# GHK-Cu papers and reviews

> peptide body lotion: collected studies — The peptide body lotion reading list: published GHK-Cu work on collagen synthesis, tissue remodelling, human-skin copper delivery and topical creams.

**Reading list**

The culture dish, the skin preparation and the cream each contribute a different kind of result.

## Collagen and tissue remodelling

The [fibroblast-culture experiment](https://pubmed.ncbi.nlm.nih.gov/3169264/) supplies the finding that first earned the peptide my serious attention: stimulated collagen synthesis without a change in cell number. The [tissue-remodelling review](https://pubmed.ncbi.nlm.nih.gov/18644225/) places collagen alongside other repair-related processes across human and animal work.

## Skin passage and topical results

The [human-skin penetration paper](https://pmc.ncbi.nlm.nih.gov/articles/PMC3016279/) reports copper passage and retention in skin outside the body. For the topical outcomes, there is the [skin-regeneration review](https://pmc.ncbi.nlm.nih.gov/articles/PMC4508379/), followed by the [review focused on topical GHK and delivery problems](https://pmc.ncbi.nlm.nih.gov/articles/PMC11830136/). The latter earns its place here by bringing the formulation back into the discussion.
