Hydrocortisone to thin thick bulbous nose tip?

Hi -- I hate my wide, bulbous nose, but understand that due to my thick nose skin that I may not be a good candidate for rhinoplasty, and wouldn't be able to achieve the results that I want. I recalled that a dermatologist once told me to use hydrocortisone cream for my cystic acne, but to use it sparingly because it can cause the skin to thin. Could I apply the hydrocortisone to my nose tip to thin the skin and tone down the bulbousness? What's the worst that could happen? Thanks!
