A pimple inside your nostril is almost always an infected hair follicle, and the fastest way to get rid of it is with warm compresses applied three times a day for 10 to 15 minutes each session. Most nostril pimples clear up within a week or so with basic home care, but some need a prescription antibiotic ointment, and a small number signal an infection that shouldn’t be ignored.
What’s Actually Happening Inside Your Nose
The inside of your nostril, called the nasal vestibule, is lined with tiny hairs and hair follicles. When bacteria get into one of those follicles, it swells up into what looks and feels like a pimple. This is technically called nasal vestibulitis, and it’s usually caused by staph bacteria that already live on your skin.
Common triggers include picking your nose, plucking nose hairs, blowing your nose too aggressively, or having a recent cold that left the skin inside your nostrils raw and cracked. Dry winter air can also irritate the lining enough to let bacteria in. You’ll typically notice tenderness first, then a visible bump, and sometimes yellow crusting or scabbing around the opening of your nose or along the septum. Mild cases itch. More inflamed ones throb.
Warm Compresses: Your Best First Step
Warm, moist heat is the most effective home treatment. It increases blood flow to the area, helps the bump drain naturally, and reduces pain. The American Academy of Dermatology recommends soaking a clean washcloth in hot water and holding it against the pimple for 10 to 15 minutes, three times a day. If the bump is deep inside the nostril, you can fold a small corner of the washcloth and gently press it just inside the opening. Reheat the cloth when it cools down so you get the full benefit of each session.
Don’t squeeze the pimple. The veins in your nose drain toward your brain, which means forcing bacteria deeper into the tissue carries real risks (more on that below). Let the compress do the work. Most small bumps will soften, drain on their own, or shrink within five to seven days of consistent warm compresses.
What to Put On It (and What to Avoid)
Standard acne products like benzoyl peroxide and salicylic acid are designed for external skin and can badly irritate the delicate mucous membrane inside your nose. Skip them entirely. The same goes for common over-the-counter antibiotic ointments that aren’t formulated for nasal use, as they can contain ingredients that irritate the nasal lining.
If warm compresses alone aren’t enough after a few days, the go-to treatment is a prescription antibiotic ointment specifically designed for use inside the nose. It’s applied twice a day, morning and evening, for five days. Your doctor can prescribe it after a quick look at the bump. A thin layer of plain petroleum jelly can also help keep the area moist between compress sessions and prevent cracking that lets bacteria back in.
Signs the Infection Is Getting Worse
Most nostril pimples are minor annoyances. But the blood vessels inside and around your nose connect to a network of veins that runs behind your eyes and toward your brain. In rare cases, an untreated bacterial infection in this area can cause a blood clot in those deeper veins, a condition called cavernous sinus thrombosis. This typically shows up five to ten days after an infection that hasn’t been treated.
Red flags that mean you need medical attention promptly:
- The bump keeps growing or turns into a firm, painful boil
- Fever develops alongside the nasal bump
- Swelling spreads to the bridge of your nose, cheek, or around your eye
- Vision changes like blurring or seeing double
- Intense headache that worsens over hours
These complications are uncommon, but they’re serious enough that delaying care isn’t worth it. A course of oral antibiotics can usually stop the progression.
How to Prevent Nostril Pimples From Coming Back
If you get these repeatedly, the cause is almost always something introducing bacteria into the hair follicles on a regular basis. The biggest culprits are nose picking and aggressive nose hair removal. Plucking or waxing nose hairs pulls the entire follicle, leaving an open wound that bacteria can colonize easily. The Ohio State University Wexner Medical Center recommends using small scissors (cuticle or embroidery scissors work well) to trim protruding nose hairs instead. Cutting the hair leaves the follicle intact and dramatically lowers your infection risk.
A few other habits that help: keep your fingernails short, wash your hands before touching your face, and apply a small amount of petroleum jelly inside your nostrils during dry weather to prevent the cracking and irritation that makes infections more likely. If you use nasal sprays regularly, wipe the nozzle clean before each use. People with frequent nosebleeds or chronic nasal dryness are more prone to vestibulitis and benefit most from keeping the area moisturized.
