Cellulitis is an infection of the skin caused by bacteria. It can occur anywhere on your body, and the area that is most commonly affected is your lower legs. Cellulitis usually occurs when bacteria enter the skin through a crack or break into your skin and invade the area under the skin. Skin infections can also occur when bacteria are introduced into the skin through insect, spider, or animal bites. There are different types of skin infections. Some skin infections may look raised and swollen, others may look like red bumps on the skin, while others may even have pus. In general, some symptoms of cellulitis may include:

  • Redness to an area
  • Swelling
  • Warmth
  • Tenderness
  • Pain

With minor surface wounds, there are steps you can take at home to prevent a more serious infection such as cellulitis. However, if a wound is slow to heal or starts to have a lot of the symptoms of cellulitis listed above, you may need to go see a provider.

Skin infections are a common cause of hospitalization: up to 3.5 million hospitalizations in 2005. It is important to take good care of any wounds to prevent skin infections.

Risk Factors for Developing Skin Infections

Certain diseases or medical problems may increase your risk of having skin infections.

  • Injury: cuts, fractures, burns, or scrapes give bacteria an entry point under your skin
  • Weak immune system: conditions such as diabetes, leukemia, and HIV can weaken your immune system and make you more at risk for infection
  • Skin conditions: conditions such as eczema and athlete’s foot can cause skin breaks and give bacteria an entry point

Hygiene and Prevention

1. Wash hands with warm soap and water if you touch the wounded area. 2. Properly clean the area with soap and water and cover any open cuts or scrapes with a bandage to prevent bacteria from entering the wound. 3. If your skin is dry, use moisturizing creams, lotions, or ointments to prevent your skin from cracking. 4. Avoid sharing personal hygiene items such as hairbrushes, razors, facecloths, and towels, and regularly keep your personal hygiene items clean. 5. Avoid scratching open wounds. 6. Avoid swimming in unclean or untreated water if you have an open wound.

Over the Counter Topical Antibiotics

You can buy antibiotic creams or ointments at the drugstore. They are commonly used on minor scrapes and wounds to prevent infections. Creams and ointments may be appropriate to use in different situations:

  • Creams: Usually easier to apply and spread over a larger area. They are better to use in wet or “weeping” skin injuries.
  • Ointments: Can be very greasy and give an oily feeling to the skin. Ointments should not be used if the wound is oozing. It is better to use an ointment on dryer wounds.

When you walk into a first aid aisle at your local drugstore, you may be overwhelmed with several different products. Some common items you may see are:

Brand Name Active Ingredients
Betadine First Aid Antibiotics + Moisturizer Ointment or Polysporin Ointment/Powder Polymyxin B + Bacitracin
Gold Bond First Antibiotic Ointment Polymyxin B + Bacitracin + Neomycin + Pramoxine
Neosporin Ointment Polymyxin B + Bacitracin + Neomycin
Neosporin Plus Pain Relief Cream Polymyxin B + Neomycin + Pramoxine

Directions for use:
- Wash your hands before and after use
- Clean affected area and dry well before application
- Put a small amount and rub in gently
- Cover with dressing

These antibiotic creams and ointments can be used for minor cuts, scrapes, and burns. They generally work very similarly on wounds. If you have any allergic reactions, such as rash, to one of the ingredients, you should read the drug facts label to pick a product that does not contain it, and report your allergy to your provider. Remember that if using a product makes the wound look worse or more irritated, you should stop using it and see your provider.

When should you see your provider immediately?
- If you have a wound that has other things stuck in it
- If your wound is from an animal or human bite
- If you have signs of infection: fever, chills, continued or increased pain or swelling, or oozing fluid from the wound
- If a wound does not improve within five days
