Unhappy with my face shape but I’m not sure what to do. Where do I start? (photos)

Relax. Your issues are very easy to address by an experienced aesthetic physician injector. A bolus of a lifting filler, such as Restylane Lyft over the cheekbone region would NOT widen your face, but instead would create the more ideal feminine heart-shaped face in front face view. In profile, a bolus of Restylane Lyft at the base of the nose as well as at the tip would help to create a more upturned appearing nose and another small bolus at the bridge would straighten the nose in profile. And finally, despite your hesitation on this, a volumizing filler, such as Voluma XC, placed in the chin would help to better balance in side view nasal and chin projection. If you wished, all of the above can be accomplished in one treatment session of about 20-30 minutes, usually cause little to no significant downtime, and the results typically engender an immediate "Wow!" reaction. Just make sure that the doc you consult with is an experienced, board certified aesthetic physician. Best of luck.

do facetite, threads, and morpheus
fillers for contouring of the face.
if you want a significant change you will need maxillofacial surgery but that has downtime.

most of my younger clients use fillers to give them shaping especially on the cheeks, jawline, and chin which make the face look more slim and tight; and threads such as PDO or Instalift can build collagen and support the facial shaping and skin looseness over time, slowing down the aging process and given the face a more “snatched” look; and morpheus deep microneedling RF can tighten crepe skin especially on the neck and jawline and is great for long term tightening of the full face, neck and chest; its often used to give the face a slimmer more sculpted look because it tightens the skin and gives lift.  an early face lift can be performed as well even in younger clients if they want a different facial shape, maxillofacial surgery with bone breaking or shaving can also be done.

For facial slimming a combination of treatments are always needed.  Options include:
1. Buccal fat pad removal to reduce fat on the lower face
2. Factite or Renuvion/J Plasma to tighten the lower face, jawline, and chin to reduce fat and give the jawline and neck tightening and shaping.
3. Botox to the masseter to reduce the muscular size of the jaw giving the face an illusion of being more slender
4. Fillers to the jawline, chin, cheeks, temples and brow help to shape the face and make it more angled and defined
