Aqua Posae Filiformis is a unique bacterial extract obtained through biotechnology. It is made by cultivating the probiotic Vitroscilla Filiformis bacterium in a medium enriched with La Roche-Posay thermal spring water. This water contains rare trace elements such as selenium which act as a booster for the beneficial biological properties of Vitroscilla Filiformis. Once boosted, it becomes the prebiotic Aqua Posae Filiformis. The extract is obtained by fragmenting Aqua Posae Filiformis. It helps to enhance hydration, restore the skin barrier, and rebalance microbial diversity in individuals with atopic eczema/dermatitis.
