Do the deodorant creams have an expiration date?

Yes, our deodorant creams have a shelf life of 18 months. We completely forgo synthetic preservatives. To improve the shelf life of our deodorants, we use Vitamin E. Our natural products don't follow a calendar and don't expire on a specific date. Take off the lid, smell it, and look at it closely. With our products, it quickly becomes clear when they are no longer usable.
