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.

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

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 healed their skin wounds about a day or two faster than those not given the peptides.

At one week, the peptides increased CD31, a marker for blood vessels, helping to form new vessels in the wound area.

Higher doses of the peptides led to stronger skin and uterine wounds, with the highest dose showing the best results.
