The formula, made visible

The blue is not a dye.
It is the ingredient.

Copper Tripeptide-1 gives the GHK-Cu serum its soft blue tint. We pair it with niacinamide and sodium hyaluronate in an everyday formula designed to support hydrated-looking, smoother-looking skin — without turning a routine into a twelve-step project.

Featured · The morning step

1% GHK-Cu. Naturally blue. Zero filler.

Most routines add more. This one concentrates: a full 1% of the copper peptide GHK-Cu, supported by niacinamide and sodium hyaluronate, for skin that looks smoother, firmer, and more evenly lit. Nothing in the bottle is there for show — including the color.

1%GHK-Cu

The naturally blue copper peptide, dosed at a full one percent in both serums.

1BExosomes

One billion exosomes in every bottle of the evening renewal serum.

2Steps

One serum for morning, one for evening. The whole ritual, edited to what matters.

A clear role for each step

Treat by day. Renew by night.

The ritual is intentionally small: one serum for the morning, one for the evening, and a straightforward way to use both.

GHK-Cu Copper Peptide Serum

02 · Evening

Exosome Renewal Serum

Apply the evening formula to clean skin. It brings 1 billion exosomes and 1% GHK-Cu into the second half of the ritual, with a role that stays simple and distinct.

“A routine should end
at enough.”

The Lumiere Routine principle

Clear answers before checkout

The details should be easy to find.

Why is the serum blue?

The blue tint comes from Copper Tripeptide-1 (GHK-Cu), not added dye. It is a visible part of the formula, not a visual effect layered on top.

Where does each serum fit in a routine?

Use the GHK-Cu Copper Peptide Serum as the morning step, then reserve the Exosome Renewal Serum for the evening. Together, they make the AM/PM order clear from day one.

What should I expect from shipping and returns?

Orders are typically processed in 2 to 5 business days. Opened skincare is generally non-returnable; if an item arrives damaged, defective, or incorrect, contact support within 7 days of delivery.
