Biopeptides, particularly those derived from collagen and other extracellular matrix proteins, have been scientifically investigated for their role in supporting wound healing and the treatment of cuts. Peptides are short chains of amino acids that can serve as signaling molecules within the skin. Several studies have demonstrated that certain bioactive peptides can stimulate the proliferation and migration of fibroblasts and keratinocytes, which are essential cell types in the wound healing process. Additionally, some peptides have been shown to enhance collagen synthesis and modulate inflammation, contributing to faster and more effective tissue repair.

For example, synthetic peptides such as palmitoyl pentapeptide-4 or copper tripeptide-1 (GHK-Cu) have been evaluated in preclinical and some clinical studies for their potential to accelerate wound closure, reduce scar formation, and improve the structural integrity of healing skin. These peptides are believed to work by mimicking natural signaling molecules that regulate skin repair and regeneration.

While the body of evidence is promising, most studies are small or preclinical, and rigorous, large-scale human trials are limited. Thus, the scientific validation of biopeptides for treating cuts is moderate, with a growing base of experimental support but not yet robust, high-level clinical consensus.
