The advanced copper peptide supporting smoother, firmer and healthier-looking skin.
Copper Tripeptide-1 may appear in a skincare formula at a very small concentration, but that does not make it insignificant.
This highly specialised peptide is valued for its ability to support the natural processes associated with skin renewal, resilience and a smoother-looking complexion. It is particularly well suited to formulas created for visible signs of ageing, including fine lines, loss of firmness and reduced elasticity.
But what exactly is a copper peptide—and why is only a tiny amount needed?
What Is Copper Tripeptide-1?
Copper Tripeptide-1 is a small peptide made from three amino acids joined to a copper ion.
It is also commonly associated with the name GHK-Cu. GHK refers to the three amino acids that form the peptide:
- Glycine
- Histidine
- Lysine
Copper is a naturally occurring trace mineral that plays an important role in numerous biological processes. When it is bound to this particular peptide, it forms a specialised copper-peptide complex used in advanced skincare formulations.
On an ingredient list, it appears by its official cosmetic ingredient name: Copper Tripeptide-1.
Is Copper Tripeptide-1 the Same as Ordinary Copper?
No. Copper Tripeptide-1 is not simply metallic copper or a loose copper mineral added to skincare.
In this ingredient, a copper ion is bound to a specific three-amino-acid peptide. The peptide acts as a carrier, creating a recognised complex with its own skincare applications.
This distinction matters because the performance of an ingredient is determined by its complete structure—not merely by the presence of copper.
Similarly, the inclusion of Malachite Extract in the Re-Gen formula does not replace Copper Tripeptide-1. Although both ingredients have a connection to copper, they perform different and complementary roles within the serum.
How Does Copper Tripeptide-1 Work in Skincare?
Copper Tripeptide-1 is often described as a carrier peptide. Carrier peptides bind to and carry trace elements, such as copper, within a formulation.
Research into GHK-Cu has explored its relationship with processes involved in skin conditioning, renewal and the maintenance of the skin’s extracellular matrix—the supportive network surrounding skin cells.
In cosmetic skincare, Copper Tripeptide-1 is used to help support:
- Firmer and more resilient-looking skin
- A smoother skin surface
- The appearance of improved elasticity
- Healthy-looking skin renewal
- The softening of visible fine lines
- Overall skin vitality
It is important to remember that skincare products work on the appearance and condition of the skin. Copper Tripeptide-1 is not a medical treatment and cannot permanently reverse the natural ageing process.
Its value lies in providing targeted, ongoing support within a carefully balanced skincare routine.
Why Is Copper Tripeptide-1 Used in Such a Small Amount?
The Re-Gen Peptide Power Serum contains 0.005% Copper Tripeptide-1.
This may look like a small percentage when compared with ingredients such as Niacinamide or Vitamin C, but peptides are highly specialised molecules designed to be used at precise concentrations.
Skincare percentages cannot be compared without considering the type of ingredient involved. Some ingredients need to make up a relatively large part of a formula to perform their function, while others are used at very low, targeted levels.
More is not automatically better.
The appropriate amount depends on:
- The identity and structure of the peptide
- Its intended function
- The supplier’s technical specifications
- How it interacts with the rest of the formulation
- The texture, stability and intended use of the finished product
This is why we do not add the percentages of different peptides together and present them as one combined “peptide percentage”. Reneseed™ and Copper Tripeptide-1 are distinct technologies used at different concentrations for different purposes.
What Can Copper Tripeptide-1 Do for the Skin?
When incorporated into a well-formulated product and used consistently, Copper Tripeptide-1 can help support:
Firmer-looking skin
The skin naturally becomes less firm and resilient with age. Copper Tripeptide-1 is used in formulations designed to support the structures associated with a firmer-looking complexion.
Smoother-looking texture
By supporting the skin’s overall condition and renewal processes, it can contribute to a softer, smoother-looking skin surface.
The appearance of fine lines
Consistent use may help soften the visible appearance of fine lines and wrinkles as part of a complete age-supporting routine.
Skin resilience
Copper peptides are valued for helping support skin that looks healthier, stronger and better able to cope with the visible effects of everyday environmental stress.
Overall skin vitality
Skin can begin to look tired or less vibrant over time. Copper Tripeptide-1 supports a more renewed and healthy-looking complexion.
Results are gradual rather than immediate. Regular use over time is more important than expecting an overnight transformation.
Who Would Benefit Most?
Copper Tripeptide-1 may be especially useful for skin that:
- Is showing visible fine lines and wrinkles
- Feels less firm or elastic
- Looks tired, dull or less resilient
- Is experiencing age-related changes
- Would benefit from gentle, ongoing renewal support
- Cannot comfortably tolerate stronger age-supporting actives
It can be used by different skin types, including dry, combination and sensitive skin, provided the complete formulation is suitable for the individual.
As with any new skincare product, patch testing is advisable if your skin is particularly reactive.
When Should You Start Using Copper Peptides?
There is no fixed age at which Copper Tripeptide-1 must be introduced.
Some people begin using peptide skincare when they first notice changes in texture, firmness or elasticity. Others introduce it later when visible signs of ageing have become more established.
Peptides can form part of either a preventative or corrective-looking skincare routine. The most important consideration is whether the product addresses your present skin concerns and works comfortably with the rest of your routine.
Can Copper Tripeptide-1 Be Used With Vitamin C?
Yes. The Re-Gen Peptide Power Serum can be used within the same overall routine as our Glow Getter Vitamin C Serum.
If you prefer to keep your routine simple, use Vitamin C in the morning and Re-Gen in the evening. You can also layer them if your skin tolerates both products comfortably.
When layering, apply the lighter water-based serum first and allow it to absorb before applying the next product.
There is no need to avoid peptides simply because you use Vitamin C. Modern skincare formulas contain stable, carefully selected ingredients, and the performance of the finished formulation matters more than broad ingredient-pairing rules found online.
What Can You Use With Copper Tripeptide-1?
Copper Tripeptide-1 generally fits comfortably into a well-rounded routine and may be used alongside:
- Hyaluronic Acid
- Niacinamide
- Vitamin C
- Squalane
- Botanical antioxidants
- Moisturisers
- Facial oils
When introducing several active products, add them gradually rather than starting everything at once. This makes it easier to see how your skin responds and helps avoid an unnecessarily complicated routine.
How Do You Use It?
Copper Tripeptide-1 is included in our lightweight, water-based Re-Gen Peptide Power Serum.
After cleansing and toning, apply a few drops to the face, neck and décolletage. Gently smooth the serum over the skin and allow it to absorb before applying moisturiser or facial oil.
Re-Gen is fragrance-free and suitable for morning or evening use.
During the day, always finish with a broad-spectrum sunscreen.
💡 Myth vs Fact
Myth: A peptide used at 0.005% is too weak to matter.
Fact: Different skincare ingredients work at very different concentrations. Copper Tripeptide-1 is a specialised peptide designed for use at a precise, targeted level. Its percentage should not be compared directly with ingredients such as Vitamin C, Niacinamide or Hyaluronic Acid.
Myth: Copper Tripeptide-1 and Malachite Extract are the same ingredient.
Fact: They are completely different ingredients. Copper Tripeptide-1 is a peptide complex containing three amino acids bound to copper. Malachite Extract is a mineral-derived antioxidant ingredient. They perform complementary roles in the Re-Gen formula.
Myth: Copper peptides instantly rebuild ageing skin.
Fact: No cosmetic product can instantly or permanently reverse skin ageing. Copper Tripeptide-1 is used to support smoother, firmer and healthier-looking skin gradually with consistent use.
Myth: Copper peptides are only for deeply wrinkled skin.
Fact: They can be used when the earliest changes in firmness and texture become visible, as well as in routines designed for more established signs of ageing.
💡 Did You Know?
The “1” in Copper Tripeptide-1 is part of its official INCI name. It does not refer to the ingredient’s percentage in the serum.
The Re-Gen Peptide Power Serum contains Copper Tripeptide-1 at 0.005%, but this percentage appears separately in the product’s formulation documentation—not in the ingredient’s name.

Q: Why did you include Copper Tripeptide-1 in the Re-Gen Peptide Power Serum?
A: We wanted a peptide that could provide targeted support for visible signs of ageing, particularly loss of firmness, reduced elasticity and fine lines. Copper Tripeptide-1 is a highly specialised ingredient used at a precise concentration. We paired it with Reneseed™ to support skin renewal and vitality, and with Malachite Extract to provide complementary antioxidant support.
Why We Paired It With Reneseed™ and Malachite Extract
A good serum is not created by adding one fashionable ingredient to a basic formula. It is created by selecting ingredients that perform distinct but complementary roles.
In the Re-Gen Peptide Power Serum:
- Copper Tripeptide-1 supports firmer, smoother and more resilient-looking skin.
- Reneseed™ Peptide supports skin renewal, vitality and a healthier-looking complexion.
- Malachite Extract provides antioxidant support against everyday environmental stress.
- Glycerin and Pentylene Glycol help attract and retain moisture while contributing to the serum’s lightweight texture.
Together, these ingredients create a balanced formula designed to address several visible signs of ageing without making the routine feel heavy or complicated.
