Oral collagen improves skin, nails, hair, and reduces cellulite.

This study found that dietary supplementation with collagen, chondroitin sulfate, low-molecular weight hyaluronic acid, Pycnogenol®, and coenzyme Q10 significantly improved skin hydration, elasticity, nail hardness, and hair condition in patients with age-related dermatological changes after 12 weeks.

This review reports that collagen as a nutraceutical shows promising results for improving skin health in estrogen-deficient women, but more research is needed for scalp hair, nail health, and optimal dosing of curcumin and glutathione.

This study found that the peptide TSN6 increased epidermal thickness and promoted hair follicle formation in dermal–epidermal composites grafted onto nude mice, with TSN6-treated composites showing more hair follicles and retained grafts compared to control groups.

In this clinical study, a vegan collagen builder (VEGCOL™️) was shown to safely and effectively improve hair growth, skin smoothness, wrinkle reduction, and joint pain relief in adults, with enhancements varying by dose over a 60-day period.

This review found that various treatments like finasteride, minoxidil, and platelet-rich plasma, combined with supplements, showed positive responses in combating androgenetic alopecia. The study specifically highlighted finasteride's effectiveness in increasing hair growth, with different dosages yielding notable improvements in both men and pre-menopausal women.

This study found that acellular dermal matrix scaffolds may facilitate full-thickness skin wound healing by promoting a pro-regenerative immune response through M2 macrophage polarization via the Lamtor1 pathway.

This study reported that a newly developed hydrogel composed of recombinant type I collagen and chitosan, incorporating a metal–polyphenol structure, demonstrated strong mechanical and healing properties, effectively promoting wound healing in a full-thickness skin defect model.

This article explores the potential mechanisms by which polydeoxyribonucleotide (PDRN) could improve skin quality, slow aging, and enhance skin regeneration, but reports no new clinical findings.

This review examines recent advancements in electrospun nanofibers for wound healing applications, but reports no new experimental results, highlighting their potential in sutures, dressings, and skin regeneration.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

This review explores how adipose-derived stem cells contribute to skin homeostasis and highlights recent advances in their clinical applications in dermatology, but it reports no new clinical results.

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.

This review discusses the roles of dermal white adipose tissue (dWAT) as an insulator, antibiotic, and regenerative tissue, highlighting its importance in systemic metabolism and immune function, but reports no new clinical results.

This study found that PCL-based nanofiber scaffolds enhanced cell proliferation and extracellular matrix deposition, suggesting they show promise as a cell delivery system for improving skin wound healing.

This review discusses the development and future prospects of biomaterials for in situ tissue regeneration but reports no new research results; it underscores the importance of biomaterials in addressing tissue defects.

This review examines how mesenchymal stem cells and their derivatives may enhance skin regeneration and rejuvenation, but it reports no new clinical results; the authors suggest iPSC-derived MSCs hold promise for future therapies.

This review assesses the benefits and limitations of various supramolecular hydrogels, including polymeric and peptide-based types, for wound healing, but reports no new clinical results.

This study found that a novel skin patch combining extracellular matrix and ciprofloxacin promotes advanced wound healing and skin regeneration in mouse models of infected wounds.

This review evaluates the scientific literature on silicon supplements, noting that orthosilicic acid shows higher bioavailability, but emphasizes the need for further clinical studies on safety and efficacy.

In this study, fibronectin coating on a low-adhesive substratum increased cell aggregation, growth, and motility, enhancing the formation of hair follicle dermal papilla spheroids.

This review discusses potential cell sources and bioengineering strategies for regenerating hair follicles with functional cycling, reporting no new results.

This review explores the potential of using genetically-manipulated stem cells as both therapeutic agents and gene delivery vehicles for enhanced wound regeneration, but it reports no new clinical results.

This study demonstrates that FMOD deficiency in mice alters TGF-β ligand and receptor expression during wound healing stages, leading to delayed wound closure and increased scar size.

This study found that α-MSH administration before skin wounding in adult mice reduced inflammation and scar area, suggesting a potential pathway to more regenerative healing.

This study found that linseed oil, rich in flavonoids and terpenoids, significantly improved burn wound healing in terms of faster contraction, reduced inflammation, and enhanced tissue regeneration compared to other treatments, without adverse effects.
