The Sound Effect

Finding a Perfect Musical Accompaniment for the RATIONALE Treatment Experience

What was it that made your last facial so memorable?

Was it the afterglow? The sharper features and brighter eyes?

That special sort of magic that comes from a combination of rhythmic massage, a heated bed, the warming glow of an LED lamp, and the friendly reassurance from your therapist: “don’t worry, it’s a good thing if you fall asleep”?

These are just some of the things that spring to mind when we think about those magical, counting-down-the-days moments in our calendar.

In the serene space of the treatment room, every sensory aspect has been carefully considered and fine-tuned to gently comfort the senses: the darkened room to relax the eyes, the opening inhalations using aromatic formulations, the power of touch—expertly dispensed from the hands of our therapists…

But there’s a new sensory element to our treatment offering which we’ve spent many months researching, contemplating, trialing and refining: sound.

A passion project of Founder Richard Parker for many years, it has long been Parker’s desire to curate a playlist that matched the experiential nature of our treatments. After many hours of research—a real labour of love for classically trained Parker—he discovered the work of British-German composer, Max Richter.

The Research

A vibrant, radiant complexion is intimately connected to the pH of the skin’s outermost layer, the Stratum Corneum.

Sensitivity, barrier breakdown, pigmentation and premature ageing are all consequences of environmental damage. These occur as a result of excessive solar exposure, causing the skin’s pH to shift from a healthy acidic state to alkaline, triggering the upregulation of enzymes that break down connective tissue and erode protective barrier structures.

Signalling peptides in human skin direct all metabolic processes, including desquamation (cell turnover), cellular differentiation (cellular function), and hydration. Short-chain protein sequences and ceramides are critical in these intercellular communication processes.
