About
An antioxidant-rich recombinant peptide derived from mussel tissue, with added methionine for enhanced stability.
This recombinant mussel-derived peptide includes an N-terminal methionine for improved stability, produced in E. coli via gene-synthesized fusion. Mussel-derived peptides are known for their high content of DOPA residues and antioxidant properties. The EU cosmetics framework treats this as a standard recombinant peptide without specific restrictions, though the mussel origin means potential marine allergenicity must be considered.
