Skincare that is with you for the long run.

Most skincare chases a fast result, then asks you to chase the next one. We take the opposite view: the skin you want later is built by what you do, consistently, now.

Inside the bottle

The Renewal

Intention over excess. The Renewal is one proven active — copper tripeptide-1 — lightweight, fragrance-free, and made to work on its own rather than pile onto a routine. Not more steps. The right one.

Why Copper Peptides

One peptide. Forty years of research.

Copper tripeptide-1 — GHK-Cu — is a small peptide bound to a copper ion. The body makes it naturally, and levels decline with age. It's one of the most-studied peptides in skin science, researched for over four decades.1

Studied for its role in

  • the look of firmer, more resilient skin
  • a smoother, more refined surface
  • a hydrated, healthy-looking finish

Proven on Paper

Tested, not just promised.

A Certificate of Analysis is an independent lab report that confirms what's actually in a product — that the active is present at the level claimed, and that it's free of contaminants. Few brands ever show you one. We third-party test every batch of The Renewal, so the copper tripeptide in your bottle is verified, not assumed.

Identity

Confirms the active is exactly what we say it is — copper tripeptide-1, not a substitute.

Potency

Verifies the peptide is present at the intended concentration, batch after batch.

Purity

Screens for contaminants and heavy metals, so what reaches your skin is clean.
