To ensure consistency, upkeep is certainly necessary. Think polished metals, blooming plants and even healthy skin. For the latter, ageing is the main enemy, but prevention can delay the onset of maturity. Hence, trust Rationale’s epigenetics-based products to provide external support for the skin.
Founder and director of research Richard Parker started the company in 1992 and looked into the science of epigenetics. This study explores the ability to switch genes on and off. Research shows only around 25 percent of ageing is predetermined by your genes, and the rest is influenced by environmental and lifestyle factors. As a cosmetic chemist and medical dermatology, Parker identifies that even though all human skin is unique, it requires nutrition from antioxidants and sunscreen protection to defend against harsh external stressors.
Using this technology to formulate Rationale’s personalised skincare solutions and products, Parker’s goals in delivering radiant health amassed impressive credentials such as having 14 flagships in Australia, alongside a network of medical stockists in Australia and the UK, and its namesake online site.
Singapore is the brand’s pick for its first two international flagship outlets. This is no surprise as Rationale’s market research revealed the country’s target demographic is among the most highly educated in skincare in the world. Besides the products, both Raffles City and Tangs flagships also provide in-depth skin consultations and personalised facial treatments.

What defines Rationale is The Essential Six skincare collection offering. The six pillars—resilience, vitality, brilliance, integrity, clarity and renewal—each target various aspects of skin health.
Undecided on what nourishment your skin needs? For starters, the team at Rationale will guide customers on using the most suitable two to three products across specific pillars.
My Rationale journey began with a detailed in-person consultation at the 230-square-metre Raffles City flagship, which boasts four treatment rooms. During the comprehensive Rationale Signature Skin Consultation (SGD100 for one hour), my consultant explained the condition of my skin, past treatments done, and also discussed pressing skin concerns. This was followed by a double cleanse with a skin analysis under magnification light and capturing UV diagnostic images to reveal skin dynamics.
The analysis accurately pointed out my skin’s constant exposure to UV rays and irregular sunscreen application (found guilty!). An immediate save came after, with a Photogenic Resilience Facial (SGD230 for one hour) to reawaken radiance by restoring bright skin tone with a concoction of antioxidants, micro-circulatory massage and rejuvenating LED therapy.
Concluding this session was a run-through of at-home rituals and a tailored treatment plan from The Essential Six collection. As someone with normal-to-oily skin and who appreciates a straightforward regime, I was elated that Rationale offers products with mild textures and diverse moisturising hydrators to suit different climates and skin types. My prescription includes #3 The Day Crème SPF15 which moisturises the skin and sun protects at the same time, while the #1 Serum is tasked to plump up my skin; this suitable-for-morning wonder cultivates skin calmness, strengthens skin barrier function and improves clarity while you’re on the go.
Rationale is at Raffles City Shopping Centre #01-19 and Tangs at Tang Plaza Level 1. Products from The Essential Six start from SGD114 for a cleanser.
