# 9 Sneaky Causes of White Bumps on Lips Dermatologists Want You to Know
White bumps on the lips range from harmless to bothersome, and dermatologists say identifying the cause matters for proper care.
Fordyce spots rank among the most common culprits. These small, painless white or yellowish bumps form on the lips and inside the mouth due to enlarged oil glands. While completely normal and present in up to 70 percent of people, they're purely cosmetic concerns requiring no treatment.
Milia represent another frequent cause. These tiny cysts form when dead skin cells become trapped beneath the skin's surface. They appear as white or cream-colored bumps and typically fade without intervention, though some people opt for professional extraction.
Cold sores caused by the herpes simplex virus create painful fluid-filled blisters that eventually form white crusts. These bumps differ from other lesions because they tingle, burn, and produce visible fluid. Antiviral medications like acyclovir can reduce symptoms if taken early.
Keratosis pilaris, a common skin condition affecting hair follicles, occasionally appears on lips as small, rough bumps. This benign condition doesn't require treatment but responds to moisturizing routines and gentle exfoliation.
Mucous cysts form when salivary glands become blocked or irritated. These larger bumps contain clear fluid and may feel soft and moveable. Some resolve independently, while others need professional drainage if they persistently interfere with eating or speaking.
Less common causes include lichen planus, an autoimmune condition creating white lacy patterns on lips. Oral thrush, a fungal infection, produces white patches and requires antifungal treatment. Allergic reactions to lip products, foods, or medications can trigger temporary swelling and
