What the research shows about GHK-Cu (copper tripeptide-1)
GHK-Cu is a naturally occurring copper-binding peptide that has been studied for its role in skin, including cell signaling, the extracellular matrix, and wound healing. Much of the strongest human evidence comes from wound-healing research; its cosmetic use is studied but the topical evidence is still developing. ION BLUE cites this research openly and formulates our GHK-Cu serum at a real, disclosed 0.10% concentration — no proprietary blends, no fillers. We describe what GHK-Cu is studied for, never more than the evidence supports.

Included to provide context for topical cosmetic formulation considerations.
HOW ION BLUE USES RESEARCH
ION BLUE references scientific literature to guide formulation decisions with clarity and restraint. Research is used to inform ingredient selection, concentration philosophy, and cosmetic context — not to make medical claims.
