An Evaluation of Collagen Peptide for Transdermal Delivery Using Strat-M Membrane and Excised Mouse Skin

This study found that oral collagen peptides increased expression of genes associated with epidermis development and the hair cycle in hairless mice, providing insights into their potential skin benefits.

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 found that oral collagen peptides increased the expression of genes related to epidermal and hair cycle development in hairless mouse skin.

This study discusses the effects of collagen hydrolysates and the dipeptide Pro-Hyp on gene expression related to hair and epidermis development in mouse skin and reports no new clinical results.

This study found that a new transdermal drug delivery system using globefish skin collagen peptides and dissolving microneedles effectively promoted hair regrowth in mice with androgenetic alopecia by reducing inflammation and enhancing vascularization.
