How Soon Can I Get Lip Filler After a Bull Horn Lip Lift Aka Upper Lip Lift?

Hello there, It's almost one month since I got an upper lift along with rhinoplasty. I am wondering how soon can I get a little bit of Juvederm on upper and lower lips? Should the top be avoided at all costs? I'm wondering if the filler can make it heavy, causing it to droop. Yes or no? I just want a little bit to make them look younger. Thanks
