This study demonstrated that regular use of LactoSporin cream for 10 weeks significantly reduced wrinkles and fine lines in healthy female participants, although improvements in skin elasticity and hydration were not significantly better than placebo when measured by certain instruments.

This study found that taking oral FKH supplements for 90 days improved facial skin, hair, and nail appearance, and highlighted the role of free L-amino acids as potentially beneficial beyond their protein-building functions.

This review discusses the potential skin care benefits of non-denatured soybean extracts, including skin lightening and UV protection, but reports no clinical results.

This study found that a combination of five medicinal plants traditionally used in Chinese medicine significantly improved skin repair and delayed aging markers in laboratory models, suggesting synergistic anti-aging effects over individual ingredients.

This study found that encapsulating coffee berry extract in nanoliposomes improved its stability, reduced toxicity, and enhanced its anti-aging effects on skin elasticity and lightening more than free extract.

This study found that topically applied melatonin exerts significant anti-aging effects on human scalp skin ex vivo, including increased SIRT1 expression and reduced mTORC1 pathway activity.

This study found that bergamot and boxthorn extract significantly improved skin antioxidant activity and collagen content while promoting hair growth in mice.

This study reports that the tetrapeptide AcSDKP significantly promotes skin and hair health in vitro and ex vivo, suggesting it could be used cosmetically to counteract skin aging and hair loss.

In a study on mice, cow placenta extract showed strong antioxidant activities and reduced collagen damage, suggesting it could help delay skin aging caused by D-galactose.

This study found that astaxanthin effectively protected human dermal papillae cells from oxidative stress induced by hydrogen peroxide, reducing the percentage of cells expressing a stress marker significantly, suggesting potential benefits for hair loss treatment related to reactive oxygen species.

This review summarizes how common polymorphisms in androgen and estrogen receptor genes may influence aging-related symptoms and diseases in men, but it reports no new clinical results.

This systematic review found that exosome-based therapies significantly improve skin elasticity, reduce wrinkle depth, enhance hydration, and modulate pigmentation, with minimal adverse events reported across multiple studies. However, further clinical trials are necessary to confirm long-term efficacy and safety.

This review discusses various environmental pollutants and their potential role in promoting mitochondrial dysfunction, which may contribute to aging-related diseases, cancer, and other adverse health outcomes, but reports no new experimental results.

This article argues that the promissory discourse in the anti-ageing treatments market exploits societal anxieties about ageing, but its long-term sustainability is questionable as many promises remain undeliverable.

This study concluded that extracts from fermented pumpkin peel and pulp, processed with Lactobacillus strains and kombucha, may serve as multifunctional cosmetic ingredients, offering antioxidant protection, anti-aging, and skin regeneration benefits by demonstrating cytoprotective effects and reducing inflammatory cytokines in cell assays.

This review discusses the potential medicinal properties and pharmacokinetic features of nettle compounds ursolic acid and quercetin, highlighting quercetin as a promising candidate for antioxidant and anti-aging effects, but reports no new clinical results.

This review outlines the biological effects of various placental extracts, noting their reported antioxidant, anti-inflammatory, and immunomodulatory activities, but highlights that the relationship between these effects and the extracts' specific contents remains unclear.

This study found that collagen oligopeptides from puffer skin may reduce skin melanin and increase hydroxyproline content in guinea pigs, suggesting potential skin whitening and anti-aging effects.

This article reviews various studies and suggests that melatonin, produced both naturally in the skin and applied topically, may offer significant protection against environmental damage, making it a promising candidate for skincare therapies.

This meta-analysis reported that platelet-rich plasma significantly improved patient satisfaction and objective efficacy in treating skin aging, while not significantly increasing adverse effects.

This study found that Polygoni Multiflori Radix (PMR) reduced collagenase and elastase activity after UVB damage in fibroblasts, suggesting potential anti-aging properties for cosmetic use.

This study indicated that while testosterone replacement in older men with low testosterone increases muscle mass and strength and reduces fat, its effects on physical function, disability, falls, or fractures remain unclear.

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 study concludes that egg shell membrane hydrolysates, particularly Fraction I, may effectively mitigate UV-B radiation-induced wrinkles and promote skin collagen and hyaluronic acid production, suggesting potential use in functional cosmetics.

In this mouse study, UVA and UVB exposure led to hair follicle miniaturization, graying, and prolonged hair cycle duration, associated with changes in stem cells and increased Wnt signaling activity.

The researchers reported that Gambogic Amide may prevent hair greying and promote hair growth by maintaining follicle pigmentation in vitro through activation and migration of melanocytes.

This study found that honokiol inhibits enzymes related to testosterone degradation in vitro, suggesting its potential as a lead compound for developing antiaging bioactive ingredients for men.

This study investigated the effects of 10600nm CO2 dot laser and Nd: YAG laser on Wistar rats' skin, finding that CO2 laser treatment resulted in higher positive expression of MMP-1 and TIMP-1 compared to Nd: YAG laser, with statistically significant differences noted.

This review discusses the broadening scope of botulinum toxin applications beyond traditional uses, highlighting its effects on non-neuronal cells and potential in treating various dermatological conditions, without reporting new clinical findings.

This review discusses how ionizing radiation causes skin damage by inducing cellular senescence in keratinocytes, which secrete inflammatory mediators, recruiting immune cells and exacerbating inflammation, impacting the skin barrier function and healing.
