GHK-Cu Copper Peptide Powder — Cosmetic Grade, Made for DIY Serums

GHK-Cu (Copper Tripeptide-1) is one of the most researched cosmetic peptides, valued by DIY skincare formulators for its role in skin barrier support and the appearance of firmness. Our powder is 99.7% pure, cosmetic grade, and ships from Australia for fast local delivery.

How to use: GHK-Cu is water-soluble and dissolves easily into water-based formulations. A common approach is to mix it into a hyaluronic acid base to create a high-strength peptide serum at home. As a guide, 2g makes up to 200ml of serum at 1% concentration, or 100ml at 2%. Start by dissolving the powder fully in a small amount of distilled water before adding to your base.

How to store GHK-Cu: Keep in a cool, dry place away from direct sunlight. Reseal tightly after each use, as the powder is sensitive to moisture. For long-term storage, keep the sealed bulk refrigerated with the included desiccant.

Why buy from Plainface: We're an Australian brand focused on minimalist, science-backed cosmetic ingredients. Every batch ships with purity documentation. For external/topical cosmetic use only — not for injection or internal use.

Frequently asked questions:

What concentration should I use? Most DIY formulators use 1–3% in water-based formulations.
Can I mix it with hyaluronic acid? Yes — it's a popular combination for a hydrating peptide serum.
Can I mix it with vitamin C or niacinamide? No — copper peptides shouldn't be combined with those; use them in separate products.
Do you ship within Australia? Yes, we ship from Australia with fast local delivery.
