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.
