Since 1992, cosmetic chemist Richard Parker has dedicated his career to creating skincare formulations that are considered the platinum standard in protecting and restoring skin’s natural luminosity and beauty. His pioneering research into the relationships between skin genetics and epigenetic environmental influences led to Parker’s development of the RATIONALE Essential Six Collections — a daily skincare ritual.
In the early 1990s, Richard Parker was working as a formulation chemist alongside a team of Melbourne dermatologists investigating the effects of laser treatments on sun-damaged skin. Their findings were striking: 80 per cent of facial ageing is caused by the sun. For Parker, that statistic revealed both a challenge and an opportunity. “Our skin health and beauty are very much under our control,” he says.
Parker’s ongoing research into skin genetics led to the discovery of what he calls the Six Pillars of Skin Health — biologic systems that protect the skin by day and repair it by night. The three daytime pillars focus on Immune Protection, Antioxidant Protection and Environmental Protection; at night, Barrier Repair, pH Repair and DNA Repair take over to restore balance and vitality.
These discoveries became the foundation for RATIONALE, a brand that blends vitamins, minerals, lipids and proteins that mirror the skin’s own composition. “We are not a skincare company that does research,” Parker explains. “We are a research company that creates game-changing skincare.”
At the heart of this philosophy lies the RATIONALE Essential Six — a streamlined daily ritual that supports the six facets of skin vitality. Parker describes the premise simply: “three products in the morning for solar protection, and three at night for solar repair.” The result? Skin that is “healthy, glowing, dewy and hydrated.” As Parker puts it, “we can’t look young forever, but we can be beautiful at any age.”
Guests at COMO The Treasury can experience Parker’s research firsthand through three new facial treatments developed in partnership with RATIONALE. Each treatment harnesses advanced formulations and customisable elements to counteract the effects of solar ageing while enhancing luminosity and skin health.
Every element is tailored, from the ingredients used to the time of day a treatment is performed. Morning appointments include SPF application to protect freshly treated skin, while evening sessions focus on deep repair and rejuvenation. Guests seeking to brighten or even their complexion may receive Vitamin C, while those looking to strengthen the skin’s defences could benefit from antioxidant-rich Vitamin D or soothing LED light therapy to reduce inflammation.
Parker describes RATIONALE’s collaboration with COMO The Treasury as “a beautiful alignment,” melding high-performance skincare with nurturing ritual. Each treatment offers something a little different. The Rejuvenating Renewal Treatment is a universal boost for lacklustre skin, designed to nourish, brighten and restore balance — especially after a little too much time in the sun. The Orbital Booster, meanwhile, is a targeted enhancement to refresh and revitalise the eye area, ideal after travelling. For the ultimate indulgence, Parker recommends the two-hour Renewal Clarity treatment, an immersive experience that delivers both deep relaxation and radiant results.
Whichever option guests choose, Parker is clear: every RATIONALE treatment delivers more than surface-level results — it’s a journey into the science of lasting beauty, where protection, prevention and repair work in harmony.
