According to your description, what you should do is silicone rhinoplasty. It is not advisable to raise or lengthen the nasal tip with silica gel, which will increase the tension of the nasal tip skin and make the nasal tip skin white. After a long time, the skin will become thinner and seriously wear the skin. It is recommended to take out the silica gel and use autologous cartilage as the tip of the nose. This is the safest and best method, and there is no need to worry about complications.
