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 signalling proteins—which is why maintaining a healthy acidic balance is essential.

To optimise the skin’s immune defence 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.

Frequently Asked Questions

What is the benefit of masking?
Plus
Minus

Masking provides a potent, targeted infusion of active ingredients, enhancing your home care and treatment ritual when used weekly in addition to your Essential Six.

Can #1 The Mask, #2 The Mask and #5 The Mask be used during pregnancy?
Plus
Minus

Yes, RATIONALE can continue to be used during pregnancy.

Some RATIONALE Formulations contain a propriety Complex of Vitamin A derivatives. Oral and topical prescription strength vitamin A medication should be avoided during pregnancy. Whilst there is not data to suggest that applying over-the-counter retinol (non-prescription) can be harmful in pregnancy, we recommended speaking to your doctor before beginning or continuing the use of any vitamin a Formulations during this time.

If you have any concerns or further questions about using active ingredients in skincare during pregnancy, we recommend consulting your Medical Practitioner.

How many times a week can these masks be applied?
Plus
Minus

We recommend a weekly masking application. If you're targeting all three zones, you can utilise each one once a week on the corresponding area. To understand how you can incorporate masking into your RATIONALE Ritual, consult with your RATIONALE Skin Therapist or Medical Agency.
