What Could a Red Spot on My Lip Without a Blister Indicate?

A red spot on your lip that does not come with a blister could be a sign of actinic cheilitis. This is a condition caused by long-term exposure to the sun, especially on the lower lip. When your lip is repeatedly exposed to sunlight, the skin can become rough, and a red or white patch may develop over time. Although actinic cheilitis itself usually does not hurt or cause blisters, it is important to watch it closely because, in some cases, it can change and lead to more serious changes in the lip’s skin. Other possibilities include a small, harmless blood vessel near the surface or slight inflammation from minor irritation. If you observe that the red spot is growing, changing shape, or becoming more painful, it is a good idea to visit a healthcare provider. They can examine your lip carefully and may recommend treatment or further steps to protect your skin from the sun.
