Abstract
The skin is the human body’s largest organ and also the first line of defence against invasive microorganisms. Though several microorganisms come in contact with or live on the skin, they are ordinarily unable to cause an infection. Environmental factors like sun exposure, chemicals, and pollution, compromise this skin barrier allowing microorganisms to enter and cause infection. Similarly, trauma through accidents, surgery or burns can result in infection. When bacterial skin infections do occur, they can range from mild to serious and potentially life-threatening. Mild infections can be treated with over-the-counter (OTC) medications and some proven home remedies, whereas more serious infections will need to be referred to the doctor.
