A persistent sore on the lip won’t heal in a few weeks. Most minor cuts or irritations heal much faster. When a pimple persists, it could be a sign of an underlying health problem. The skin on the lips is very sensitive, making it prone to infection and irritation.
Persistent pimples can look different from person to person. They may be small, red, and inflamed, or they may appear as larger, crusty patches. It’s advisable to pay attention to any changes in size, color, or feel. Observing other symptoms such as pain, itching, or swelling can also help determine the cause.
