IPL swelling after treatment - is this normal? (photos)

This is a stronger response than usual, but it can happen and will settle down, rest assured. That said, your dermatologist can provide you prescription strength antihistamines and cortisone or other topical therapies to help this subside much faster. There may even be some bruising there. At higher settings, there is a higher chance for down time / "side effects", but the results in the end are often worth it.

While you can have some swelling after IPL what you are experiencing is a bit more dramatic than I like to see. You can try an OTC antihistamine like Benadryl. You can also apply hydrocortisone to the reddened areas. But I would also suggest you call your treating office so they can note what happened and adjust any future treatments.
