Safety score · 0–100

Moderate

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A fat-modified copper peptide that builds on the classic GHK-Cu structure. Designed to slip into the skin more easily and support a firmer, smoother look over time.

Function

ANTIOXIDANT

Skin benefits

  • Lipid-modified copper peptide designed to penetrate the skin barrier more readily than GHK-Cu alone
  • Supports the appearance of firmness and may help signal collagen and elastin synthesis
  • Palmitamide tail boosts compatibility with oil-phase and anhydrous formulations
  • Targeted anti-ageing actives often used at very low percentages

Known concerns

  • No PubChem record returned for CAS 2133832-31-0, so no public hazard data is available
  • Copper peptides can be unstable with strong acids, vitamin C, or high levels of antioxidants
  • Limited independent safety review for this lipidated copper tripeptide derivative
  • Potential for sensitisation in a small subset of users, as with other copper complexes
