The Science of RATIONALE

Human skin is our guiding light; our research library.

In its natural splendour, human skin is radiant, vibrant and translucent. Yet realising its ongoing perfection throughout life is an emergent endeavour.

RATIONALE Research recognises that now, more than ever, our skin is experiencing more of the planet and its diverse environments, traversing climates, time zones— and the decades of life.

Understanding how human skin responds to these experiences is what distinguishes RATIONALE and our revolutionary Research discipline. Decades of enquiry into the science of epigenetics— the ways in which lifestyle and environment influence the expression of our genes— has granted us a profound understanding of what skin needs to glow with radiant vitality as it carries us through life.

As always in nature, the answers reside within. But sometimes our skin needs external support.

For this, we look to the wisdom of nature, exhaustively studying a selection of Australian Botanicals to understand, extract and maximise the natural wisdom which has allowed these native species to not only survive a range of extreme environmental conditions— but to do so with striking natural beauty and brilliance.

This knowledge is distilled and imparted to skin in the form of RATIONALE formulations and facial treatments— a suite of luxurious experiences to enlighten, transform, and deliver Luminous Skin for Life.

Skin Identical Formulations

RATIONALE perpetually evolves in response to our profound understanding of human skin.
Our research, innovation and formulation science is informed by this knowledge of skin in its optimal state of health and radiance, honouring what skin needs throughout life to express vitality and luminosity.

RATIONALE has pioneered Skin Identical formulations, delivering perfect synchronicity between active ingredient, formulation and your skin. An unprecedented level of efficacy and elegance is reflected in a dewy radiance that glows from within.

Personalisation in Skincare

At RATIONALE, our focus is on the personalisation of skincare, and tailoring each Client’s individual pathway to Luminous Skin for Life. That’s why we encourage every Client to begin with a Consultation, so that our expert Skin Therapists can look at a person’s unique needs and develop a tailored, targeted plan just for them.

This can involve introducing different formulations at different times according to how their skin is presenting and progressing, alongside specific treatment modalities to help realise their skin goals.

We also offer The Platinum Experience, a sophisticated, two-phase Consultation experience which includes a non-invasive DNA test, allowing us to tailor an epigenetic skincare ritual based on their skin’s genetic strengths and weaknesses.
