Tripeptide-32
Definition
A peptide patented by Estée Lauder that activates CLOCK gene and PER1 circadian rhythm signalling in skin cells, supporting the skin's natural 11pm–3am repair window. Genuinely proprietary IP — no other brand currently uses this exact tripeptide.
Why it matters for dupe shopping
Tripeptide-32 accounts for an estimated 15–20% of ANR's total efficacy; the remaining 80–85% is attributable to the Bifida ferment, which IS replicable. Understanding this distinction allows a rational choice: pay the ANR premium for the 15–20% Tripeptide-32 benefit, or build the Ferment Stack for the replicable 80% at $60.
