My Skincare Rationale

the rationale story


Rationale Founder Richard Parker’s story started with his own disappointment at skincare that promised (but failed) to change his own problematic skin; a combination of sun damage and acne. So he embarked on a self-directed journey to discover “what works”.

Through a combination of formal studies and independent scientific research over many years, Richard discovered the truth about skincare, and the skincare industry. If this was going to work, it was going to take a radical approach that connected the worlds of beauty and medicine.



In 1991 Richard was approached by a group of Australian Dermatologists to develop a range of high-performance cosmeceutical products that prevented and treated the major cause of skin ageing; The Sun.

Many years of meticulous research and development followed, resulting in impressive outcomes, the hard-earned seal of approval from Dermatologists and a ripple effect throughout the greater medical fraternity. Rationale swiftly became the most sought after brand by leading Dermatologists and progressive Plastic Surgeons.
