of a dye into the hair follicle in fresh human scalp skin.

In this study, more than 25% of children experienced axial length shortening greater than 0.05 mm/year following repeated low-level red-light therapy.

This review highlights that two-photon excitation microscopy is a valuable tool for visualizing live skin structures and immune responses at high resolution, though its clinical use is hindered by safety and cost issues.

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

USB videodermatoscopes are a practical and affordable alternative for diagnosing skin conditions.

This review covers red light Transcranial LED therapy for hippocampal memory impairment in aging and Alzheimer's but reports no clinical results, highlighting a need for further research into its mechanisms and effects.

This chapter explores the promising use of low-power laser irradiation for post-hysterectomy reconstructive care, emphasizing enhancements like a flexible fiber optic module, to potentially improve genitourinary rehabilitation in cervical cancer patients.

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

This review examines the FDA's 510(k) approval process for low-level laser therapy devices used in treating androgenetic alopecia and reports no new clinical findings.

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.

This study found that using a Picosecond IR Laser (PIRL) on mouse skin led to less tissue damage and scarring compared to conventional surgical lasers and tools.

Flamena, a liposomal mix, helps skin heal better after a chemical burn.

This review examines the therapeutic effects of photobiomodulation on severe medical illnesses but reports no new clinical results; it emphasizes its potential in neurology, pulmonology, inflammation, dermatology, wound healing, and oncology.

This article reviews the growing trend of at-home laser and light devices for treating conditions like acne, hair removal, and psoriasis, emphasizing their popularity and the need for cautious use but reports no new clinical results.

This study reported that a low color temperature light (1900 K) may have positive effects on melatonin secretion, eye protection, wound healing, and hair regeneration compared to higher temperature lights.

This study developed a highly sensitive fluorescent assay for measuring enzyme activity in single hair follicles, allowing the efficient analysis of over 100 samples per day.

In a rodent study, a flexible, self-powered triboelectric nanogenerator wound patch combining electrostimulation and photothermal effects was found to efficiently accelerate wound healing and hair follicle regeneration.

This chapter reviews low-level light therapy for hair growth and loss prevention but reports no new clinical results, providing an overview of mechanisms, treatments, and future perspectives.

This overview of the Dermatologic Surgery journal describes its extensive coverage of peer-reviewed content across various skin surgery techniques but presents no new research findings.

In this study, ultradeformable liposomes containing Tween 20 or terpenes increased phospholipid bilayer fluidity and enhanced skin penetration of sodium fluorescein, with terpenes improving hair follicle penetration.

This article introduces a needleless microjet injector using laser pulse energy for tattoo pigments in scalp micropigmentation, highlighting an almost painless procedure without anesthesia.
