What is GHK-Cu?

Copper Tripeptide-1 – better known as GHK-Cu, the “blue copper peptide” – is a naturally occurring complex of three amino acids (glycyl-L-histidyl-L-lysine) bound to a copper ion. Present in the body from birth and declining with age, it is one of the most studied regenerative peptides in skin science, and currently the fastest-growing peptide search in skincare.

What GHK-Cu does

• Matrix regeneration – as a signal peptide carrying copper to cellular receptors, GHK-Cu stimulates synthesis of the skin matrix: firmness, elasticity, wrinkle reduction.
• Repair and scars – documented support of wound healing and scar-quality improvement.
• Hair growth – GHK-Cu enlarges hair follicles and supports growth, which is why it appears in serious hair-loss protocols.
• Calming and protection – inhibits IL-6 and quenches reactive carbonyl species involved in UV damage.

Fusion Meso formulations with GHK-Cu

• F-HA LIFT – high-weight hyaluronic acid skin booster where copper tripeptide-1 joins NCTC 135 and sodium succinate for revitalising, firming protocols.
• F-HAIR MEN – copper tripeptide-1 in the androgenic hair-loss protocol, alongside peptides and growth factors.

GHK-Cu in professional protocols

Delivered through sterile vials during mesotherapy or micro-needling sessions, GHK-Cu reaches the skin at the moment it is most receptive to regeneration signals. Clinics then extend the stimulus with peptide home care between sessions.

Frequently asked questions

Why is GHK-Cu blue?

The characteristic blue colour comes from the copper ion complexed within the peptide – the same copper the peptide delivers to skin enzymes involved in repair.

Can GHK-Cu be combined with vitamin C or retinol?

In professional routines they are usually scheduled at different times of day or alternating days, to preserve the copper-peptide complex – your practitioner will sequence the protocol.
