Yes, the dermis does store water.
The dermis, the layer of skin beneath the epidermis, plays a crucial role in the body's water storage. Blood vessels within the dermis supply nutrients to the skin, and this layer also acts as a reservoir for a significant portion of the body's water. This water is essential for maintaining skin hydration and overall physiological functions. The epidermis relies on the dermis for nutrients and hydration to generate new cells. Essentially, a well-hydrated dermis contributes to healthy and vibrant skin.
