In the research
19 PubMed papers mention it with skin, cosmetics or hair; the three most recent:
- GHK-Cu as a Bioactive Metallopeptide and Drug-Delivery Cargo: Coordination Chemistry, Formulation Science, Therapeutic Evidence, and a Translational Roadmap · Pharmaceutics, 2026
- Water-Soluble, Enzyme-Degradable, and Hydrolyzable STAR Particles for Enhanced Drug Delivery to Skin · Advanced healthcare materials, 2026
- Augmented Skin Beneficial Effects of Thermus Thermophilus and Bacillus Subtilis Mixed-Culture Ferment Extract by Tripeptide GHK-Cu · Skin research and technology : official journal of International Society for Bio, 2026
A paper is a paper, not a verdict: titles are listed so you can read them, and a study on cells or mice says little about a cream on a face.
