Why does the left side of my face look a lot worse than my right side? How can I fix this? (photos)

You are beautiful, stop obsessing, and don't waste your money.  I say this as a second generation plastic surgeon in practice for 18 years AND as the mother of 3 girls.  Jane

This is my expertise and a huge portion of my practice. Asymmetry is normal and expected. Buccal fat pad gives slimming not symmetry. Masseter botox will make you slimmer and make the jawline more loose. Fillers help give shaping and contouring. If you want perfect or close to perfect symmetry you need maxillofacial surgery or implants customized. I suggest seeing an expert to go through all options. 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 morpheus8 or PiXel8 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 Always use at home derma rolling (see link to Emerageskin x anteageMD roller plus stem cells/hyaluronic acid ampules) and peels like emeragecosmetics enlighten or aerify that can be used to improve skin quality and tighten the skin while improving wrinkles, pigmentation, acne, and Melasma. See an expert who does facial shaping with surgical and non surgical methods to get a comprehensive option. Best, Dr. Emer.

It seems to me you're a beautiful young lady and you do not need anything done at this point. If this issue is on your mind all the time and you're obsessed with normal asymmetry that everyone has, then get professional help. 

Thank you for your
question in regards to a liquid face lift. Every person has asymmetry to them. Fillers do not seem to be needed at this time. To be sure, see two
or more board-certified providers in your area for a complete evaluation to
make sure you are a good candidate and that it is safe for you to have
treatment. I hope this helps.

Thank you for your question and for sharing your pictures.  Everyone person has asymmetries between the right and left sides of their face and body.  Your photographs do not demonstrate any that require treatment at this time, and you would best be served by starting a good skin care regimen to maintain your skin indefinitely.  Check out my blog site below for useful tips.
