80% of facial ageing is caused by the sun.

As a research-driven Australian cosmeceutical company, Rationale leads the world in the prevention and treatment of sun damage.

In 20 years we've transformed the beauty landscape in Australia, delivering luminous skin for a lifetime through the creation of luxurious, high potency medical skincare formulations and facial treatments that deliver on their promises.

Skin is our inspiration. Our research library. Our guiding light.

Everything we do, every product we make, begins by studying the way the skin naturally does what it is we are seeking to replicate, protect or repair. How it looks, feels and behaves when it is in a state of optimum health and radiance. What it needs throughout life to constantly bring it back to this point of vitality and luminosity. These insights then become the very essence of every product we make.

The cornerstone of the Rationale range is The Essential Six; a proven medical skincare regime ensuring optimal levels of the essential vitamins, minerals and botanical actives that deliver visible, measurable skin health and radiance.

The Rationale Essential Six products work in synergy, delivering the correct combination of active ingredients at the correct concentration to be recognised and utilised by skin cells to restore vitality and protect from future damage. The system is simple – 3 steps in the morning and 3 at night. Complete skin protection and repair. Sensational skin in just six steps. For all skin types.
