In this study, researchers introduced a visible-light-mediated intramolecular cycloaddition method that selectively forms 6-azabicyclo[3.1.1]heptanes, suggesting these structures could offer promising new scaffolds for drug discovery and medicinal chemistry.

This review highlights the role of the skin's photosensory system in mediating responses to UVA radiation, contributing both to immediate protective effects and to broader circadian and seasonal adaptations, but reports no new experimental results.

This editorial reviews how photobiomodulation therapy might effectively treat both hyperpigmentation and depigmentation skin disorders, but reports no new clinical results.

This review discusses recent surgical and medical advancements in hair restoration techniques but reports no new clinical results.

In this study, researchers found that punch grafting was more effective than follicular hair transplantation for treating stable vitiligo; however, follicular hair transplantation was found to be cosmetically preferable for exposed areas like the face due to fewer side effects.

Dermoscopy greatly improves melanoma diagnosis and reduces unneeded surgeries.

UV dermoscopy helps detect white hairs in children more effectively.

This chapter reviews differences in dermatological treatments and conditions between male and female patients, particularly noting the impacts of sex steroids on various skin processes, but presents no new clinical findings.

This systematic review and meta-analysis found that minoxidil, finasteride, and low-level laser light therapy significantly improve hair growth in men with androgenetic alopecia, while minoxidil is also effective for women, compared to placebo.

This abstract explains that androgenetic alopecia, a common hair loss disorder influenced by genetics and hormones like dihydrotestosterone, has FDA-approved treatments including minoxidil, finasteride, and photolaser therapy, but its genetic basis and susceptibility to environmental factors remain complex.

This study achieved over 99% antibacterial efficacy against Staphylococcus aureus and Escherichia coli by modifying camel hair with Rose Bengal, allowing for color customization and strong mechanical properties under visible light, thus suggesting a high-value approach to diversifying camel hair textiles.

This study found that camel hair treated with the photosensitizer Rose Bengal exhibited strong antibacterial properties against Staphylococcus aureus and Escherichia coli when exposed to visible light, achieving over 99.90% bacterial inhibition and maintaining robust mechanical strength.

SeV-Tp speeds up healing of drug-resistant infections by targeting wounds and killing bacteria with light activation.

This study suggests that using a dermoscope, a handheld microscope, can effectively help distinguish between Pityrosporum folliculitis and Acne vulgaris by revealing unique lesion characteristics that are not visible to the naked eye, offering a practical diagnostic alternative when KOH examinations are unavailable.

This study proposed that the tiger tail phenomenon in trichothiodystrophy hair is caused by regular undulations of hair fibers, altering the optical properties seen under polarized light.

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.

This article discusses current visualization methods for assessing hair restoration therapy responses, noting imprecision in triangulated measurements and patient dissatisfaction with visible tattoos.

This review compiles existing research on infrared radiation's effects on human skin, noting both its potential harmful thermal impacts and encouraging therapeutic applications, but reports no new clinical results.

This study found that a combination of photoprotector and nighttime formulations with essential oils improved skin barrier function and structural characteristics in young men's oily, acne-prone, and photoaged skin.

This case report documents a rare association between atopic eczema and pili annulati in two siblings from north India, an unusual finding not previously reported in the literature.

UV-enhanced trichoscopy helps diagnose hair shaft disorders like pili annulati.

Combining scalp photos with hair density and caliber measurements gives a more accurate assessment of hair loss.

This study identified specific dermoscopic features for differentiating rosacea, seborrheic dermatitis, contact dermatitis, and atopic dermatitis, suggesting dermoscope's value in diagnosing facial erythema with atypical presentations.

In this article, researchers explored how blue light exposure affects the scalp and hair follicles, highlighting oxidative stress and hair growth disruptions, while emphasizing the importance of protective strategies like antioxidants and limiting light exposure.

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 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 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.

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 review suggested that low-level light therapy using red/near-infrared light could be a safe and effective treatment for various skin and hair conditions, though more robust trials are needed to solidify its clinical utility.
