The skin is the largest organ of the human body, and is also its protective coating. It helps you stay cool when it’s hot, and stay warm when it’s cold. The skin also keeps all your insides in place, from your muscles, blood, to your other organs such as the lungs and heart. It also keeps foreign material out such as water and bacteria, unless the skin gets damaged or cut. You also feel the sense of touch through the nerves in your skin. Dermatologists are the doctors who specialize in the study and care of the human skin. They know how to and can effectively treat any skin condition or disorder that may arise such as skin cancer, acne, eczema, blackheads, rashes, dryness, and more.
