COSRX unveils 5 PDRN Vital Care Collection on Amazon

COSRX's first major post-Amorepacific-acquisition system launch dropped on Amazon November 10, 2025: a five-source PDRN serum anchoring a broader Vital Care collection alongside an upgraded Vitamin C 23 serum. Source-count differentiation (five distinct PDRNs in one formulation) is the most complex PDRN positioning on the US shelf, and the Amazon-first channel choice reinforces COSRX as Amorepacific's mass-tier US play.
