Milia bump on the lip

Milia usually arise in surface skin, so the exact position matters: a spot on the skin above the lip is different from one on the wet inner lip. A smooth, firm, pale bump may fit milia, while [Whiteheads](/symptoms/whiteheads/) or other [Skin Bumps](/symptoms/skin-bumps/) may look similar.

Blisters, sores, tenderness, bleeding, or a bump that keeps returning need a different assessment. Do not rely on a photo or on the word milia to explain a lesion inside the mouth.

Wash gently, avoid biting or rubbing the area, and pause any product that stings. Do not squeeze or use a pin: the lip margin is delicate and injury can cause bleeding, infection, or a lingering mark. A clinician can confirm [Milia](/conditions/milia/) and discuss whether observation is suitable.

If treatment is needed, options may include a clinician-guided [Topical Retinoids](/treatments/medical-dermatology/topical-retinoids/) plan for appropriate skin or a procedure such as [Curettage And Cautery](/treatments/surgical-dermatology/curettage-and-cautery/). Do not apply prescription products to the inner lip unless specifically instructed.

Seek prompt assessment for a painful blister, open sore, bleeding that does not settle, pus, spreading redness, fever, rapid growth, or trouble eating or drinking. Arrange routine review if a firm bump remains, changes, or repeatedly returns.

Ask whether the bump is on skin or mucosal tissue, what alternatives should be excluded, whether treatment could affect the lip border, and how to care for the area afterward.
