Peptide Booster

Paula's Choice

Paula's Choice Peptide Booster takes a 'stackable' approach — it's sold as an additive you mix into your existing serum or moisturizer rather than a standalone treatment. The formula layers Matrixyl 3000 (palmitoyl tripeptide-1 + tetrapeptide-7), palmitoyl tripeptide-38 (Matrixyl synthe'6), and acetyl hexapeptide-8 (Argireline), giving three distinct mechanism pathways in one bottle. The booster format makes it practical for existing routines — no need to restructure what's working. Paula's Choice tests each formulation for photo and ingredient stability, which matters more for peptides than most actives.
