Eczema in the Armpits: Causes, Symptoms & Odor Solutions

If your armpits are red, itchy, or flaky, you might be dealing with eczema. And yes, eczema can show up in your underarms. It’s more common than you think. Eczema in armpits can feel uncomfortable and confusing, especially when it messes with your daily routine. The good news? There are ways to manage it and feel more at ease in your skin.

What Is Underarm Eczema?

Eczema is a skin condition that causes inflammation, itching, and irritation. When it appears in the armpits, it’s usually called armpit rash eczema or eczema in armpits. This area is sensitive, warm, and often moist, which can make the symptoms worse. Friction, sweat, and even deodorant can trigger or irritate the rash.

There are different types of eczema, but in the underarms, it’s often contact dermatitis. That means your skin is reacting to something it touched like fragrance, alcohol, or other harsh ingredients in deodorant or soap.

Common symptoms include:

• Red or darkened patches
• Dry, flaky, or cracked skin
• Itching or burning
• Swelling or tenderness
• Peeling or weepy skin in severe cases

And yes, there can be odor too. Eczema doesn’t cause body odor, but irritation can make it harder to manage sweat and bacteria. That’s where eczema odor solutions come in.

What Causes Eczema in Armpits?

There’s no one single answer. The causes of underarm eczema can vary from person to person. For most, it’s a mix of skin sensitivity and exposure to irritants.

Common triggers for underarm eczema include:

• Fragrances and dyes: Found in many deodorants, body washes, and laundry detergents
• Alcohols and preservatives: These can dry out or inflame sensitive skin
• Sweat and friction: Heat and rubbing can make the skin barrier break down
• Allergic reactions: Nickel, latex, or even certain fabrics can cause issues
• Stress and hormones: These can lead to flare-ups, especially in people with eczema-prone skin

Sometimes, switching to a gentler routine is the first step in healing. Knowing what’s in your products helps you avoid flare-ups and stay more comfortable.

How to Treat Armpit Eczema

If you're wondering how to treat armpit eczema, the goal is to calm irritation and protect your skin’s natural barrier. That means keeping the area clean, dry, and free from harsh ingredients.

Here’s where to start:

• Stop using products that sting or burn: If your deodorant makes your armpits itch or peel, it’s time for a change
• Use a gentle cleanser: Skip the scented soaps and try a mild, fragrance-free wash
• Moisturize daily: Use a lightweight, non-greasy moisturizer to keep skin smooth and protected
• Wear breathable fabrics: Cotton and moisture-wicking materials reduce sweat and friction
• Apply anti-inflammatory creams: Over-the-counter hydrocortisone can help, but check with your doctor before using it long-term

These steps can ease symptoms and help your skin heal. But if your rash gets worse or doesn’t go away, talk to a dermatologist. You might need a prescription treatment or allergy testing to figure out what’s going on.

Natural Remedies for Underarm Eczema

Some people prefer to go natural. And that’s totally okay as long as you’re careful. Natural remedies for underarm eczema can be soothing, but not every “natural” ingredient is skin-safe. Always do a patch test first.

Safe natural options include:

• Colloidal oatmeal: Soothes itching and calms inflammation
• Coconut oil: Has mild antibacterial properties and locks in moisture
• Aloe vera: Cools and hydrates irritated skin
• Magnesium hydroxide: A gentle compound that helps neutralize odor without irritating the skin

Remember, “natural” doesn’t always mean better. Your skin knows what it likes. Pay attention to how it reacts.

Deodorant for Eczema Underarms

If you're dealing with itchy armpits eczema, your deodorant could be making it worse. The skin under your arms is thin and sensitive. That’s why choosing the right deodorant really matters.

Look for an eczema safe deodorant that is:

• Fragrance-free or lightly scented: Strong perfumes are a common trigger
• Alcohol-free: Alcohol can dry and irritate eczema-prone skin
• Aluminum-free: Some people find aluminum salts make their eczema worse
• Made with skin-soothing ingredients: Like magnesium, aloe, or shea butter

MAGS Skin offers a deodorant specifically made for sensitive skin. It uses magnesium hydroxide instead of baking soda or aluminum. That means it fights odor without damaging your skin barrier. It’s a smart option if you’re looking for a deodorant for eczema underarms.

Eczema Odor Solutions

Let’s talk about the part no one likes to mention odor. When your underarm skin is inflamed, it's harder to manage sweat and bacteria. That’s why some people with eczema in armpits notice more smell than usual.

Here are some easy eczema odor solutions that won’t irritate your skin:

• Clean gently: Use lukewarm water and a mild cleanser once a day
• Dry completely: Pat (don’t rub) your armpits dry after washing
• Use a magnesium-based deodorant: It controls odor without blocking sweat
• Change clothes after sweating: This keeps bacteria from building up on irritated skin

Odor is normal. But if it suddenly worsens or smells unusual, check with your doctor. It could be a sign of infection.
