This vs That · Skin School
Both calm the skin — but they play different roles. Guaiazulene is a targeted soother for reactive, flushed skin; cica (Centella) is a broad multitasker for everyday barrier comfort.
Quick answer — For fast, focused calming of reactive or hot-feeling skin, start with guaiazulene. For all-round everyday comfort, reach for cica. Many routines use both — and Klairs' Midnight Blue Calming Cream actually combines them.
