Essential Six

Richard Parker’s Essential Six Philosophy

I know what your skin is looking for; the same active ingredients it contains naturally to keep everything bright and beautiful. Rationale Skin Care's Essential Six delivers the right combination of these actives at the correct concentration to be recognised and used by skin cells for maximum vitality and luminosity. You’ll need three products in the morning for complete protection and three at night for optimal repair. Sensational skin in just six steps. For all skin types.

Morning: threefold day protection

Daytime radiance starts with an immune booster to restore luminosity and target pigmentation. Follow with a potent antioxidant and anti-glycation combination to re-firm and refine. Finish with a super hydrating SPF15 day cream offering photoprotection throughout the entire Solar Constant (UV, InfraRed + Visible Light) starring skin nutrient Zinc, Melanin and light activated rejuvenators:

STEP 1. skin vitality + Resilience

Rationale IMMUNOLOGIST Niacinamide Serum conveys skin clarity and calmness. Vitamin B3 boosts the skin’s immune responses and targets pigmentation, while photoprotective and antioxidant botanicals reinforce solar defenses.

Rationale SUPER ANTIOXIDANT ACE Rejuvenating Serum rejuvenates, re-firms and reactivates luminosity with skin-identical Vitamins A, C + E. Lycopene, Ubiquinone and a proprietary blend of Australian photoprotective botanicals deliver powerful antioxidant and antiglycation protection, while Ceramides replenish the intercellular lipids responsible for skin hydration and radiance.

Finish with three potent forms of Vitamin A plus DNA Repair Enzymes to target cellular DNA damage, in a nourishing lipid-rich crème for optimal overnight rejuvenation and repair:


Rationale PROCERAMIDE EMULSION Preparatory Cleanser inundates the skin with a cascade of nourishing lipids, boosting hydration and firmness. Infused with powerful antioxidants, botanical purifiers and Ceramides, ProCeramide Emulsion replenishes the skin’s intercellular lipids as it gently cleanses away surface impurities and make-up.


Rationale CATALYST Skin Refining Serum reactivates vital youth enzymes through recalibration of the skin’s pH, enhancing radiance, firmness, hydration and clarity. By bringing skin pH back to youthful acidity, Pro-Vitality + Pro-Luminosity enzymes are activated. Skin looks and feels immediately resurfaced and perfected – smoother, softer and clearer. Instant luminosity.
