Eczema Underarms: Causes, Symptoms & Solutions

Itchy, red, and irritated armpits can make even the simplest daily routines uncomfortable. If that sounds familiar, you might be dealing with eczema underarms. This common skin condition can show up as a rash, dryness, or flaking under your arms. And while it’s frustrating, you’re not alone and there are ways to calm it down.

What Is Eczema Under the Arms?

Eczema underarms is a type of eczema that shows up in the armpit area. It’s also called atopic dermatitis. This condition causes your skin to become inflamed, dry, and very itchy. Under your arms, it can feel especially sensitive because the skin there is thinner and often exposed to sweat, friction, and products like deodorant.

Unlike a regular rash, eczema tends to come and go. You might have flare-ups when your skin is triggered by something, then periods where it starts to heal. Understanding your triggers is key to managing symptoms and finding relief.

What Does Eczema Underarms Look and Feel Like?

It’s not always easy to tell if you have eczema rash under armpits or something else, like a heat rash or allergic reaction. Here are some common signs of underarm eczema:

• Red, dry, or scaly patches
• Extreme itchiness (especially at night)
• Cracked or peeling skin
• Darkened or thickened skin over time
• Burning or stinging sensation

If your armpits feel sore, itchy, and irritated for more than a few days, it’s a good idea to talk with a dermatologist. Getting the right diagnosis is the first step toward relief.

What Causes Eczema Under Arms?

There’s no single cause of eczema, but there are several things that can trigger a flare-up. When it comes to what causes eczema under arms, these are some of the most common culprits:

• Deodorants and antiperspirants: Many products contain alcohol, fragrance, or aluminum, which can irritate sensitive skin
• Friction: Constant rubbing from clothing or skin-on-skin contact can break down the skin barrier
• Sweat: Trapped moisture and heat create a perfect storm for eczema
• Allergies: Contact dermatitis from ingredients in laundry detergent or deodorant can cause an itchy rash
• Genetics and immune response: If eczema runs in your family, your skin may naturally react more strongly to triggers

Identifying your personal triggers is important. Keep track of what products you use and when symptoms show up. That can help you spot patterns and make changes.

How to Treat Eczema Under Arms

If you’re wondering how to treat eczema under arms, the good news is there are simple steps that can make a big difference. The goal is to reduce irritation, calm inflammation, and strengthen your skin barrier. Here’s how:

1. Switch to a Deodorant for Eczema Underarms

Regular deodorants can be harsh. If you have eczema, look for a deodorant for eczema underarms that’s made without alcohol, fragrance, baking soda, or aluminum. These ingredients can dry out or inflame already sensitive skin.

The best deodorant for sensitive underarms uses gentle ingredients like:

• Magnesium hydroxide: Helps stop odor without blocking sweat or irritating skin
• Aloe vera: Soothes and hydrates delicate underarm skin
• Plant oils: Like coconut or jojoba to nourish and protect

If you’ve ever experienced an underarm rash from deodorant, making the switch to a skin-friendly formula can help prevent future flare-ups.

2. Build a Simple Eczema Skincare Routine

Consistency is key when it comes to managing itchy armpits eczema. A good eczema skincare routine for your underarms should focus on three things: cleansing gently, locking in moisture, and avoiding triggers.

Here’s a sample routine:

• Cleanse: Use a mild, fragrance-free cleanser once a day. Avoid scrubbing the area.
• Moisturize: Apply a fragrance-free moisturizer or barrier cream after showering. Look for ingredients like ceramides, shea butter, or squalane.
• Protect: Wear breathable, loose-fitting clothes to minimize friction and sweat buildup.

Stick to products labeled for sensitive skin. And always patch test new products before using them fully.

3. Calm Active Flare-Ups

When eczema flares up, you need fast relief. For stubborn rashes, your doctor may recommend:

• Over-the-counter hydrocortisone cream
• Prescription topical steroids or non-steroid creams
• Antihistamines to reduce itching

But remember: these are short-term fixes. Long-term healing comes from understanding your triggers and supporting your skin barrier daily.

When to See a Dermatologist

If your underarm eczema keeps coming back or doesn’t improve with gentle care, it’s time to see a dermatologist. They can help confirm the cause and recommend a personalized treatment plan. You may be dealing with a different skin condition like a fungal infection, psoriasis, or a contact allergy that mimics eczema.
