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.
