Skin & hair regeneration.
Topical and dermal-route research on copper-peptide and short-peptide cosmetic-application studies. RCT-grade evidence available for a subset.
§ About this topic
Skin and hair regeneration covers topical short-peptide and copper-peptide research, including dermal-route studies on collagen, elastin, and barrier function. This is the area with the cleanest topical-route evidence — the Gruenwald 2024 RCT and the Dou 2020 review provide solid mechanism work, and the cosmetic-route framing keeps the evidence applicable. Injectable-route framing is not consumer-pathway substantiated and isn't covered editorially in this cluster.
