We put a manufacture date on a product that has had a formula revision or is a new product, but we do not yet have a completed stability study to support an expiration date. The first several lots of a product with a manufacture date is put on accelerated stability testing, and as soon as results are received the product’s shelf life is determined. Until an expiration date is determined, we recommend that a product with a manufacture date be used in the first 18 months after the manufacture date on the bottle.
