What can cause a rash under the armpit?

You may realize that sometimes the deodorant can affect your skin causing some red, itchy and pimple like rashes. Deodorants make the skin sticky which leads to increased friction in the skin folds of the armpit.

Moreover, the elements or the ingredients used in the manufacture of old spice deodorants may cause skin rashes. The reason being components of the deodorants may be allergic causing reaction against your skin. Rashes in the armpits, (which are as a result of deodorants) are itchy, bumpy and red.

Contact dermatitis.

Contact dermatitis, also known as eczema, refers to a situation which occurs when the chemicals you come into contact with lead to a reaction against your skin leading to tissue inflammation. Most of these reactions are mild and they cause itching which goes away after some time.
