GHK-Cu Copper Peptide
A naturally occurring tripeptide bound to copper. Studied for its ability to signal fibroblast activity, supporting collagen and elastin production. We use it at 0.05% — enough to act, never to irritate.
The science
We work with chemists in Stockholm and Porto to keep our ingredient list short and our concentrations honest. Below, the molecules that do the work.

02
Two molecular weights, layered. The lighter penetrates beneath the stratum corneum to hydrate at depth; the heavier holds moisture at the surface, smoothing the appearance of fine lines almost immediately.
03
A quiet botanical base that calms reactivity and reinforces the skin barrier. Centella asiatica has been used in East Asian skincare for centuries; we honour that lineage with a cold-extracted variant from Jeju.
