34 and wondering what non-invasive treatment for my extremely droopy, asymmetric face, nasal folds, jawline is best?

Dear,
fat trasfer could be a useful treatment for you, when  performed very deep. Then it reinforces the zigomatic ligament and createsa lifting effect at the medial and even upper part of your face, besides fillıng the empty areas, partially responsibles of the sad look.
This "sad look" can be due sometimes even to the shape of the eyes (that I cannot see from the pictures) so there are other treatments you may benefıt, such as botox or brown lift..
Furthermore it is possible to harvest stem cells from your fat to improve the skin texture, in partıcular in areas that cannot be filled, such as forehead and skin in general.
In your case in order to have a better and more complete result (but mainly to treat the lower third of your face), I would suggest you to have fat trasfer as a support of another treatment at the same time, which is called face suspension or mıcro-lıft.
Mıcro-lift is a kind of non-surgical liftıng where temporal sides, sides of the jaw, cheeks and neck can be treated, suıtable for patients with minor skin sagging between the ages of 30 to 35. It gives a scar free, permanent and natural results by movıng the sub-dermal tissues to their original places, and, similar to a facelift operation, suturıng them in a solid area.
It is performed ın 20 to 45 minutes without general anaesthetia but under sedation and local anaesthetics. No large incisions are made thus no scars are left and ıt ıs painless.
Hope this helps
Best wishes,

Aging is a combination of multiple issues including sun damage to the skin, volume loss, especially around the eyes, surface problems, and lifting for sagging.  I believe that each problem requires a separate method to achieve the results but there is some overlap.For example, for volume loss both fat transfer and fillers work well.  I typically use fillers for someone under 40 years of age for two reasons.  First, they don't need that much volume and, second, if the person should gain a lot of weight with aging they can look too full with fat over time.  However, I have definitely seen people with enough volume loss to justify fat in your age group and who understand the risks long term of maintaining their weight within 10 to 15 pounds (depending on one's height and weight).  Fat has the advantage of providing durable results that look natural in the right hands but there is a small percentage of absorption.  The problem with fat in my opinion is that it is harder to manage like smile lines or surface skin problems.  Even in my fat transferred patients, I still use fillers to touch up the results and to maintain them.  Of course, the natural question for most is that they want to have a long-term solution.  Interestingly, I have found that fillers truly do hold but after they have been done repeatedly over a year or more.  Like anything nothing stops aging but the durability is unquestionable in my opinion.For the early jowl and sagging of the jawline and lower cheek, a facelift is really the best method to improve this area.  However, most 30 somethings simply cannot fathom undergoing this procedure so early, so I usually encourage them to do fillers until the situation gets worse.  Those are very motivated I tell them that nothing improves the jawline, neck and lower cheek like a facelift.  The facelift that I perform is a deep plane facelift so the results truly hold long term.  For the skin surface problems, the best solution is laser.  I use the Sciton laser for this problem.  In general, I would have to see you to determine your candidacy but just by the photos, this does not seem to be a major issue.In short, I would probably go the filler route for you to improve little things that are problematic and I think you should be very happy.  However, for the very motivated patient who can financially and recovery wise (up to 2 weeks) handle it, then a fat transfer with a lift or just fat transfer (plus some fillers down the line) could be a reasonable alternative.
