It is possible glabellar Botox changed the appearance of my nose?

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

If the injected Botox was as you described it should not affect the tip of your nose. I encourage you to visit with your injector to discuss your concerns.

This is a highly unlikely scenario. Nose drooping when you smile can be caused by the depressor nasi muscle which is a small muscle just under the columella. This muscle is typically not affected by injectables performed in the upper 1/3 of the face. It can be corrected during an open rhinoplasty by surgical manipulation, but is typically not treated by injectables.
