Can I wear a nose clip at night or even just an hour a day or would that have any negative side effects? (photos)

I would advise against using the nose clip until having it inspected by your surgeon.  Allow your surgeon to inspect the device and your nose to see if it may have any therapeutic benefit. The larger appearance to the tip of the nose is likely due to swelling that will gradually settle on its own. 

I would not recommend it as we are unclear about all the surgical maneuvers used by your surgeon to make the tip etc. 

Dear Irinaaa, I would not suggest using a nose clip ever and even more so not when you are still early in the recovery phase at approximately 60 days post surgery. Contact your surgeon's office for a follow up appointment  and bring the device with you if you have already purchased it. I  am sure you will get the same response of "NO" to the clip.
