BEAUTY PEPTIDE GHK-Cu/Copper Tripeptide-1 Anti-Aging COSMETICS API

Product Description

GHK-Cu (CAS No. 89030-95-5, INCI name: Copper Tripeptide-1) is a natural small-molecule peptide complex formed by the chelation of the glycine-histidine-lysine tripeptide (GHK) with copper ions in a 1:1 ratio. It was first isolated from human plasma in 1973 by American scientist Loren Pickart. It occurs naturally in blood, saliva, and skin tissue, and is currently the most extensively studied and widely used active copper peptide ingredient worldwide.

Structurally, the uniqueness of GHK-Cu lies in its dual role as a “peptide chain carrier + copper ion”: the imidazole ring of histidine forms a stable chelate structure with the copper ion. On the one hand, it acts as a safe transport carrier for copper ions, precisely delivering this trace element—which is essential for the human body but difficult to utilize in its free state—into cells, thereby preventing oxidative damage caused by free copper; on the other hand, the GHK tripeptide itself acts as a signaling peptide, capable of directly interacting with target cells—such as skin fibroblasts—to regulate gene expression. The concentration of GHK in human plasma decreases significantly with age (approximately 200 ng/mL at age 20, dropping to about 80 ng/mL by age 60); this finding has made it a key subject of research in the fields of aging and tissue repair.

The product appears as a light blue to blue-violet powder; its aqueous solution exhibits a characteristic pale blue color. It is readily soluble in water and buffered solutions, with HPLC-determined purity exceeding 98%. As a globally compliant cosmetic ingredient and active peptide for research purposes, GHK-Cu is supported by numerous human clinical and in vitro study data, making it a representative ingredient in the fields of anti-aging skincare, wound healing, and regenerative medicine.

Key Benefits

The core benefits of GHK-Cu can be summarized as a dual-action approach of “promoting repair and combating aging.” On the one hand, through its role as a carrier that chelates copper ions, it releases copper within cells and activates key enzyme systems such as lysyl oxidase (which promotes collagen and elastin cross-linking) and superoxide dismutase (which provides antioxidant protection); on the other hand, as a signaling peptide, it regulates the expression of over 4,000 genes in the human body, comprehensively resetting the cellular state toward “repair and rejuvenation”—upregulating genes related to collagen synthesis, antioxidant defense, and DNA repair, while downregulating genes associated with inflammation and matrix degradation. At the skin and tissue level, this manifests as multiple benefits, including promoting collagen production, providing antioxidant and anti-inflammatory effects, and accelerating wound healing and barrier repair. Key benefits include:

1. Promotes collagen and elastin synthesis, firming the skin and reducing wrinkles: Activates fibroblasts to promote the production of Type I and Type III collagen and elastin (in vitro studies show collagen synthesis can increase by approximately 70%), and multiple human trials have confirmed that continuous use increases skin density and thickness while improving fine lines and sagging.

2. Powerful antioxidant properties: As a superoxide dismutase (SOD) mimetic, it scavenges free radicals and activates the endogenous antioxidant system; its ORAC antioxidant value is approximately three times that of vitamin C, helping to defend against photoaging damage caused by UV rays and environmental pollution.

3. Anti-inflammatory and Soothing: It inhibits the NF-κB inflammatory pathway and downregulates pro-inflammatory factors such as TNF-α, IL-6, and IL-1β, providing a soothing effect on redness in sensitive skin, inflammatory acne, and post-surgical redness and swelling.

4. Promotes Wound Healing and Tissue Repair: Accelerates the migration of keratinocytes and fibroblasts, promotes angiogenesis, and regulates the balance between matrix degradation and reconstruction. Animal and clinical studies have shown that it shortens wound healing time and reduces scar hyperplasia.

5. Repairs the skin barrier: Upregulates the expression of barrier-related proteins such as tight junction proteins, significantly reduces transepidermal water loss (TEWL), and improves conditions of dryness, sensitivity, and barrier damage.

6. Improves hair health (research stage): Promotes the proliferation of dermal papilla cells in hair follicles and extends the anagen phase; continuous use in clinical trials has been shown to increase hair density.

Applications

GHK-Cu is primarily used in the cosmetics and skincare industries—it is one of the first active peptides to be industrially applied. Known by its INCI name, Copper Tripeptide-1, it is widely used worldwide in high-end anti-aging and restorative skincare products. At the same time, its wound-healing and tissue-repair properties are increasingly being applied to medical dressings, wound care, tissue engineering, and regenerative medicine research. Specific applications include:

1. Anti-aging skincare products: serums, face creams, eye creams, neck creams, etc., targeting fine lines, wrinkles, sagging skin, photoaging, and dull complexion (recommended cosmetic concentration: approximately 0.05%–0.5%).

2. Post-aesthetic procedure repair: Wound repair and soothing/calming after procedures such as fractional laser, microneedling, and chemical peels, which can shorten healing time and reduce the risk of post-inflammatory hyperpigmentation.

3. Sensitive skin and barrier repair care: Soothing and repairing conditions such as sensitive skin, corticosteroid-dependent dermatitis, and redness, dryness, and itching caused by a compromised skin barrier.

4. Wound and Scar Care: Research on the repair of chronic wounds such as burns, traumatic injuries, post-surgical wounds, and diabetic foot ulcers, for use in repair gels, medical dressings, and other products.

5. Hair Care Products: Anti-hair loss and hair growth serums, as well as scalp care products, designed to improve the hair follicle environment and thicken hair strands.

6. Research and Regenerative Medicine: As classic research tools in the study of aging biology, tissue repair, and skin regeneration mechanisms, these peptides are also used as functional components in cutting-edge applications such as tissue engineering scaffolds and hydrogel dressings.
