Cosmetic or dermatologic composition against dry and/or sensitive skin

Abstract

The present invention relates to the use of an effective amount of at least one microorganism belonging to the species Lactobacillus paracasei or casei, a fraction thereof or a metabolite thereof, in combination with an effective amount of at least one microorganism belonging to the species Bifidobacterium longum or Bifidobacterium lactis, a fraction thereof or a metabolite thereof, for producinga dermatological composition intended for treating and / or preventing reactive sensitive skin that may or may not be associated with dryness of the skin.

Description

technical field [0001] The present invention mainly relates to the use of combinations of specific microorganisms for the preparation of compositions, especially cosmetic and / or dermatological compositions, more particularly compositions for the prevention and / or treatment of sensitive and / or dry skin. The invention also relates to corresponding compositions. Background technique [0002] Usually, sensitive skin is defined by the exceptional reactivity of the skin. However, unlike allergic skin, the reactivity is not caused by an immune reaction to the presence of an allergen, ie it does not only occur on the skin that has become sensitive. Its mechanism of action is called nonspecific. [0003] The reactivity of the skin is usually manifested by the way the individual displays discomfort signals from contact with trigger elements which can be of various origins. [0004] Skin reactivity is usually manifested by the way an individual displays symptoms of discomfort to tri...
