I had a a photo Facial/IPL and the tip was cool but she didn't put a gel on my face first. Is that normal?

Every time I've done or seen an IPL machine used it had ultrasound gel used with it. That being said there are literally hundreds of brands of machines on the market so I have no idea the specifics on all machines. "This answer has been solicited without seeing this patient and cannot be held as true medical advice, but only opinion.
