Why Am I Getting Pimples in My Armpits?

If you've ever looked in the mirror and thought, "Why am I getting pimples in my armpits?" you're not alone. Those small, painful bumps under your arms can feel confusing and frustrating. But don't worry. There's a reason for those underarm breakouts, and better yet, there are ways to treat and prevent them.

What Causes Pimples in Your Armpits?

Pimples in your armpits often come from the same things that cause acne on your face: clogged pores, bacteria, and irritation. But because the armpit is a warm, moist area with lots of movement, it’s especially prone to breakouts.

Here are the most common armpit acne causes:

• Clogged pores under armpits: Sweat, dead skin cells, and product buildup (like deodorant) can block your pores.
• Bacterial infection in armpits: When pores get clogged, bacteria can grow and turn into red, painful bumps.
• Sweat glands pimples: Overactive sweat glands can trap moisture, leading to inflamed bumps or even cysts.
• Friction and shaving: Shaving can irritate the skin and cause ingrown hairs or cuts that lead to infection.
• Armpit folliculitis: This is when hair follicles get inflamed, often due to bacteria or shaving.

Understanding what’s going on under your skin is the first step to clearer, calmer pits.

Is It Acne, Folliculitis, or Something Else?

Not all bumps under armpits are the same. Some might be simple pimples. Others could be armpit folliculitis or even a sign of something more serious. Here's how to tell the difference:

• Regular pimples: Small, red bumps that may have whiteheads. Usually caused by clogged pores and bacteria.
• Folliculitis: Looks like acne but happens when hair follicles get infected, often after shaving or sweating.
• Boils: Larger, painful lumps caused by deep bacterial infection. These may need medical treatment.
• Hidradenitis suppurativa: A chronic skin condition that causes painful lumps in sweat glands. If your bumps keep coming back, talk to a doctor.

If the bumps are painful, spreading, or not going away, it's worth checking in with a dermatologist.

Why Do I Get Pimples in My Armpits?

Let’s break it down. Your armpits have sweat glands and hair follicles, just like your scalp or face. They're also warm and often covered by clothing, which creates the perfect environment for breakouts.

Here are some common triggers:

• Heavy sweating: Traps bacteria and dead skin inside pores.
• Deodorant residue: Can build up and clog pores if not washed off properly.
• Tight clothing: Causes friction and traps moisture, which irritates the skin.
• Shaving without protection: Can lead to tiny cuts or ingrown hairs that turn into pimples.
• Hormones: Just like with facial acne, hormone changes can trigger underarm breakouts.

Once you understand your triggers, you can start to make small changes that help prevent future breakouts.

How to Treat Underarm Pimples

The good news is you don’t have to suffer in silence. There are simple and effective underarm pimples treatment options that can help soothe your skin and stop new pimples from forming.

1. Cleanse Gently but Thoroughly

Use a mild, fragrance-free cleanser to wash your underarms daily. Look for products with ingredients like salicylic acid or glycolic acid, which help remove dead skin cells and unclog pores.

2. Exfoliate (But Not Too Much)

Exfoliating once or twice a week can help prevent clogged pores under armpits. Use a gentle scrub or a chemical exfoliant. Avoid over-scrubbing, which can irritate the skin and make things worse.

3. Choose the Right Deodorant

Some deodorants contain ingredients that can clog pores or irritate sensitive skin. Look for formulas that are:

• Aluminum-free
• Fragrance-free or low-fragrance
• Designed for sensitive skin

MAGS Skin deodorants, for example, use gentle ingredients like magnesium to neutralize odor without blocking your pores or irritating your skin.

4. Treat Bumps with Targeted Ingredients

For existing pimples, try spot treatments with:

• Benzoyl peroxide: Kills bacteria and reduces inflammation.
• Tea tree oil: A natural antibacterial option (just dilute it before applying).
• Warm compresses: Can help soothe painful bumps and encourage healing.

5. Avoid Shaving Over Irritated Skin

If your armpits are already breaking out, give them a break. Shaving can make irritation worse and spread bacteria. Use a clean razor and a moisturizing shave cream when you're ready to shave again.

How to Prevent Future Breakouts

Once your skin clears up, keep it that way with a few smart habits:

• Shower after sweating: Don’t let sweat sit on your skin for too long.
• Wear breathable fabrics: Cotton and moisture-wicking materials allow airflow and reduce friction.
• Switch deodorants if needed: If your current product causes bumps, try a gentler one.
• Keep razors clean: Replace them often to avoid bacteria buildup.

Remember, consistency is key. Gentle daily care helps keep your skin balanced and breakout-free.

When to See a Dermatologist

If your underarm pimples are large, painful, or keep coming back, it might be time to talk to a dermatologist. You may be dealing with a deeper bacterial infection in your armpits or a skin condition like hidradenitis suppurativa.

A doctor can help diagnose the issue and recommend treatments like prescription creams, antibiotics, or other therapies that go beyond over-the-counter options.
