RadianceGHK-Cu
The copper peptide your skin has been losing since your twenties.
About
What it is
GHK-Cu is a naturally occurring copper peptide that signals cells to produce collagen, repair tissue, and regenerate. Your body makes less of it every year after 20. We give you more.
How it works
GHK-Cu binds to copper ions and activates genes involved in collagen synthesis, skin remodeling, and tissue regeneration. It increases the production of decorin, which regulates collagen assembly and keeps skin firm and structured.

Safety & tolerability
GHK-Cu occurs naturally in human blood plasma and declines with age. It has been used in skincare formulations for decades with an established tolerability profile.

Your care team reviews your profile, monitors your protocol, and is available for questions throughout.
