Is it normal to have severe swelling after IPL treatment? (photo)

This is an unusual presentation following IPL. Are you an allergic individual? Best to NEVER repeat the IPL. Also did the IPL head of device touch your facial skin, it may have ben contaminated ///

No, this is very much abnormal. My assumption is that you are allergic to a topical numbing cream that you used prior to treatment. This is the only time I have seen a reaction even remotely similar to this. It will resolve, but it will take time. "This answer has been solicited without seeing this patient and
