No More Itchy Armpits: Top 10 Underarm Rash Treatments

No More Itchy Armpits: Top 10 Underarm Rash Treatments

Our armpits can be pretty sensitive and are susceptible to dermatological conditions. One of which is itchy armpits or armpit rash that can sometimes be very painful. If you notice bumps or swelling, changes in the skin color and dryness in texture that is usually accompanied by red bumps that look like pimples, a sensation of soreness and often intense itching, with blisters and white patches and skin flaking if left untreated, then you probably have one.

Constant sweating and a bacterial or fungal infection generally lead to an underarm rash. This is understandable given a large number of blood vessels, sweat glands and lymph nodes in the underarm area, making the proliferation of itchy issues twice as likely to happen.

Types and Causes of Armpit Rash

The four commonly known types of armpit rash are brought by different factors ranging from localized conditions that are caused by eating habits, some personal and/or household items and even stress to larger infections that need a proper medical consultation. This is where the treatment may vary.

  1. Atopic dermatitis or simply known as eczema, a condition that frequently starts during childhood, is frequently found in the folds of our body like the inside of elbows, the back of our knees, and obviously in the armpits. Eczema rashes, aside from appearing red and being itchy, are inclined to skin crusting. Scratching it all the time may cause itchy armpits to bleed. The thing with this condition is that some people’s skin may appear healthy at first, only to suffer from bouts of atopic dermatitis.
  2. Seborrheic dermatitis, on the other hand, triggers itchy armpits and skin irritation when there is an over secretion of skin oil, termed as sebum. The skin becomes oily, creating flakes or scales that are white or yellow. The overproduction of sebum can also affect your ears, scalp and mostly your face.
  3. Contact dermatitis, the easiest to detect, is due to an allergen. When it leads to underarm rash, try to be more careful and critical of the ingredients in the products you are using, such as in deodorants, lotions, or even in washing powder and fabric softeners that you use for your clothes.
  4. Candida, lastly, is the last type of armpit rash that comes from a fungal or yeast infection in moist areas of the skin. Those who sweat heavily should be more careful with this one, exacerbated all the more with a hot weather, wearing tight-fitting outfits and poor hygiene. The underarm appears red or white, scaly, feels itchy and can result in swelling. There are available antifungal creams though as a treatment.

Itchy armpits, despite not being somewhat uncommon, can be triggered instead in many ways. As mentioned, this takes in hygiene issues; reactions to allergens, deodorants and other products; pregnancy for women and other pre-existing medical conditions; and even something as simple as our shaving practices.

No More Itchy Armpits: Top 10 Underarm Rash Treatments

Top 10 Underarm Rash Treatments

Aside from a bad odor, complications brought by underarm rash include high body temperature, a discoloration of the underarm, and swelling of the throat. If you are still free from these symptoms but feel vulnerable to developing armpit rash or are already having one, worry no more, underarm rash treatment not just in the form of over-the-counter medicines but also via home remedies from natural ingredients found in your kitchen, along with simple habits can greatly help you get rid of your pesky itchy armpits.

Hot or Cold Compression

Hot and Cold Compress

Twice a day or whenever you feel the need to do so, wrap some ice cubes in a small piece of cotton cloth and place it under your itchy armpits until it melts. The coolness cleanses the skin area and increases the rate of healing. Though it won’t stop the fungal or bacterial outbreak, it can reduce the symptoms and prevent small bumps and blisters from worsening. More than that, it provides relief from the burning and itching sensation, stopping you from scratching your underarm rash and making it worse.

Hot compress meanwhile decreases the possibility of an outbreak. It protects the skin from flaking, lessens the swelling, and purifies your armpit rash from heavy sweat. Just soak a cotton cloth or towel in a bowl of tolerable warm water. Squeeze out the excess liquid and place it under your underarm rash until it cools. You can alternate the two.

Baking Soda

Baking Soda

One of the cheapest and most excellent underarm rash treatments is the baking soda. Its bleaching and anti-inflammatory qualities will help eliminate bacterial or fungal infections and reduce the swelling and discoloration. It also calms the skin relieving the itchiness and prevents it from flaking further. It might sting at first but take that as a good sign. Just mix 3 tablespoons of baking soda with water enough to create a paste. Leave it to dry over your itchy armpits for 30 minutes and rinse with cold water afterward.

Potassium Alum Stone

Potassium Alum Stone

We discussed how deodorants can irritate, depending on your skin. If you suspect it might be the case, try temporarily switching to a milder brand or use a potassium alum stone. You may take its status as a traditional remedy for granted but it actually has astringent and antiseptic properties that can hinder infection, get rid of itchy feeling and sooth your armpit rash from the burning and irritating sensation. Simply crush a small portion of alum stone into a fine powder and apply on your underarm rash after a bath. See for yourself an improvement within days of regular use.



Known for its potent anti-inflammatory quality, turmeric has many benefits as an underarm rash treatment. It can eradicate bacteria which causes armpit rash, sooth the affected skin while diminishing swelling, redness, and irritation. Like with baking soda, blend together 2 tablespoons of turmeric powder with water or lavender oil. Apply to your itchy armpits and wash away with clean water after letting it dry for at least half an hour. You may have to deal with the yellow stain it leaves but it’s going to be worth it.

Apple Cider Vinegar

Apple Cider Vinegar

Being an antiseptic agent, apple cider vinegar is an efficient solution to your underarm rash. Saturate a cotton ball with the mixture made with water or aloe vera gel and apply it on the area. Leave for 20 to 30 minutes before cleaning with water. Perform these simple steps at least once a day or more if necessary. Its acidity will kill the bacteria proliferation without damaging your skin. It also provides relief over irritation and pain.

Lemon Juice


You can use lemon juice as it is or adds it up with 1 tablespoon of turmeric. Either way, apply the squeezed juice in your armpit rash, endure the sting and do not wash away. Let it act like a natural deodorant with a fresh lemon scent. The juice is a powerful antibacterial underarm rash treatment that kills the bacterial and fungal infection.

Benefits of Aloe Vera

Aloe Vera

It’s much better if you have an aloe vera plant in your backyard. Pull out some fresh leaves and extract its gel by splitting it into pieces. Use a cotton ball to apply the gel in your itchy armpits. Let it rest for about half an hour before washing with water. This amazing plant is highly recognized for working as a natural ointment that swiftly appeases irritation, relieves the painful sensation and offer moisturization.

Coconut Oil

Tea Tree and Coconut Oil

These amazing oils are effective remedies for your underarm rash. Infuse a cotton ball with tea tree oil and apply to the affected armpit. Bathe with water after keeping it for 20 minutes. The same procedure can be performed with coconut oil. The antifungal quality of tea tree oil is effective in inhibiting the growth of bacteria and fungi while the coconut’s anti-inflammatory property gets rid of the swelling.

Olive Oil

Other Forms of Soothers

There are a lot of soothers to be used as an underarm rash treatment and this includes Olive oil which has Vitamin E for moisturization and nourishing the skin, stopping them from getting flaky and dry while preventing inflammation and redness. There is also honey which when mixed with lemon juice can be very potent in addressing armpit rash. On its own though, it’s humectants-enriched making it an effective anti-inflammatory. You can also use oatmeal, cinnamon, Indian Lilac and Shea Butter among all others.

Healthy Habits
