Hello dear,
Thank you for sharing your concern with us and trusting your issue to professionals.
Based on the pictures you have provided I would say that refining and changing the shape of your nose is quite achievable. Firstly I would like to assure you that your nose isn't big according to the propotion of your face and other facial features. But if you still feel unhappy with the looks of your nosemyou can undergo a rhinoplasty. I believe that a narrowing of the nose bridge and some nose tip elevation and refinement procedure will for sure help you get the results you desire. The thick skin “problem“ might limit you from having a very tiny and narrow nose, but it doesnt mean that you can’t have a slimmer and prettier nose. In any case, you will have to get an appointment with a good surgeon who has performed many rhinoplasty operations before and decide together on the shape you want and suits you better. Personally I have had a lot of patients sharing the same problem with you who have met their dreams after undergoing rhinoplasty.
Hope you find this information helpful.
