"i hate this product. if you can live with your skin&#039;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&#039;t faded two months after stopping epiduo. if a horrible purge is not worth it to you, do not mess with this stuff."
