Small white bubbles on lips

Small white spots or bubbles on the lips may be Fordyce spots, irritation, a blister, or an infection, depending on their features.

A clear bubble can be a mucus cyst from a blocked minor salivary gland, especially on the inner lower lip after lip biting. A cluster of painful blisters can fit herpes simplex, while a white patch that does not wipe away may reflect irritation, fungal overgrowth, or another mucosal lesion.

Do not pop, scrape, or burn the spots. Avoid lip biting, harsh cosmetics, and foods that sting, keep the area clean, and photograph the change so its size and duration can be compared; treatment depends on whether the clinician finds a cyst, infection, trauma, or normal anatomy.

Arrange an examination for a lesion that lasts beyond two weeks, enlarges, repeatedly returns, bleeds, becomes firm, or causes significant pain. Seek urgent care for rapidly spreading facial swelling, trouble breathing or swallowing, or swelling with fever.

Ask whether the appearance fits Fordyce spots, a mucus cyst, trauma, or infection, and whether the lesion needs testing or removal. Also ask which products and foods to avoid and what change should prompt a review.
