About Essential Six
The cornerstone of the RATIONALE range is the Essential Six Collections—a system built around the six facets of skin health and luminosity, and acknowledged worldwide as the definitive skincare for skin protection and repair, restoring natural beauty and radiance.
Tailored to every individual’s skin, an Essential Six Ritual acts as the skin’s daily nutrition, providing all the Skin Resilience Boosters, Antioxidants, Environmental Protection, Barrier Fortification, pH Recalibration and Nightly Repair needed for skin to glow with radiant health.
By day, the Essential Six ritual offers vital support to skin’s innate resilience, antioxidant nourishment to boost skin vitality, and delivers comprehensive protection from the entire Solar Constant—made up of ultraviolet, visible light and infrared radiation—as well as against pollution and other environmental aggressors.
By night, the Essential Six evening routine works to repair and reverse daytime damage by replenishing the skin’s lipid barrier and recalibrating skin’s pH to a healthy, acidic level. Repair processes are supported for overnight rejuvenation and cellular regeneration for a visibly more luminous complexion by morning.
