Small Lip Bumps That Don't Itch: What Causes Them and Are They Dangerous?
Small lip bumps that don't itch are most often caused by one of two harmless conditions: Fordyce spots, which are normal oil glands that show on the lip as white-yellow dots 1–3 mm across, and a lip mucocele, a soft, clear, pale-blue bump that forms when a tiny salivary gland duct is blocked or torn. Neither is contagious, and neither is a sexually transmitted infection.
However, a lip bump can also be an early cold sore, a wart, molluscum contagiosum, a blood-vessel bump, or, in older adults with long sun exposure, an early sign of lip cancer. This article tells the bumps apart by colour, size, softness and how long they last, explains which can be left alone and which should be seen within a few weeks, and describes how doctors treat them.
Look at three things first: colour, softness and duration
Before guessing the cause, check these three things. They narrow down the cause more than half the time.
White-yellow, several small dots, smooth, painless, present for months or years: usually Fordyce spots, or milia (small white cysts)
Clear, soft, pale blue, collapses when pressed, on the inside of the lower lip: usually a mucocele
Small clear blisters in a cluster, with tingling or burning 6–24 hours beforehand: usually a cold sore
Rough, cauliflower-like surface, or a shiny bump with a dimple in the middle: a wart or molluscum contagiosum
Dark purple-blue, soft, fades when pressed: a venous lake
Hard, scaly, or a sore that has not healed after 3 weeks, bleeds easily: needs to be checked for lip cancer
Fordyce spots: white-yellow dots on the lip
Appearance: small white or pale yellow dots 1–3 mm across, in groups of a few dozen on the edge of the upper lip, the inner lip or the inside of the cheek. The surface is smooth, not itchy and not painful, and they show more when the lip is stretched.
Cause: they are normal oil glands (sebaceous glands) sitting where there are no hair follicles. They are not an infection. They are found in about 70–80% of adults and become more visible after the teenage years because hormones make oil glands grow larger.
Seriousness and urgency: not dangerous, not contagious and not a cause of cancer. No treatment is needed if they do not bother you, and most last permanently.
When to see a doctor: if you are not sure they are Fordyce spots, if one dot grows quickly, becomes hard or turns into a sore, or if you want treatment for cosmetic reasons.
Are Fordyce spots a sexually transmitted infection?
This is a very common question, because Fordyce spots can also appear on the genitals. The answer is no. Fordyce spots are a normal part of the skin. They are not passed on by kissing or sex, and your partner does not need to be tested. Helpful clues that set them apart from infections: Fordyce spots are all about the same size, evenly arranged, do not form sores or weep, and do not change over weeks. Cold sores, by contrast, break open into sores and heal in 7–10 days, and warts slowly grow and have a rough surface.
Do not squeeze or pick at them. The oil inside does not all come out, and the lip can become inflamed, sore or darkened.
Lip mucocele: a soft, clear bump that collapses when pressed
Appearance: a round, raised bump 2–10 mm across, clear, soft, pale blue or skin-coloured, painless. It is most often on the inside of the lower lip (more than 70% of cases). It may burst by itself, releasing a clear sticky fluid and collapsing, but swells up again within a few days.
Cause: a minor salivary gland under the lip has a torn or blocked duct. This often follows accidental lip biting or chewing, a knock, or a sharp tooth, so saliva leaks and collects under the lining. It is most common in children and people aged 10–30.
Seriousness and urgency: not dangerous and not cancer. Some small ones disappear on their own within 3–6 weeks, but one that keeps coming back in the same place usually does not go away for good because the gland is still damaged.
When to see a doctor: if the bump lasts more than 4–6 weeks, bursts and returns, grows big enough to get in the way of eating or speaking, or is a firm bump that does not flatten when gently pressed.
Blocked salivary gland on the lip: how do doctors treat it?
A mucocele that does not go away on its own is treated with a minor procedure under local anaesthetic, taking about 15–30 minutes. The commonly used options are:
Surgical removal of the cyst together with the minor salivary gland causing it (surgical excision): the standard method, with a low chance of coming back because the damaged gland is removed too. 2–4 dissolving stitches are used, and the wound heals in 7–10 days.
Carbon dioxide laser (CO2 laser): cuts or vaporises the cyst with little bleeding, and often needs no stitches. Suitable for small to medium bumps.
Freezing with liquid nitrogen (cryotherapy): used for small bumps. It may need 2–3 sessions, 2–3 weeks apart.
Simply draining the fluid is not recommended: the bump flattens for a while but comes back within a few days in almost everyone.
After surgery you may feel slight numbness of the lip near the wound for 2–4 weeks. Stop the habit of biting or chewing the lip to lower the chance of new ones forming. In children, or with a large cyst under the tongue, the doctor may refer you to an oral surgeon.
Small hard white bumps at the lip edge (milia) and pimples at the lip edge
Appearance: milia are round, hard white bumps 1–2 mm across just under the skin, with no opening, not red and not painful, on the lip edge or the skin around the mouth. A pimple at the lip edge, on the other hand, is red, swollen and sore, with a pus head, and settles within 5–7 days.
Cause: milia form when keratin gets trapped under the skin. They occur after skin injury, with heavy creams, or for no clear reason. Pimples come from a blocked hair follicle together with inflammation.
Seriousness and urgency: both are harmless. Milia can last several months but may fall away by themselves.
When to see a doctor: if you want milia removed, the doctor opens the skin with a sterile needle and presses them out, which takes a few minutes. If a bump you think is a pimple has not settled after 2 weeks, have a doctor check that it really is a pimple. Read more about milia, small white bumps under the skin
Small clear blisters in a cluster on the lip: think of an early cold sore
Appearance: 6–24 hours before the blisters appear, you feel tingling, stinging or burning at the same spot on the lip edge. Then small clear blisters 1–2 mm across appear in a cluster on a red base. Within 2–3 days they break into shallow sores and form a crust, healing in 7–10 days. The blister stage may not itch, which confuses many people.
Cause: herpes simplex virus (type 1) that stays dormant in nerve ganglia and flares up with too little sleep, fever, strong sun, stress or menstruation.
Seriousness and urgency: it spreads by direct contact with the blisters or saliva, especially from the blister stage until the crust forms. Avoid kissing, do not share cups or lip products, and do not kiss babies.
When to see a doctor: antiviral medicine works best when started within the first 24–48 hours. The doctor may prescribe valacyclovir 2 g twice a day for 1 day, oral acyclovir, or 5% acyclovir cream applied 5 times a day for 4–5 days. If you get them more than 6 times a year, the doctor may consider continuous suppressive medicine. For details, read what causes cold sores. If a sore has opened and does not look like a cold sore, see what causes lip sores.
Warts on the lip: rough bumps that slowly grow
Appearance: raised skin-coloured or grey-white bumps with a rough, cauliflower-like surface, 2–8 mm across. Some are long finger-like growths (filiform warts). They usually appear on the lip edge or the corner of the mouth, and are not itchy or painful.
Cause: the wart virus (human papillomavirus), spread by contact. In children it often comes from biting nails or sucking fingers that have warts.
Seriousness and urgency: not dangerous, but it can spread and can pass to people close to you. Some clear on their own within 1–2 years.
When to see a doctor: when a wart grows or increases in number. Doctors usually treat with liquid nitrogen freezing every 2–3 weeks, 2–4 sessions in all, or with electrocautery or CO2 laser. Do not use strong salicylic acid wart paint meant for hands and feet on your lips yourself, because the lining of the mouth is thin and chemical burns can result. Read more about what causes warts
Molluscum contagiosum near the mouth: shiny bumps with a dimple in the middle
Appearance: round, skin-coloured or pearly white bumps with a shiny surface, 2–5 mm across, with a tiny dimple in the middle, appearing in groups around the mouth, face or trunk. Common in children aged 1–10 years.
Cause: the molluscum contagiosum virus, spread by skin contact or by sharing towels.
Seriousness and urgency: not dangerous. Most clear on their own within 6–12 months, and some take up to 18 months.
When to see a doctor: if the bumps multiply quickly, become red and inflamed, or if an adult has many of them. Doctors treat by scraping them off (curettage) or freezing. Read more about molluscum contagiosum
Purple-blue bump on the lip (venous lake)
Appearance: a soft, dark purple or blue bump 2–10 mm across, usually on the lower lip, that fades when pressed because the blood is pushed out. Seen in adults over 50 with long sun exposure.
Cause: tiny veins widen in skin that has aged from accumulated sun exposure.
Seriousness and urgency: it is not cancer, but it can look like a mole or melanoma, a type of pigmented skin cancer. If the colour does not fade when pressed, a doctor must examine it.
When to see a doctor: to confirm the diagnosis with a dermatoscope, or if the bump bursts and bleeds often. Doctors can treat it with a vascular laser, electrocautery or minor surgery.
Fast-growing red bump that bleeds easily (pyogenic granuloma)
Appearance: a bright red lump with a glossy, raw-looking surface, 3–10 mm across, which grows within 2–4 weeks and bleeds heavily with the slightest touch.
Cause: small blood vessels overgrow after a minor injury. It is common in pregnant women and in people taking certain medicines, such as the acne medicine isotretinoin.
Seriousness and urgency: not cancer, but it bleeds repeatedly and seldom goes away on its own (except some that appear during pregnancy and may shrink after delivery).
When to see a doctor: within 1–2 weeks. The doctor will scrape it off and stop the bleeding with electrocautery, and send a tissue sample to confirm that it is not cancer.
Hard bump, scaling or a sore that will not heal: rule out lip cancer
Appearance: early squamous cell carcinoma of the lip often starts with a lower lip that is chronically dry with white scale and an indistinct lip border (actinic cheilitis), and then a hard bump, a rough surface, or a shallow sore that crusts over again and again and has not healed after 3 weeks. It may bleed when rubbed.
Cause: decades of accumulated sun exposure, smoking, fair skin and weakened immunity. It is most common in men over 50 who work outdoors.
Seriousness and urgency: if found early and removed completely, results are very good, but left alone it can spread to the lymph nodes in the neck.
When to see a doctor: a bump or sore on the lip that has not healed within 3 weeks should be seen by a doctor for a biopsy, a minor procedure under local anaesthetic. Read more about squamous cell skin cancer
Lip bumps in children: how they differ from adults
Mucocele is common in school-age children who bite their lips.
Molluscum contagiosum and warts are seen in children more than in adults.
Clear blisters or mouth sores together with bumps on the palms and soles and a fever in a child under 5: think of hand, foot and mouth disease. See a doctor and keep the child home from school for 7 days.
A first cold sore in a child may bring a high fever, several mouth sores and refusal to drink. See a doctor within 24 hours because of the risk of dehydration.
Fordyce spots are uncommon in young children and usually become noticeable in the teenage years.
Quick comparison of lip bumps
Fordyce spots: white-yellow, 1–3 mm, several dots, smooth, permanent, not contagious
Mucocele: clear and soft, 2–10 mm, inside the lower lip, flattens then swells again, not contagious
Milia: white and hard, 1–2 mm, no opening, not inflamed, not contagious
Cold sore: clustered clear blisters, tingling beforehand, heals in 7–10 days, contagious
Warts: rough, slowly growing, contagious
Molluscum contagiosum: shiny, dimpled, seen in children, contagious
Venous lake: purple-blue, fades when pressed, older adults, not contagious
Pyogenic granuloma: bright red, fast-growing, bleeds easily, not contagious
Lip cancer: hard, scaly, or a sore that has not healed after 3 weeks, not contagious but needs to be checked promptly
Can Fordyce spots be treated if I want them gone?
Fordyce spots do not need medical treatment, but if they affect your confidence, a dermatologist has options that can make the dots smaller or fainter. Results vary from person to person and they may come back.
Retinoid creams such as tretinoin 0.025–0.05%: apply a thin layer at bedtime and use continuously for 8–12 weeks before judging the result. It helps slightly to moderately and may make the lips dry and peel. Do not use during pregnancy.
Carbon dioxide laser (CO2 laser): vaporises the oil glands one dot at a time, usually needing 1–3 sessions. Temporary redness or darkening may occur for 2–6 weeks.
Removing the gland with a tiny punch tool (micro-punch): suitable for clearly raised dots. The wound is small, about 1–2 mm, and heals in 1–2 weeks.
Isotretinoin tablets: they shrink oil glands, but the dots usually return when the medicine is stopped and there are many side effects, so doctors do not use it as a first choice for Fordyce spots alone.
Every procedure carries a risk of scarring, pigment changes and results that fall short of expectations. It should always be assessed and carried out by a doctor.
Looking after yourself when you have a lip bump
Do not squeeze, pick or pierce the bump yourself, especially a mucocele or Fordyce spots.
Stop biting or chewing your lips. If a sharp tooth or braces cut the lip, ask a dentist to adjust them.
Wear a lip balm with SPF 30 or higher outdoors to lower the risk of sun damage to the lip skin.
If you suspect a cold sore, use separate lip products and cups, and avoid kissing until the crust has completely gone.
Photograph the bump every 1–2 weeks so the doctor can see whether it is growing or changing.
If the bump appeared after changing lipstick or toothpaste and it stings or itches, stop that product first. It may be contact dermatitis.
What not to do with a lip bump
Do not pierce the bump with a sewing needle or any non-sterile needle, which risks bacterial infection and scarring.
Do not put steroid cream on a bump of unknown cause, because if it is a cold sore or a wart, steroids can make it spread.
Do not put wart remover or strong acid on the lips.
Do not leave a hard bump or a sore that has not healed after 3 weeks without having it checked.
Do not conclude that it is a sexually transmitted infection from pictures online. Most lip bumps are not in this group.
When to see a doctor and what the doctor will check
See a dermatologist if any of the following applies
The bump has lasted more than 4–6 weeks, or burst and returned in the same place
The bump is hard, growing fast, changing colour, bleeding easily, or is a sore that has not healed after 3 weeks
You are over 50, smoke or work outdoors, and your lower lip is chronically dry and scaly
Clustered clear blisters come with fever, swollen lymph nodes or keep coming back
You are not sure what it is and you are worried
The doctor will ask about duration, lip biting, sun exposure and smoking, then examine the lip by eye and with a dermatoscope. Most cases can be diagnosed straight away without further tests. If the bump looks unclear, the doctor takes a small 2–4 mm tissue sample for pathology, with results in 7–14 days.
Quick summary
Most small, non-itchy lip bumps are Fordyce spots (normal oil glands, white-yellow dots 1–3 mm) or a mucocele (a soft clear bump on the lower lip).
Neither is contagious, neither is a sexually transmitted infection, and neither turns into cancer.
Clustered clear blisters with tingling beforehand are a cold sore, which is contagious. Antiviral medicine works best when started within 24–48 hours.
A mucocele that keeps coming back is treated to stay away by surgically removing the minor salivary gland, not by draining it.
Do not squeeze, pick or apply wart remover to the lips yourself.
A hard bump or a sore that has not healed after 3 weeks needs a doctor to rule out lip cancer.
Frequently asked questions about lip bumps
What can cause small bumps on the lip that don't itch?
The most common cause is Fordyce spots, which are normal oil glands that look like several white-yellow dots 1–3 mm across, painless and permanent. Next is a mucocele from a blocked minor salivary gland, a soft clear bump on the lower lip that flattens and then swells again. It could also be milia, warts, molluscum contagiosum, or an early cold sore that has not yet broken open. If the bump is hard, grows quickly or is a sore that has not healed after 3 weeks, see a doctor.
What are Fordyce spots, and are they contagious?
Fordyce spots are oil glands sitting in an unusual place on the lips, inside the cheeks or on the genitals. They occur in about 70–80% of adults. They are not an infection, so they are not passed on by kissing or sex, and they do not turn into cancer. Treatment is not necessary, but if they affect your confidence a doctor may use retinoid creams, CO2 laser, or removal of the gland with a tiny punch tool. Results differ from person to person.
Can a blocked salivary gland on the mouth go away by itself?
Some small mucoceles from a blocked minor salivary gland clear on their own within 3–6 weeks, especially once you stop biting the lip. But if the bump bursts and returns in the same place, the gland is still damaged and it usually will not go away for good. Draining it helps only briefly. The methods that best lower the chance of it coming back are surgically removing the cyst together with the causing gland, or using CO2 laser, under local anaesthetic.
A bump on the mouth that looks like a pimple: what is it?
If the bump is red, swollen and sore with a pus head at the lip edge and settles within 5–7 days, it is probably a real pimple. But if it is a hard white dot with no head, not red and present for months, it may be milia or Fordyce spots. Several small red bumps around the mouth that spare the lip edge may be perioral dermatitis, which is treated differently from acne. If tingling or stinging came first and then turned into clear blisters, think of a cold sore. Do not squeeze it, because the infection can spread.
What are the early signs of lip cancer?
Early lip cancer usually appears on the lower lip. It starts with dry lips, chronic white scale and an indistinct lip border, then a hard bump, rough surface, or a shallow sore that crusts over repeatedly and has not healed after 3 weeks. It may bleed when rubbed. It is most common in men over 50 with long sun exposure or who smoke. If found early and removed completely, results are very good, so see a doctor for a biopsy right away if you notice these signs.
Can I squeeze or pierce a clear bump on my mouth myself?
You should not squeeze or pierce it yourself. With a mucocele, piercing makes it flatten for a while but it usually swells back within a few days and risks infection. With a cold sore, squeezing spreads the virus to the surrounding skin and onto your hands, and from there to your eyes. Fordyce spots cannot be squeezed out and doing so inflames the lip and leaves dark marks. The safer way is to have a doctor identify the type of bump and choose the treatment that fits the cause, which is usually quick under local anaesthetic.
