Eyelid Trouble After Sculptra on Cheeks and Temples

It is unlikely that Sculptura injection would cause permanent nerve damage.
Sculptura does work by causing a local inflammatory reaction and recruiting fluid which occupies space.
It would be unusual to have effects lasting longer than the effects from the local anesthesia that may have been used with the procedure. If you have symptoms lasting more than 24hrs you should discuss this with your treating provider.
I hope this helps.

It is possible that the lidocaine (local anesthetic) in the sculptra was infiltrated near the nerve that helps to close the eye. Most often this wears off in 3-4 hours. Less likely is if the needle accidentally passed through or transected the nerve. That is very unlikely. I would see your original doctor to see what the problem is exactly. It may be completely unrelated to the sculptra. 

It is unlikely that the Sculptra itself caused any dysfunction of eye lid movment. More likely, it was the effects of the local anesthetic that was mixed with the Sculptra. At 3 weeks, if you feel heaviness, it maybe from the product being injected very close to the eyelid, and residual swelling around the material.

The most likely explanation for the scenario that you describe is that the anesthetic mixed in the Sculptra probably temporarily paralyzed the muscle that closes your eyelid. The fact that you can completely close your eye means that there is no nerve damage. The heaviness that you are feeling may be swelling or the collagen that is being produced in response to the Sculptra. If you have any concerns you should contact your treating physician. Good luck!
