This report describes a 60-year-old female with pretibial pruritic papular dermatitis who showed significant improvement of skin lesions after one month of treatment with oral pentoxifylline. The authors highlight the unique clinical and histological features of PPPD and propose pentoxifylline as a potential therapy.

Postinflammatory hyperpigmentation causes dark skin patches and needs personalized treatment.

This study found that Mueller Matrix microscopy can accurately identify, detect, and evaluate hair follicles in mouse skin tissue, suggesting its potential for skin structure research and dermatological applications.

This study found that using a PEG-400/oleic acid mixture as an optical clearing agent enhanced the detection depth of particles in skin without causing dehydration, based on tests in rats and further testing in vivo.

This abstract discusses the non-invasive technique of scalp micropigmentation for hair loss, focusing on its cosmetic effects and customization options, and reports no new research findings.

This study found that an extract treatment showed similar efficacy and tolerability to calcipotriol/betamethasone ointment in reducing psoriasis severity and symptoms over 28 days in patients with mild-to-moderate plaque psoriasis.

Recognizing IPPP is crucial to prevent misdiagnosis and unnecessary treatments.

This study reports that a patient with rare linear lichen planopilaris experienced complete hair regrowth after 12 weeks of treatment with the antibody ixekizumab, suggesting it as a potential targeted therapy.

Scalp micropigmentation is a process where tiny dots of pigment are tattooed onto the scalp to create the appearance of a shaved head or fuller hair.

This study demonstrated that intradermal treatment with a medical device using Polynucleotides High Purification Technology (PN HPT) significantly improved skin surface, firmness, pigmentation, and radiance in 30 Asian subjects, with benefits lasting up to six months and no adverse events reported.

This phase 2a trial evaluated Samcyprone for common wart treatment and found that while a sensitization reaction is necessary for therapeutic response, its level does not predict wart clearance.

This study found that PRX102, a peroxidase with a unique polar localization pattern, plays a role in root hair growth by aiding the transport of materials to the tips of growing root hairs.

This study concluded that the Scalp Photographic Index is a reliable and validated tool for objectively classifying and scoring various scalp conditions.

This study confirmed known adverse events and identified new ones related to ixekizumab, offering preliminary safety insights for its clinical use, but noted limitations such as potential underreporting and confounding factors in the spontaneous adverse event reporting systems.

This study investigated a nanostructured system using PS-b-PAA diblock copolymer for incorporating the hydrophobic photosensitizer ClAlPc, finding it effective in causing cellular damage in Caco-2 cells under light while demonstrating no cytotoxicity without light, suggesting its potential use in photodynamic therapy.

In this study, deep phenotyping of 68 patients with XPD gene defects successfully separated individuals by clinical diagnosis and survival status, potentially improving diagnosis and prognosis for xeroderma pigmentosum and trichothiodystrophy.

In this study, 5-aminolevulinic acid photodynamic therapy did not improve hair growth in patients with androgenetic alopecia but was safe and slightly reduced scalp sebum secretion.

In this study, DMC selectively eliminated senescent cells in old mice, prevented hair loss, improved motor coordination, and reduced senescence-associated secretory factors, suggesting its potential as a senolytic treatment.

This study reported that specific inhibition of the classical complement pathway with BIVV009 prevented C3 deposition along the dermal-epidermal junction in bullous pemphigoid, reflecting its potential efficacy.

This study developed a digital tool for quantitatively assessing hair in androgenetic alopecia, achieving an average accuracy of 79.45% for counting hairs and 68.19% for measuring hair size compared to human evaluation.

This study demonstrated that a single multimode fiber can be used for single-shot wide-field reflectance imaging, achieving high correlation with the ground truth and enabling real-time microendoscopy at up to 180 frames per second.

This review discusses the development of IPL devices, highlights their established cosmetic uses, such as treating vascular and pigmented lesions, and suggests potential expansion into more effective combination therapies.

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

This study highlights the prevalence of photographic bias in before-and-after images in dermatology, emphasizing how factors like lighting and camera angles can mislead patients and influence expectations, often leading to dissatisfaction and unrealistic aesthetic standards.

This study found that cPPARγ and dnPPARγ isoforms are differentially expressed in healthy human skin, suggesting that PPARγ modulators may have compartment-specific effects depending on isoform presence.

This infographic compares the safety profiles of SH‑1, a cosmetic ingredient, which showed no systemic absorption, and PP405, an investigational drug with dose-dependent systemic uptake and potential threshold breaches, highlighting differences in safety between cosmetic and investigational substances according to this report.
