GHK-Cu papers let you check what was actually tested

GHK-Cu note numbers point to original study reports

A skin-care promise needs more than impressive words. Each number beside a GHK-Cu finding leads to a paper below. The list gives the authors, year, journal and a link. A journal publishes studies. The long identifying codes help locate the paper. You can follow the skin findings without knowing what those codes mean.

Some reported skin problems don't have a matching study here. You'll see that lack of proof in the answers. We don't use an unrelated paper to make a concern look settled. You can see whether the research tested people or used cells or animals. You can also check what actually changed.

You need a paper supporting the seller's promise, not merely naming GHK-Cu.
