I stopped Doxycycline for 3 days and going to have IPL laser. I got rashes, mild blisters on my face. What should I do?

Your physician needs to determine if the blister is herpetic or from thermal changes due to the IPL. Herpetic lesions need to receive oral antiviral. Blisters can be treated with semi occlusive dressings or antibiotic ointment. Good luck.Jeff Rapaport MD FAADRealself All-star

It's important to followup with your physician to determine if this is related to a thermal injury from the IPL itself or is some sort of infection (viral in many cases).
