Good skincare invites curiosity. What is in the bottle? What does the research tell us? How does it fit into a real day?
We begin with copper peptides, clear information, and a place in the routine you already have.

03 — Behind the blue
Three amino acids. One copper complex.A small peptide.
A closer look.
GHK brings together glycine, histidine and lysine. With copper, it forms the complex known as GHK-Cu — an ingredient that has drawn researchers’ attention for decades.
An ingredient’s research history is a starting point for learning, not proof of a finished serum’s performance.

07 — The people behind the ritual
A considered point
of view.
Alongside Alana, we are building Lumiere Routine around a simple idea: care in the details, clarity in the conversation, and room to keep learning.
A small collection. An open curiosity. A daily ritual that belongs to you.
Our story ↗Where does the serum fit in my routine?+
Use it as directed on clean skin, before moisturizer. Our morning and night guides show two possible ways to organize a routine; they are not an instruction to apply the serum twice daily.
Where can I find the complete ingredients?+
The full ingredient list is published on the product page. The formula includes royal jelly and is not vegan. Contact info@lumiereroutine.com before ordering if you need help checking a specific ingredient.
How should I store it?+
The label says to keep the serum in a cool, dry place. Refrigeration is recommended. Keep the bottle closed and the dropper clean.
How long does shipping take?+
Orders are typically processed in 2–5 business days, followed by approximately 3–10 business days in transit. Your destination and carrier can affect timing. Read the shipping policy.
