The ritual

How to use

Smooth a few drops over clean skin, morning and evening, before moisturizer. By day, it helps defend against the look of daily environmental stress; by night, it works quietly while you sleep. Gentle enough for the delicate eye area — just avoid direct contact with the eyes.
