We've worked hard to create a deodorant that is suitable for everyone, however, our bodies are so unique and therefore some people may experience irritation, even when you previously have no history of sensitive skin. There are several causes of this including an allergy to an ingredient. The most likely cause is due to the pH difference between your sweat (acidic) and the bicarbonate of soda (alkaline). People with more acidic sweat may be more susceptible to irritation. It sounds strange but putting some diluted apple cider vinegar on the rash will help solve the pH imbalance.
If you are experiencing any painful irritation please stop using the deodorant and contact us via our contact form.
