Is Scuptra proper filler for under the eyes?

Because Sculptra is small particles of poly-L-lactic acid, it's not usually used in the areas where there are circular muscles, like the lips and around the eyes.  The circular muscle may tend to push the Sculptra particles out and form nodules.

The cheek is a perfectly fine area to fill with Sculptra, even up higher on the cheek as long as the eyelid itself is not filled.

Usually the edema that results from Sculptra injections is transient, lasting several days.  I also have my patients do a fairly vigorous massage of the injected areas for 5 minutes 5 times a day for 5 days.  That helps distribulte the Sculptra particles evenly.

Icing the area for 5-10 minutes every two hours may help, taking care not to overcool the delicate eyelid areas.

For directly under the eyes (within the bony orbit area) usually a hyaluronic acid filler is used. Sculptra can be placed there but must be small amounts and very dilute because the action of the muscles in that area tends to push the particles together more than other areas so the area is at greater risk for lumps. Sculptra is great on the cheeks. It does not sound like you are having any lumps in the area and probably the puffy and swelling is just temporary and will go down. Massage may help the swelling and will help prevent any lumps or bumps from developing.
