GHK-Cu Night Cream · 50 Years of Skin Science
A copper-peptide night cream built on fifty years of published skin research — applied like a ritual, once a night, in the dark.
The Object
Heavy amber-black glass, cream label, machined copper cap that lands with weight. No tube — a tube is a pharmacy; this belongs on a bedside table.
Two fingertips, last step, lights low. Warmed in the palm for three seconds, pressed upward along the jaw. Thirty seconds, every night.
1973
Identified in human plasma and studied in skin since the 1980s. Naturally present in the body; less abundant with age. Fifty years of skin literature, stated plainly and once. We name the year, not the p-value.
AQUA · GLYCERIN · COPPER TRIPEPTIDE-1 · SQUALANE · PANTHENOL

From the ritual
"I started thinking of it as the last thing I do before sleep, not a skincare step. Eight weeks in and my skin just feels... denser. Less fragile in the morning."
"The ritual is the point. Two fingertips, thirty seconds. I didn't expect to actually stick with it — but the glass jar and the weight of the cap make it feel real."
"I'm not a skincare person. But the ingredient story — 1973, the same compound your body makes — that made sense to me. Results came after about six weeks."
Questions
Keep SUNA away from acids and vitamin C in your evening routine. Apply it last, after any actives have fully absorbed. The routine is short on purpose — a first peptide should be easy to keep.
Most people report noticing a change in how their skin feels after four to six weeks of consistent nightly use. The full ritual is designed around eight weeks — that's when the literature on GHK-Cu becomes most relevant.
GHK-Cu is naturally present in the human body. The formula is designed to be well-tolerated, but as with any new skincare product, we recommend a patch test first and introducing it gradually into your routine.
Light degrades peptides. A pump would require an opaque container and a exposure window. A dark glass jar with a copper cap keeps the formula stable, and the weight of the cap is part of the ritual — it lands, it closes, lights out.
Barely anything. Minimal, neutral scent — no added fragrance. The copper-peptide molecule has a faint metallic quality that dissipates as the cream absorbs. This is intentional: the ritual happens in the dark, with lights low.
Yes. One formula, 50ml, €70. We didn't want to give you six options that all do slightly different things. GHK-Cu is the ingredient. SUNA is the ritual. That's it.
