To prevent infection around the lips, maintain good hygiene and protect the skin barrier. Wash your face twice daily with a gentle cleanser, and avoid touching your mouth area with unwashed hands. Dry, cracked lips are more vulnerable to infection, so keep them moisturized using a fragrance-free lip balm containing petroleum jelly, beeswax, or lanolin.

Avoid sharing personal items like lipsticks, utensils, or towels, which can spread bacteria and viruses. If you’re prone to cold sores, manage stress, use sunblock on your lips, and avoid triggers such as extreme weather or certain foods.

Be cautious with makeup—always remove it before sleeping and avoid expired products. If you shave near your lips, use clean razors and avoid nicks that can introduce bacteria. For children or people with drooling issues, gently clean the area and apply a moisture barrier.

If redness, swelling, or oozing appears, consult a healthcare provider. “Even small wounds can become infected if not cared for,” says Dr. Marie Collins, a dermatologist.

With consistent care and awareness, lip infections can often be prevented—protecting both health and comfort.
