A 308 nm excimer laser successfully treated a boy with a rare skin condition after about a year of weekly sessions.

This review assessed evidence on laser therapies for alopecia areata, reporting that the 308-nm excimer laser showed hair regrowth in several studies, while more research is needed for other laser types.

This case study reports that treating a female patient with facial partial unilateral lentiginosis using a 532-nm Nd:YAG fractional picosecond laser resulted in significant improvement in pigmentation without notable side effects, indicating it may be an effective and well-tolerated treatment option.

In this preclinical study, researchers developed and evaluated a new non-invasive laser system designed for personalized medical use, showing its potential for chronic disease management and adjunctive fat reduction by offering enhanced treatment precision and adaptability over existing devices.

This review discusses applications of light diffraction in healthcare, highlighting its use in LASIK procedures, optogenetics, and measuring hair diameter, but reports no new results.

In this study, the HairLux fractional radiofrequency device was found to be effective and safe for stimulating hair growth in androgenetic alopecia, with patients experiencing increased hair density and thickness after ten treatments.

This study demonstrated that Reverse Protein Engineering can decrease the size of Firefly Luciferase from 550 to less than 80 amino acids, but further research is needed to ensure these smaller peptides retain bioluminescent activity.

This review discusses the potential of optical techniques for diagnosing and treating oxidative stress-related hepatic ischemia-reperfusion injury, highlighting the need for non-invasive diagnostic methods and the anti-oxidative potential of optical therapies; it reports no new clinical results.

This study identifies key attributes—luminosity, structural integrity, and vitality—that define hair vibrancy, providing insights to guide the development of hair products that align with consumer expectations.

This study highlights examples of successful hair growth using combined laser therapy and autologous exosome therapy, suggesting a synergistic effect that may enhance beauty treatments and other therapeutic applications.

This abstract presents supplementary materials illustrating trichoscopy in alopecia areata and scarring alopecia using different dermoscopy techniques but reports no clinical findings.

This study found that low-level pulsed wave red light stimulated collagen and ATP production in human fibroblasts with significantly shorter treatment time than continuous wave light, suggesting enhanced consumer compliance for skin treatments.

Both skin products were equally effective in improving facial discoloration and skin quality.

This letter reports a homozygous missense mutation in the LIPH gene causing autosomal recessive hypotrichosis simplex in a Chinese patient.

This review discusses various applications of low level laser therapy and argues for a holistic evaluation of patients but reports no new clinical findings.

This article discusses the use of low-level laser therapy for hair regrowth in men and women but reports no new clinical results; it reviews types of lasers and evidence from animal and human studies.

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 study found that exposing seasonally anestrous mares to extended light periods led to the earlier onset of endocrinologically normal estrous cycles, potentially allowing earlier breeding and foaling.

This study found that hydrophobic amino acids from egg white hydrolyzed protein and L-phenylalanine effectively penetrate deep into the human hair fiber, increasing specific contents in both virgin and bleached hair.

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 cases and research on paradoxical hair growth after laser hair removal and explores laser and light therapies for treating alopecia, but reports no new results.

This study found that using a nonablative 1927 nm wavelength laser followed by hydroquinone cream is safe and effective for treating postinflammatory hyperpigmentation in patients with dark skin types.

This review discusses laser/light treatments for pattern hair loss and reports no clinical validation of current devices; experts recommend physician evaluation to exclude other medical conditions.

This review discusses the current evidence and highlights gaps in research needed for the wider acceptance of low-level laser therapy as a treatment for hair loss; no new clinical results are provided.

This abstract presents supplementary trichoscopy images for alopecia areata and scarring alopecia but reports no clinical findings.

This study engineered a bioluminescent yeast strain responsive to androgenic chemicals, demonstrating rapid and sensitive detection suitable for high-throughput screening and environmental monitoring.

This study employed a laser-based method to analyze how light reflection patterns vary on human hair fibers, revealing changes related to hair color and the tilt of the cuticle cells.

This study introduced laser particles as a new imaging probe capable of real-time tracking of thousands of individual cells in 3D tumor models, suggesting potential for advanced single-cell analyses.
