How to get rid of armpit rash

Updated February 21, 2017

The underarm area is a very sensitive zone on the body, and unfortunately, it is also very prone to rash. As one of the warmest places on the external area of the body, it is a breeding ground for bacteria, and rashes can easily develop as a result of a reaction to chemicals, environmental elements or even personal body conditions. However, rashes are easily treatable, and with some preventive measures and basic care, you can get rid of rashes under your arms.

Find out what is causing your rash. This can best be identified by when the rash occurs. For instance, if it appears after you shave, you may be experiencing razor burn. However, if the rash appears infrequently, you may have dry skin or a reaction to excess perspiration. Persistent rashes under the arms can also be caused by an adverse reaction to chemicals in washing powder or deodorant.

Treat the symptoms with natural remedies. Although there are plenty of lotions and creams out there, the underarm area is a very sensitive zone, and the chemicals in these products can actually exacerbate the rash. Instead, try using products such as tea tree oil, aloe vera and vitamin E-enriched lotions (without dyes or perfumes) to help heal the rash and promote healthy skin growth.

Keep the affected area as clean as possible and wear clothing that hangs loosely around your underarms. If possible, avoid prolonged exposure to heat or intense activity, as this can cause excess perspiration, which can further aggravate a pre-existing rash.

Change your habits to combat future instances. If you believe your rash was caused by your deodorant, try switching brands or using a more natural product with fewer chemicals. If you believe that the rash was caused by shaving, try alternative methods of hair removal, or try using lotion. If you believe the rash was caused by dry skin or excess perspiration, consider seeing a dermatologist for treatment options.


If the rash spreads quickly or you experience moderate or extreme pain, your rash may be a sign of a serious infection, and you should see a doctor as soon as possible.
