The FDA requires that any product containing an active ingredient enter into and pass FDA required stability testing and batch assays. In our case, this means benzoyl peroxide.

Stability testing involves using an independent testing facility to place the product in an incubator that is both hot and humid for several months in order to simulate two years of normal shelf life. This procedure is quite expensive but is necessary to assure consistent product effectiveness over time. I submitted Acne.org Treatment to such a test and the formula passed.

Each time our manufacturer makes a new batch of Acne.org Treatment they also send several samples of the batch to an independent lab who assays the sample. This means that the lab checks to make sure that the percentage of active ingredient in the product is in the same as the amount stated on the label. We are extraordinarily conscientious so every batch has passed this assay easily, but we will nonetheless continue to present samples to an independent assayer each and every time to be certain.
