Can the nose become larger/more bulbous with age?

hello thank you for your question and provided information as well... based in your question and the picture you showed you are a good candidate for rhinoplasty , in your case with technique open and elevate the tip.

Thanks for the question. Yes, noses can become more bulbous over time as cartilage can shift and change the appearance of the nose. In many cases, rhinoplasty or nose reshaping surgery can be used to reverse the changes and restore a more youthful look to the midface. Make sure you work with a board-certified plastic surgeon with extensive experience in rhinoplasty, as this procedure requires precision, expertise and an artistic eye to create a look that is natural and proportionate to the rest of the facial features.

Short answer -- yes... but this is not an absolute.  Cartilage growth varies, and noses and ears, composed of a significant amount cartilage may grow with age... With the nose specifically, the tip may lose some refinement and droop.  Regardless, based on the photographs you posted on your other question, I think a tip rhinoplasty would benefit you and set your mind at ease about any possible nose growth in the future...Good luck.Dr Markarian
