Unlike most other products in your bathroom, you'll notice all of our products have an expiration date. That's because none of our products contain preservatives. Preservatives inherently prevent bacterial growth, so they are not compatible with the AOB in the Mist. 

• The Mist will keep its potency for 6 months in the fridge or 4 weeks at room temperature. 
• The Cleanser does not contain live bacteria, and is completely sterile until your first pump. Once you begin using your Cleanser, it will last for 8 weeks. 
• The Shampoo and Moisturizer do not contain live bacteria, and are completely sterile until your first pump. Once you begin using your Shampoo or Moisturizer, they will last 6 months from the first pump.
