Bioderma Atoderm Cream Ultra (500ml) provides the same intensive hydration and skin barrier restoration as the 200ml version in a larger, value-sized pack. Infused with niacinamide, shea butter, and glycerin, it nourishes extremely dry skin, reduces irritation, and strengthens the skin’s natural protective barrier. Ideal for long-term daily use, it ensures skin remains soft, supple, and comfortable, effectively preventing dryness, tightness, and discomfort even in harsh conditions.
