Skin Identical Formulations | Rationale

Skin synchronicity.

RATIONALE has pioneered isotropy in dermatologic pharmacology. Every formulation we create is what we call Isotropic or "skin identical": meaning that every molecule delivers perfect synchronicity between active ingredient, formulation and your skin. All of this contributes to skin vitality and luminosity and an unprecedented level of efficacy and elegance. 

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

Everything we do begins by studying the way the skin naturally does what it is we are seeking to replicate, protect or repair... These insights then become the very essence of every product we make.

Richard Parker, Head of Research + Development

RATIONALE works in harmony to prompt the skin’s own defence and repair mechanisms, boosting immunity, calming inflammation, and improving hydration. Skin reflects a dewy radiance and appears to glow from within.
