21 yrs old my nose is wide when I smile and my nostrils are asymmetrical. I want them to be symmetrical. Options?

Your concerns are very common. The nose can be improved by adding refinement and definition to the tip. Keep in mind that your desired nasal shape is helpful in order to communicate with the surgeon your desires, but surgery must be performed within a patient's anatomical limitations. We must also aim to keep the nose in harmony with the rest of the facial structure. The best way to proceed would be an in-person consultation with a rhinoplasty specialist to review your concerns in detail and discuss the types of changes you would like to see.
Be sure to see an expert who specializes in rhinoplasty and facial aesthetic procedures.
All the best,

hello thank you for your question and provided information as well..based on the photos shown, to get the type of nose that is in the example photos as a base you must have another type of nose more elongated and with curvature in the dorsal part of the bone.but in your case the ideal is to consult in person by a certified plastic surgeon to see your case and evaluate which technique would be ideal in your case.

Hello and thank you for your question. Based on your
photograph, you may benefit from a tip refining rhinoplasty. Your surgeon can
accomplish this by trimming, suturing, and reshaping the cartilage in your
lower nose.  Make
sure you specifically look at before and after pictures of real patients
who have had this surgery performed by your surgeon and not just a computer
animation system. The most important aspect is to find a
surgeon you are comfortable with. I recommend that you seek consultation with a
qualified board-certified plastic surgeon who can evaluate you in person.
Best wishes and good luck.
