The Science
Multi-Pathway Skin Renewal
GHK is a tripeptide naturally found in human plasma that drops roughly 60% between age 20 and 60. Bound to copper, it becomes a powerful signaling molecule that triggers your fibroblasts to rebuild the dermis the way they did in your 20s.
Copper Delivery
GHK binds copper at physiological pH and delivers it to cells where lysyl oxidase uses it to cross-link new collagen.
Fibroblast Activation
Upregulates over 4,000 genes including collagen, elastin, and decorin synthesis, the structural foundation of skin.
Anti-Inflammatory
Reduces inflammatory gene expression (TNF-α, IL-6, NF-κB) so wounds close faster and inflammation-driven aging slows down.
Applications
Common Use Cases
Anti-Aging Skin Renewal
Fine lines, sagging, loss of elasticity, sun damage, and uneven skin tone.
Wound and Scar Repair
Post-procedure healing, scar fading, and accelerated tissue repair after cuts or burns.
Hair Density Support
Scalp microinjection or topical application for thinning hair and follicle health.
Post-Procedure Recovery
After microneedling, laser resurfacing, surgery, or aggressive skincare protocols.

Your protocol timeline
What to expect, week by week
Weeks 1-2
Daily subcutaneous dosing begins. Faster healing of small wounds and reduced redness are the first signs the protocol is working.
Weeks 3-4
Skin texture starts to improve. Many report a slightly tighter, smoother feel and more even tone.
Weeks 6-8
Fine lines soften and scar appearance begins to fade as fibroblasts rebuild collagen and elastin.
Weeks 8-12
Deeper structural changes. Cycle off for 2-4 weeks, then reorder to extend results if continuing.
