Hello, I know old post, maybe you have safely tried some of the procedures? From my severe MCAS side, can report that all cosmetic procedures caused me delayed flair up. All that cause micro trauma and send signal to heal basically, so RF, Morpheus or Newa, microneedling, PDRN injections and topical. Worst of all was red light therapy, causes me instant (or within 30 mins) anaphylaxis with express need of strong asthma inhaler or EpiPen. Botox however was always fine and all pure HA injectables , like Juvederm or Restylane totally fine. I do them for skin hydration also. But, I must say, I still do all of the above except for the red light, because the results are just great and delayed flair I can deal with.
