Micro facelift, filler or PDO thread - which procedure would minimize signs of aging and be best for me? (photos)

Hi thanks for the interesting question and the photos.
This is a great question. My Personal feeling is that fillers and facelift whether it be called micro, mini or anything else are good at addressing two different things. Fillers are good at replacing volume which we do lose as we age whereas all facelift techniques address structural laxity in the face. So as we age our tissue become more lax and then with gravity migrate south leading to some of the changes you describe like jowls marionette lines and neck laxity. When we use fillers to camouflage changes in laxity this is when things start to look unnatural and overfilled in my opinion.
It is unlikely that when you are young that you would develop structural laxity but this is the key for me rather than a specific age . If you have structural laxity whether you are 34 or 54 then a facelift may be able to address this effectively to give a natural looking result. Looking at your photos I dont think adding volume with fillers is the answer but you do have some structural laxity. You mention round face as an issue and buccal fat reduction may be an option to slim the face but I would discourage you from doing this at a young age as we tend to lose fat from our face as we age and so surgically removing it when young doesn't make sense for most people.
Thread lifts are not very effective long term and also make facelifting more challenging too as you find threads in the face and often in locations you wouldnt expect or at depths which you wouldnt accept.
The terms micro , mini etc when it comes to faclift are also a little meaningless as it means different things to different surgeons so I would have a long conversation with the surgeon of your choice

Despite your age, You have descent of your midface with jowling. Mini- or micro- face lifts are an old concept that hasn't stood the test of time. Any facelift expert will tell you that the younger you are, the more important proper separation of layers before pulling on is to getting a lasting result. Mini facelifts yield mini-results for a minimum amount of time, as in one year at the most. Same for threads of any material; threads are garbage that's enjoyed social media misrepresentation.
