is there a certain point where to inject for bunny line?

When Botox is injected to treat the bunny lines of the nose, it is injected directly into the area of the lines. This is not near the mouth area. I have never had a patient had their smile affected by treating the bunny lines with Botox.

Using Botox as an injection to relax muscles at the top of the nose will help in reduction of wrinkles in that area. The area injected is the nasalis muscle which will not affect your smile. The small wrinkles will smooth out with a few units on each side and is a safe area for Botox injections.
