Longevity Skincare

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 position: one considered formula, used consistently, supporting the look of well-conditioned skin over months and years.

Why Copper Peptide

One peptide. Forty years of research.

Copper tripeptide-1 — GHK-Cu — occurs naturally in the body. It has been part of high-performance skincare for over four decades, studied across hundreds of peer-reviewed papers for its role in the skin's own maintenance signals.1

We didn't invent a proprietary molecule or wrap it in a pharmacy name. We built a focused formula around a well-understood active, at a concentration range consistent with the published literature, and packaged it to stay stable from the first press to the last.

THE RITUAL

  • 01 - CLEANSE

    Start with clean, slightly damp skin. The Renewal layers best on a hydrated surface.

  • 02 - APPLY

    Dispense 1–2 pumps into palms. Press gently into face and neck. Use day and night.

  • 03 - LAYER

    Allow 60 seconds to absorb. Follow with moisturizer or facial oil.

Why CODA Skin

Less, done better.

CODA Skin began with a refusal — to add another ten-step routine to a category already overflowing with them. We wanted one product we could stand behind completely: a copper peptide serum formulated with restraint, made in the USA, and honest about what it is.

No proprietary mystery. No transformation promises. A single, well-made formula and the patience to let it work. That is the whole brand, and we are proud that it fits on one shelf.
