This article reviews existing and emerging treatments for psoriasis, focusing on therapy modifications due to scientific advancements, but it does not report new clinical results.

This study reported that sunscreen with SPF50+ provides a high level of DNA protection against UV-induced damage in a reconstituted human epidermis model, comparable to that in skin explants.

Pollution exposure speeds up hair damage.

This study reported the development of a novel and reliable liquid chromatographic method to measure testosterone and epitestosterone in human urine, offering sensitive detection for doping control.

This article discusses recent advancements in treatments for psoriasis, including new drug approvals and innovative therapeutic approaches, but reports no new clinical results.

In this study, a superoxide dismutase gel prevented hair graying in mice exposed to photosensitization, suggesting that antioxidants can protect against oxidative damage involved in hair aging.

This review discusses the chemical composition, potential health benefits, and extraction methods of red ginseng oil, and reports no new clinical results but emphasizes safety and proposed molecular mechanisms.

This study reports that A132, a hair dye ingredient, induces phototoxicity and photogenotoxicity via mitochondrial apoptosis when exposed to sunlight, suggesting potential risks of oxidative stress and hair damage.

This report documents two cases of eruptive nevi occurring in the skin folds of children with Langerhans cell histiocytosis.

This study demonstrated that combining l-cystine and thiamin in a formulation may protect against UV-induced damage in growth-limited human epidermal keratinocytes in vitro.

This study found that conditioned media from human amniotic fluid-derived stem cells may enhance skin regeneration by promoting cell proliferation and migration, and by modulating gene expressions altered by UV irradiation.

This study reports cases of androgenetic alopecia patients with depigmented macules on sun-exposed scalp areas, suggesting potential ultraviolet-induced scalp leukoderma not covered in existing dermatology texts.

This study found that polymorphous light eruption (PLE) may include a wide range of conditions, requiring careful differentiation from similar skin disorders such as benign summer light eruption.

This article proposes that androgenic alopecia might be an evolutionary mechanism for reducing prostate cancer risk by enhancing UV absorption, rather than being a risk factor.

This review explores the clinical characteristics, risk factors, and treatment challenges of scalp basal cell carcinoma, noting its potential aggressiveness and difficulty in treatment, but reports no new clinical results.

This study introduced and validated new spectrophotometric methods to simultaneously determine finasteride and tadalafil in Entadfi™ capsules with high sensitivity and without interference from excipients.

This review highlights that extracts from *Hamamelis virginiana* (witch hazel) exhibit antimicrobial, anti-inflammatory, antioxidant, and wound-healing properties in various studies, showing promise for future therapeutic use in dermatology and cosmetology, particularly for skin treatments.

This chapter reviews dermatological treatments, noting that botulinum toxin A is associated with a higher occurrence of focal weakness compared to controls, and reports on adverse effects of finasteride and PUVA therapy.

This study found that nickel oxide nanoparticles synthesized using Alternanthera sessilis extract may have potential as antimicrobial, antifungal, and dye-removal agents.

This article reviews the functions and locations of skin stem cells and their role in regeneration and differentiation, relating age-associated skin changes to decreased stem cell functionality; it reports no new experimental findings.

This study used a 3D simulation to show that human hair provides varying levels of UV protection depending on head orientation and hair alignment, highlighting hair's role in scalp UV protection, especially for those with alopecia.

This article reviews a variety of research presentations from the Society for Investigative Dermatology's annual meeting, highlighting advances in dermatological research without reporting new clinical results.

This chapter provides an overview of skin physiology, aging effects, and how environmental factors like UV damage impact skin health, without presenting new research findings.

This review discusses the causes and treatments of hair loss in women, such as telogen effluvium and female pattern hair loss, and provides no new research results.

This abstract reviews the unclear link between androgenic alopecia and prostate cancer, highlighting the need for further research to determine the mechanisms connecting these two conditions.

This study found that treating human hair with vitamin E and γ-oryzanol significantly reduced UV-B-induced structural damage, with γ-oryzanol providing greater protection, especially in female hair samples. The findings highlight these compounds' potential as cost-effective solutions for preserving hair integrity against UV damage.

This study highlights the critical role of mitochondria in skin aging and wound repair, suggesting that targeted interventions such as antioxidants, NAD⁺ boosters, and NRF2-based therapies may enhance mitochondrial function and improve cutaneous health.

This study evaluated a hair mask containing rice germ oil GX-N and ferulic acid on damaged hair and found that rice germ oil GX-N improved hair characteristics after bleaching, UV, and heat exposure, but adding ferulic acid did not provide extra benefits.

This case study describes a previously unknown association of the PIBIDS complex with autoimmune thyroiditis and autoimmune hemolytic anemia in a five-year-old Indian child.

This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.
