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.
