Obtained by the bioguided fermentation of a plant probiotic Lactobacillus arizonensis, known for its acclimation to dry desert conditions, LACTOBIOTYL^® is a postbiotic active ingredient that targets dry skin. It improves the integrity of the skin barrier by boosting the production of markers of cohesion and of protein and lipid structures. It activates epidermal renewal while preserving the equilibrium of the cutaneous microbiota. Tested on the face and hands, LACTOBIOTYL^® restores hydration and luminosity to the dry skin of Caucasian and Asian volunteers.
