Types of Armpit Rashes

Contact Dermatiti

You experience Contact Dermatitis when you yourself by chance come into contact with some allergen or irritant.

You might not believe it, but even the fragrance of the lotion or any deodorant you use can potentially result in contact dermatitis in your armpits. Even the fabric of your new shirt or a laundry detergent has the capability to cause contact dermatitis.

Atopic Dermatitis

Eczema or atopic dermatitis generally begins at the time of childhood. It is the most common rash you can have, including the insides of your elbows, backs of the knees, other folds including the armpits. It’s normally itchy and red. 

Many times people end up bleeding from the eczema rashes as a result of continuous scratching due to intense itching. Normally, skin looks calm and composed until some certain times of the year that actually flare-up the eczema experience.


Candida, also known as candidiasis is more of a fungal or yeast infection. It occurs mostly in wet or moist areas, such as underarms. Candida can cause:

  • Swelling
  • Scaling
  • Red rashes
  • Itching  

Candidiasis gets worse in hot weather conditions, under congested clothing, or due to low hygiene. Much different from other kinds of rashes, candida rashes are better treated by antifungal creams. Steroid creams can even worsen fungal infections like these. 

Seborrheic Dermatitis

Seborrheic dermatitis is another type of skin irritation targeted by high rates of production of sebum, or some skin oils. Caused by the oils, it can be seen generally as oily areas of scales and flakes unlike the dry patches of eczema. These flakes get yellow due to high amounts of oil glands.  

Infants face a kind of seborrheic dermatitis, generally called cradle cap. This usually arises and easily visible on the scalp, face, ears, and armpits of children.

Treating Armpit Rashes

The above-discussed conditions can be lead to or targeted by different substances that come into contact with your skin.

Finding the irritant

For solving the armpit rash, determine the irritant and discontinue its use from that very moment. This will cure eczema, contact dermatitis, and many seborrheic dermatitis flare-ups.

What you can do?

Removing the irritants is an essential step. Armpit rashes can be further soothed by:

  • Using cool compresses
  • Take a warm bath (it should not be hot) mixed with colloidal oatmeal
  • Use over-the-counter anti-itching creams
  • Using unscented moisturizers on dry skin and cases of eczema

Dare to Scratch

I know it’s hard, but please try avoiding scratching the infected area. Scratching opens up the pores and makes your skin more prone to infections due to dirt and other dust particles. These medications might help you get rid of itching to some extent:

  • Try taking Allegra or Claritin during the day times. These both are antihistamines and easily available over the counter.
  • At the night, a simple antihistamine like Benadryl can cure itching and also helps you with your sleep issues.

Stay Calm and Relax

Psychologically proven, stress essentially worsens some dermatitis types. Different kinds of relaxation techniques will definitely help in fighting the rash. It will also keep you from scratching and fighting temptations.  

Remedies to cure an Armpit rash

Home Remedies

There are many ingredients at home that will help you treat your armpit rashes.

  • To solve itching, place some ice cubes or ice packs on to the rash.
  • Cut a lemon and slide that against the skin of your armpit. The citric acid in the lemon will kill the bacteria present in your armpits and it can also be used as a DIY deodorant.
  • Focus on consuming more vitamin C from natural sources such as oranges, broccoli, and tomatoes for fighting against skin issues

Essential oils including coconut, lavender, or tea tree oils help cure itchiness, irritation, and varieties of fungal infections.

You can mix a small quantity of lavender and coconut oils and spread the mixture over the affected skin with some cotton swab.

Again, some cotton swabs can be used to kill fungus and extra itchiness by using tea tree oil thoroughly mixed with some amount of water.

Over-the-counter Remedies

Calamine lotion and Hydrocortisone cream are one of the most efficient treatments at home for armpit rash-causing irritation and inflammation.

Fungal rashes such as candida rash are meant to be treated with different methods. You need to try some antifungal over-the-counter ointments that contain clotrimazole, ketoconazole, or nystatin.

Any cream or lotion that contains these ingredients should help with candida like armpit rashes. But, keep in mind that, steroid creams such as hydrocortisone creams will eventually worsen fungal rashes.

Anti-chafing powders also give relief to the armpit rashes. These powders might not help you cure fully or get rid of the rash completely, but they will make you bear the rash irritation and itching for sure. Powders will be effective in reducing the pain and irritation that originated due to our skin rubbing against itself in the armpit.

Dilemma of Armpit rashes 

Armpit rash, no matter intense or normal, can get worse if left untreated. These can even lead to bacterial or some serious fungal complications. These types of infections can further give rise to fluid-filled red-colored bumps generally known as pustules. Pustules are very itchy and can get very inflamed upon scratching. Too often scratching and peeling off the skin leads to permanent scars.

Different symptoms signaling to bacterial infections can include:

  • Warmth
  • Tenderness
  • Swelling
  • Redness

Other serious complications can occur if you don’t treat the actual underlying causes of these rashes. You might need to get some prescription treatment or a skin biopsy if the rash doesn’t disappear itself after some time.

How to prevent Armpit Rash?

The primary factor you can focus on to avoid armpit rashes is good hygiene, and we all know what does that means. Keep the body clean, shower regularly, and try getting air-dry rather than using a towel.

If you feel that some specific products such as skincare things or deodorants are causing rashes, stop applying them immediately. If you are not able to find certain reasons for the rashes, go see a medical practitioner. He might help you better in finding the cause of the rashes. 

Some of the possible assumptions are like the tight clothing that you wear might be the reason. The sweat can’t escape out of the tightness and can give rise to a number of bacteria, eventually infections and rashes.

Try wearing loose, cotton clothes that give your armpit breathing space so that sweat doesn’t stay in your armpits.

Not every time it is a severe rash, sometimes it can be a simple heat rash, that will automatically get better after one to two days. You can also use the cool talcum powders in hot weather conditions that will prevent the heat rashes essentially. Staying in cool, well air-conditioned places will play a primary factor in stopping rashes.

What can you do?

If the rash doesn’t get better with over-the-counter or home remedies in two to three days, you should consult your doctor.
