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).

A potent antioxidant, it also boosts skin resilience and reduces the appearance of irritation, while increasing epidermal hydration and preventing TEWL.

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.
