This review discusses the complex effects of testosterone on the brain, emphasizing sex differences, and reports no clinical results; the authors highlight the inconsistencies in current study findings.

This article reviews factors influencing hair aging and available treatments like minoxidil and finasteride for androgenetic alopecia but reports no new clinical results.

This article discusses the potential effects of exogenous testosterone, highlighting that its impact on prostate cancer progression, cardiovascular health, and behavior remains uncertain and needs further investigation.

This study found that young C57BL/6 and BALB/c mice exhibit distinct regenerative patterns during ear wound healing, with greater wound closure but less regeneration in middle-aged C57BL/6 mice.

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 biological and cosmetic aspects of hair aging and reports no new clinical results; it highlights current treatments and future research directions to address both aging factors.

This study observed that taking 500mg/day of Microcore’s Muttaijow ComplexTM for 12 weeks significantly improved the appearance of skin, hair, and nails in healthy middle-aged adults.

This literature review examines current anti-aging therapies, focusing on innovative genetic cosmeceuticals enhanced by nanotechnology, which offer targeted and minimally invasive treatment options by effectively delivering anti-ageing genetic elements to skin cells and potentially improving skin health through reduced oxidative stress.

In this source, the therapeutic potential of jojoba and wheat germ oils is discussed, with a focus on their antimicrobial effects. The article also highlights their various uses in treating skin conditions, supporting body functions, and enhancing overall health.

In this study, PDO, PLLA, and PCL thread implants in ageing rat skin did not alter MMP1 gene expression but maintained collagen levels similar to young skin without UV-B exposure, suggesting possible benefits for skin collagen but not gene expression modification.

This review reports that extracts from the plant Eclipta alba, traditionally used in herbal medicine, may promote hair growth by inhibiting TGF-β1 expression and functioning as a 5α-reductase inhibitor, potentially benefiting androgenic alopecia treatment.

This report details the development of a PSR™ Terminalia extract with antioxidant and anti-aging potential, highlighting its rich composition in phenolic acids, polysaccharides, and organic acids, without new clinical results.

In this study, oral supplementation of Microcore’s TrichovitalsTM significantly improved the appearance of facial skin, hair, and nails over 12 weeks in healthy middle-aged adults compared to a control group.

This study found that extracellular Granzyme B contributes to skin aging and impaired healing in ApoE knockout mice by degrading essential extracellular matrix components like decorin and fibronectin.

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

This study suggests that both age and photoexposure may decrease maximum viable epidermis thickness and impact the dermal-epidermal junction in women with Fitzpatrick skin types II-III.

This study found that ginsenoside Rb1 treatment significantly reduced aging symptoms in mice by regulating cell cycle and apoptotic pathways, potentially linked to metabolic changes.

This study found that the DPP-4 inhibitor linagliptin slowed the progression of premature aging characteristics in klotho-/- mice, including improved body weight, cognitive function, and hair retention.

In this study, lifelong barley intake in SAMP8 mice was associated with extended lifespan, improved aging-related phenotypes, and beneficial shifts in the intestinal microbiome.

This study found that a long-term astrocyte culture model can effectively study astrocyte senescence and suggests minoxidil as a potential candidate to regulate brain aging by normalizing dysregulated gene expression in aged astrocytes.

This study found that hair luster decreases with age in Japanese females, primarily due to an irregular increase in fiber curvature which affects hair alignment.

This study found that human hair follicle-derived mesenchymal stem cells can differentiate into myogenic, osteogenic, adipogenic, and chondrogenic lineages, although this potential decreases over time and varies by lineage.

This review discusses the potential role of Wnt signaling in aging-related heart diseases and reports no clinical results.

The document concludes that there are still unknowns about the effectiveness, risks, and detection of performance-enhancing drugs, and doping remains a challenge.

This study concluded that hormonal replacement therapy can improve skin ageing symptoms by increasing skin thickness and alleviating dryness and hyposeborrhoea in postmenopausal women.

This study demonstrated that troxerutin may protect human dermal papilla cells from H2O2-induced damage and suggests potential in treating alopecia by inhibiting ROS-mediated cellular damage.

This study observed that mice with a whole-body deficiency of Cystathionine-β-synthase developed severe hyperhomocysteinemia and related mild symptoms without increased mortality, indicating HHCy may not directly cause end organ damage.

In this study, Rosa multiflora root extracts showed strong antioxidant activity and promoted expression of growth factors IGF1 and PDGFB, suggesting potential use as a natural hair growth agent.

In this study, researchers highlighted that while hair lipids are crucial for hair health and protection, surfactants in shampoos and conditioners can partially remove these lipids, potentially affecting hair structure, though the exact mechanisms remain poorly understood and require further investigation.

This study found that Hydroxypinacolone Retinoate (HPR) may alleviate UV-induced skin photoaging by enhancing collagen synthesis, reducing degradation, and modulating inflammatory and oxidative responses in a dose-dependent manner.
