Why my nose droops when I smile? Is it normal? (photos)

Thanks for the question. The muscle listed above is the reason that your nose drops when you smile. It is a very common issue, but some people have more pronounced function than others. It can be difficult to treat as cutting this muscle during surgery can lead to unwanted effects. Botox is another option and might be more reasonable as the effects are temporary. I have not heard of any physical therapy or exercises to treat this issue, but I'm sure it can't hurt. Good luck!

It is not uncommon for the nasal tip to droop when you
smile. You could benefit from having the
overall length of your nose reduced and brought closer to your face, as well has
have the tip supported with a vertical cartilage graft to the columella.

This added support will prevent the nose from pulling down
with smiling. In addition, often times  we surgically detach the nasalis muscle that stands out over the upper lip
bone and when contracting pulls the tip down.
The combination of detaching muscle and providing tip support with a
cartilage graft improves the appearance and takes away the tendency for the
nasal tip to droop when smiling.
