Did I just ruin my Vbeam Session? And is it safe to go for another session in a week?

Isn't the office doing your VBeam the same one prescribing your acne meds? It certainly should be as these need to be monitored together! First, stop using the product as it sounds way too aggressive for you. And second, give it a few days and see how your skin calms down. I'd suggest calling the office that does your VBeam to discuss it with them. Sometimes we treat people with red, bright skin as one of the things VBeam does well is treat rosacea, but if that's NOT what they are treating you for initially then this may not be the right time to do your next treatment and you may need to push it out a bit til your skin calms down. "This answer has been solicited without seeing this patient and cannot be held as true medical advice, but only opinion.
