I have a question regarding skin procedures. Among lasers, flushing

Hello, I have a question regarding a skin treatment. I don't remember what kind of laser treatment I received in the past. I used to have quite severe redness and flushing, so the dermatologist I was seeing at the time recommended a laser treatment. All I remember is that a very cold breeze(?) came out of the laser when it was aimed at the flushed areas, so I can't find it even when I search online. The results were quite good, so I only received it once. Does anyone happen to know what kind of laser this is?
