Please tell Me there's a way to reverse Sculptra...?

The effects of Sculptra cannot generally be reversed. Other fillers can usually be used to fix what you do not like from the Sculptra treatment. I suggest visiting your injector, or a new one if you are unhappy with their service, in order to get a personal evaluation. 

There is really not a way to reverse Sculptra.  You would need to be examined or pictures of you would be needed to determine what your options might be to improve the issue under your eyes.  I do not recommend using Sculptra under the eyes, as it can cause visible bumps there at times.  It is possible that a hyaluronic acid filler, like Restylane, could be used under your eyes to improve the appearance.  

I'm truly sorry for your
unfortunate experience. Unlike some fillers, however, Sculptra's effects cannot
be reversed because it works by triggering collagen growth. It may be possible,
though, to compensate for the appearance you describe. I can't recommend a
specific treatment without seeing photos or examining you, but Restylane® in
general is an effective filler around the eyes. Best wishes.
