Your skin is the largest organ of your body. Its function is to protect your body from infection. Sometimes the skin itself becomes infected. Skin infections are caused by a wide variety of germs, and symptoms can vary from mild to serious. Mild infections may be treatable with over-the-counter medications and home remedies, whereas other infections may require medical attention. Read on to learn more about skin infections and what to do if you have one.
Your skin is your body’s largest organ. It has many different functions, including covering and protecting your body. It helps keep germs out. But sometimes the germs can cause a skin infection. This often happens when there is a break, cut, or wound on your skin. It can also happen when your immune system is weakened, because of another disease or a medical treatment.
Like an onion, your skin has layers. When it comes to infections, usually the deeper it is, the worse it can be. The first layer (epidermis) makes cells and gives you color. The second (dermis) makes oils to protect the skin and sweat to cool you. Its nerve endings help you feel heat, cold, and pain. The third layer (subcutaneous fat) attaches skin to muscles and bones, and helps control your temperature.
