What could cause tiny bumps on the corners of my lips?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Tiny bumps near the corners of the lips are most commonly caused by three conditions: cold sores, Fordyce spots, or angular cheilitis.

Cold sores are small, painful, fluid-filled blisters caused by the herpes simplex virus.
Fordyce spots are harmless, small yellowish-white bumps made of enlarged oil glands.
Angular cheilitis appears as red, cracked, or inflamed skin at the lip corners, often linked to moisture, fungal, or bacterial infection.

Because each condition looks similar but requires different treatment, identifying the cause early helps you avoid unnecessary discomfort and choose the right care. If you're unsure what's causing your lip bumps, take a free, instant, online symptom check to better understand your symptoms and confidently plan your next steps.

Explanation

There are a few possible causes for tiny bumps at the corners of your lips.

One possibility is cold sores. Cold sores start as small, fluid-filled bumps and are caused by a virus. They can be painful and sometimes spread to other areas.

Another cause could be Fordyce spots, which are tiny, harmless bumps made up of oil glands that appear on the lips and surrounding skin. These spots do not cause pain or problems and simply need no treatment.

The third possibility is angular cheilitis, a condition where the corners of the mouth become irritated, red, and sometimes cracked. Angular cheilitis is often linked to a fungal or bacterial infection and can occur when the skin in the mouth's corners is moist or irritated.

If you notice any changes in the bumps, if they cause discomfort, or if they spread, you can use Ubie's free AI-powered symptom checker to help identify what might be causing your symptoms and learn when it's best to seek care from a healthcare provider.
