Abstract: The present invention refers to a composition containing a) a fermented supernatant, or fractions thereof, of Lactobacillus casei or paracasei species, the species being characterized by having in their DNA genome at least one DNA sequence essentially identical to one of the sequence selected from the group consisting of: SEQ ID No 1 to 5, and b) proper carriers and/or diluents and/or excipients. The fermented supernatant is obtainable through a method characterized by the fermentation of the Lactobacillus casei or paracasei species in a minimum solution additioned with prebiotic fibers. The fermented supernatant does not have prebiotic fibers.

Abstract: The present invention refers to a composition including a fermented supernatant of Lactobacillus casei or paracasei species The species is characterized by having in its DNA genome at least one DNA sequence essentially identical to one of the sequences selected from the group consisting of: SEQ ID No 1 to 5, and proper diluents and/or carriers and/or excipients. The compositions can be used in the treatment and/or prevention of skin and/or dermatological diseases related to inflammation, allergic reactions, contact hypersensitivity reactions and intolerance, excessive sebaceous secretion, exfoliation or microbial dysbiosis, preferably of the epidermis.
