There is a small indentation on the tip of my nose. Could it be fixed with a filler? (Photo)

Hi Thank you for your question A filler here would be a good option and this can subtly improve the indentation and address the contour discrepancy you currently have. I hope this is helpful for you BWRohit Seth Plastic, reconstructive, aesthetic and hair transplant surgery

If one has a depression after Rhinoplasty, it can be filled with a hyaluronic acid filler
such as Restylane or Juvederm. It works very effectively and can last well over a year. This
should be done in the hands of a Board Certified Plastic Surgeon or Dermatologist with expertise in this area.

You appear to be a good candidate for a non surgical rhinoplasty--things such as the injection of fillers, microneedling and/ or laser treatment should give you a nice improvement. Obtain a consultation with a board certified plastic surgeon in your area to discuss further.
