In this study, fish-derived collagen hydrolysate from tilapia scales improved hair growth and skin health in both cellular and mouse models, reducing oxidative stress and inflammation while enhancing hair quality and promoting beneficial gene expression.

This study investigated tissue healing in cats with auto skin grafts, finding that those treated with a combination of platelet-rich plasma and tilapia skin bio-dressings showed improved tissue structure, reduced collagen density, and more widespread caspase-3 expression compared to other treatments.

Tilapia skin helps heal skin injuries faster and cheaper.

This study presents a novel hydrogel scaffold made from tilapia collagen, which when activated by ultrasound, reprograms macrophages to promote wound healing, enhance angiogenesis, and stimulate hair follicle regeneration, offering a potential new method for treating inflammatory wounds.

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.

This study found that an acellular dermal matrix derived from tilapia skin significantly accelerated wound healing and improved tissue regeneration quality in mouse and pig models compared to a commercial porcine-derived matrix, suggesting its potential as a safe, cost-effective bioscaffold for skin 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.

In this study, researchers applied Strat-M® membrane to assess the in vitro transdermal properties of collagen peptides, finding a high correlation with results from mouse skin and suggesting that Strat-M® can effectively replace excised mouse skin in transdermal experiments.

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 mouse study, researchers found that orally administered low-molecular-weight fish collagen peptides significantly improved hair regrowth by both enhancing growth-promoting pathways and reducing inhibitory mechanisms.

Oral collagen combined with other treatments effectively reduces hair loss and improves hair quality in telogen effluvium.

In this study, APC collagen peptides were observed to enhance hair elasticity and gloss in human hair follicles by increasing amino acid and lipid component levels, suggesting their potential benefits for improving hair qualities.

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 chapter discusses the composition, biocompatibility, and production methods of biomaterials like collagen, chitin, and silk for dermal substitutes, focusing on preclinical and clinical research, but reports no new clinical results.

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 study found that fish scale collagen peptide significantly promoted wound healing in mice, with the <1 kDa fractions enhancing collagen synthesis and reducing inflammation, suggesting potential clinical benefits.

This study found that six-month supplementation with fish-derived collagen peptides, calcium, and vitamin D3 improved skin hydration and elasticity and reduced hair loss in menopausal women, with collagen playing a dominant role in enhancing skin elasticity.

In this study, researchers identified a collagen fragment, sample-1707, expressed in E. coli, which forms nanofibers and promotes blood clotting, osteoblast differentiation, and skin cell regeneration, making it a promising biomaterial for skin care, with a large-scale production yield of 600 mg/L.

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.

The researchers reported that sulfated chitosan-containing sponges can modulate macrophage activity in diabetic wounds, reducing inflammation and promoting angiogenesis and tissue regeneration, which may enhance wound healing outcomes.

This study found that DPG promoted wound healing in rat skin, with increased collagen I density, particularly evident within the first 14 days after injury.

This study found that CLD-hFGF2 hydrogels improved healing in deep second-degree burn wounds more effectively than hydrogels alone or direct administration of CLD-hFGF2.
