Copper Theory
2% GHK-Cu + Tremella Firming & Hydrating Serum · 30 ml / 1 fl oz
Copper Theory is a firming-and-hydration serum built around a meaningful 2% dose of GHK-Cu copper peptide, with Tremella snow mushroom and sodium hyaluronate for lasting moisture. It's made to leave skin looking firmer, smoother, and better hydrated — and the faint blue you'll notice is the authentic copper peptide itself, never an added colorant.
The ritual
Start with clean, slightly damp skin, morning and evening.
Press gently into the face and neck. A little goes a long way.
Let it absorb fully before your moisturizer. Use daily for best results.
The science behind every drop
Each active earns its place. We read the research as supportive of mechanism — not as proof of any outcome.
A naturally occurring copper tripeptide — one of the most-studied peptides in skin science. In cosmetic research it's associated with the look of firmness, smoother texture, and a stronger-feeling moisture barrier. We use a meaningful 2% dose.
The snow mushroom, prized in traditional skincare for centuries. Its polysaccharides hold up to 500× their weight in water and sit lighter than hyaluronic acid — deep, weightless hydration that keeps the barrier comfortable.
Low-molecular-weight sodium hyaluronate that binds moisture at the surface for immediate, visible plumping — the fast-acting partner to Tremella's longer, deeper hydration.
Chosen with intention, down to the glass
Bottled in amber glass that shields light-sensitive copper peptides, with a bamboo dropper for precise dosing. Small-batch and batch-coded, so every bottle is traceable. The faint blue you'll notice is the copper peptide itself — authentic, never an added colorant.
What early testers say
Questions, answered
Why is the serum faintly blue? +
That tint is the copper peptide itself — a sign of the authentic active, not an added dye or colorant.
Will it work with my routine? +
Yes. Apply after cleansing and before moisturizer. Introduce one new active at a time and patch test if your skin is sensitive.
How soon will I see a difference? +
Skin renews in cycles, so consistency matters more than speed. Use daily and give the barrier a full cycle.
Pregnant or breastfeeding? +
We recommend checking with your doctor before introducing any new product.
