This study observed that specific genes in cashmere goat skin exhibit a seasonal rhythm, potentially adapting to environmental light changes, which may affect downstream gene expression and physiological processes.

This review article evaluates new treatment techniques for androgenetic alopecia, including low-level laser therapy, platelet-rich plasma therapy, microneedling, and topical growth factors and peptides, reporting positive outcomes such as hair regrowth and improved hair density and thickness.

This review discusses the applications and challenges of lipid nanosystems in various fields, comparing techniques for evaluating nanoparticle properties, and reports no new experimental results.

This case report describes a 4-year-old girl with hypotrichosis and juvenile macular dystrophy, linked to mutations in the cadherin 3 gene affecting P-cadherin expression.

In this study, combining treatment for acne and sensitive skin improved clinical outcomes and skin physiological function more significantly than treating acne alone in patients with acne and sensitive skin.

This study found that Piezo2 channels are primarily located on sensory axon membranes in mechanosensory end organs, supporting a model where mechanical stimuli activate Aβ RA-LTMR neurons via axon protrusions.

This review found that many low-level light therapy studies report beneficial effects but often fail to provide adequate measurement details, affecting the reliability and repeatability of the research.

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 study found that early life stress significantly affects hedonic sensitivity to high-palatable food by altering gonadal hormones in prenatally-stressed male and female rats, with sex-dependent changes in reward-related behaviors and neurochemistry.

In this study, isotretinoin treatment in women with severe acne increased body weight and triglycerides but did not affect androgens or insulin sensitivity.

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.

In this study, researchers found that the glabrous skin of the rat forelimb contains sparse Meissner corpuscles and Merkel complexes, with more slowly adapting afferents in the palm and rapidly adapting afferents in the digit extremity.

In this study, researchers observed that dietary vitamin D intake and light exposure play a crucial role in vitamin D metabolism in mice, suggesting similar importance for human health in maintaining optimal vitamin D levels.

This systematic review found that cinnamon supplementation may modestly improve insulin sensitivity and potentially reduce hyperandrogenism in women with PCOS, but stresses the need for large-scale clinical trials.

This review concluded that LED-based photobiomodulation is generally safe and effective for certain dermatologic conditions, though consumer devices often show less efficacy compared to professional systems.

In this study, researchers observed that inhibiting myosin light chain kinase in hair cells reduced stiffness and oscillation in bullfrog hair bundles and increased hearing thresholds in mice.

This article reviews recent imaging and genetic tool advances that enable in vivo study of hair regeneration and assessment of skin parameters, but it reports no new clinical results.

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

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 review evaluates photobiomodulation's diverse clinical uses in sports and medicine, reporting physiological modulation and potential therapeutic benefits, but emphasizes the importance of precise dosimetry for success.

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 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 light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

This study found that spironolactone reduced fish fecundity and caused masculinization of females at certain concentrations, while having no effect on Daphnia magna reproduction, underscoring concerns for environmental exposure to vertebrates.

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 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.

In this study, ultraviolet light did not significantly enhance or worsen hair growth induced by topical minoxidil in men with male pattern baldness.

This article reviews the use of various treatments for alopecia and their potential impact on COVID-19 outcomes, emphasizing the importance of patient registries in generating real-world evidence; it reports no new results.

This study found that combining topical finasteride with IPL + RF hair removal significantly reduced unwanted facial hair in women after six months compared to placebo.

HEV light can harm or help skin and scalp, so safe exposure guidelines are needed.
