What is a facial boil? Is it true that a painful pimple inside your nose is dangerous if popped? - Mona Clinic

Have you ever been surprised by a red, swollen, throbbing bump on the tip of your nose or inside your nostril? Many people worry, "Is this just a normal pimple? Or is it a boil?" Bumps around the nose can carry a risk of worsening depending on their location, and attempting to squeeze them yourself is particularly dangerous. This article, based on medical information, provides an easy-to-understand explanation of what a boil (mencho) is, its difference from a pimple inside the nose, its causes, dangers, what not to do, and when to seek medical attention.

What is a mencho? The difference from pimples inside the nose

"Mencho" is an old Japanese term referring to a painful, red, swollen bump or boil that appears on the face. Medically, it is considered similar to a "furuncle" (setsu) or "folliculitis," a condition where bacteria infect the hair follicle deep within the pore, causing pus to accumulate. Bumps that appear specifically on or around the nose are often conventionally called mencho.

While seemingly similar, common acne (acne vulgaris) and mencho have slightly different origins. The differences are summarized as follows:

Most instances of what people perceive as "a pimple inside the nose" are actually folliculitis caused by bacteria entering the hair follicles on the inner wall of the nostril. The nose is a delicate area with nasal hair, making it prone to bacterial entry and pain.

Causes of mencho and nasal pimples, and proper treatment for faster healing

Bumps around the nose are more likely to occur due to a combination of the following factors:

• Bacterial infection, such as Staphylococcus aureus: Commensal bacteria are present on the skin and inside the nose. When the skin barrier is damaged, bacteria can enter the hair follicle and cause inflammation.
• Habit of touching or rubbing the nose: Stimuli such as touching or picking the inside of the nose with fingers can create small wounds, making it easier for bacteria to enter. Hands carry many bacteria.
• Self-removal of nose hair: Plucking or deeply trimming nose hair can damage hair follicles and skin, often triggering folliculitis.
• Excess sebum and clogged pores: The nose has many sebaceous glands, and sebum and dead skin cells tend to accumulate there. Clogged pores can lead to pimples and inflammation.
• Physical condition and lifestyle: When the immune system is weakened due to lack of sleep, stress, or fatigue, infections can worsen more easily.

When you feel "nasal pimple pain," it can sometimes be a sign of advanced bacterial infection rather than just clogged pores. The more severe the pain and swelling, the deeper the inflammation may have progressed.

Causes of nose pimples and correct treatment for faster healing

The cause of nose pimples is not singular; it is believed to result from a combination of excessive sebum secretion, clogged pores, and bacterial attachment from the fingers. The nose is an area of the face where sebaceous glands are concentrated, making it prone to sebum oxidation and dead skin cell accumulation that can block pores. Humidity and friction from masks, as well as seasonal changes, are also known factors that contribute to nose pimples.

We often receive questions like, "Is there any fast-acting way to cure nose pimples?" Unfortunately, there is no magic solution that can make them disappear overnight. However, there are basic care practices you can do at home to prevent worsening and promote faster recovery.

• Don't touch or squeeze: Even just reducing the number of times you touch it can prevent unnecessary bacterial attachment and irritation. This may seem like a roundabout way, but it's the fastest route in the long run.
• Wash gently to keep clean: Wash twice a day with lukewarm water and a mild cleanser, without scrubbing. Over-washing can lead to dryness and be counterproductive.
• Protect the barrier with moisturizer: When skin dries out, it can become sensitive and produce excessive sebum. Maintain moisture with a gentle moisturizer.
• Improve sleep and nutrition: Lack of sleep and an unbalanced diet can delay recovery. Improving your physical condition is a subtle but sure way to boost healing.
• Gently remove makeup and sunscreen: Leftover residue can lead to clogged pores. However, scrubbing is forbidden.

While the desire for an "instant cure" is natural, the area around the nose is sensitive to irritation. Instead of rushing into aggressive self-care, maintaining cleanliness and moisture to calm inflammation will ultimately lead to the fastest recovery. If the pain or swelling doesn't subside after a few days, consider consulting a medical professional as it may be time to reassess your self-care.

Understanding bumps on different parts of the nose (tip, side, nostril, inside)

Although all are referred to as "nose bumps," the underlying causes and points of concern can vary slightly depending on their location. Here, we organize the general understanding for each area. Please use this as a guide to calmly assess the condition, not for self-diagnosis.

Pimples on the tip of the nose

Pimples on the tip of the nose tend to appear in areas with particularly many sebaceous glands. Pores can become clogged with sebum and dead skin cells, causing red swelling. While noticeable, it is important not to touch or squeeze them, and to maintain cleanliness and moisture.

Pimples on the side of the nose

The side of the nose (the ala, or wing of the nose) is an area where sebum tends to accumulate, and where residue from washing or makeup can easily remain. Mask friction can also be a factor. If pimples on the side of the nose recur, it may be an opportunity to review your washing and moisturizing methods and check for excessive rubbing.

Bumps in the nostril or inside the nose

Red bumps that appear at the entrance of the nostril or inside the nose are often not so much pimples as folliculitis caused by bacteria entering the hair follicles. The inside of the nose is close to the mucous membrane and delicate, and it is prone to injury from nose hair removal or picking, which can cause pain. If a "bump inside the nose" is painful, doesn't heal easily, or recurs, it's safer to consult a medical institution rather than relying too much on self-care, precisely because it is a mucous membrane area.

Why is it dangerous? Know the "danger triangle" of the face

The most important thing to know about bumps around the nose is the "danger triangle" of the face. This refers to the triangular area connecting the corners of the mouth and the bridge of the nose. The nose, upper lip, and inside of the nose are all included in this range.

The veins in this area have a characteristic connection to the "cavernous sinus" near the brain. Therefore, if a mencho or bump inside the nose is forcibly squeezed or irritated, and bacteria enter the bloodstream, it can, though rarely, lead to the spread of infection deep within and severe complications. While very rare, it is an area where the risk is not zero, so careful handling is crucial.

If you experience any of the following symptoms, do not simply observe it as a regular pimple, but consider seeking medical attention promptly:

• Severe pain or swelling that is rapidly spreading
• Accompanied by fever, malaise, or headache
• Swelling around the eyes or difficulty seeing
• Redness is spreading over an increasingly wide area

These could be signs of worsening condition. Do not hesitate to consult a medical institution.

What you absolutely must NOT do

While it's tempting to touch a bump on your nose, please avoid the following actions as they can worsen inflammation or spread infection:

• Squeezing or draining pus yourself: Especially squeezing a mencho in the danger triangle can push bacteria deeper. Avoid squeezing facial blemishes yourself.
• Picking with a needle or tweezers: Unhygienic tools can lead to new infections.
• Plucking nose hair or touching excessively: This further damages hair follicles and prolongs inflammation.
• Aggressive self-care methods: Scrubbing vigorously, repeatedly applying alcohol, etc., can damage the skin barrier and be counterproductive.

The desire for a "quick fix" is very natural. However, not irritating it and keeping it clean is ultimately the fastest way to recovery.

Can over-the-counter medications provide care? Know their limitations.

If the symptoms are mild and consist of only a small red bump, they may resolve by maintaining cleanliness and observing the situation. Over-the-counter topical medications containing antibacterial ingredients may be an option, but there are a few caveats:

• Using over-the-counter medications inside the nose (near the mucous membrane) may not be appropriate for self-treatment.
• If the cause is a bacterial infection, over-the-counter medications alone may not be effective enough, making improvement difficult.
• If there is no improvement or if the condition worsens after a few days of use, it is time to consider the limits of self-care.

Over-the-counter medications are only a temporary option for mild cases. If the pain is severe, the swelling is large, or it recurs, a proper diagnosis and treatment at a medical institution will provide reassurance.

Furthermore, regardless of whether they are over-the-counter or prescription, avoid using topical steroids (such as Locoid) for mencho without medical supervision. Steroids suppress the immune system, so using them for mencho caused by bacterial infection can actually worsen the condition.

Medication for mencho and the approximate healing process

The medication used for mencho varies depending on the cause and symptoms. Since bacterial infection is often the underlying cause, medical institutions may use topical or oral antibiotics depending on the symptoms. Over-the-counter medications are only a temporary option for mild redness or swelling, used while maintaining cleanliness, and may not be suitable for inside the nose or for severe pain. As the appropriate medication varies depending on the condition, it is safer to consult a doctor rather than choosing medication yourself if the pain or swelling is severe.

We also receive many questions like, "How long does it take for a mencho to heal?" or "I want to know the healing process." While highly individual, the general progression of inflammation resolving can be as follows. There are large individual differences, and it does not always follow this exact course:

• Initial stage: A red bump appears, and it feels painful or warm when pressed. Keep it clean without irritating it.
• Peak stage: Swelling and pain intensify, and pus may accumulate in the center. It's tempting to squeeze it, but it's crucial not to touch it at this stage.
• Recovery stage: Inflammation subsides, and swelling and pain gradually decrease. Pus may drain naturally or be absorbed, and redness fades.

During recovery, redness or marks may remain for a while. Conversely, if swelling or pain intensifies daily, pus spreads, or the healing process does not begin, it may be a sign that the condition is not improving. In such cases, do not continue to observe it; consult a dermatologist or other medical institution nearby.

When to seek medical attention and dermatological treatment

In the following cases, we recommend consulting a dermatologist or an online clinic:

• Severe pain, swelling, or heat that interferes with daily life
• No improvement or worsening after several days
• Accompanied by systemic symptoms such as fever or spreading redness
• Recurrent bumps on the nose or hairline

At a dermatology clinic, treatment with antibiotics (topical or oral) may be provided depending on the symptoms. If pus has accumulated and formed a lump, a procedure to drain the pus in a sterile environment may be considered. In either case, it is crucial to proceed under a doctor's diagnosis, not self-diagnosis. For pimples on the hairline or recurrent folliculitis, discussing skincare and lifestyle habits can help prevent worsening and recurrence.

Is "death by mencho" real? Correctly understand severe complications.

Some of you may have seen terms like "mencho death" online and become anxious. First, it's important to know that mencho itself is often a condition that resolves with proper management. There's no need to be excessively afraid.

However, it is also true that severe complications are known to occur very rarely. The nose and upper lip are located in the "danger triangle" of the face, and the veins in this area are connected to the cavernous sinus near the brain. If a mencho is forcibly squeezed and bacteria enter the bloodstream, it can, albeit rarely, lead to a serious condition called "cavernous sinus thrombosis." In an era before effective antibiotics, such severe complications could be life-threatening, which is why the saying "mencho is scary" has persisted.

Today, with antibiotic treatment available, such severe complications are extremely rare. While there's no need for excessive fear, the key to minimizing risk is simply "not squeezing or picking" and recognizing the following signs:

• Severe headache or high fever
• Swelling around the eyes or feeling like your eyes are protruding
• Visual disturbances such as double vision or difficulty seeing
• Rapidly spreading redness and swelling

These are signs of potential severe complications. If any apply, do not wait; seek medical attention promptly. By understanding correctly and acting appropriately, there's no need to be unduly frightened.
