GHK-Cu 0.5%
GHK-Cu 0.5% is used in prescriber-directed longevity, peptide, antioxidant, or skin-longevity protocols. Published evidence varies substantially by ingredient, so the page avoids unsupported disease-treatment claims.
GHK-Cu 0.5% is a compounded topical preparation containing glycyl-L-histidyl-L-lysine copper complex (GHK-Cu) — a naturally occurring human tripeptide that chelates copper(II) ions — at 0.5% concentration in a suitable vehicle. GHK-Cu exerts broad regenerative, anti-inflammatory, and antioxidant effects in skin through multi-pathway gene modulation, stimulating collagen and elastin synthesis, promoting wound healing, and supporting the skin's extracellular matrix. Genesis Compounding prepares this as a prescription-only, patient-specific 503A compounded topical preparation, not FDA-approved as a compounded product.
| Active Ingredient | Pharmacologic Role |
|---|---|
| GHK-Cu 0.5% | Copper-chelating tripeptide that modulates gene expression across multiple regenerative pathways, stimulating collagen I, elastin, glycosaminoglycan, and dermal fibroblast activity while exerting anti-inflammatory and antioxidant effects via reduction of NF-κB, IL-6, and TNF-α signaling. |
Route: Topical application to affected skin areas.
Apply a thin layer to the target area (face, scalp, body, or wound area) once or twice daily as directed by the prescriber. Gently massage into clean, dry skin. Avoid simultaneous use with strong alpha-hydroxy acids, high-concentration vitamin C (ascorbic acid), or retinol in the same application session, as these may interfere with copper peptide stability or cause irritation. May be used post-procedure (after microneedling, laser, or chemical peel) as directed, once skin is no longer broken or actively bleeding.
All dosing is prescriber-determined based on the clinical indication and patient assessment. General application guidance:
- Cosmetic/anti-aging applications: Apply once to twice daily for a minimum of 8–12 weeks to assess response; maximum benefit in collagen remodeling may develop over 3–6 months of consistent use.
- Post-procedure or wound support: Apply as directed by the prescribing clinician, frequency adjusted to the healing phase.
- Duration of ongoing use is determined by clinical response and prescriber judgment.
- GHK-Cu: GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) that chelates copper(II), enabling safe bioavailable copper delivery to cells while preventing free radical activity from unbound ionic copper. GHK modulates the expression of approximately 31% of human genes by ≥50%, upregulating genes involved in collagen I, III, elastin, glycosaminoglycan, and decorin synthesis, and downregulating matrix metalloproteinases (MMPs) that degrade extracellular matrix. GHK-Cu stimulates dermal fibroblast proliferation and increases integrin and p63 expression in epidermal basal cells, supporting stemness. It reduces inflammatory cytokines (IL-6, TNF-α) by blocking NF-κB and p38 MAPK activation, and inactivates lipid peroxidation by-products including 4-hydroxynonenal and malondialdehyde. In wound healing, it promotes angiogenesis through VEGF- and FGF-2-like pathways, attracts repair cells to injury sites, and modulates MMP/TIMP balance for balanced collagen remodeling rather than excessive fibrosis.
Clinical Context: GHK-Cu topical preparations are used in prescriber-directed cosmetic dermatology and wound care contexts for their well-characterized regenerative and anti-inflammatory properties. Published evidence supports application in:
- Photoaged/aging skin: Improvement in collagen density, skin firmness and elasticity, reduction in fine lines and wrinkles, and improvement in skin tone and mottled hyperpigmentation after 12 weeks of use.
- Post-procedure recovery: Accelerated wound healing after laser resurfacing, microneedling, chemical peels, and dermabrasion; supports epithelialization and reduces post-inflammatory erythema.
- Wound healing support: Enhanced wound closure and reduced scar formation; studied in diabetic and ischemic wound models.
Monitoring Considerations:
- Response in anti-aging applications typically appears at 4–8 weeks; structural collagen improvements may take 3–6 months.
- Monitor for local irritation (rare); if redness or irritation persists, reassess vehicle and concurrent skincare ingredients.
- GHK-Cu is generally well tolerated; no documented systemic toxicity at cosmetic topical concentrations.
Contraindications:
- Known hypersensitivity to GHK-Cu, copper compounds, or any vehicle excipient.
- Application to infected open wounds or active skin infection sites until infection is treated.
Warnings & Precautions:
- Avoid concurrent use with strong oxidizing agents (high-concentration vitamin C, strong AHAs, retinol) in the same application session as they may destabilize the copper-peptide complex or cause irritation.
- GHK-Cu has been used in cosmetic preparations for decades without documented systemic toxicity; however, data from large-scale clinical trials in prescription populations are limited.
- For post-procedure use, do not apply to open wounds or immediately post-ablative procedure; allow partial barrier recovery before initiating.
Drug Interactions:
- No clinically established systemic drug interactions documented for topical GHK-Cu at standard cosmetic concentrations.
- Topical copper chelators or metal-binding compounds may theoretically compete with GHK-Cu for binding.
Common Side Effects: Transient local redness, mild tingling, or irritation at application site — typically minimal and resolving quickly. Systemic adverse effects have not been reported at topical cosmetic concentrations in published literature.
Store at controlled room temperature (20–25°C / 68–77°F). Protect from light, heat, and air exposure (keep container tightly closed). Do not freeze. Keep out of reach of children. As a 503A compounded preparation, use before the beyond-use date (BUD) printed on the Genesis Compounding prescription label.
What is GHK-Cu and why is it used in skin care?
GHK-Cu (glycyl-L-histidyl-L-lysine:copper) is a naturally occurring tripeptide found in human plasma that plays a key role in tissue repair and regeneration. It stimulates collagen and elastin synthesis, promotes wound healing, reduces inflammation, and acts as an antioxidant — making it one of the most well-studied peptides in regenerative dermatology.
Can I use this with my other skincare products?
Avoid using GHK-Cu in the same application session as high-concentration vitamin C (ascorbic acid), retinol, or strong alpha-hydroxy acids, as these can destabilize copper peptides or cause irritation. Apply at different times of day. Your prescriber can advise on the best regimen.
How long before I see results?
Initial improvements in skin texture and tone may be noticed within 4–8 weeks of consistent daily use. Structural changes in collagen density and skin firmness typically develop over 3–6 months. Post-procedure wound healing support is generally apparent within the healing timeline of the underlying procedure.
Is this FDA-approved?
GHK-Cu 0.5% topical is a 503A compounded preparation prepared by Genesis Compounding for individual patient use per prescriber direction. It is not an FDA-approved drug product. GHK-Cu has an extensive safety record in cosmetic applications but has not been reviewed by the FDA as a compounded preparation.
Can this be used after procedures like microneedling or laser?
Yes, GHK-Cu is frequently used in post-procedure protocols to support skin recovery. Your prescriber will specify when to begin application based on the procedure performed and your healing progress. Do not apply to broken skin immediately post-ablative treatment.
