The Story
Purified, polished perfection.

A sophisticated gel formulation, #5 The Mask is designed to restore the skin’s inherent clarity. This weekly treatment harnesses a powerful yet gentle complex of organic acids to recalibrate skin’s pH and refine texture. As hydration is delivered, a picture of unbridled radiance is revealed.

The Promise
• Masterfully purifies the skin
• Recalibrates skin pH to a youthful, acidic level
• Instantly reveals a brighter, more radiant complexion
• Elicits a supremely soft, supple texture
• Skin is left nourished, hydrated, and radiant

The Ritual
Apply a generous layer to clean, dry skin. Allow the mask to infuse for 20 minutes, then rinse thoroughly with tepid water.

Gently pat dry and follow with your recommended RATIONALE Essential Six formulations. Perform once weekly for remarkable skin luminosity.

The Research
Clear, radiant skin is intrinsically connected to the health of the skin’s microbiome. This complex ecosystem is influenced by various factors—including its acidic pH, vital enzyme function, moisture reserves, and signaling proteins—which is why maintaining a healthy acidic balance is essential.

To optimize the skin’s immune defense systems, desirable bacterial colonies must be evenly distributed and active. Changes to the epidermal ecosystem caused by changes to skin pH or compromised barrier function, may result in an accumulation of pathogenic Colony Forming Units (CFUs) inside pores. This may lead to clogged pores, breakouts, increased sebaceous output and a rough, dry, sensitive texture.

RATIONALE Research has identified and combined two potent yet calming actives – Salicylic Acid and Piroctone Olamine that help to restore optimal CFUs, controlling congestion and breakouts.

In addition, an imbalanced pH impairs the function of enzymes, lipid synthesis and cellular turnover, while depleting our skin of essential structural proteins. These effects are further accelerated following exposure to pollution and solar damage. All of these vital cellular processes are restored when skin pH is recalibrated back to youthful, acidic levels, restoring a radiant, purified complexion.
