What matches

Same two expression-line peptides as P-TIOX, acetyl hexapeptide-8 and the SYN-AKE dipeptide, plus pentapeptide-18 and Matrixyl collagen peptides in a water-based serum.

What the dupe does worse

It skips P-TIOX's 5% niacinamide and 5% PHA, so there is no exfoliating or tone-evening step, and The Ordinary doesn't publish its peptide percentages.
