In general, rashes are a major inconvenience. However, rashes in more delicate areas can be a bit embarrassing, especially since many people associate the condition with poor hygiene. One such area is your underarms.

You should wipe that notion of poor hygiene from your mind, though. According to some Kent urgent care doctors, most cases of underarm rashes are a form of contact dermatitis, an allergic reaction that occurs when the skin comes in contact with a particular chemical. In the case of your underarm rash, the likely culprit is your anti-perspirant deodorant.

Anti-perspirant deodorants contain a mix of chemicals that regulate the conditions of your underarms. Although effective in eliminating sweat and body odor, some of these chemicals can be too harsh for sensitive skin; thus, the rashes.

In most cases, contact dermatitis-related rashes appear within 24 hours after exposure to an allergen. If you develop a rash in your underarms, Katie Lambert and Jason Nell of How Stuff Works suggest you enter a process of trial and error:

If you suspect that skin care products or household chemicals are causing your rash, the best way to avoid contact dermatitis is to identify the offending product and discontinue its use…

Determining the culprit may require some trial and error, but it’s best to start with your deodorant. Other items that may cause underarm rash include laundry detergent, soap, shampoo and lotions.

Of course, it is easy to pinpoint the cause of the rash if you’ve recently used a new product. If the rash appears suddenly, however, even if you haven’t changed your routine or products, your preferred brand may have altered the ingredients in the product. Keep that info tidbit in mind since manufacturers are not legally required to announce any changes they make to the ingredient list of their products.

If you still cannot determine the cause of your rashes, do not hesitate to visit a center offering occupational medicine and urgent care in Kent, WA, like U.S. HealthWorks Medical Group. Through a comprehensive interview, an experienced doctor can help you determine the cause of your underarm rash. Afterward, your doctor can prescribe an effective rash cream to help relieve the itch and redness in your underarms.
