I Am Breaking out After IPL Treatment. What Causes It and What Should I Do?

After my third IPL treatment, parts of my face have itchy red bumps all over them, they look like acne. I had this happen after the second treatment, but not as severely and I thought it was due to a new cream they used on me after the treatment. It looks horrible and itches like crazy. What is causing this and what is the best thing to do for it, last time it took about 10 days to clear up and this time it is much worse. If it helps, the areas that have hair on them are the worst.
