缺水

Think of the skin’s barrier like a brick wall; the barrier of dehydrated skin has gaps between bricks that allow hydration to seep out. This lack of proper hydration leads to rough texture, flaking, and itchy skin. Skincare for dehydrated skin requires two key modes of action: moisturization and skin-barrier repair. Dehydrated skin needs moisturizing ingredients like hyaluronic acid, which attracts moisture and holds up to 1,000 times its own weight in water. To reinforce the skin barrier, ingredients like ceramides, fatty acids, and beta glucan help fill in the gaps between the “bricks,” and act like mortar to form an invisible film that helps hold in moisture. Once the skin is capable of retaining moisture, itchy skin is relieved, flaking and dryness are minimized, and signs of aging like fine lines and wrinkles look less pronounced.
