Are there any risks in getting Rejuran, botox or fillers when on Accutane?

The short answer is, it's ok. It's ok to have botox, fillers when you are on Accutane. But you might want to avoid certain things like laser treatment on the skin, fractional lasers, skin lasers, essentially I would avoid or rather you should stop for a bit before getting laser treatment done. But for injectables, they are generally safe, unless your skin is really sensitive, at that point then maybe you may want to wait a bit before getting any of these.
