Do You Use a Dipillatory Before a Juvederm Injection or After? Will It Affect Anything?

I do not use a depilatory as a part of my lip enhancement procedure with Juvederm or any other injectable HA. I would wait one week following the injection procedure, at which time a depilatory cream, waxing, or laser hair removal treatment could be safely performed.

I would recommend using the depilatory a few days after the Juvederm.  If there is any reaction to the depilatory, like a contact dermatitis, the Juvederm session would have to be postponed as fillers really should not be injected through an area of rash.

I see no reason to remove hair on the lip unless you have a full moustach. This an issue of sterility and I have never had a problem.
