Copper Peptide Serum

1% GHK-Cu + Matrixyl 3000 + Argireline

A concentrated multi-peptide serum formulated with 1% GHK-Cu (Copper Tripeptide-1) alongside complementary signal peptides to support firmer, smoother-looking skin and improve the appearance of fine lines and age-related changes in skin texture.

What Makes This Formula Different?

Not all peptide serums contain the same peptides—or disclose their concentrations.

Dr. Brenner Copper Peptide Serum combines 1% GHK-Cu with multiple complementary peptides in a lightweight, fragrance-free serum.

This formula includes:

• 1% GHK-Cu (Copper Tripeptide-1) — a naturally occurring copper-binding peptide studied for its role in skin repair and extracellular-matrix remodeling
• Matrixyl 3000 — a peptide complex containing Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7
• Argireline (Acetyl Hexapeptide-8) — a cosmetic peptide commonly used in formulas targeting the appearance of expression lines
• Palmitoyl Pentapeptide-4 — a signal peptide used in anti-aging skincare formulations

No fragrance. No essential oils.

How Does This Serum Work?

GHK-Cu has been investigated for biological processes relevant to aging skin, including tissue remodeling, wound repair, antioxidant activity, and extracellular-matrix production.

The complementary peptides in the formula target additional pathways associated with the appearance of aging skin.

With consistent use, the formula is designed to help:

• Improve the appearance of fine lines
• Support firmer, smoother-looking skin
• Improve visible skin texture
• Support overall skin resilience and quality

Changes involving skin structure occur gradually, so consistent use is more important than expecting immediate results.

Who Is It For?

This serum is designed for concerns including:

• Fine lines and wrinkles
• Loss of firmness
• Uneven or rough skin texture
• Visible signs of skin aging
• Skin that would benefit from a peptide-focused routine

Suitable for a wide range of skin types. Those with particularly reactive skin should introduce any new active product gradually.

Why GHK-Cu?

GHK-Cu is a naturally occurring copper-binding peptide found in the human body.

Its biological activity has made it an area of scientific interest in research involving tissue repair, extracellular-matrix remodeling, and skin aging.

Dr. Brenner Copper Peptide Serum contains 1% GHK-Cu (Copper Tripeptide-1) and clearly identifies the concentration rather than simply listing “copper peptides” as a marketing claim.

How to Use

Apply 2–3 drops to clean, dry skin once daily.

Follow with moisturizer as needed.

Copper peptides can be incorporated into a routine alongside other skincare actives. If your routine contains multiple high-strength products or your skin is easily irritated, introducing them at different times can simplify your routine and help identify sources of irritation.

When Will I See Results?

Copper peptides should not be expected to produce dramatic changes overnight.

Changes in skin texture, firmness, and the appearance of fine lines generally develop gradually with consistent use over weeks to months.

Results vary depending on skin condition, routine, and consistency of use.

Frequently Asked Questions

What is GHK-Cu?

GHK-Cu is a copper-binding tripeptide also known in cosmetic ingredient labeling as Copper Tripeptide-1. It has been studied for biological activity relevant to tissue repair and skin aging.

Why is the serum blue?

The characteristic blue color comes from the copper-peptide complex itself.

Does this serum contain 1% GHK-Cu?

Yes. Dr. Brenner Copper Peptide Serum is formulated with 1% GHK-Cu (Copper Tripeptide-1).

Can I use copper peptides with Vitamin C?

Both can be incorporated into a skincare routine. A simple approach is to use Vitamin C in the morning and copper peptides in the evening, particularly if you prefer not to layer multiple active serums at once.

Can I use copper peptides with retinoids?

They can be incorporated into the same overall skincare routine. If your skin is sensitive or your retinoid causes irritation, using the products at different times or on alternate nights can make the routine easier to tolerate.
