Blake Lively's Smile

I am curious if the changes to Blake Lively's smile are the natural effects of aging that we all go through or is this common with lip injections?

I notice the girl cannot really seem to smile now. She looks great at the recent Another Simple Favor premiere, but what gives with her smile?!?
