How much time should I leave between tear trough filler and fibroblast around eyes?

I am having tear trough filler for the first time in a couple of weeks and I am also looking to have fibroblast around my eyes (eyelids and under eye for wrinkles). How much time do I need to leave it in-between the two treatments? Is there one that's better to have first? e.g. should I have fibroblast before the tear through filler or after? Thank you!!
