What it is and what it does

The Ritual

Allow mask to infuse for 20 minutes.
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
Playing a vital daily role in the prevention of environmental damage, allergy and disease, the skin’s own immune system is comprised of site-specific cells and tissues that contribute to radiance and resilience.
The skin’s outermost layer, the Stratum Corneum, also plays a vital role in supporting skin immunity.
Optimised hydration of the Stratum Corneum ensures suppleness and smoothness, while elevating barrier strength and reducing sensitivity.
These vital immunological processes, including cell-to-cell communication and physical barrier function, are supported by B-group vitamins, electrolytes and hydroscopic skin protein structures.
