Cheek filler migration? Smile lines? (photos)

I have a question regarding my cheek/smile line area. I have a problem area (please see circled area) and I’m not sure if this is due to old migrated filler or loss of laxity so I’m unsure how to move forward with which treatment will be best…filler dissolve, pdo threads..etc Please note- I have had cheek and smile line filler in the past (1-2 years ago)
