Thanks for your question and as always, we recommend that you have these injections done by a board certified dermatologist or plastic surgeon that are skilled in this technique. Fillers at the tip of the nose need to be injected very carefully and as noted, by skilled injectors, to avoid any potential complications. A little bit of filler usually goes a long way and on occasion, they do not last as long as we might want. but safety is the key and you need have someone overdue things so if you need repeat injections, which is not really the norm, then that is what you may need. Having more robust fillers also can be used, but again, safety is the most important thing in this area. Find the right injector and you will do just fine.
