Peptide-based skincare products have become extremely popular in recent years, especially those that combine multiple peptide technologies in one formula. One product that often comes up in skincare discussions is The Ordinary Multi-Peptide Serum. Many people researching peptide skincare ask an important question:
Does The Ordinary peptide serum contain GHK-Cu (copper peptide)?
The answer depends on which version of the serum you are referring to, because The Ordinary offers more than one peptide formula. Below is a clear breakdown of whether GHK-Cu is included, what it does, and how the ingredient works in peptide serums.
What Is GHK-Cu?
GHK-Cu, also known as Copper Tripeptide-1, is a small peptide made from three amino acids bound to copper. This compound occurs naturally in the human body and has been widely studied for its potential role in skin repair and regeneration.
In skincare formulations, GHK-Cu is commonly used for its ability to support skin health through several mechanisms, including:
- Supporting collagen production
- Improving skin elasticity
- Helping reduce visible wrinkles
- Supporting skin repair processes
Research suggests that copper peptides may stimulate the production of collagen, elastin, and other skin-supporting molecules that help maintain youthful skin structure.
Because of these benefits, GHK-Cu is frequently included in anti-aging skincare formulas and peptide serums.
Does The Ordinary Multi-Peptide Serum Contain GHK-Cu?
The answer depends on the specific formula.
1. Multi-Peptide + HA Serum
The standard Multi-Peptide + HA Serum (formerly called “Buffet”) contains multiple peptides and hyaluronic acid but does NOT include GHK-Cu.
This formula focuses on:
- Hydration
- Fine line reduction
- Skin texture improvement
It includes peptide complexes but no copper peptides.
2. Multi-Peptide + Copper Peptides 1% Serum
The second version of the product does contain GHK-Cu.
This formula includes:
- Copper Tripeptide-1 (GHK-Cu)
- Multiple peptide technologies
- Amino acids
- Hyaluronic acid
According to the product formulation, the serum contains 1% copper peptides, including GHK-Cu, along with other peptide technologies such as Matrixyl and ARGIRELOX.
This copper peptide version was originally known as “Buffet + Copper Peptides 1%.”
Key Ingredients in The Ordinary Multi-Peptide + Copper Peptides Serum
The copper peptide version of the serum contains several peptide technologies designed to target multiple skin concerns.
Copper Tripeptide-1 (GHK-Cu)
This is the key ingredient responsible for the serum’s copper peptide activity.
GHK-Cu may help support:
- skin regeneration
- collagen production
- antioxidant protection
- improved elasticity
It also gives the serum its light blue color, which is typical of copper peptide products.
Matrixyl Peptide Complex
Matrixyl peptides are designed to help support the skin’s natural collagen production.
These peptides may help reduce the appearance of wrinkles and improve skin firmness.
ARGIRELOX Peptide
ARGIRELOX is a peptide complex often used in anti-aging skincare products.
It is designed to help reduce the appearance of expression lines by targeting skin micro-movements that contribute to wrinkles.
SYN-AKE Peptide
SYN-AKE is another peptide included in some multi-peptide formulas. It is designed to help smooth the skin and reduce the appearance of fine lines.
Hyaluronic Acid
Hyaluronic acid is included to help maintain skin hydration.
This ingredient can hold large amounts of water, which helps keep the skin looking plump and smooth.
Amino Acids and Bio-Derivatives
The formula also includes amino acids and skin-supporting compounds that help improve the skin barrier and overall hydration levels.
Why Copper Peptides Are Important in Skincare
Copper peptides have become one of the most researched peptide ingredients in modern skincare.
GHK-Cu plays a role in several biological processes related to skin health, including tissue repair and collagen synthesis. These functions are important for maintaining healthy skin structure and reducing visible aging signs.
Some potential benefits associated with copper peptides include:
- improved skin firmness
- reduced appearance of wrinkles
- better skin elasticity
- support for skin healing
- antioxidant protection
Because natural levels of copper peptides decrease with age, topical skincare products often include them to help support skin health.
What Makes the Copper Peptide Version Different?
The main difference between the two peptide serums from The Ordinary is the addition of GHK-Cu.
Standard Multi-Peptide Serum
Focuses mainly on:
- hydration
- peptide support
- texture improvement
Copper Peptide Serum
Focuses on:
- advanced anti-aging support
- skin repair processes
- collagen maintenance
- skin resilience
The copper peptide formula is generally considered a more advanced peptide treatment.
Who Should Use a Copper Peptide Serum?
Copper peptide skincare products are often used by people who want to target visible signs of aging.
They may be suitable for individuals looking to address:
- fine lines and wrinkles
- loss of skin firmness
- dull skin texture
- early aging signs
Many people start incorporating peptide products into their skincare routines in their late twenties or early thirties as part of long-term skin maintenance.
How to Use The Ordinary Copper Peptide Serum
The serum is typically applied during the treatment step of a skincare routine.
Basic routine order:
- Cleanser
- Toner (optional)
- Multi-Peptide + Copper Peptides Serum
- Moisturizer
- Sunscreen (morning routine)
The product can be used once or twice daily, depending on individual skincare routines.
Some skincare guidelines recommend avoiding combining copper peptides with certain strong active ingredients like direct acids or pure vitamin C in the same routine.
Final Thoughts
Yes, GHK-Cu is present in one version of The Ordinary peptide serum—the Multi-Peptide + Copper Peptides 1% Serum. This formula contains Copper Tripeptide-1 (GHK-Cu) along with several other peptide technologies designed to support skin health, hydration, and the appearance of firmness.
However, the standard Multi-Peptide + HA Serum does not include copper peptides, so it is important to distinguish between the two versions when discussing ingredients.
Copper peptides like GHK-Cu are widely used in skincare due to their potential role in collagen support, skin repair, and improving visible signs of aging. When combined with other peptides, amino acids, and hydrating ingredients, they form a comprehensive skincare formula designed to promote healthier-looking skin over time.
