Who is it for?
How It Works
Rebuilds Collagen
GHK-Cu directly activates the fibroblast cells responsible for producing structural collagen. Not indirectly. Not as a side effect. This is its primary mechanism, documented in peer-reviewed research since the 1970s.
Reduces Inflammation
Chronic low-grade inflammation is the primary driver of accelerated skin ageing after 45. GHK-Cu inhibits the pro-inflammatory cytokines behind it, calming the environment your skin repairs in, not just the surface.
Works While
You Sleep
Collagen synthesis peaks during sleep. GHK-Cu signals that process from the moment it absorbs. By morning, 6 to 8 hours of active repair has already happened.
Key Ingredients
What it is
A tripeptide made from three amino acids, glycine, histidine and lysine, bound to copper ions. It occurs naturally in the body, with visible skin-supporting levels declining as skin matures.
What it does
Supports a firmer-looking, smoother-looking complexion by helping skin feel renewed and resilient. It is included for mature skin that looks tired, uneven or less bouncy than it used to.
The evidence
Copper peptides have been studied for decades in skin research. In skincare, GHK-Cu is valued because it fits a mature, science-led routine without the harsh peeling feel often associated with stronger actives.
What it is
CoQ10, also known as ubiquinone, is a naturally occurring antioxidant found in the body. In skincare, it is used to support skin exposed to daily environmental stress.
What it does
Helps skin look brighter, fresher and more energised. It pairs well with peptides because it supports the look of healthier, more rested skin.
The evidence
CoQ10 is widely used in antioxidant skincare formulas. It is especially relevant for mature skin routines where dullness, tired tone and environmental stress are key concerns.
What it is
Niacinamide is a form of vitamin B3, one of the most trusted cosmetic ingredients for supporting a smoother, more even-looking complexion.
What it does
Supports the skin barrier, improves the look of uneven tone and helps the complexion appear calmer and more refined over time.
The evidence
Niacinamide has become a staple in modern skincare because it is effective, well tolerated and easy to combine with other ingredients in a daily routine.

What Early Users Often Notice
“Skin feels calmer, smoother, and more comfortable”
Many women switching from stronger actives look for something that supports visible firmness without the usual redness, dryness, or adjustment period. With consistent use, the first thing many notice is a softer, more settled skin feel.
