GHK-Cu (Copper Peptide — Skin & Hair)
Precision signaling for healing, performance & longevity
GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper peptide found in human plasma, saliva, and urine — levels decline significantly with age. It is one of the most researched peptides for skin health, wound healing, and hair restoration, with over 50 years of clinical study. GHK-Cu activates over 4,000 genes involved in tissue remodeling, collagen and elastin synthesis, antioxidant defense, and anti-inflammatory signaling — making it a broadly regenerative molecule with particular affinity for skin and hair follicle tissue.
How it works
GHK-Cu binds to cellular receptors and activates a gene expression cascade that upregulates collagen types I, III, and IV; elastin; and proteoglycans — the structural proteins that give skin its firmness and elasticity. It simultaneously downregulates genes associated with inflammation and tissue degradation (MMPs). In hair follicles, it stimulates follicle enlargement, prolongs the anagen (growth) phase, and improves scalp circulation. Administered via subcutaneous injection, topical compounded formulation, or as part of a mesotherapy protocol.
Who is it for?
Patients wanting to improve skin quality, firmness, and elasticity from within; those experiencing hair thinning; patients with chronic wounds or poor tissue healing; anyone wanting to complement aesthetic treatments (Potenza, microneedling) with systemic collagen support; patients interested in evidence-based anti-aging.
Who is it not for?
Wilson's disease (copper metabolism disorder); pregnancy (discuss with provider); allergy to copper compounds.

How is injectable GHK-Cu different from topical copper peptide skincare?
Topical copper peptides have limited skin penetration — they work on the surface but cannot reach the deeper dermal layers where structural collagen is produced. Injectable or mesotherapy GHK-Cu delivers the peptide directly to the dermis at concentrations that topical products cannot achieve, producing measurably greater effects on collagen synthesis and tissue remodeling.
Can GHK-Cu be combined with hair PRP?
Yes — GHK-Cu and scalp PRP work through complementary mechanisms. PRP delivers platelet growth factors that stimulate follicle activity; GHK-Cu enhances follicle enlargement and extends the growth phase at the gene expression level. The combination produces stronger hair restoration results than either alone.
Can I use GHK-Cu alongside Potenza or microneedling?
Yes — and this is an excellent combination. Applied immediately after Potenza or microneedling, GHK-Cu penetrates through the open micro-channels directly into the dermis, amplifying the collagen response significantly. It also accelerates post-treatment healing and reduces recovery time.
