Should I discontinue adapalene before vbeam treatment?

There is no reason to change any topical therapy before VBeam treatments.  I suggest you talk to your physician about their protocols however.  Best, Dr. Emer.

You've done your homework here!  You're right in that 3rd gen. retinoids like adapalene are thought of as less photo-sensitizing than Retin-A, etc.  That being said, I usually like people to stop all topicals a week before Vbeam treatment since this laser operates in at the top end of the range that can cause photosensitivity - and that's something that can sneak up on you.   Adapalene works slowly and holding a few days is rarely an issue for my patients.  Also, Vbeam may help decrease acne by decreasing blood flow and inflammatory mediators in your immune system.  We don't market Vbeam in this way, but consider it a happy "side effect" in some people.Of course, get your doc's opinion on the matter.  Good luck!
