How can I fix my asymmetrical face? Would you suggest a small amount of Botox? What is the best solution for this? (photo)

We often tend to be our own worst critics. I think you have some beautiful facial features. Remember, almost every person has some facial asymmetry. I think you could benefit from filler treatment to the chin and prejowl area which would improve lower face proportions and symmetry. I would also consider a neuromodulator like Botox or Dysport to improve eyebrow symmetry. I think it's important that you first schedule a consultation with an experienced aesthetic physician who will evaluate your face in detail and come up with an appropriate treatment plan to address your specific concerns. 

Dear Lexihall,
Thank you for your question. To be very honest, you have a beautiful face. Beauy lies in having asymmetry. Every face has slight asymmetry between the left and right side. That's why the mirror image of your left and right side is never the same.It's what makes us unique. 
You option includes accepting your pretty face vs adding a bit of hyaluronic acid filler to 1 side. I would go with the former.
I hope this helps.
