What to do in case of Deodorant Allergy

A deodorant allergy is an inflammatory reaction of the underarm skin, which can cause symptoms such as intense itching, blisters, red patches, redness or burning sensation.

Although some fabrics, especially synthetics such as lycra, polyester or nylon, can also cause underarm allergy, in most cases this irritation arises due to the deodorant used. This allergy happens because some deodorants may contain more irritating substances, such as perfumes, which can make the body develop an inflammatory response. See other causes for skin allergy.

Therefore, when the first symptoms of allergy appears, it is recommended you wash your underarms with abundant water and  neutral pH soap, to avoid aggravating the reaction, passing then a little soothing cream, with aloe vera, for example, to hydrate and soothe the skin.

The diagnosis of an allergy to a deodorant can be done by a dermatologist, who will observe your symptoms and see the state of your underarms, after applying the product.
