Your nose has great symmetry, and the structure proportionally suits your face very well. If you are uncomfortable with the way your nose looks, I would recommend leaving your bridge alone. If you were looking to change the bottom of your nose without much or any change to the bridge, you could look to have a tip rhinoplasty. Tip rhinoplasty is less invasive than rhinoplasty, and can sometimes be performed without general anesthesia, so it can be a much less expensive surgery compared with standard cosmetic rhinoplasty procedures. You have a slight bulge around your tip that could be reduced with tip rhinoplasty, but you may find non-surgical rhinoplasty could work just as well for you. Non-surgical rhinoplasty uses fillers to add shape and definition to the nose, but unlike surgical rhinoplasty which is permanent, the results only last a year or two. It is difficult to say for sure, judging from these photos alone, but considering that your nose is not large, you might find satisfaction with some injections around the tip to smooth out any bumps and possibly near the radix between the eyes to restore balance. These procedures range in price. Standard cosmetic rhinoplasty with anesthesia often cost $7000+, while tip rhinoplasty ranges from $3500+. Non-surgical rhinoplasty ranges in price depending on how much fillers are used, which in your case would probably be a small volume. You might expect to pay $800-2000 depending on many factors.
