Skin, the largest organ. Is your epidermis showing? Don't worry, it should be. Your epidermis is the top part of your skin, and your skin is your body's largest and fastest-growing organ. Skin is your body's coat. It protects you. Doctors who are experts in caring for skin are called dermatologists. Derma is the Greek word for skin. Dermatologists treat just about everything that can happen to skin, including rashes, dry skin, acne, and skin cancer.
