Men with sensitive skin may have allergic reactions to Aluminum leading to irritation. Aluminum also blocks perspiration, hence preventing the expulsion of toxins. Alcohol can cause cumulative irritation and inflammation for those with sensitive skin, and can also make the natural skin barrier more penetrable and susceptible to irritation. This deodorant is made with a sensitive skin formula that is alcohol and Aluminium free. The earthy citrus-herbal musk blend contains natural botanicals like Comfrey Root, Yarrow and Acai extracts, along with Tea Tree Oil and Chamomile.
