This systematic review found that exosomes and gut microbiota play a significant role in skin regenerative processes, suggesting that gut health is crucial for maintaining aesthetically healthy skin, and probiotic treatments may support traditional dermatological therapies for inflammatory skin diseases.

This study developed a gas-propelled microneedle patch with puerarin/quercetin nanoparticles, which demonstrated improved hair-regenerating effects in an androgenetic alopecia mouse model by increasing drug delivery, alleviating oxidative stress, promoting angiogenesis, and rejuvenating senescent cells.

This review highlights the positive effects of platelet-rich plasma in aesthetic and regenerative medicine, particularly for skin rejuvenation, anti-aging, hair reconstruction, and wound healing, but it reports no new clinical results.

This study used Cisd2 knockout mice models and found that these mice display premature aging characteristics and an increase in dysfunctional neutrophils, suggesting Cisd2's role in calcium homeostasis and neutrophil function via interactions with Calnexin and SERCA.

This review explores how radiation-induced hair graying can be used as a model to study the mechanisms behind hair graying, focusing on cellular senescence and potential therapeutic targets to address age-related changes. Results are not provided.

This study found that Rap1 deficiency in mice may lead to telomere shortening, DNA damage, and impaired mitochondrial function, contributing to cardiac aging and dysfunction.

This review outlines the various fibroblast subsets in the skin dermis, their origins, and their influence on epidermal stem cell behavior, highlighting the role of the local dermal niche in stem cell plasticity.

Skin problems in the elderly are unique and may indicate other diseases, involving changes in skin, hair, nails, and increased cancer risk.

This paper reviews existing research on the cosmetic benefits of hemp-derived cannabinoids for skin and hair, highlighting their unique mechanisms of action, while discussing formulation, legal, and regulatory challenges associated with using these compounds in cosmetic products.

This study aimed to investigate the effects of antioxidant therapy on skin aging in MetS patients in Latvia but provides no new findings on its effectiveness.

This review discusses the potential of single cell technologies to improve understanding and treatment of impaired wound healing and reports no new clinical results.

This review discusses the effects of estrogen on skin and reports no new clinical results; it highlights estrogen's potential benefits on skin thickness, collagen quality, and hair follicle life cycle.

This study found that in mice, dermal adipocytes initiate inflammation and aid repair after skin injury by releasing lipids, suggesting a role in managing inflammatory diseases and impaired wound healing.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

This review discusses the role of signaling networks in sebaceous gland development and disorders, highlighting recent insights from mouse models and cell line studies, but reports no new experimental results.

This review reports on the dual aspect of fullerene in skincare, highlighting its beneficial antioxidant properties as well as potential toxicity and skin cell reactions, while identifying areas for future research.

This review examines cell senescence pathways in melanocytes, highlighting the involvement of telomere attrition, the p16/RB pathway, and cAMP signaling in the context of melanoma development, but reports no new findings.

This review discusses the varied use and inconsistent reporting of platelet rich plasma in aesthetic surgery, finding that current studies lack consistent methodologies and objective evidence, and reports no new clinical results.

This review discusses various techniques for evaluating hair shedding and alopecia but reports no new clinical results. The authors emphasize the value of specific clinical and instrumental methods in assessing hair growth.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This review discusses the role of cholesterol homeostasis in hair follicle biology and its potential connections to various hair disorders, but it reports no new findings.

This study identified sex-specific determinants for facial wrinkles, finding that age is the strongest factor and that lifestyle influences like smoking, alcohol use, and skin color differentially affect wrinkling in men and women.

This study found that long-term dutasteride therapy in men with benign prostatic hyperplasia worsened erectile dysfunction, reduced testosterone levels, and increased blood glucose and lipid profile, indicating negative metabolic impacts.

This review discusses environmental factors like UV radiation and smoking that affect hair health and highlights the potential role of nutrition, but it reports no new results.

This review discusses the potential link between long-term transdermal exposure to sex hormones from antiperspirants and increased breast and prostate cancer rates, calling for further research to confirm this theory.

This review discusses clinical presentations and interventions for alopecia in women of color, highlighting the importance of early recognition and treatment but providing no new clinical results.

In this retrospective study at Lausanne University Hospital, 61% of 48 patients with tendinopathies reported favorable outcomes after a single standardized autologous PRP injection, while 36% needed two, and effectiveness was unrelated to platelet concentration, activity level, age, or gender.

This article reviews how stem cell exhaustion contributes to aging, emphasizing the balance between proliferation and quiescence as crucial for long-term stem cell maintenance, but it reports no new results.

This study found that young host mice rejuvenated aged hair follicles after transplantation, while aged host mice did not support hair growth from transplanted follicles.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.
