A peptide, gently introduced
GHK-Cu is a copper tripeptide first identified in human plasma — a tiny chain of three amino acids (glycine, histidine, lysine) bound to a single copper ion. Naturally present in the body, levels are at their highest when we are young, and decline meaningfully with age. Researchers have spent decades exploring it, and skincare has finally caught up — softly, without drama.
Why it matters for skin
On a healthy skin barrier, GHK-Cu is studied for its supportive role in firmness, soft texture, and the appearance of even tone. It is best thought of as a long-term ingredient: not an active that performs in a week, but one that quietly contributes over months of consistent use.
- Supports the appearance of firmer, healthier-looking skin.
- Pairs beautifully with hydrators and barrier-friendly creams.
- Gentle enough to layer in both morning and evening routines.
Why 3.33%
We landed on 3.33% intentionally. It is generous enough to feel like a considered investment — meaningfully above the trace amounts found in most "peptide" serums — while remaining elegantly lightweight on the skin. Higher does not always mean better; thoughtful does.
Niacinamide, the quiet companion
We paired GHK-Cu with niacinamide (vitamin B3), a long-loved ingredient for the look of softer pores, calmer-looking redness, and an evenly radiant finish. Together, they support a single goal: skin that simply looks like itself, on a very good day.
How to use it
Apply 3–4 drops to clean, dry skin, morning and evening. Press gently into the face and neck, then follow with moisturiser. In the morning, always finish with SPF. It layers comfortably under retinoids in the evening.
A note on patience
Skin keeps a slower calendar than we do.
Give any new routine eight to twelve weeks before deciding. Take a photograph at the beginning. Then go quietly about your life — and let consistency do the work that intensity cannot.
