I'm thinking of stopping restylane filler and getting fat transfer to my face. How long should I wait?

I'm hesitant to do the fat transfer cause my plastic surgeon overfilled one of my cheeks but when done right I think it would look so natural. I've been getting steroid treatment for my cheek and it's slowly improved. Have you heard of beautifill for facial fat transfer and a facial plastic surgeon that has done many treatments with this device? When I find the right doctor I would like to stop the restylane filler. Need advice please.
