Why is there only a Manufacture date (MFG) on my product?Updated 2 months ago
We place a manufacture date on a product that is either a new product or has had a formula revision, but doesn’t yet have a stability study done to support placing an expiration date.
The way an expiration date is determined —> several lots of a product with a manufacture date are put on accelerated stability testing - results are received and the product’s shelf life is determined.
Until we have determined an expiration date, we recommend a product with a manufacture date be used in the first 24 months after the manufacture date on the bottle.
