Pre- and probiotics for human skin.

Current research on the complex interplay between the microbiota, the barrier function and the innate immune system of the skin indicates that the skin's microbiota have a beneficial role, much like that of the gut microflora. As a consequence, interest in strategies beyond antibiotica that allow a more selective modulation of the skin microflora is constantly growing. This review will briefly summarize our current understanding of the cutaneous microbiota and summarize existing information on pre- and probiotic strategies for skin.
