About Essential Six
The cornerstone of the RATIONALE range is the Essential Six—a system built around the six pillars of skin health and luminosity, and acknowledged worldwide as the definitive skincare routine for the prevention and treatment of skin ageing.
Tailored to every individual’s skin, an Essential Six prescription acts as the skin’s daily nutrition, providing all the Immune Boosters, Antioxidants, Environmental Protection, Barrier Fortification, pH Recalibration and DNA Repair needed for skin to glow with radiant health.
By day, the Essential Six ritual offers the world’s most comprehensive defence against 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. DNA repair processes are reactivated to support overnight repair and cellular regeneration for a visibly more luminous complexion by morning.
