My biggest complaint: sagging jowls and marionette lines. Should I get HALO or BBL? (photos)

I am a 52 year old female, weigh 130 lbs, 5'5" in good physical health and overall have good, healthy skin. I've had a series of 3 BBLs (2021 and 2023) with good results. Should I stick with BBL? or HALO? My biggest complaint: sagging jowls and marionette lines. Would like the best procedure to generate collagen. Skin texture is pretty good. Also, is there any value in doing both BBL and HALO? If not, which one do you recommend?
