ION BLUE GHK-Cu 0.10% Copper Peptide Serum
One copper peptide. One disclosed concentration. Nothing to hide.
A GHK-Cu (copper tripeptide-1) facial serum at a real, disclosed 0.10% — no blends, no fillers, no diluted formulations. Fragrance-free and built around a single active that earns its place. Formulated to support the look of healthy, firmer-looking, smoother skin over time.
What it is
GHK-Cu is a signaling peptide that occurs naturally in the body and has been studied for its role in skin biology. In our serum, it's used to support the appearance of firmness, smoothness, and overall skin quality with consistent daily use. We keep the science and the product separate on purpose — you can read the underlying research on our Science and Scientific References pages and judge it for yourself.
Why 0.10%
GHK-Cu is studied to be active at very low concentrations, so a bigger number on a label isn't automatically better. We chose a considered, disclosed 0.10% — and we tell you exactly what it is. Here's the full reasoning →
What's in it — and what isn't
Centered on Copper Tripeptide-1 (GHK-Cu) at 0.10%. Fragrance-free. No proprietary blends, no fillers, no diluted formulations. Just the disclosed active and what's needed to deliver it well.

Built Around Peptide Science
Focused Ingredients. Science-Driven Design.
A Formula Centered on Skin Biology
Every ingredient in the ION BLUE GHK-Cu Serum was selected to support a simple objective: create a formulation centered around skin biology and the science of peptides. Rather than relying on dozens of trend-driven ingredients, our approach focuses on a carefully balanced formula built around Copper Tripeptide-1 (GHK-Cu), hydration support, and formulation stability.
Peptides function as biological messengers, helping cells communicate and respond to their environment. Among the most studied skincare peptides, GHK-Cu has been researched for its relationship to fibroblasts, extracellular matrix function, collagen signaling, and processes associated with maintaining healthy-looking skin.
Our philosophy is straightforward: fewer ingredients, transparent concentrations, and formulations designed with purpose. By focusing on peptide science rather than unnecessary complexity, ION BLUE delivers skincare built around what matters most — supporting the skin's natural biological processes.
Transparent By Design
Every Ingredient. Fully Explained.
Transparency is a core part of the ION BLUE philosophy. We believe people should know exactly what they are putting on their skin and why each ingredient is included. That's why we focus on clear formulation choices, straightforward explanations, and openly disclosed ingredient information.
Our goal is to remove unnecessary complexity and help people better understand the science behind their skincare. From Copper Tripeptide-1 (GHK-Cu) to supporting ingredients that contribute to hydration, stability, and product performance, every component serves a defined purpose within the formula.
We are committed to providing educational resources that explain skin biology, peptide science, and formulation decisions in a way that is accessible, evidence-based, and easy to understand. Because informed decisions start with transparent information.
