Will fillers help give my nose a smoother more symmetrical look? (Photos)

Filler makes things bigger. The task of using fillers to make the nose look symmetrical and lump-free on the frontal view would be to fill in relative depressions, adjacent to bumps, on that frontal view. But that would just work only partially, and it would make your nose look wider, and I don't think you'd like it.
You have a wide upper bridge, where the nose is made of bone, and a wide tip, where the two tip cartilages are strong and broad. The correct goal would be to make the bumpy areas more narrow, with a rhinoplasty, rather than filling in dents with filler.
But this is not an easy operation that any rhinoplasty surgeon can accomplish. Remember that rhinoplasty is an exquisitely difficult operation to get right, and you should only have surgery if you are able to make yourself very confident in your surgeon's skills. The changes that your nose needs require advanced techniques, requiring skill that most plastic surgeons don't possess with expertise. For most noses, it's much better to not have surgery than to have inexpertly-performed surgery. Read my essay on how to stay out of trouble while selecting a rhinoplasty surgeon. And for those who have had previous surgery, it also discusses how to tell whether your first surgeon should be performing your revision.
Your nose is also a perfect example of why computer imaging is mandatory in rhinoplasty. You need to know exactly what the surgeon is planning to accomplish -- what features he thinks he can change, and by how much he thinks he can change them. I always email morphs to my online rhinoplasty consultations. When you see the surgeon's goals in the morphs, you'll know whether he has an eye for an attractive nose, and whether he shares your opinion of what constitutes an attractive nose. You'll also know whether the changes he proposes are large enough to be meaningful to you, and whether he understands your wishes enough to address all of your priorities. How would you ever get that figured out without the morphs?

Adding injectable fillers to your nose would only lead to a larger and wider nasal appearance. Based on your photos, I suspect you have an over projected nasal appearance that is also wide. Rhinoplasty surgery may be considered for achieving a smallersymmetrical, less distracting, and more feminine nasal appearance. I hope this helps. Sincerely, Dr. Joseph

I recommend getting a formal evaluation with a cosmetic dermatologist to go over your desired results. Facial fillers (like Voluma, Restylane, Juvederm) can be used to improve the symmetry of the nose, but surgery would be needed to improve nostrils or overall shape. Best to see an expert. - Dr. Emer
