Our skin is the interface between our inner world and the outer world. It is subject to different aggressions (pollution, stress, food) that alter its balance. However, some skins are more sensitive to these stresses. Skin sensitivity affects today more than 60% of us: the skin becomes more reactive, with redness, patches, tightness, itching, which are visible or invisible discomfort. Provide and maintain comfort is a priority for its well-being. A balanced skin is a sublimate and healthy skin.
