Bioderma Atoderm PP Baume Ultra-Nourishing Balm 200ml Bioderma Atoderm Ultra Nourishing Balm has been specifically formulated for those with very dry and sensitive skin. The Bioderma Atoderm Balm soothes the skin with a balm feel, rather than your usual moisturiser to penetrate the skin for long lasting hydration.  How to use: Apply a pea sized amount to the target area and gently massage onto dry and clean skin.      Add more if needed.
