Each day, emotional and environmental stresses affect skin's barrier function, one of its self-defense capacities. Thus, skin tends to dehydrate, to become more sensitive and uncomfortable: imperfections appear. Lancome creates Hydra Zen: 24-hour hydration to help protect the skin from signs of stress. Hydration is one of the first steps in any beauty routine to preserve skin's appearance. Designed to help fight the visible signs of stress, Hydra Zen provides intense hydration for skin to feel soothed and comfortable. A comfortable texture with a delicate and relaxing fragrance, ideal for combination skin.
