Study data at a glance
- Participants or experimental model
- Safety-evaluation framework and earlier cosmetic studies; no newly recruited GHK cohort.
- Reported results
- The framework discusses modified peptide delivery and summarizes earlier Pal-GHK work. Cosmetic exposure, formulation and industry context matter when interpreting these reports.

Methods, limitations & source review
Study limitations
- Several authors have cosmetic-industry affiliations.
- A topical cosmetic safety framework cannot establish injectable safety or the safety of newly extended GHK peptides.
Publication counts are not counts of independent trials. Reviews, translations and reports sharing participants may overlap. Findings apply to the studied preparation, population and endpoints.
