Armpit Pimples vs. Ingrown Hairs: How to Tell the Difference
Not sure if that bump in your armpit is a pimple or an ingrown hair? You’re not alone. The underarm area is sensitive and prone to all kinds of skin issues. And when a bump shows up, it can be painful, red, and confusing. Is it a zit? A trapped hair? Something more?
Armpit Pimple vs Ingrown Hair: Why It Matters
Knowing the difference between an armpit pimple and an ingrown hair helps you treat it the right way. If you pop or scrub the wrong type of bump, you could make things worse. That means more pain, more inflammation, and even infection.
Let’s break down the difference between armpit pimples and ingrown hairs. We’ll also walk through what causes each one, how to treat them, and when to see a doctor.
What Is an Armpit Pimple?
An armpit pimple is just like a pimple you’d get on your face or back. It’s a clogged pore. Dead skin, oil, and bacteria build up and form a red, swollen bump. Sometimes it fills with pus. Sometimes it just hurts.
Common causes of armpit pimples include:
- Excess sweat and oil
- Friction from tight clothes
- Bacteria from dirty razors or deodorants
- Hormonal changes
Your underarms stay warm and damp, which makes them the perfect place for clogged pores. Add in shaving, deodorant, and rubbing fabric, and it’s no surprise that pimples pop up.
What Is an Ingrown Hair Under the Arm?
An ingrown hair happens when a hair grows back into the skin instead of out of it. It can cause a painful red bump that looks a lot like a pimple. But it’s not caused by oil or bacteria. It’s caused by a trapped hair.
Here’s how to tell if it’s an ingrown hair or pimple: look for a dark spot in the center. That’s often the hair. You might also notice the bump is more firm and doesn’t have a whitehead.
Ingrown hairs are often caused by:
- Shaving too close
- Curly or coarse hair that grows sideways
- Dead skin clogging the follicle
- Wearing tight or non-breathable fabrics
An ingrown hair under the arm bump can get infected if you pick at it or try to dig it out. That’s why it’s important to know what you’re dealing with before trying to get rid of it.
Armpit Bumps Identification: Key Differences
So how do you figure out if it’s a pimple or an ingrown hair? Start with what it looks and feels like. Here’s a quick comparison:
| Feature | Armpit Pimple | Ingrown Hair |
|---|---|---|
| Appearance | Red bump, may have whitehead | Firm bump, often with visible hair |
| Pain Level | Can be tender or sore | Often sharp or itchy |
| Cause | Clogged pore from oil and bacteria | Hair trapped under skin |
| Location | Anywhere in the armpit | Usually near shaved areas |
Painful Bump Under Armpit Not Pimple: What Else Could It Be?
If the bump is painful but doesn’t fit either description, it might be something else. Sometimes, swollen lymph nodes, cysts, or infections like hidradenitis suppurativa can cause underarm bumps. These need a doctor’s attention.
As a rule of thumb, if a bump keeps getting bigger, doesn’t go away, or is extremely painful, talk to your healthcare provider.
How to Treat Armpit Pimples
If you’ve figured out it’s a pimple, here’s what to do:
- Clean the area gently: Use a mild cleanser that won’t strip your skin.
- Skip the deodorant for a day or two: Let your skin breathe while it heals.
- Apply a warm compress: This helps reduce swelling and bring the pimple to a head.
- Use a spot treatment: Look for ingredients like salicylic acid or tea tree oil.
Don’t pop it. That can push bacteria deeper into the skin and make things worse.
Underarm Ingrown Hair Treatment
If it’s an ingrown hair, the treatment is a little different:
- Gently exfoliate the area: This helps remove dead skin and free the hair.
- Use a warm compress: It can soften the skin and make it easier for the hair to break through.
- Apply an ingrown hair serum: Look for ones with glycolic or lactic acid to help loosen the hair.
- Don’t tweeze or dig: That can lead to infection or scarring.
If the bump gets worse or starts to ooze, see a healthcare provider. You may need a prescription cream or antibiotic.
How to Prevent Armpit Skin Bumps
Good news: most armpit bumps can be avoided. Here’s how to keep your underarms clear and calm:
- Switch to a gentle deodorant: Harsh ingredients can irritate the skin and clog pores.
- Shave smart: Use a clean razor and shave in the direction of hair growth.
- Exfoliate weekly: This helps prevent both pimples and ingrown hairs.
- Wear breathable fabrics: Let your skin breathe to reduce sweat and friction.
Your underarms don’t need a 10-step routine. Just a little care goes a long way.
Quick Takeaways
- Armpit pimples are clogged pores caused by oil, sweat, and bacteria.
