How To Get Rid Of A Rash Under Breasts

A rash under the breasts is a very common problem. It is mostly a form of irritant dermatitis and is called intertrigo characterized by inflammation of skin folds.

The most common causes of breast rashes are excessive sweating, heat, lack of air circulation, and wearing an ill-fitting bra that rubs against the breasts. Thus, factors like hot, humid climate and obesity contribute to this problem.

The condition may also be accompanied by yeast or other types of fungal infections as the warm, moist environment harbors the growth of germs.

Sometimes it can even be due to some kind of allergic reaction or an infection of the breast tissue due to breast-feeding. It can cause red patches, a burning sensation, itchiness, dryness and great discomfort.

You can try some simple natural remedies to get relief from this problem. Also, consult your doctor, especially if there are signs of infection.

Here are the top 10 ways to get rid of a rash under your breasts.

1. Cold Compress

A cold compress can relieve many of the symptoms like itching and burning sensation caused by rashes under the breasts.

  • Wrap some ice in a thin cotton towel and put it over the affected area for five to 10 minutes. Take a break and then repeat.
  • Another option is to apply a skim-milk and cold-water compress using equal parts of both the ingredients to relieve itching and reduce swelling.
  • Also, try bathing with cold water. It will help close the skin pores, thus reducing sweating and the appearance of the rash.

2. Cotton

The best way to deal with a breast rash is to reduce the accumulation of sweat around the breast area.

  • Place a thin piece of cotton between the lower part of your breasts and the skin underneath to absorb moisture and create a barrier. You can also use soft paper towels or dinner napkins.
  • Also, wear lightweight clothing, preferably made of cotton or natural fibers that help absorb moisture and keep your body sweat free.

3. Vinegar

At times, the chemical residue present on your clothes can cause a breast rash. Vinegar can help solve this problem.

  • Mix one-half cup of white vinegar in half a bucket of hot water. Use it to wash all your bras and dry them in direct sunlight.
  • Another option is to apply apple cider vinegar on the irritated skin. Wash the infected area with mild soapy water, rinse with cold water and pat dry. Mix one teaspoon of apple cider vinegar in a cup of water and apply it to the affected area. Do this two or three times daily. If it causes discomfort, stop using it.

4. Cornstarch

Cornstarch is highly effective for alleviating the itching and burning sensations associated with a breast rash. It helps keep the skin dry. In case of a fungal rash though, simply use talc as fungi feed on cornstarch.

  1. Clean the affected skin with soap and water, and then pat dry with a towel.
  2. When the area is completely dry, lightly dust cornstarch over it.
  3. Do this at least twice daily until you completely get rid of the problem.

Note: Do not apply cornstarch on moist or wet skin as it will increase the risk of fungal infection.

5. Coconut Oil

Coconut oil has a soothing and healing effect on skin that helps provide relief from rashes. Plus, due to its greasy nature, it will help reduce friction that causes rashes under breasts and also avoid infections, thanks to its antibacterial and antifungal properties.

Simply apply some extra-virgin coconut oil on the affected area and allow it to absorb completely into the skin. Do this two or three times daily until the rash is gone.

6. Calamine Lotion

Calamine lotion can be used on a breast rash to provide soothing relief from itching and speed up the healing process. It will also helps keep the area dry and thus reduce the chance of infection.

  1. Clean the affected skin with a mild soap and lukewarm water. Pat dry the area with a towel.
  2. Use a cotton ball to gently apply the calamine lotion.
  3. Repeat several times a day.

7. Tea Tree Oil

Tea tree oil has antifungal properties and hence it can be used topically to treat a breast rash. It will also prevent the growth of fungus and infection.

  1. Mix six drops of pure tea tree oil in four tablespoons of olive oil.
  2. Dip a cotton ball in this oil and apply it on the rash.
  3. Massage the area gently so that the oil penetrates deep into the skin.
  4. Do this right after taking a shower and again before going to bed. Usually you can notice positive results within a few days.

Note: Using tea tree oil straight on your skin without diluting may cause skin irritation.

8. Aloe Vera

Aloe vera helps soothe the itching and burning sensation caused by rashes under breasts. It also helps heal the skin and has antibacterial and antifungal properties. You can also combine it with turmeric as it has antiseptic properties.

  • Extract fresh aloe vera gel from an aloe leaf and apply it on the affected area. Leave it on for at least 20 minutes. You need not wash it off.
  • You can also use aloe vera gel mixed with a little turmeric powder. Leave it on for 20 to 30 minutes before washing it off.

Use aloe vera a few times daily on your skin until the rashes heal completely.

9. Garlic

A rash under the breast area can be easily treated with the antiseptic and antifungal properties present in garlic.

  • Soak a few garlic cloves in one-half cup of olive oil overnight. The next day, apply this oil on the affected area and leave it on for a few hours before washing it off. Use this remedy three or four times a day to get rid of the problem. Instead of this oil, you can also use crushed or pureed garlic cloves.
  • Also, increase your intake of garlic in raw or cooked form to speed up the healing process.

10. Lemon

Lemon juice contains vitamin C, which is a powerful antioxidant and helps prevent the growth of fungal infections and speed up the healing process.

  • Dilute one tablespoon of fresh lemon juice with three tablespoons of water. Apply it on the affected skin and allow it to air dry.
  • You can use a mixture of two tablespoons of lemon juice and a little raw honey on the rashes. Leave it on for 15 to 20 minutes and then rinse it off.

Repeat either of these remedies twice daily for a few days.

Additional Tips

  • As this problem is common in those who are overweight or obese, it is suggested to lose excess weight.
  • To reduce friction that causes the rashes under breasts, apply greasy topical ointments.
  • Wear clean, dry bras made of breathable fabrics like cotton. Avoid improperly fitting bras and bras made from synthetic fabric.
  • Wear light clothing, minimize moisture, remain in a cool environment, and avoid irritants.
  • Launder your undergarments carefully.
  • Check if you are allergic to the cosmetic and hygiene products that you are using.

  • 2am and cannot sleep again. Trying Coconut oil under breasts tonight - so far still a bit itchy, the inflammation has settled a bit. I have had mild success with Epsom salt baths, apple cider vinegar, baking soda and tea tree oil, aloe vera, Dr Scholls foot spray and airing in sunshine (pleasant but not practical). Creams recommended by doc have not worked. But Prickly Heat Powder has been very successful but a bit messy for work days and needs reapplying. This powder is an Australian product containing zinc. I have been on a diet for a month now and hope losing weight will help with the excessive sweating. Goodluck everyone

  • I too have had an operation, am immobile for weeks and this problem is driving me nuts. I am unable to use the bath and showering takes hours so have to hand wash. I have it under all the folds, breasts, tummy tuck and groan, and have had it on and off for years but usually can sort trying various methods. This time it is driving me mad and nothing seems to work. I feel as if I am really dirty and doctors have no sympathy. I haven't tried vinegar and nappy rash cream so will give that a try. Can't get some of the stuff here in uk. Thanks for all the help. Just great to know you aren't alone at 3 am when you can't sleep.

    • Hi Susan - I appreciated your situation as I often feel "dirty," too, and have recurring rashes under my large ladies, under tummy roll, and inner thighs. Constantly changing and laundering panties. Have been home 3 mons. from hospital and housebound yet, even with a/c, here in Escondido, CA it's been like a desert so we're always suffering from the heat; even swimming aggravates if I wait too long to use hair dryer under breasts and other areas. WHAT HELPS is, after cleansing areas with Tucks (witch hazel) pads, apply a generous amount of Zeasorb athlete's foot powder (thoroughly wash hands afterwards) - this procedure provides almost immediately relief! Other hints that help: Use hair dryer in affected areas after bathing or swimming/jacuzzi, wear folded kleenex tissues (cheap) in bras or just tucked in under breasts. I have really appreciated and enjoyed everyone's sharing their experiences as now I don't feel like the lone ranger and realize this situation is a common one. Best wishes to you all!

  • Right after exercising one day, I found the worst, reddest rash under one single breast than I had ever seen in a rash ever before! And I'm 49! I couldn't afford to buy tea tree oil, but I had coconut oil on hand, so I tried it. Man, did it work! Now, understand that some days I also did something a little different: I wore a thin, cotton undershirt, then a cotton bra, followed by whatever shirt I was wearing that day. This helped soak up any extra perspiration. It's been close to a week, and it has really improved. And I have one of those stubborn bodies that don't like to heal well! So if you have any, try it. If you think you're about to get a rash, put a thin amount on, and do preventative measures, as well.
    STAY AWAY FROM EXCESS ANTIPERSPIRANT. Sadly, it's a known breast cancer.

  • The itching went away with Tea Tree Oil & alcohol mixed in a small spray bottle. It burned at first but relief afterwards.

  • Tried the coconut oil it feels like pouring salt on it hurts worse screamed and cried while washing the oil off of my skin and after drowned the area in a mountain of baby powder with aloe vera extract and finally topped it with a baby powder covered cloth for the night

  • I'm a mess,been having out breaks of candida fungal under big boobs going on 4 years,tried all prescription meds,athletes foot stuff,zinc oxide,Monistat,vinegar baths,going crazy it hurts,oozes,gonna try a ta ta bra next

  • I used aloe vera once when I burned my hand pretty bad and it imeaditly stopped the pain. but i have a question. I have anxioty and i hate taking medicine to the point where I won';t take something if I possible get by with out. They say I am diabetic and wants me to take metformin. well I now eat flax seed in the morning with cereal. and cut down on pop sweets. I have lost 6 pounds and my blood sugar is in a good range. it wasn't that high to begin with /// ok I have had before and have again an infection under the skin near my nipple and they gave me zpack cause I have taken it before. but now I am afraid to take it. what can I put on it to draw out infection with out antibotics. thank you .

  • Great site! I have Hashimoto's Thyroiditis, and it has greatly affected my skin. Yeast under the breasts has been a problem now annually, even without any blood sugar issues. One thing I would like to share, just in case anyone else has this sensitivity - if you emollients that contain Lanolin, such as Aquaphor, Eucerin, or A & D ointments among others, try a small patch on your arm, etc. first. I learned (the hard way!) that Lanolin is a very common allergy (it's a wool alcohol so if you are allergic to wool that's a good indication you are sensitive) and it's in quite a few great products for skin. If you are sensitive, though, it's a nightmare! I put a Lanolin based product I used happily on my hands for years under my breasts and they flared up horribly. Wonderful if you are not sensitive, Lanolin, Bacitracin and some other great products are deal-breakers for rashes if you are like me and are allergic to them. Hope that helps a few people. My doc, whose a saint, prescribed it for me before we knew I was so sensitive. I check the inert ingredient or 'other ingredient' lists now on any topicals.

    Thank you all for the great advice you have shared! With my sensitivities to commercial products I'm always looking for alternatives, especially natural ones. This forum has been a great help. From time to time I have to reach for the diflucan, but I love to avoid systemic meds whenever I can.

  • This is really good information, but I've had trouble with lotions and ointments in the past. Everything seems to make my rash worse in time - probably because of perspiration. Someone suggested getting a breast sling because it keeps the skin so dry. I'm going to try that next.

  • For those who are looking for a source for cotton bras, try Fruit of the Loom. I have several. Insufficient support for my large breasts, but if I'm not going anywhere and not dressing up, who cares? They also have front closures cotton bras. THEY RUN SMALL.
    My favorite dressing for yeast rash under my breasts and tummy roll is a salve of coconut oil and tea tree oil. You have to do it every day, though. I also use a tea tree bath soap. Every once in awhile I have to ask for a prescription of oral medication to knock down a rash in the summer. I'm 76, and this has been a problem only the last three years or so.
