Eruptions on the lips, as well as the appearance of pimples on them, are not the most pleasant things. It is not only about the beauty and aesthetics of the face, but also in some cases about pain, feeling of stretched skin and redness.

There are many possible causes of acne on the lip. Usually, acne occurs due to clogged pores. If the blocked pore becomes inflamed, a pimple appears, which may contain pus.
However, acne is not an indicator of poor hygiene, and a pimple on the lip is usually not a cause for concern. The main thing is not to try to squeeze the pimple, and even more so — to pierce it with a needle. This can lead to infection, and the pimple may leave a scar.

It is not worth trying to predict the fate of a rash and wondering why a pimple on the lip “popped out” – to love or to sighing. It is better to understand the reasons for its occurrence and how to get rid of it as soon as possible.

What is a pimple?


A pimple is a small red bump that may or may not have a white or black tip. Pimples can form on any part of the body, in particular on the lips.

What causes acne on the lips?

Acne occurs when hair follicles become clogged with dead skin cells or fat, also known as sebum. Sebum passes through the hair follicles, helping to moisturize the skin and hair. When excess sebum and dead skin cells build up, they block pores and allow bacteria to grow. As a result, pimples appear.

A white pimple is formed when the wall of the follicle swells, and a black pimple (pimple) is formed when the bacteria in the clogged pores are exposed to the air.

Acne can appear at any age. Their appearance can be caused by the use of dairy products, chocolate, improper removal of makeup, use of certain medications, hormonal changes during puberty and the menstrual cycle, pregnancy and menopause in women, as well as stress.

There are a number of reasons that could cause a sudden spot, pimple or rash to appear on or around your lips. It is important to determine whether they are worth worrying about and what treatments are available if necessary.

Pimples on the lips can vary in size, appearance and accompanying symptoms. Sometimes they can be painful or unpleasant, but often they are harmless and go away without treatment. More serious causes of rashes on the lips may require medical intervention.

Let’s look at several reasons for the appearance of pimples on the lips, including cases when rashes are symptoms of diseases.


Allergies can cause rashes and pimples on the lips. The rash can be caused by an allergic reaction to pollen, pet dander, or certain foods.

Allergies can also be caused by lipstick, in particular, that which contains titanium and other aggressive chemicals. Allergic reactions occur when the immune system identifies a certain allergen as harmful, causing inflammation of the skin and lips, or even more serious reactions such as anaphylaxis.

If you notice a rash on your lips after eating certain foods or inhaling certain smells, you should consult a doctor who will prescribe tests and treatment.


If white blisters with pus appear on the inside of the lip and are accompanied by a burning or tingling sensation, it may be aphthae. Canker sores are small lesions that can develop on the soft tissues of the mouth or near the base of the gums. Canker sores are not contagious, but can be painful, especially when eating or talking.

Usually, aphthae are small and oval in shape. They can heal without scarring in just a few weeks. Large canker sores are less common, but can be extremely painful and have irregularly shaped edges. It takes up to 6 weeks for such wounds to heal, and significant scars may remain after them.

Canker sores can appear due to minor injuries to the oral cavity, as well as due to a deficiency in the body of vitamin B-12, zinc or iron. Canker sores can be caused by stress and certain foods, including coffee, chocolate, strawberries, peanuts and tomatoes, etc. The sores usually go away on their own within a week.

Consult your family doctor or dentist if your canker sores cause pain, sores that don’t go away, or spread to the outside of your lips.


A pimple on the lip can be herpes, especially if the small blisters are clustered together around the lips. Herpes is caused by certain strains of the herpes simplex virus (HSV).
Usually, with herpes, a person feels itching, burning or tingling around the lips during the day, then hardening appears, and later – several blisters filled with liquid. Over time, they can “merge” into one blister and begin to burst.
Signs and symptoms of cold sores can vary depending on whether this is a first outbreak. At the first outbreak, a person may suffer from fever, headache, pain in muscles and gums.

HFMD (hand-foot-mouth disease)

Another viral infection that can cause pimples on the lip and red spots in the mouth that turn into painful sores is hand, foot, and mouth disease (HFMD).

Symptoms of HFMD include:

  • fever;
  • loss of appetite;
  • pain in the throat and oral cavity;
  • red spots in the mouth;
  • a rash on the fingers, hands, soles of the feet, buttocks and in the groin.

HFMD is a common condition in children under 5 years of age. Although contagious, HFMD is rarely a serious illness. Most patients recover without treatment within 7-10 days.

Thrush of the oral cavity

Oral thrush, or candidiasis, is an infection caused by a yeast fungus known as Candida.

This yeast is naturally present in the mouth, but can sometimes cause problems if it grows too much.

Symptoms of oral thrush may include:

  • white spots on the tongue, throat and inner surfaces of the mouth;
  • redness and cracks in the corners of the mouth;
  • loss of taste or unusual sensation in the mouth;
  • redness and pain when eating or swallowing.

Anyone can get thrush, but people with weakened immune systems are at greater risk than others.

Fordyce granules

Fordyce’s granule is a cluster of small white or yellowish pimples that can form on or near the lips. Such a rash is not contagious and not painful. It is an enlarged sebaceous gland that naturally exists on the lips and other moist tissues, such as the inside of the mouth, cheeks or genitals, and usually disappears over time.


A mucocele is a mucus-filled mass on the lower lip, gums, or oral mucosa. Usually, mucoceles appear after an injury, for example, an accidental bite of the lip or due to a blockage of the salivary gland, which is responsible for draining saliva into the mouth. Most mucoceles go away on their own without treatment.

Perioral dermatitis

Perioral dermatitis is a common skin condition that resembles acne. People with this disease develop a small, red, bumpy rash around the mouth and chin. It is not known exactly what causes this problem, but the use of certain cosmetic creams or skin contact with water or toothpaste containing fluoride can be potential causes.

Lip contouring

A bump on the lip can also be the result of lip contouring using hyaluronic acid.

Lumps that appear within the first 72 hours after the procedure are usually the result of swelling or bruising and usually go away on their own. However, unevenness lasting longer than 72 hours may be a reaction to the filler.

If the lump does not disappear after about 2 weeks, it is better to contact the specialist who performed the procedure. They can dissolve the lip filler with an enzyme that breaks down hyaluronic acid.

When it comes to beauty and aesthetics, in particular the oral cavity, you should trust professionals and learn what aesthetic and antiaging dentistry is.

How to get rid of a pimple on the lip at home

However, in most cases, a pimple on the lip is not a sign of the disease. After a while, the pimple that bothers you should disappear.

To speed up this process:

  • wash your face at least twice a day with mild soap;
  • do not rub the affected area and do not try to squeeze the pimple on the lip;
  • avoid face creams, cosmetics and sunscreens as they can cause irritation;
  • do not smear pimples on the lips with toothpaste, as it is designed for teeth, not for sensitive facial skin;
  • eat nutritious, balanced food with plenty of vitamins and minerals;
  • drink plenty of water every day;
  • maintain good oral hygiene, brush your teeth twice a day.

A number of the following remedies can help get rid of pimples on the lips.

Tea tree oil can reduce inflammation if a pimple has appeared on the surface of the lip and stop its further development.

Aloe vera has anti-inflammatory, soothing and moisturizing properties. and can be useful for treating pimples on the lips.

Applying ice to inflammatory acne can help reduce lip swelling. However, before using ice, you should wrap it in a clean cloth or gauze and not apply ice directly to the pimple.

In order to reduce unpleasant symptoms and promote the rapid healing of acne on the lip, you can purchase an over-the-counter drug containing benzoyl peroxide at a pharmacy. This chemical works by killing the bacteria that cause acne and reduces inflammation. Products containing benzoyl peroxide can be in the form of gels, lotions, and face washes.

However, if pimples appear regularly, or a lot of them appear and they do not disappear within 4-8 weeks, you should consult a dermatologist. For multiple or recurring pimples on the lips, a dermatologist may prescribe medication, and in some circumstances even antibiotics, to kill the bacteria that cause pimples on the lips.

In some cases, laser therapy is used to treat acne, which also works on bacteria.

If nothing else helps, the doctor can remove the pimple using sterile instruments.
