Why is there only a Manufacture date (MFG) on my product?Updated 7 days ago

We assign a manufacture date to products that are either new or have undergone a formula revision, but do not yet have a stability study to support an expiration date.  

The way an expiration date is determined involves several lots of a product with a manufacture date undergoing accelerated stability testing. The results are then received, and the product’s shelf life is defined. 

Until we have determined an expiration date, we recommend that a product with a manufacture date be used in the first 24 months after the manufacture date on the bottle.
