GHK-Cu is a naturally occurring copper-binding tripeptide (Gly-His-Lys) widely studied for its role in skin regeneration, wound healing, and hair and tissue repair. It is often used in cosmetic and regenerative protocols to improve firmness, elasticity, and overall skin “glow.”

Peptide overview

GHK-Cu is formed when the small peptide GHK chelates a copper ion, creating a complex that signals cells to remodel and repair tissue. Research shows this peptide appears in human plasma, saliva, and urine and declines with age, paralleling reduced regenerative capacity. It is frequently featured in modern “glow” and “klow” protocols focused on skin quality and healthy aging.

Research benefits

• Supports collagen, elastin, and glycosaminoglycan production, contributing to firmer, smoother, and more youthful-looking skin.

• Enhances wound healing and tissue remodeling, improving repair of damaged skin and supporting post-procedure recovery.

• Exhibits antioxidant and anti-inflammatory actions, helping protect cells from oxidative stress and environmental damage.

• Commonly used in protocols targeting hair density and scalp health, alongside its role in overall skin rejuvenation.
