This review discusses the effects of vacuum massage on skin structures and concludes that there is insufficient evidence for its efficacy in treating burn scars, suggesting more research is needed on its potential benefits and mechanisms.

Raspberry ketone lacks sufficient human research to support health benefit claims and requires more rigorous studies to confirm its safety and effectiveness.

The study found that a single autologous micrografting treatment using Rigenera® technology significantly improved the appearance of stretch marks in healthy women after three months, showing greater enhancements in skin properties compared to microneedling alone.

This study examined the preservative and antimicrobial susceptibility of non-fermenting bacilli collected from beauty salon waste in Brazil.

In this study, oral administration of strawberry guava extract promoted hair growth in both mice and humans, with active components like adenosine, fructose, digalactosyldiacylglycerol, and pedunculagin contributing by enhancing skin blood flow and activating dermal papilla cells.

In this cross-sectional study of healthy urban women in Shanghai, poor sleep quality and elevated perceived stress were linked to various self-reported dermatological issues and clinical signs, reinforcing the potential relevance of psychological factors in skin health.

This review discusses current advancements in mesenchymal stem cell-based therapies for skin repair and rejuvenation, focusing on therapeutic strategies, particularly highlighting the potential of neonatal and placenta-derived MSCs, and reports no new clinical results.

This study explores the complex mechanisms of skin aging, including cellular senescence and disrupted communication, and highlights rejuvenation strategies like gene expression rewiring and microbiome modulation, offering potential frameworks for regenerative therapies and precise interventions in skin and systemic aging.

This review highlights that exosomes from adipose-derived stem cells, particularly those enriched with circ-Ash1l, can inhibit ferroptosis and reduce UVB-induced skin aging by delivering GPX4-promoting signals to damaged cells, thus offering a potential regenerative therapy for photoaged skin.

This review provides a comprehensive synthesis of skin aging research, highlighting the interplay of genetic and environmental factors, cellular mechanisms, and advances in diagnostic and therapeutic strategies, while also addressing current debates and future directions in the anti-aging field.

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 explores the potential of mesenchymal stem cells in skin regeneration and rejuvenation, highlighting their ability to modulate immune response and enhance extracellular matrix strength but does not provide new clinical evidence.

This review suggests that although hydrolyzed collagen peptides with certain supplements may improve skin elasticity and joint function, evidence for collagen's anti-aging and regenerative benefits remains inconsistent.

This review found that hydrolyzed collagen supplementation, particularly marine collagen, improves skin hydration, elasticity, and density while strengthening hair and nails, especially when paired with vitamin C and trace elements; however, more studies are necessary to evaluate long-term efficacy across different sources and demographics.

This review reports significant advancements in plastic surgery using stem cell therapies for aesthetic and reconstructive applications, including grafting and wound healing, though it underscores the need for continued research to address regulatory, ethical, and standardization issues.

In this study, researchers found that an injectable solution of low-molecular-weight hyaluronic acid and amino acids significantly improved skin rejuvenation and elasticity in the labia majora of post-menopausal women over 12 weeks, with a reported 25% or greater aesthetic improvement and high patient satisfaction.

This study found that sericin dressing containing collagen hydrolysate significantly reduced wound healing time and improved scar quality compared to commercial dressing in split-thickness skin graft donor sites.

This report observed that repeated stellate ganglion blocks over six years were associated with improved skin elasticity, increased water content, and more hair follicles on the treated side of a patient's face.

This study reports that a new multi-slit knife for hair transplant procedures reduces surgical time and increases precision by enabling quick creation of equidistant "brick-pattern" sagittal slits.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

In this study, researchers found that wound healing in mouse skin recruits diverse fibroblasts, including myeloid-derived cells, which contribute to regenerating adipocytes.

PGD2 stops hair growth and is higher in bald men with AGA.

This study observed that baricitinib treatment led to significant improvement in a patient's alopecia areata symptoms and suggests further clinical trials to explore its potential as a treatment.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

The researchers reported that dsRNA from damaged skin activates TLR3, promoting hair follicle regeneration, while TLR3-deficient animals fail to initiate this process, suggesting potential therapeutic approaches for hair neogenesis.

This study found that overexpression of Smad7 in transgenic mice led to severe alterations in multiple epithelial tissues, resulting in early death after birth.

This review discusses advanced techniques for investigating stem cell fate at the single-cell level, including lineage tracing, time-lapse imaging, and molecular profiling, but reports no new research results.

This study found that carbon nanotube impurities induced immunological toxicity in mice, whereas purified nanotubes showed good biocompatibility, suggesting high-temperature thermal treatment may improve nanotube biocompatibility.

This study reports the successful differentiation of mouse induced pluripotent stem cells into keratinocytes that can regenerate skin and its structures in an in vivo environment.

In this study, researchers developed a method to differentiate human iPSCs into cells that can generate all lineages of hair follicles, potentially aiding treatments for hair loss and skin disorders.
