This article discusses a proposed "Darwinian" model of carcinogenesis and emphasizes that cancer prevention involves more than avoiding mutagens, as gene-environment interactions are complex and non-linear.

This review discusses experimental data, technologies, and genetic factors related to stem cell niches, highlighting their role in tissue regeneration and diseases, but reports no new results.

This study explores the role of cell competition in maintaining genomic quality in epidermal stem cells and proposes that this process might influence cancer development in skin tissues.

This research abstract provides no results, focusing on the equal contributions of the authors in the field of molecular, cellular, and developmental biology from Yale University.

This study reports that aging in human skin involves early photo- and inflammation-related cellular changes, and suggests restoring KLF6 and HES1 expression might reverse some of these age-associated changes.

This article reviews the role of skin surface lipid in mediating environmental stressors and discusses potential therapeutic interventions, reporting no new experimental findings.

This study found that elevated luteinizing hormone levels were significantly associated with female pattern hair loss, and implicated LH/LHR signaling in the aging and damage of hair follicles.

This review explores adult female acne, focusing on its multifactorial causes, treatment options, and impact on quality of life, but reports no new clinical results.

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 discusses how hair characteristics, such as color, thickness, and volume, change with age and hormonal factors, affecting perceived age, and introduces concepts of hair aging and the nuanced diagnosis between androgenic and senile alopecia.

This review discusses the multiple layers of environmental controls on hair stem cell homeostasis and suggests that targeting these layers could offer safer regenerative medicine therapies without directly using stem cells.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

This article discusses the aging-related changes in hair structure and function, and examines various treatments like light therapy, minoxidil, and finasteride aimed at mitigating hair thinning and loss, but reports no new clinical results.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

This article reviews age-related changes in facial structure at a cellular level and summarizes potential solutions for rejuvenation surgery, but reports no new clinical results.

This review analyzed the complex interactions within the skin microenvironment that influence hair follicle development and regeneration, exploring its role in hair-related disease treatment and highlighting research challenges and future directions.

This study reviews the regulatory mechanisms and molecular processes governing stem cell activity in hair follicles, highlighting their roles in hair regeneration and potential implications for treating hair and skin disorders.

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 study found that aging in Korean individuals is associated with changes in hair diameter and surface structure, as observed through atomic force microscopy.

This review discusses the classification and regulation challenges of anti-ageing cosmetics in Europe and reports no new findings; it calls for increased transparency to help consumers make informed choices.

This review detailed the types and mechanisms of injectable "skin boosters" and evaluated their effectiveness and safety for mitigating age-related skin changes, providing insight into their use in contemporary dermatological practice.

This source discusses the ethical dilemmas and business pressures in cosmetic dermatology, emphasizing the shift toward commercialism and profit-driven practices influenced by social media and market demands, potentially leading to conflicts of interest and professional misconduct.

This study reviews current research to better understand how various environmental and lifestyle factors, collectively known as the exposome, impact hair health and aging, acknowledging that the detailed mechanisms remain partially understood.

This chapter reviews the biology and regulatory mechanisms of epidermal stem cells, emphasizing their heterogeneity and roles in skin homeostasis, cancer, and aging, without reporting new findings.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

This study mapped the genome-wide epigenetic landscape in secondary hair follicle stem cells of goats, revealing distinct histone modification signatures associated with cashmere fiber cycling during different stages of hair growth.

This review explores the role of aging-related changes in skin, discussing how impaired skin barrier function may contribute to systemic inflammation, or "inflamm-aging," which in turn could impact the broader decline in organ and tissue function seen in aged individuals.

This review examines intrinsic and extrinsic aging impacts and presents evidence-based lifestyle recommendations to complement cosmetic procedures for enhanced antiaging outcomes, but it reports no new clinical results.
