You can use professional treatments and home remedies to get rid of them. This article discusses different tips and home remedies to treat armpit rashes and prevent them. Keep scrolling!

Armpit Rashes: Types And Causes

Armpit rash can be itchy and appear red

If your armpits are itchy and appear reddish for hours or days, you may have a rash. It could be caused by an allergic reaction (to deodorant chemicals or others) or an underlying infection. Sometimes, even the skin surfaces around your armpits rubbing against each other can cause the rash.

Armpit rashes are of different types.

1. Chafing

This is the rash that occurs wherever you have skin folds, including the armpits. It is caused as a result of the skin rubbing against itself. Chafing is characterized by the following signs:

  • Redness
  • Stinging and burning sensation
  • Swelling (in severe cases, skin may crack and bleed)
  • The top layer of the skin appears rubbed off.

This is more common in summers or when you wear tight clothes.

2. Atopic Dermatitis (Eczema)

This is a chronic condition in which your skin is inflamed. It occurs mostly in the skin folds, including the armpits, areas behind the knees, and inner elbows (where the skin folds). The signs include:

  • Redness
  • Itchiness
  • Crusting
  • Bleeding (only if it is severe)
  • Oozing fluid when scratched

Eczema can also cause flare-ups several times during the year, and the rashes may last for a week or more if untreated.

A blogger shared her experience managing eczema. She first found out she had eczema in 2012 but her condition was minimal. She writes, “…but I had a few patchy rashes in specific places: around my eyes, on the side of my face, and on my neck (i).” However, her rashes kept getting worse. Talking about her most recent rash she adds, “The neck rash that developed very soon after starting the candida diet, and stopping topical steroids. It looks like two very large red angry hands wrapped themselves around my neck…There’s a very clearly outlined rashy patch on my cheek.”

The following graph displays data on the proportion of adults with eczema who said certain symptoms were the most bothersome. The result of the poll by people with eczema, those who care for people with eczema, and their spouses, partners, or family members revealed that itching was the most troublesome symptom of the condition, while anxiety and depression were considered as the least problematic symptoms.

3. Allergic Contact Dermatitis

This is your skin reacting to antiperspirantsi  Products that reduce sweat or perspiration on the skin and lessen body odor by blocking the sweat glands. or deodorants or other external allergens. The chemicals may irritate your armpits, causing redness, itchiness, small bumps, and a stinging sensation. In severe cases, you may even get blisters.

4. Seborrheic Dermatitis

This is when the excess sebum your skin produces causes patches and rashes. These usually appear oily and flaky. These rashes are more common in infants and can appear in their armpits, ears, scalp, or the face.

5. Candida

Candida is a skin infection that is most commonly caused by Candida albicans, a species of yeast. These breed in moist and warm parts of your body, including the armpits.

A study was conducted by The Centers for Disease Control and Prevention (CDC) across 45 countries in 9 states consisting of approximately 17 million people. They identified 1226 candidemia cases across the 9 states. It was estimated that there were about 22,660 candidemia cases in the US in 2017.

A sweat gland infection can lead to skin irritation and inflammation, often resulting in an underarm rash. The signs of candida include:

  • Itching
  • Scaling
  • Swelling
  • Redness and rashes

Tight clothes, hot/humid weather, or poor skin hygiene can be the contributing factors. Certain steroid creams can also exacerbate the infection.

6. Tinea Corporis (Ringworm)

Tinea corporis is a fungal infection affecting the topmost layer of your skin, causing a red rash with raised borders.

7. Erythrasma

Erythrasma is caused by bacteria called Corynebacterium minutissimum. It can affect your armpits, the groin area, and the area under your breasts. The rash looks reddish and is accompanied by a change in the skin texture. Usually, doctors treat this rash with fusidic acid or clindamycin.

The skin folds are the most common spots for an infection. But these are treatable with dermatological medications and some mild cases with effective home remedies.

Tips To Treat Armpit Rashes

When you spot a rash, visit the dermatologist first and understand the type of infection you have. The doctor may suggest medications and topical ointments (based on the type of rashes) like:

  • Hydrocortisone creams (0.5-1.0%)
  • Antihistamine medications
  • OTC calamine lotions and creams
  • Antifungal gels, creams, lotions, and spray
  • Antibacterial cream

If your armpit rash is a result of a chronic condition, like eczema, the doctor may suggest certain prescription medications including:

  • Mild steroid creams
  • Phototherapyi  A treatment that uses a specific type of UV light to reduce the inflammation associated with chronic eczema and psoriasis.
  • PDE4 inhibitorsi  A type of medication that reduces the inflammation associated with skin conditions like eczema and psoriasis.

Apart from these medications, you may also try certain home remedies for relief. Do keep in mind that these remedies do not have direct scientific research backing them up. We do not have enough studies to prove their effectiveness in treating armpit rashes.

2. Topical Vitamin B12

3. Ice Cubes

Placing ice cubes on the skin can have a numbing effect. You can also relieve itchy rashes by applying ice cubes to them. The resultant relief can also keep you from scratching the rashes and aggravating them.

Citrus extracts or pomace (whatever remains after pressing and extracting the juice and pulp) are shown to have antibacterial and antimicrobial activities (3). You may apply citrus (orange or lemon or any citrus fruit) juice or extracts on the affected area.

To use citrus extract, extract the pulp or juice of any citrus fruit and mix it with water. Apply to the affected area. You may rub the leftover pulp on the affected area. Leave it on for a few minutes and then wash with plain water.

Preventing Armpit Rashes

1. Practice Good Hygiene

Take a bath regularly using a mild shower gel. After bathing, dry yourself thoroughly. Even if you are using a towel, try to air dry the body folds before you dress up.

2. Know What Irritates Your Skin

It can be a particular deodorant or a roll-on antiperspirant or any other personal care product. If you notice that a specific product or ingredient (such as products containing alcohol) is giving you rashes, stop using it right away.

3. Avoid Tight Clothes

Wearing tight clothes made of synthetic fabric may often cause armpit rashes. Such clothes cannot allow sweat to escape, making it accumulate in the armpits. Wear soft fabrics made of cotton. They let your skin and armpits breathe.

4. Use Anti-Chafing Powder

The rashes you develop in your armpits are more often just heat rashes. They occur when the weather is hot and humid. Applying anti-chafing powder to your armpits keeps your skin from rubbing against itself. You can also try staying in a cool, air-conditioned place more often.

Proper care can keep rashes from worsening and also prevent them. If not, they may develop into a chronic rash. Please visit your doctor if you experience the following:

  • Rashes accompanied by high fever
  • Blisters on the affected area
  • Rashes spreading to other parts of the body
  • Swelling and pain in the affected area
  • Rashes that ooze pus, blood, and fluid
  • Rashes that do not respond to home remedies and OTC medicines
  • Rashes that are tender, swollen, and red
  • Rashes accompanied by vomiting, nausea, and dizziness
