Multi-Peptide + HA Serum

Formerly known as "Buffet", this is The Ordinary's kitchen-sink anti-aging serum: Matrixyl, Argirelox, and copper-free peptide complexes in a slightly tacky hyaluronic base. Devotees credit it with plumper, bouncier skin over months; skeptics call peptides expensive optimism. Still the brand's best-selling grown-up product.
