Start using our aluminum-free deodorant and stop using your current anti-perspirant. When you quit using an anti-perspirant, there is a natural purging process that begins. Your pores release the aluminum that was built up from using an anti-perspirant, which may result in some odor. This phase will last around 2-4 weeks. To help speed up this process, we recommend using an exfoliant like our Bum Bum Body Scrub. And remember, you may need to reapply an aluminum-free deodorant throughout the day to keep bacteria away.
