Next step after cheek fat transfer: threads? When? (Photo)

I am 40. I had facial fat transfer to my cheeks 2 months and a half ago. My sunken cheeks improved but there is some skin laxity (around nose and mouth). Previous attempts at using hyaluronic acid were not successful. Which could be the solutions for those skin folds? Could they improve on their own? What about threads? If they are indicated, how long should I wait before inserting them? If threads are not a solution, how could I improve this issue? Thanks and best regards
