The best answer to your concerns could be given after an in person consultation, where the structure of your bones, strength of your cartilage and thickness of your nasal tip skin could be evaluated. Having said that, from your photograph, it appears you have relatively thick tissue at the tip of your nose. In order to raise your tip, additional support would be required to project your nose, slightly forward and upward to correct its drooping. This is usually done by using a piece of cartilage from your nasal septum to add additional support underneath the nasal tip. As the nasal tip gets projected forward and upward, it usually slightly elongates your nostrils. Discuss this in detail with your plastic surgeon.
