GHK-Cu Copper Peptide

GHK-Cu is a tripeptide naturally present in human plasma. It’s released from tissues in response to injury [2]. Because it has a high affinity for copper, GHK-Cu readily forms the GHK-Cu complex. It also ha protective and regenerative properties, making GHK-Cu helpful in skincare and haircare products.

Mechanisms of action of GHK-Cu copper peptide

GHK-Cu copper peptide interacts with the skin through various mechanisms of action, contributing to its potential benefits for skin health. Here are the key insights:

Formation of GHK-Cu complex

GHK-Cu peptide readily forms a complex with copper ions (copper 2+), which is believed to be crucial for its biological activity. This complex is stable and plays a role in the peptide’s functions.

Stimulation of collagen synthesis

GHK-Cu has demonstrated the capacity to induce collagen synthesis, a vital protein responsible for imparting structural resilience to the skin. This phenomenon is instrumental in enhancing skin firmness and elasticity, consequently mitigating the visible signs of skin aging.

Wound healing and tissue regeneration

GHK-Cu has demonstrated the ability to accelerate wound healing and tissue regeneration. It promotes tissue growth, attracts immune cells to the site of injury, and supports the production of new blood vessels.

Antioxidant activity

The GHK peptide has antioxidant properties and can help prevent oxidative stress in the skin. It regulates copper levels and modifies the expression of numerous antioxidant genes, potentially reducing the damaging effects of free radicals.

Skin rejuvenation

GHK-Cu is believed to have skin rejuvenating effects, improving skin texture, tone, and overall skin appearance. It can enhance skin elasticity, brightness, and firmness.

Regulation of gene expression

GHK-Cu has demonstrated the ability to influence the expression of numerous genes, including those associated with antioxidant protection and tissue renovation. These alterations in gene expression play a crucial role in the positive impact GHK-Cu has on skin.

However, it’s essential to acknowledge that while scientific evidence supports GHK-Cu’s mechanisms of action, individual outcomes may differ. 

Ongoing research endeavors aim to provide a more comprehensive understanding of its potential advantages for skin health.


Stability and properties of GHK-Cu peptide

GHK-Cu peptide is highly hydrophilic and stable in water in the pH range of 4.5-7.4 buffers for at least two weeks at 60°C. It is prone to hydrolytic cleavage when subjected to oxidative stressors.

Benefits of GHK-Cu

  • Skin regeneration: GHK-Cu stimulates collagen and glycosaminoglycan synthesis in skin fibroblasts, promoting wound healing and tissue remodeling. It also has antioxidant and anti-inflammatory effects.
  • Hair growth: Copper is one of the micronutrients needed to produce melanin, which is responsible for hair color. GHK-Cu may stimulate hair follicles to receive adequate oxygen and nutrients to produce new hair growth.
  • Gene expression modifier: GHK-Cu has been shown to modify the expression of numerous antioxidant genes. It also stimulates both synthesis and breakdown of proteins.
  • Repair Skin Barrier: GHK-Cu is a copper-based peptide that can help to repair and strengthen the skin’s protective barrier proteins, reducing the risk of inflammation and infection. It is often referred to as a topical tripeptide copper complex.

Side effects of GHK-Cu peptide

GHK-Cu peptide has a favorable safety profile, but there are some potential side effects that should be monitored by a trained provider. The copper component of GHK-Cu can cause copper toxicity if prescribed incorrectly.

Reduction in blood pressure: 

GHK-Cu possesses an anxiolytic effect, which can lead to a reduction in blood pressure levels. However, it’s essential to note that in elevated concentrations, this effect can become potentially hazardous and, in extreme cases, even life-threatening.

Injection site pain: 

The subcutaneous or intramuscular administration of peptides in general is associated with injection site pain, lightheadedness, nausea, and even fainting in test subjects.

Skin irritation and redness: 

GHK-Cu does have potential side effects, which may include skin irritation and redness. To ensure safety, it is crucial to conduct a patch test before applying the product to a larger skin area. 

If needed, other protective skin barrier proteins can be applied. If any adverse reactions occur during use, it’s important to discontinue use promptly.

Monitoring of side effects

To confirm the presence of GHK-Cu in a skincare or hair product, it is crucial to meticulously review the ingredient labels. GHK-Cu should be listed as one of the primary ingredients to ensure its efficacy.

Physicians closely monitor the side effects of GHK-Cu peptide through regular check-ups and blood tests. This vigilance is vital in assessing and mitigating the risk of copper toxicity caused by the copper component.

Choosing High-Quality GHK-Cu Copper Peptide Products

  • Brand and Manufacturer Selection: Prioritize established and reputable brands and manufacturers renowned for their consistent production of high-quality skincare products. A reliable resource for identifying such brands and manufacturers is, a website dedicated to evaluating and endorsing trusted sources.
  • Product Type: GHK-Cu is a versatile ingredient featured in an array of skincare products, ranging from serums to creams and lotions. To make an informed choice, assess your specific skin requirements and opt for a product tailored to your skin type and concerns.

  • Ingredient Scrutiny: Exercise diligence by meticulously reviewing the product’s ingredient list. Ensure GHK-Cu is prominently featured as one of the primary constituents. Furthermore, prioritize products devoid of harmful chemicals and additives, emphasizing safety and efficacy.
  • Research and Consultation: For personalized guidance, contemplate seeking counsel from a qualified dermatologist or skincare expert. Their expertise can be invaluable in selecting the ideal GHK-Cu product tailored to your unique skincare needs.

Overall, it is important to choose high-quality GHK-Cu copper peptide products to ensure their effectiveness and safety. 

By considering the above factors, you can make an informed decision and select a product that is suitable for your skin and needs. 

When you buy GHK cu copper peptide, choose only high quality suppliers like Research Chemical to ensure that your research outcomes are as safe and precise as possible.
