5- Apple Cider Vinegar to Remove Underarm Rash

Also called as Cider Vinegar or ACV for short, is a remarkable remedy to get rid of the itching and swelling from rashes. Due to the acids it contains, ACV is a natural bacterial cleaner that clears your skin irritation and inflammation. It also provides protection for the skin problems from getting worse.

6- Use Aloe Vera on Rashes

Another great remedy for treating your underarm rashes is Aloe Vera. It also kills the bacteria and germs that cause and spread the inflammation. It opens up the clogged pores to ensure the continuity of natural processes of the skin.


Steps to Follow:

  • Extract the gel out of a fresh Aloe Vera leaf, or use its creams, lotions, ointments instead.
  • Use a cotton ball and apply it on your rash under the armpit.
  • Let it stay for about 20 minutes and then rinse it off with cold water.
  • Repeat this Aloe Vera remedy for 2 or 3 times a day.

7- Try Ice to remove the Itchiness

Applying ice can remove the itchiness and burning associated with the rashes and even may remove your rashes completely.



  • Place a piece if ice or ice cube on your underarm rashes.
  • Hold it there for few minutes.
  • Do this often whenever required.

Note: I recommend the use of ice on your skin after enwrapping it in a clean washcloth or an icepack if possible—Because with the directly use of ice comes great chances of frostbite.

How to Prevent Rashes Underarms?

Why waste money and your energy on finding and trying various treatment methods to heal your rash under armpit, if you can simply avoid getting it by taking a little care in what you are already doing, or make small changes to your daily doings;

  • Avoid scratching your rash.
  • Keep your rashes prone areas of the body clean and please don’t ever leave it damp after showering, try to use a hair dryer or if you can’t or don’t have one, then use a clean towel for this purpose— and YES shower everyday OK?
  • Your rashes may be a result of your allergy to some skin products, so if you suspect a rash is produced by the use of XYZ skin product, then simply don’t use that product in future, or consider visiting a dermatologist for further and in-depth assistance.
  • Avoid wearing tight clothing if you often get rashes because tight clothes don’t allow your sweat to pass. Make sure you take a shower after every activity that causes more sweat.
  • There are good chances that your underarm rash may be a heat rash due to hot and humid weather/climate. You can stop the occurring of heat rashes by the use of talcum powder in your armpits.
    One other suggestion is to try to stay in cool places if the weather is hot and you are more likely to get rashes in the hot weather. Also, keep your sleeping area cool with an Air Condition or a Fan.

Wrapping Up

I must tell that the cause of getting rash under armpit or anywhere on the body is not same for EVERYONE—The same way each remedy will not work for everybody. So it’s a game of Hit and Trial. Use a remedy for few days and if you see good results then stick to it, but if you got unlucky (in this case)! Then don’t lose hope and try another one from the list.

But if any of the remedy is not showing good results even after trying for 1 to 2 weeks, then you should consult a dermatologist at earliest.
