Why is my face so asymmetrical? Age 18. (photo)

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.

Everyone has some degree of asymmetry to their face. Your eyebrow asymmetry is very mild, so the best option for you at this point is most likely a Botox brow lift. Botox can be precisely placed in such a manner as to elevate the brow slightly, which is all you need.  
If you’re still leaning towards surgery, a 1-mm brow lift can be performed under local anesthesia to give you a naturally alert and refreshed look.  The procedure can be performed bilaterally or unilaterally which seems to be what you’re looking for.  Local anesthesia means that you can be awake and help direct your final outcome by giving feedback on the look we are going for.  
Your first step is to find a board-certified facial plastic surgeon who can evaluate your brow droop and recommend the best corrective measure.
I hope this helps!

Thank you for your question. You are young and your face will continue to mature over the next few years. It is important that you know that nobody has a perfectly symmetrical face. In fact, an asymmetrical face is natural and perfect symmetry cannot be achieved even through surgery. It would not hurt for you to consult with a board certified facial plastic surgeon to answer all questions you may have. It is always important to be informed.
Best wishes,
