Optimal skin hydration is crucial to maintain soft, flexible, smooth skin—and to preserve a youthful appearance. Water levels of our skin mainly depend on the health of our skin barrier (stratum corneum, the outermost epidermal layer of the skin), and is influenced by exposure to sunlight, pollution, and stress.
Our epidermis has two different layers of hydration within it. Water present in the deeper layer goes upward to hydrate cells in the stratum corneum, which can be easily evaporated due to the environment and improper cleansing techniques. When your skin is hydrated and the barrier is working well, skin appears more radiant, luminous and healthy-looking.
