The Research
The skin has its own immune system, with specialised tissues and cells playing a vital role in preventing environmental damage, allergy and disease. The concept of skin immunity and beauty are exquisitely linked, with a healthy, resilient skin reflected in a clear and even complexion. The vital processes of cell-to-cell communication and skin barrier function are supported by B-group vitamins and the phospholipid-protein structures of skin’s outermost layer, the Stratum Corneum.

The Resilience Actives

– Vitamin B3 (Niacinamide/Nicotinamide) boosts skin resilience and strengthens barrier function, helping skin to protect itself against sun damage while also calming the appearance of redness and irritation. This Skin Identical vitamin also promotes evenness of tone by inhibiting the transfer of melanosome units through the layers of the epidermis, and locks in moisture by preventing Trans-Epidermal Water Loss (TEWL).
– Ascorbyl Glucoside is a stable form of Vitamin C bonded to the glucoside component which reduces the appearance of pigmentation to even out skin tone. A potent antioxidant, it also boosts skin resilience and reduces the appearance of irritation, while increasing epidermal hydration and preventing TEWL.
– Ceramides + Amino Acids amplify epidermal hydration by fortifying natural barrier function, as well as promoting skin firmness and elasticity. Australian Botanicals have the potential to reduce the appearance of erythema and boost natural solar defence mechanisms to help protect cells against sun damage.
– Acetyl Octapeptide-3 is a specialised protein which boosts skin resilience by activating Langerhans Cells and supports skin’s repair processes. Adenosine Triphosphate provides a vital source of cellular energy to optimise intercellular communication within the skin, and encourages healthy barrier function.
