If you recently started using natural deodorant and then developed a rash or some other kind of skin reaction, you’re not alone. People make the switch to natural deodorants for all sorts of reasons, from concerns over specific ingredients to an appreciation for essential oils. But for a subset of people, it can also lead to some unpleasant results, like a rash, sensitivity, redness, or acne. That’s particularly true for people with sensitive skin.

That’s because despite their “clean” marketing and aesthetics, natural deodorants are just as likely to cause irritated skin as any other product.
