Recently Started IPL for Treatment of Rosacea Redness and Doctor Said to Stop Using Metrogel 1%, is This the Right Thing to Do?

The doctor recomended 5 treatments spaced 3-4wks apart; I have had 2 and will start the 3rd soon. He told me to stop using Metrogel while IPL is curently ongoing so it won't interfere with treatmnt results. I've stopped using Metrogel 1%, however I think I should still use it in conjunction with the IPL so results will be & look better once treatments have ended. Which option(s) would be best & who is correct-the doctor or myself? Also, why does my face re-flare one week after a treatmt?
