GHK-Cu
researchCopper peptide for skin rejuvenation, wound healing, hair growth, and anti-aging
Availability in Thailand
GHK-Cu is widely available in Thailand both as injectable vials from peptide vendors and in topical formulations (serums and creams) from skincare retailers. Thai aesthetics clinics frequently incorporate GHK-Cu into anti-aging and skin rejuvenation protocols, and it pairs well with treatments like microneedling.
Prescription: Not required.
Legal status: Available as a research peptide (injectable) and in cosmetic formulations (topical) in Thailand.
Where to Buy in Thailand

Overview
GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper-binding tripeptide found in human blood plasma, saliva, and urine. It is one of the most extensively studied peptides for skin health, with demonstrated effects on collagen synthesis, wound healing, antioxidant defence, and hair follicle stimulation. As a copper carrier, it delivers bioavailable copper to cells, activating numerous regenerative and protective processes.
How It Works
Collagen and elastin synthesis
GHK-Cu stimulates the production of collagen types I, III, and V, as well as elastin — the structural proteins responsible for skin firmness, elasticity, and youthful appearance. It also promotes glycosaminoglycan synthesis, improving skin hydration.
Wound healing acceleration
Promotes the migration and proliferation of fibroblasts and keratinocytes at wound sites. Research shows it speeds wound closure, increases blood vessel formation, and improves the quality of healed tissue.
Antioxidant and anti-inflammatory
GHK-Cu upregulates superoxide dismutase (SOD) and other antioxidant enzymes, protecting cells from oxidative damage. It also suppresses pro-inflammatory cytokines, reducing chronic inflammation that accelerates skin aging.
Hair follicle stimulation
Research suggests GHK-Cu can increase hair follicle size, stimulate hair growth, and extend the growth (anagen) phase of the hair cycle. Studies have shown it increases the expression of genes involved in hair growth and follicle health.
Protocol Quick Reference
Benefits & Uses
- Skin rejuvenation: Stimulates collagen and elastin production for firmer, more elastic skin with reduced fine lines
- Wound and scar healing: Accelerates wound closure and improves the quality of healed tissue with less scarring
- Hair growth support: May stimulate hair follicles, increase follicle size, and extend the growth phase of the hair cycle
- Antioxidant protection: Upregulates the body's natural antioxidant defence systems, protecting cells from UV and environmental damage
- Anti-inflammatory: Reduces chronic low-grade inflammation associated with aging skin
- Dual application routes: Effective both topically (serums, creams) and via injection — different routes for different goals
Side Effects
Common
- Injection site redness or mild irritation
- Mild skin tingling when applied topically (usually indicates absorption)
- Temporary skin flushing
Less Common
- Mild nausea (injection)
- Headache
Serious
- Generally considered very safe with an extensive history of topical use in cosmetics
- Avoid applying to actively infected wounds
- Those with copper metabolism disorders (Wilson's disease) should avoid GHK-Cu
- Long-term injectable safety data is limited

FAQ
Should I use injectable or topical GHK-Cu?▼
Topical is sufficient for surface-level skin improvement — reducing fine lines, improving skin texture, and enhancing wound healing on the skin's surface. Injectable provides systemic effects for more comprehensive anti-aging, hair growth, and deeper tissue benefits. Many people use both.
Can I use GHK-Cu with microneedling?▼
Yes — this is a popular combination in Thai aesthetics clinics. Microneedling creates micro-channels that enhance GHK-Cu penetration into deeper skin layers, and GHK-Cu supports the collagen induction response triggered by microneedling.
Does GHK-Cu help with hair loss?▼
Research suggests it can stimulate hair follicles, increase follicle size, and extend the growth phase. Some users inject it subcutaneously into the scalp for localised hair growth support. Results vary between individuals.
Is GHK-Cu safe for daily topical use?▼
Yes — GHK-Cu has an extensive history of safe use in topical cosmetic formulations. It is widely used in anti-aging serums and creams globally and is generally very well tolerated on the skin.
