What area of the nose are you trying to treat with botox? Typically the frown lines or "11" lines 15-25 units are used in women. If you are talking about the lines that form when you smile or express on the dorsum of the nose, they are referred to as "bunny lines," only a 2-6 units are needed. But if you are talking about nasal reshaping, which I do frequently on the nasal dorsum and supratip, you would need a filler and I suggest using an hyaluronic acid (HA) typic filler that can be reversed if you are unhappy or if a complication were to occur. Good luck, Dr. Emer.
Thanks for your questions. It is unclear what you are looking to treat. If you are thinking about treating the "bunny lines" which occur when you scrunch your nose, generally 5-10 units of Botox on each side of your nose is usually sufficient for a natural result.Good Luck
