Within the first two weeks, the peptides boosted levels of bFGF, a growth factor that helps skin cells multiply and repair the wound.

The peptides increased levels of a growth factor (TGF-β1) in the skin wounds after two weeks, which helps in tissue repair and collagen production.

After two weeks, the skin wounds of rats given the peptides had more collagen, which is the main structural protein needed for strong healing.

The peptides helped form more blood vessels in the skin wounds of rats within a week, which is important for delivering nutrients to heal the wound.

Rats given a specific dose of salmon collagen peptides after C-section surgery healed faster with stronger skin wounds compared to rats not given the peptides.

Rats given the peptides had more hydroxyproline in their skin wounds, which is a key component of collagen and helps in tissue repair.
