54 year old female & always had small dent on nose but it's gotten worse, what can I do? (Photo)

Hello, hope you are well. I have corrected noses exactly like this. The concavity--or 'dent'--is generally caused by buckling of the lower lateral cartilage underneath the skin. It can be fixed with rhinoplasty, and requires cartilage grafting to support the buckled area (either from the nasal septum or ear). At the same time, any other aesthetic modifications to the nose that you may desire can be performed.
Cheers,Dr. Tower

Hello! Thank you for your question.You have a huge deviation, this can cause breathing problems, I recommend rhinoplasty surgery to get rid of this image and gain a healthier nose.If you can provide photos with better lighting, from the side of your face and 1 meter away I would be able to make a proper evaluation. It would be more convenient to decide with face-to-face consultation. Best regards!

The photo shows a concave curvature of the right side of the nose. The best way to fix that is with surgery which could straighten it permanently. If surgery is not an option, a filler may be able to smooth it out some as well. Be sure to see an expert rhinoplasty surgeon for consultation.
