Bioderma Sensibio Defensive Serum 30ml combines a soothing action with anti-aging benefits. This serum was formulated in fact as an anti-aging solution specifically for sensitive and sensitized skin! Skin sensitivity can be induced by external factors such as pollution, stress, and temperature variations, which, in turn, can lead to premature skin aging signs: fine lines and wrinkles, dehydration, and dullness. With this in mind, sensitive skin needs a product that targets skin aging at the same time it targets sensibility. For this purpose, this fragrance-free formula features mostly protective ingredients.
