This review study focused on various in vitro methods to evaluate skin permeation and retention of sunscreens, highlighting the importance of assessing sunscreen penetration due to widespread nanomaterial usage and advancements in cosmetic formulation.

This study found that UV radiation exposure during a simulated Brazilian summer caused more significant mechanical damage to natural hair than bleaching, although both caused comparable structural alterations, with double bleaching leading to the most severe protein degradation.

This study found that deleting β-catenin in epidermis-specific VDR knockout mice did not prevent UVB-induced skin tumors, indicating β-catenin does not compensate for VDR's role in tumor suppression.

This study found that overexpression of PKCɛ in mouse epidermis increased sensitivity to metastatic squamous cell carcinoma, suggesting that a PKCɛ-mediated microenvironment may promote cancer development through specific cytokines like TNFα.

This case report describes an instance of autosomal recessive uncombable hair syndrome caused by maternal uniparental disomy of chromosome 1.

This study found that overexpression of the enzyme ornithine decarboxylase in transgenic mice led to UVB-induced skin tumors, but this was prevented by the ODC inhibitor α-difluoromethylornithine.

This study utilized ultrasound biomicroscopy to evaluate the anterior chamber in angle closure glaucoma patients, revealing that the anterior chamber angle is wider on the downside than the upside and identifying important parameters for potential laser surgery.

This article describes a method using the CUBIC protocol to clarify and visualize molecular and cellular interactions in mouse skin biopsies at single cell resolution, but does not provide new biological findings.

This study found that 3D imaging may serve as a promising tool for objectively evaluating facial vitiligo repigmentation after treatment with upadacitinib.

This study found that low-dose UVB radiation enhances the survival, migration, and hair growth-promoting capacity of adipose-derived stem cells in mice through the generation of reactive oxygen species.

This study suggests using a handheld dermatoscope may allow for simple and efficient differentiation of eruptive vellus hair cysts by detecting vellus hair shafts, as demonstrated in a familial case involving five women.

This study reported that using UVB preirradiation and anti-CD154 antibody treatment in a humanized mouse model prolonged hair follicle allograft survival and reduced immune cell infiltration without needing generalized immunosuppression.

This study found that ultraviolet A rays damage all hair types, with stronger adverse effects on colored and permanently waved hair, suggesting the use of sunblock products for hair protection.

This study found that adipose-derived stem cell extracellular vesicles reduced wrinkles and promoted cell proliferation in UVB-induced photoaging in mice by decreasing oxidative stress and inflammation.

In this study involving rat vibrissa follicles, U. japonica extract was found to enhance hair growth by increasing dermal papilla cell proliferation and accelerating the anagen phase but did not inhibit 5α-reductase activity, which is linked to androgenetic alopecia.

A new genetic mutation causing Xeroderma Pigmentosum was found in an 8-year-old girl, affecting her DNA repair.

This study found that high-dose UVA-1 therapy appeared to improve both patient-reported outcomes and objective clinical measures in patients with morphea and systemic sclerosis, supporting its potential efficacy for treating scleroderma.

This article reviews evidence suggesting that vitamin D and its metabolite may help protect against nonmelanoma skin cancer, but reports no new empirical findings.

This review discusses the integration of ultrasound in dermatology for improved lesion visualization and diagnosis, highlighting recent technological advancements like handheld devices and high-frequency probes, and reports no clinical results.

This study found that PUVA-turban therapy was a well-tolerated and potentially effective treatment for certain patients with severe, treatment-resistant alopecia areata, inducing hair regrowth in some cases.

This study reported that a single treatment using macrofocused ultrasound energy with a 2 mm transducer significantly reduced pore count, pore volume, and pore index in 34 Thai subjects with enlarged facial pores over a 6-month period, with no adverse events observed.

In this study, researchers found that specific treatment parameters disrupted follicles and sebaceous glands, damaging the bacteria Cutibacterium acnes and promoting follicular remodeling, which may improve both inflammatory and noninflammatory acne lesions.

This study evaluated a novel hand-held low-level light therapy device for treating mild-to-moderate acne, finding it significantly reduced inflammatory lesions and moderate acne severity without severe adverse reactions, while also reducing Cutibacterium acnes viability in vitro.

In this research, SEU-302, a newly developed covalent organic framework, exhibited significant antibacterial and wound-healing properties in vitro and in vivo, effectively eliminating Staphylococcus aureus and reducing inflammation under light activation, thereby showcasing its potential for therapeutic photodynamic applications.

This study found that nanobubble-encapsulated diclofenac with ultrasound-targeted microbubble destruction (DNBs-UTMD) can enhance the anti-tumor efficacy of Doxil® by regulating the tumor immune microenvironment, improving drug uptake, and increasing T cell responses while reducing immune-suppressive cells in the process.

This article does not contain an abstract and presents no new clinical findings, instead discussing prior cases and literature on infant alopecia universalis and the potential role of topical PUVA therapy.

This case report describes the occurrence of eruptive vellus hair cysts in twin patients, adding to the literature on this dermatological condition.

This study found that mice lacking the vitamin D receptor (VDR) developed skin tumors more rapidly than those with normal VDR activity, regardless of 1,25-dihydroxyvitamin D(3) presence.

This study observed that long-term UV-A exposure and semi-permanent dye treatment can cause significant structural damage to human hair, particularly affecting the cuticle and cortex layers.
