Rationale Comes to the UK

Australian skincare brand Rationale has arrived in the UK through an exclusive partnership with Harrods.

The brand, which was founded over 30 years ago, was created by Richard Parker, a cosmetic chemist who dedicated his career to understanding the impact solar exposure has on skin health. His findings inspired the brand’s signature philosophy — healthy, glowing skin can be achieved when skin’s natural resilience is supported by daily protection and repair.

Today, the research-led skincare brand is praised for its meticulous formulations, beautiful textures, and transformative results. It even has its own in-house laboratory and manufacturing facility in Melbourne, raising the bar for evidence-based skincare.

For Rationale, optimal skin health is achieved through a routine that protects skin by day and repairs it by night. Each of the brand’s formulas is engineered to treat skin concerns associated with environmental and solar damage: barrier health, pigmentation, inflammation, dryness, refinement, and regeneration.

The brand launches into Harrods with bestsellers from The Essential Six — a structured skin system designed to improve skin tone, texture, clarity, and luminosity.

Intended for daytime use, The Strengthening Serum reinforces the skin barrier and enhances hydration, while The Brightening Light Crème evens and brightens the complexion.

The Nourishing Eye Crème hydrates, firms, and brightens the eye area; The Brilliance Tinted Serum SPF50+ combines advanced sun protection with antioxidant support in one sheer, luminous tint; and The Nourishing Cleanser removes impurities while preserving essential moisture.

Designed for evening application, The Refining Serum exfoliates to refine skin texture, and The Rejuvenating Night Crème supports renewed skin turnover, boosting radiance while you sleep.

Launching alongside these skincare essentials is an edit of Beautiful Balms — Rationale’s makeup offering. Inspired by Australia’s intense daylight environment, the balms are formulated with broad-spectrum SPF protection, advanced antioxidants, skin-identical lipids, and hydrating complexes. Available in a highlighter, bronzer, blush, and lip format, they each shield against UVA and UVB exposure, correct sun-induced pigmentation, preserve the skin’s barrier, and deeply nourish, all while delivering a wash of colour that enhances the skin’s natural glow.

Rationale is now available at Harrods and online at harrods.com, with prices ranging from £55 to £152 ($69 to $179). US customers can shop the brand at rationale.com.
