This chapter reviews the combined use of platelet-rich plasma and microneedling for cosmetic enhancement but reports no clinical results; the authors highlight existing uses and suggest potential synergistic benefits in dermatology.

This review discusses the challenges in treating alopecia areata and the potential psychological impact, noting that spontaneous hair regrowth often occurs and highlighting the consideration of psychotherapy alongside treatment options; it reports no new experimental results.

This study reports that while both dermaroller and fractional CO2 laser treatments for acne can lead to hyperpigmentation, itching was specifically noted only after fractional CO2 laser treatment.

The document lists various dermatology topics, treatments, and diagnostic methods.

Inflammation may be linked to hair loss, and targeting specific enzymes could help treat it.

This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.

This review discusses newer therapeutic techniques for treating postacne scarring, highlighting their effectiveness for particular grades of scars, and reports no new clinical results.

This review indicates that microneedle bipolar RF and fractional bipolar RF treatments offer significant improvement in acne scarring, with optimal results observed about three months after treatment.

This review discusses traction alopecia in individuals with Afro-textured hair and emphasizes the importance of education to prevent this condition, but it reports no new clinical results.

This study compared the microscopic treatment zones created by different fractional lasers and radiofrequency in swine skin, finding distinct patterns and damage levels for each technology.

This review discusses the dermatology of nonhuman primates and emphasizes the need for a cohesive approach to study and report their dermatologic diseases, without assuming similarities to human or other veterinary conditions.

This study found that a serum-free DMEM-F12 medium with 45% oxygen best supports in vitro development and differentiation of human fetal skin, closely mimicking the in vivo state.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

In this study, microneedling with a depth of 0.6 mm, alongside minoxidil, significantly improved hair count and thickness in patients with androgenetic alopecia compared to minoxidil alone, and was more beneficial than a 1.2 mm depth.

This paper presents a case of a young male with linear and annular lupus panniculitis of the scalp, detailing trichoscopic findings and their correlation with histopathological features, but reports no new generalizable results.

In this study, researchers found that the absence of P-selectin delays inflammatory cell recruitment and reepithelialization in fetal wounds, although scar formation still occurs in later gestation wounds.

This study reviewed eight studies investigating transcutaneous drug delivery via fractional laser and microneedling for alopecia treatment, with six studies showing improved hair regrowth over topical therapy alone, suggesting its potential as a promising treatment strategy, although further research is needed to refine treatment parameters.

This study proposes an innovative treatment for stretch marks by combining skinbooster and microneedling techniques, which induce tissue remodeling and collagen synthesis, and suggests using confocal microscopy as a valuable tool for monitoring skin changes in aesthetic dermatology.

This case report describes an 80-year-old patient whose scalp wound healed by secondary intention, with unexpected hair regrowth observed at 180 days, suggesting hair neogenesis is possible even in older adults.

In this study, pediatric patients with overt polyautoimmunity frequently had systemic lupus erythematosus as an index disease, with clustering patterns revealing familial influence on autoimmune disease aggregation.

This review discusses major dermatologic conditions occurring in the early post-hematopoietic stem cell transplant period and reports no new clinical results; it underscores dermatologists' role in recognizing critical complications.

In this study, QR678® and QR678 Neo® injections significantly improved hair density and thickness in women with PCOS-related alopecia over eight sessions, with effects lasting over a year.

This study used single-cell ATAC sequencing to map chromatin accessibility in developing mouse hair follicles, offering insights into the transcriptional regulation and epigenetic mechanisms underlying hair follicle development.

This article describes using hair transplantation as a novel method to improve the appearance of acne scars, but it reports no clinical results.

This review discusses approaches to diagnosing and managing cutaneous manifestations of lupus erythematosus and reports no new clinical results.

In this study, 65% TCA showed better improvement for acne scars compared to 50% GA, but GA may be a safer alternative with fewer adverse effects.

This review outlines the transition from simple hair follicle organoids to immune-competent microphysiological systems, addressing limitations in replicating native hair follicle immune features and discussing their applications in disease modeling and regenerative medicine.

This meta-analysis found that autologous cell-based therapies, especially stromal vascular fraction, significantly improved atrophic acne scars over control treatments, enhancing both clinical and patient-reported outcomes.

In this review, the authors highlight the crucial role of mesenchymal stem cells in dermatologic therapies, noting their potential to enhance skin structure and appearance through regenerative mechanisms like inflammation induction, angiogenesis, and recruitment of tissue-specific progenitors.

This review evaluated current evidence on minoxidil's potential to treat scars and reported reduced collagen accumulation and fibrosis in various studies, suggesting its antifibrotic effects may benefit wound healing; however, direct studies on acne scars are yet to be conducted.
