GHK-Cu

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper peptide found in human plasma, saliva, and urine. Discovered in 1973, it functions as a potent regenerative and signalling molecule in the body, stimulating wound healing, increasing collagen production, and reducing inflammation.

Because plasma levels of GHK-Cu decline significantly as we age — dropping by about 60% by age 60 — it has become a highly popular ingredient in skincare, anti-ageing, and wellness therapies.

Key Benefits

• Skin Rejuvenation: It stimulates fibroblasts to produce collagen and elastin, helping to reduce fine lines, improve skin firmness, and repair protective skin barrier proteins.
• Hair Growth: GHK-Cu is often used in scalp serums to stimulate hair follicle size, improve thickness, and prolong the growth phase of hair.
• Wound Healing: It accelerates tissue repair and reduces inflammation, making it a common post-procedure treatment after microneedling or laser therapies.
• Gene Regulation: Research suggests GHK-Cu can modulate the expression of approximately 4,000 human genes, essentially signalling cells to return to a healthier, more youthful state.

How It Is Used

• Topical (Skincare/Haircare): Widely available in creams, serums, and scalp solutions. This is the most regulated and common method of use.
• Injectable: Sometimes used in anti-ageing and regenerative medicine protocols. Injectable peptides are often sourced from compounding pharmacies and require professional guidance on dosing and safety.
