At least from the photos, the use of robust HA fillers would ( in the hands of an experienced, board certified cosmetic dermatology physician injector) easily and quickly address all of the problems you mentioned. Jowls and marionette lines, such as these (as well as more advanced cases) are treated daily in active practices. So, let's get to the significant downsides of "more permanent" treatments. Clearly, more permanent solutions, such as expensive, invasive cosmetic surgeries-- that risk infection, scarring, and prolonged post-surgical downtimes (see all the complaints about these surgeries by members of Realself--were it not for the fact that WE are not permanent. This means that what might look nice now, in five or ten years, when we continue to age and lose fat, muscle and bone, we once again have all these cosmetic problems return (as well as others). So, that's really not permanent. Now, let's take permanent fillers, another supposedly more permanent solution. Permanent fillers, simply because they do not have any means for dissolving them away, can translate into persistent or permanent problems if there is an unwanted or undesirable cosmetic result. What's more, these problems may not start immediately after treatment; they may in fact first appear five, ten or even twenty+ years later. On the other hand, the use of robust HA fillers can treat these issues and can be rather easily dissolved away should the need arise. And, what's more, their future use can be adjusted to address future changes age-related changes in the face. I hope this information helps and best of luck.
