My nose looks bigger in flash light and my nose changes its shape in different lights. Will bone reduction help?

Nasal aesthetics can be improved using either fillers or surgery depending on desired results. A liquid nose job, typically comprising of a hyaluronic acid based filler can correct nasal symmetry while adding volume to the bridge and nasal-tip. This procedure is non-invasive, temporary, has no downtime and can be reversed using hyaluronidase. However, fillers cannot reduce the size of one's nose.
Rhinoplasty or surgical nose correction can aid in achieving the nose of your dreams. Different techniques can be combined to achieve optimal results and can provide facial harmony. However, this procedure is permanent and has a downtime of 7 - 14 days. It is advised to undergo rhinoplasty with a certified and experienced plastic/cosmetic surgeon. In your case, if you desire a smaller nose, width reduction rhinoplasty is advisable as it will reduce the size of the nose bridge and nostrils.
