GHK-Cu Peptide for Skin Repair Anti-Aging Collagen Production and Tissue Regeneration

1. Description

GHK-Cu is a natural complex formed by the tripeptide glycyl-L-histidyl-L-lysine chelated with copper ions. It was first discovered in human plasma in 1973, and its concentration decreases with age. It appears as a light blue to blue solid powder and is soluble in dimethyl sulfoxide and water. This compound exerts biological effects by regulating the expression of approximately one-third of human genes. It promotes the synthesis of collagen, elastin, and glycosaminoglycans, while also activating the antioxidant enzyme system and modulating matrix metalloproteinase activity. Storage conditions require refrigeration at 2–8°C under an inert gas atmosphere; in powder form, it can be stored for up to 2 years at –20°C.

2. Application

(1) Skin Care and Anti-Aging Research: Development of functional skincare products designed to firm the skin, reduce wrinkles, and improve skin elasticity and density; these can be incorporated into products such as face creams, serums, eye creams, and face masks.

(2) Wound Healing Research: Research aimed at promoting re-epithelialization and tissue repair in acute skin wounds; topical application of gel formulations can accelerate the healing process.

(3) Hair Care Research: Development of hair care products designed to stimulate hair growth, increase hair thickness, and enlarge hair follicle size.

(4) Inflammatory Bowel Disease Research: Used in experimental colitis models to investigate the mechanisms underlying inflammation reduction and mucosal repair, involving the regulation of the SIRT1/STAT3 signaling pathway.

(5) Basic Research Applications: Serves as a key tool in tissue repair and anti-aging research, applied in fields such as extracellular matrix remodeling, antioxidant defense mechanisms, and gene expression regulation.

3. Main Efficacy

(1) Anti-aging and Skin Regeneration: Stimulates the synthesis of Type I collagen, elastin, and glycosaminoglycans, firming sagging skin, reducing the depth of fine lines and wrinkles, and improving skin elasticity and firmness. Clinical studies show that after three months of using products containing GHK-Cu, skin collagen density increases by an average of 28%.

(2) Promotes Wound Healing: Accelerates wound closure and tissue regeneration, regulates the activity of matrix metalloproteinases and their inhibitors, and optimizes the tissue remodeling process. Improves blood supply and nerve innervation in damaged tissues by stimulating angiogenesis and nerve outgrowth.

(3) Antioxidant and Anti-inflammatory Effects: Activates antioxidant enzymes such as superoxide dismutase to scavenge free radicals and peroxides, protecting skin cells from oxidative damage. Inhibits the production of major inflammatory factors such as tumor necrosis factor-α and interleukin-6, thereby exerting anti-inflammatory effects.

(4) DNA Repair and Cell Protection: Activates DNA repair mechanisms and promotes the clearance of damaged proteins by enhancing proteasome function, thereby protecting cellular function.

(5) Promotes Hair Growth: In hair care applications, it stimulates hair follicle activity, increases hair thickness and follicle size, and improves overall hair health.
