Thank you for your question. A Rhinoplasty - or nasal surgery - would be able to reduce the tip of your nose. Your tip seems to be uneven from these pictures, and a Rhinoplasty could address the unevenness as well as improve any breathing or functional problems that you may have as well. Please consult with your board certified facial plastic surgeon.
Fillers or Surgery for Nose
Fillers will add volume, so that would not help reduce the size. My best suggestion is to seek a board-certified plastic surgeon and to have a consult to determine if you are a good candidate for surgery. There are indeed procedures that can be done to reduce your tip size, and they can be done with a closed surgery if the surgeon is experienced.
