Founded in 1992 by cosmetic chemist Richard Parker, RATIONALE is an Australian luxury skincare brand built on a deep, scientific understanding of skin, particularly the effects of sun and environmental factors. Parker’s research into photobiology and epigenetics led to the brand’s core philosophy of achieving “Luminous Skin for Life” through formulations that work in harmony with the skin’s natural processes. The brand is renowned for its signature “Essential Six” collections, a prescribed daily ritual of three steps for morning protection and three for evening repair, designed to restore the skin's vitality and radiance.
