Cellulitis is a bacterial infection of the deepest layer of your skin. Bacteria can enter your body through a break in the skin – from a cut, scratch, or bite. Usually if your skin gets infected, it’s just the top layer and it goes away on its own with proper care. But with cellulitis, the deep skin tissues in the infected area become red, hot, irritated and painful. Cellulitis is most common on the face and lower legs.
