Why copper peptides
The blue is not a dye.
It is the ingredient.
Copper Tripeptide-1 gives the serum its soft blue tint — a visible marker that the peptide is actually in the bottle at a meaningful concentration. If a “copper” serum isn’t blue, ask what’s in it.
01
Firmer-looking skin
GHK-Cu is among the most-studied cosmetic peptides for supporting the look of firmness and elasticity.
02
Even, hydrated tone
Paired with niacinamide and sodium hyaluronate for even-looking tone and lasting hydration.
03
A routine you keep
One clear step in the morning, one in the evening. No twelve-step shelf, no guesswork.

Before you buy
Honest answers, up front.
Why is the serum blue?+
GHK-Cu is naturally blue — that soft tint is the copper peptide itself, not a dye. If a 'copper' serum isn't blue, ask what's in it.
Which serum should I start with?+
Both are built around 1% GHK-Cu, so you only need one. The copper serum is the everyday choice; the exosome serum is the advanced option with 1 billion exosomes. Keep retinol and vitamin C to alternate times of day.
How long does a bottle last?+
Each 30 mL bottle lasts around 30 to 45 days with regular daily use.
What about shipping and returns?+
Orders process in 2–5 business days. Opened skincare is generally non-returnable; damaged, defective, or incorrect items are covered within 7 days of delivery.
