Is Being Told Not to Smile for the First Day After Restylan Injections and Swelling Normal?

I am not sure what the logical basis is for restriction of facial activity after fillers. There is no scientific data to back up this post-treatment instruction and this is not advocated in my practice.

Not smiling after fillers is a hard thing to ask of people and I don't do it. That said, it probably wouldn't be the best idea to go to a comedy club the night that you were injected as there may be very slight displacement of the filler. ~ Dr. Benjamin Barankin, Toronto Dermatology Centre.
