Impetigo Signs, Symptoms and Causes

Pustules, usually, are not too large, although in neglected variants they have all the chances to unite, covering the great areas of the skin, repeating the appearance of flat bubbles. As soon as they are opened, emphasizing the purulent contents, the skin becomes covered with a thick crust. After treatment, scarring does not remain, because impetigo affects only the superficial layers of the skin.
