This review discusses the role of fibroblast heterogeneity in determining skin scarring versus regeneration and reports no new results, highlighting opportunities for developing antiscarring therapies.

This study investigated dermal fibroblasts in mouse skin using single-cell RNA sequencing and identified signaling pathways that influence adipogenesis, finding that IL-1-NF-κB promotes, while WNT-β-catenin inhibits, the adipogenic potential of these cells, with implications for wound healing and scar formation.

This review examines the potential of swellable microneedles in drug delivery and diagnostics, highlighting innovations and challenges in their use for chronic disease treatment, but noting that issues like physiological responsiveness and long-term stability still require research.

This review summarizes the mechanisms of mesenchymal stem cell-mediated wound healing and highlights engineering strategies that enhance therapeutic outcomes, but it reports no new clinical results.

This review highlights recent advancements in microneedle technology, noting its ability to enhance transdermal drug delivery, biosensing, cancer treatment, and skin disease repair, while emphasizing its potential for improving patient compliance and reducing side effects.

This review discusses the psychological and emotional effects of common dermatologic conditions and highlights their impact on quality of life, but it does not present new clinical results.

This study emphasizes the importance of understanding cosmetic procedures and their risks, particularly for individuals with darker skin, and highlights expert recommendations for pre- and post-procedure skin care, including the use of broad-spectrum sunscreen to prevent and improve pigmentation disorders.

This review examines the role of cannabinoid compounds in treating various skin conditions and suggests their potential as systemic and topical therapies, but it reports no new experimental results.

Exosomes show promise in improving skin health and appearance.

This review summarizes current melasma treatments, emphasizing the need for tailored, long-term management strategies that integrate photoprotection and address various pathogenic mechanisms.

This review categorizes contractile hydrogels by their contraction mechanisms and explores their role in advanced wound management, emphasizing mechanical and biochemical signaling in healing, but also notes challenges like force transmission and clinical applicability.

This review highlights recent advances in personalized transdermal drug delivery systems, noting their potential for improved treatment efficacy and safety, but identifies significant challenges in clinical translation.

In this study, the researchers developed a biomimetic multilayer composite scaffold combining a decellularized amniotic membrane, fibroblast-laden collagen gel, and epidermal stem cells, which healed full-thickness skin wounds more quickly and effectively by regenerating hair follicles without scarring compared to Moropicin ointment.

This source reviews current understanding of fibroblast lineage differentiation and its role in wound healing, highlighting the potential to reprogram adult cells for scar-free repair by emulating fetal-like regenerative states.

This study reported that in animal studies of androgenetic alopecia, a biodegradable microneedle patch releasing glutamic acid promoted hair regeneration more effectively than daily minoxidil, with higher hair follicle counts and less frequent dosing, showing the potential for clinical application.

This review suggests that while minoxidil is effective in promoting hair growth, its precise mechanism remains unclear, and it may have emerging applications in treating various dermatological conditions.

This review discusses the potential of exosomes as cell-free treatments for skin aging and various dermatological diseases, highlighting their role in preventing scarring and promoting wound healing, while acknowledging the need for further research and quality control methodologies.

This review discusses the use of human-to-mouse xenografting to study human skin processes in vivo, highlighting its importance for understanding skin regeneration and pathology while identifying knowledge gaps and challenges in applying these findings to human skin.

This review outlines the current state of stem cell therapy in dermatology, highlighting its potential for treating a variety of skin disorders and conditions, while emphasizing the need for further controlled studies to standardize treatment and fully understand its efficacy and limitations.

This review summarizes recent findings on the role of mesenchymal stem cell-derived exosomal microRNAs in skin regeneration and rejuvenation, discussing their potential for treating skin damage and aging, and exploring bioengineering methods to enhance therapeutic effects.

In this case series, researchers observed a rare presentation of lichen planopilaris confined to the face in six patients, with dermoscopic and histopathological profiles indicating scarring alopecia and pigment changes, and suggested that shaving and mustard oil use might trigger the condition.

Scalp micropigmentation usually needs two to three sessions, but factors like genetics, coverage area, and health conditions can require more.

This study develops FR-1, a topical small molecule, which reduces scarring and avoids skin atrophy in a murine wound model, showing potential for treating fibrosis without the side effects of current therapies.

In this narrative review, the authors explored various rehabilitative techniques, including injections and physical therapies, that may enhance aesthetics and psychosocial wellbeing in patients with disabilities, emphasizing a multidisciplinary approach to improve both functional and cosmetic outcomes.

In this updated guideline, the British Association of Dermatologists' expert group provided 49 management recommendations for alopecia areata and highlighted future research priorities, aiming to improve care for individuals affected by this condition.

This review summarizes available evidence on the dermatological use of platelet-rich plasma, particularly noting its efficacy for androgenetic alopecia and skin rejuvenation, but highlights significant gaps due to limited high-quality studies.

This case report highlights that intradermal testing may be more effective than patch testing for diagnosing delayed hypersensitivity reactions to intralesional corticosteroids like triamcinolone acetonide.

A hairless patch on a boy's scalp from birth injury improved with minoxidil treatment.

This article discusses the potential role of telocytes in skin regeneration and the need to understand their interaction with platelet-rich plasma, reporting no new experimental results.

In this study, hair follicle effacement was identified as a key dermoscopic feature of cicatricial alopecia, and dermoscopy proved useful in distinguishing cicatricial from non-cicatricial alopecias.
