About this trial
This study will evaluate whether a topical gel containing GHK-Cu (a copper(II)-peptide complex) can safely speed up healing of small, standardized skin wounds in healthy adults compared with a matching vehicle gel.
Participants will receive two small punch-biopsy wounds on the upper arm; each wound will be randomly assigned to receive GHK-Cu gel or vehicle gel under identical dressings. Wounds will be photographed and assessed over 3 weeks, with a follow-up visit to evaluate scar quality.
