Can Botox be used to make your nose thinner?

Botox injections will not change the thickness of the skin of the nose. It won't affect the oil glands although it can diminish sweating But it won't thin the dermis.

Botox will not make your nose appear thinner.  Botox works by relaxing facial muscles of expression that cause wrinkles.  Sorry, but Botox is not the product to improve this particular problem.
