Eating fewer calories may slow aging and removing old cells can increase lifespan in mice.

Healthy aging can be promoted through physical activity, lifestyle changes, and certain treatments.

This review outlines various clinical methods for assessing ageing skin and discusses their application in supporting the efficacy claims of anti-ageing treatments, but it reports no new clinical results.

This study found that age and follicular miniaturization were extremely weak predictors of total hair count in women with hair loss.

In this study, pneumatic injections of non-cross-linked hyaluronic acid were associated with improvements in skin texture, pores, wrinkles, and transepidermal water loss in healthy female volunteers.

In this study, researchers found that differences between self-ratings and assessor ratings of facial appearance vary by age and ethnicity, and these discrepancies, along with assessor ratings of skin features, are predictive of menopausal status across ethnic groups.

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.

In this study, using far-infrared oily cream for massage therapy was associated with increased normal cell telomere length and improvements in stress-induced hair and skin conditions.

This Delphi consensus study provides expert insights into hair aging, aims to enhance diagnostic precision and management of age-related hair changes, and identifies possible new therapeutic targets.

This review discusses the mechanisms and treatment strategies for age-related hair changes, such as androgenetic alopecia and hair graying, and reports no new clinical results.

This article reviews current understanding of dermal fibroblasts' structure and function, highlighting their crucial role in connective tissue formation and repair, which is important for selecting effective treatments for age-related skin changes.

This article reviews the skin and hair changes associated with menopause due to hormonal shifts and reports no new clinical results.

This review discusses age-related and environmental factors affecting scalp hair changes in women, highlighting diagnostic complexities and ongoing research into targeted treatments, without reporting new clinical results.

In this study, older women aged 70 and above, treated for sexual dysfunction using carefully monitored hormone therapy, reported improvements in sexual function and symptom relief, with no incidences of cancer or thromboembolic events, though some experienced breast tenderness and hair changes.

This review highlights current evidence showing that hormonal changes significantly influence skin aging, with estrogen decline during menopause having a major impact on women's skin health, while testosterone decreases contribute to aging in men.

This review highlights essential preoperative assessments for ophthalmologists and non-oculo-facial surgeons performing upper facial rejuvenation, emphasizing the importance of understanding ocular and periocular anatomy to achieve both cosmetic and functional improvements.

This study investigated age-related changes in female scalp dermal fibroblasts, finding alterations in gene and protein expressions associated with fibrosis and senescence, which could potentially affect hair follicle health and contribute to aging-related hair changes.

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 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.

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

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 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 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 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 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 study found that hair follicles undergo significant molecular changes with age, notably a decline in keratins and keratin-associated proteins, which may contribute to age-related hair alterations.

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 study reports that aging in mice leads to curved hair follicles and an increase in white hairs, potentially due to changes in keratinocyte and melanocyte stem cells.

This study found that some white or grey hairs can naturally regain pigmentation, suggesting hair greying may be reversible in certain conditions linked to psychological stress.

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