Can you perform IPL with a Candela Gentlemax pro laser? (Photo)

I purchased an IPL treatment at a medspa and was completely burned and blistered and now scarred, a supposedly rare occurance. I've had IPL before and never had an issue, just minor redness. I looked into the device they used and it was a Candela Gentlemax pro laser, it doesn't look like any other ipl device I've seen and they didn't put gel on my face like you're supposed to. I asked them and they told me that it was IPL, but I think they are lying in order to cover themselves.
