Dysbiosis

Imbalance of the microbial ecosystem (intestinal or cutaneous) characterised by reduced microbial diversity, decreased beneficial bacteria (such as Faecalibacterium prausnitzii) and increased pro-inflammatory bacteria. Intestinal dysbiosis is associated with acne, eczema and psoriasis via the gut-skin axis. Cutaneous dysbiosis (dominance of Staphylococcus aureus) is characteristic of atopic dermatitis.
