Bioderma Atoderm Intensive Gel Moussant helps to strengthen the skin barrier biologically while relieving irritability, discomfort, and itching. Atoderm Intensive Gel Moussant, which is formulated with purifying agents and Vitamin PP, fights the growth of microorganisms and other irritants that exacerbate skin dryness. The Skin Barrier Therapy patent stops certain bacteria (staphylococcus aureus), which are naturally present on the skin’s surface and can cause severe dryness, from growing and forming biofilms on the skin’s surface. Regardless of skin type, the D.A.F proprietary natural complex raises the skin’s tolerance threshold to fortify its resistance.
