    TLDR Fish scale collagen peptide speeds up wound healing effectively.
    This study investigated the efficacy of fish scale collagen peptide (FSCP) in promoting wound healing in a mouse model with full-thickness skin injuries, using gavage and topical administration methods. FSCP and its fractions significantly accelerated wound healing by shortening scab-shedding time, increasing granulation tissue, hair follicle, and capillary production, and enhancing collagen remodeling. The most effective FSCP fractions were those smaller than 1 kDa, achieving wound healing rates of 99.66% and 99.63% for gavage and topical administration, respectively. The study also identified bioactive peptides, such as APDPFR, GTPIQF, and TPIQF, with potential therapeutic benefits, highlighting FSCP's value in clinical wound treatment.
