Copper Peptide
Copper Peptide is a skincare favourite that combines the mineral copper with small protein fragments known as peptides. Often found in anti-ageing serums and creams, it is prized for its ability to support a firmer, smoother-looking complexion. UK shoppers will recognise it in many “next-generation” peptide moisturisers and eye treatments.
How it works in skincare
In cosmetics, copper peptide works by delivering copper ions into the upper layers of the skin where they help stimulate the natural production of collagen and elastin. The peptide carrier improves stability and skin penetration, allowing the ingredient to support the skin’s extracellular matrix and encourage a more youthful appearance. It is valued in formulations for its ability to visibly improve skin texture and tone without irritation for most users.

Where it comes from
Copper peptides are formed by binding the essential mineral copper with naturally occurring amino acid chains (peptides). While copper itself is a trace mineral found in foods and the earth, the specific GHK-Cu form used in cosmetics is produced in a laboratory for stability and purity.
