Your dermis is the layer of skin that's just underneath the part you can see and touch. The dermis is full of capillaries, sweat glands, and hair follicles.
The Greek derma, or "skin," is at the heart of both epidermis, "outer skin," and dermis, "true skin." It's probably your epidermis you think about most — especially when it's itchy or sunburnt. But the thick dermis layer plays a vital role in cushioning the body, giving us a sense of touch, allowing us to feel heat, and much more.
