This study found distinct skin surface changes, including faint mosaic melanoderma and atypical scaliness, on long-standing sun-exposed balding scalps that may be associated with actinic field carcinogenesis.

This study supports the idea that inflammation may play a role in the development of androgenetic alopecia, as indicated by certain immune deposits and porphyrins found more frequently in bald scalp biopsies compared to controls.

This study observed that applying polyamines to the skin of hairless mice stimulates thymidine incorporation, suggesting polyamines may play a role in DNA synthesis control in the epidermis.

Excimer laser therapy can be an alternative for treating superficial morphea when topical steroids don't work.

This study suggests that Medicago sativa extract, combined with UVA light, may enhance pigmentation in hypopigmented skin and hair, offering potential treatment for vitiligo.

Light therapy can effectively treat vitiligo and hair loss caused by a specific medication.

This study found that four out of ten patients with alopecia areata experienced some hair regrowth after PUVA therapy, though this treatment should be reserved for those unresponsive to other options due to potential long-term side effects.

This study found that Cream 1 effectively prevented UV radiation-induced nerve ending damage in human skin samples, unlike placebo and SPF15 creams.

This study found that Gelidium corneum, a type of red seaweed, may serve as a promising source of bioactive compounds for skin health, showing photoprotective and healing properties in vitro and antioxidant and stability benefits in vivo when used in dermocosmetic formulations.

This study reports that a plant extract from Orobanche rapum can stimulate skin rejuvenation and protect cutaneous microbiota, potentially creating healthier skin.

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

This review discusses topical calcineurin inhibitors for cutaneous lupus erythematosus and reports no new clinical findings; the authors emphasize the need for more comparative studies with corticosteroids.

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 concluded that while home-based intense pulsed light, laser diodes, radiofrequency, and light-emitting diode devices are recommended for certain skin conditions, ultraviolet B phototherapy for psoriasis showed mixed evidence compared to clinic treatments.

The skin acts like an endocrine organ, making hormones that affect skin diseases and respond to stress.

This article reviews the use of phototherapy for alopecia areata and highlights its potential due to the therapy's modulatory effects on the skin's immune system, but it presents no new research findings.

This chapter hypothesizes that vitamin D signaling in the skin may suppress UV radiation-induced epidermal tumor formation, reviewing potential mechanisms without reporting new clinical results.

This study observed hair-specific transcription of a reporter gene in transgenic mice, with increased expression after dexamethasone and ultraviolet B treatment.

This study outlines the features and diagnosis of Vogt-Koyanagi-Harada disease, highlighting its association with specific genes, its prevalence among pigmented races, and treatment with systemic steroids and immunosuppressants.

This study demonstrated a method for delivering a photosensitizer, Ammi majus fructuum furocumarines, into hair follicles using calcium carbonate particles, followed by UVA irradiation, which led to significant pigment accumulation, indicating potential improvements for photochemical therapy.

This study suggests that local skin inflammation may enhance the deposition of autoantibodies in the skin, potentially affecting the severity of pemphigus lesions in mice.

This study developed a genetic toolbox to engineer Cutibacterium acnes for dermal applications, successfully creating a strain that secretes antioxidants to reduce oxidative stress in a UV stress model.

This preclinical study observed that a nanoencapsulated ingredient complex, AcPi, may prevent hair follicle aging and hair loss by reducing oxidative stress, enhancing mitochondrial activity and WNT/β-catenin signaling, and controlling androgenic metabolism when tested on human scalp cultures.

This article discusses the potential for topical caffeine as a natural alternative for treating androgenetic alopecia due to its ability to penetrate skin, but it reports no new clinical findings.

This study found that the immune-competent B6. Cg‐Tyr c−2J Hr hr /J congenic mouse line had a more pronounced delayed sunburn response and different proliferative skin reactions to UV exposure compared to SKH 1 mice.

This study found that a new 12-point scale provided a more precise measurement system for evaluating hair damage and improvement after hair care product use compared to a 5-point scale.

Minoxidil reacts to nitrosation 7 times more than phenol, mainly due to its -NH₂ groups, leading to the creation of N-nitrosominoxidil.

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

This review discusses the potential of extracellular vesicles for facial aesthetic applications, including scar reduction and skin rejuvenation, but reports no new clinical results; further research into production and mechanisms is needed.
