Bacterial Skin Infections are very common skin problems. Human skin acts as a good barrier against bacteria but many bacteria can easily come in contact with the skin as well as stay on the skin. This condition makes skin vulnerable for bacterial infections. Bacterial Skin Infections usually start with small bumps or redness on the skin and slowly increase over the time. Some bacterial skin infections are easily treatable and curable while some bacterial skin infections are harmful causing life threatening diseases.

Many types of bacteria can infect the skin but the most common types are Staphylococcus and Streptococcus. Dermatologist is a skillful skin specialist who treats and cures complex bacterial skin infections.
