This study found that increasing commensal bacterial load on the skin enhances wound-induced hair follicle neogenesis in mice, mediated through IL1R-MyD88 signaling pathways.

This study found that fibromodulin significantly reduces scar formation and boosts scar strength in rodent and porcine models, suggesting potential for FMOD-based therapies in cutaneous wound repair.

This review highlights research reporting that oral collagen peptide supplements are effective in enhancing skin elasticity, hydration, and reducing wrinkles, although results vary across studies. Oral supplementation was generally well-tolerated, and further investigation is needed to optimize formulations and explore topical application challenges.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

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 study found that collagen peptides from Mozambique tilapia significantly promoted hair regrowth and increased the proliferation of hair growth factors in vitro and in vivo, suggesting potential as supplements for hair loss prevention.

Burn scars form abnormally due to changes in wound healing, and more research is needed to improve treatments.

This study demonstrated that using PLGA nanoparticles to deliver chlorogenic acid significantly increased type 17 collagen production in human epidermal cells, indicating potential for improved skincare formulations.

This study found that both marine and bovine collagen peptides may help prevent hair loss by supporting epithelial hair follicle stem cell functions, with marine peptides maintaining hair in the growth phase and bovine peptides increasing stem cell presence in hair follicle regions.

This review reports that oral collagen peptide supplements may improve skin elasticity, hydration, and wrinkle appearance while also supporting hair and nail health and wound healing, but emphasizes the need for longer, high-quality studies due to current research limitations and variability in findings.

This study reported that atelocollagen enhances collagen synthesis and reduces oxidative stress in aged skin by increasing glycine uptake through GlyT1, resulting in improved skin elasticity and collagen density in aged mice, with effects superior to glycine alone.

In this study, the researchers developed a cellulose nanofiber-based scaffold containing sitagliptin and zinc sulfide nanoparticles, which promoted scarless healing and hair follicle regeneration in rats by targeting DPP4+ fibroblasts, suggesting a novel approach for improved wound healing and skin regeneration.

This review highlights the use of microneedling devices and patches to deliver cosmetic agents through the skin, noting their applications in skin rejuvenation and safety considerations such as potential skin irritation and infection.

This review explores the potential of multifunctional bioscaffolds in skin tissue engineering, highlighting their successful biological performance in vitro and in vivo animal models, while also identifying the demand for technological advancements to improve wound healing applications in clinical settings.

This review discusses recent advancements and ongoing challenges in engineering human skin with appendages using scaffold-free and scaffold-based bioengineering approaches, but it reports no new clinical results.

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 study found that applying a topical inhibitor of TGF-β1 may enhance scar maturation and improve the appearance of hypertrophic scars in a nude mouse model after two weeks.

This study found that "micro skin tissue columns" improved wound healing by enhancing re-epithelialization, collagen deposition, dermal remodeling, and reducing inflammation without causing long-term donor site morbidity.

The study characterized the transcriptional changes in porcine SKP cells transitioning to fibroblast-like cells, indicating potential roles for specific signaling pathways in this cell fate transition.

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 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.

In this study, the researchers found that combining physical dermabrasion with chemical peeling increased growth factors and neuropeptides more than chemical peeling alone in porcine skin samples.
