Copper Theory
2% GHK-Cu + Tremella Firming & Hydrating Serum · 30 ml / 1 fl oz
2% of a 30 ml bottle is 600 mg of GHK-Cu. Most serums print a percentage — we print the milligrams, and batch-code every bottle.
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 blue you'll notice is the copper peptide itself, never an added colorant.
Who it's for
Anyone who wants skin that looks firmer and feels deeply hydrated, and is comfortable adding a copper peptide to their routine. Gentle enough for daily use; patch test first if your skin is reactive.
Full ingredients

How to use it
Apply 1–2 pumps to clean, slightly damp skin, morning and evening. Let it absorb, then moisturize, and use sunscreen in the morning.
It layers well with Vital Theory. If you use strong acids or vitamin C, use them at a different time of day.
When to judge it
Skin feels hydrated from the first use. The look of firmness and smoother texture builds with daily use, so give it 4–8 weeks before you decide.

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 bottle
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.
Sodium hyaluronate binds moisture at the surface for an immediate, plumped look — the fast-acting partner to Tremella's longer-lasting hydration.
Chosen with intention, down to the pump
Every bottle is an airless pump, which keeps air out of the formula and dispenses a measured amount. We make small batches every week and batch-code each one, so every bottle is traceable. The blue you'll notice is the copper peptide itself, never an added colorant.

Questions, answered
Why is it blue? Will it tint my skin? +
The blue is the copper peptide itself, not a dye. One or two pumps spread thin and absorb without tinting your skin.
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 feels hydrated from the first use. The look of firmness and smoother texture builds with daily use, so give it 4–8 weeks.
