Lactobacillus is a probiotic (a "good bacteria") that is beneficial for your body.
It is particularly effective for the skin, and has hydrating, soothing and balancing effects when its non-live form is used in skincare. Lactobacillus breaks down to lactic acid, a component of the skin’s natural moisturizing factor (NMF) - a group of substances that ensure moisture balance within skin.
