"I hate this product. If you can live with your skin's current state DO NOT USE THIS. Many people experience a purge when using this, so their skin gets much worse before it gets better. This happened to me and there was no sign of improvement so I stopped using it and my skin improved greatly. The purge was not worth it at all for me because my skin was not to terrible when I started using the product, and after using epiduo made my skin worse I was left marks that still haven't faded two months after stopping epiduo. If a horrible purge is not worth it to you, do not mess with this stuff."
