Why Was Sculptra Injected Directly into Bone?

Your doctor did not inject the Sculptra into the bone! They might have injected it right above the periosteum which is a thin connective tissue layer that is tight and covers the bone. When Sculptra is injected it is not uncommon, despite its dilution, that bumps can form.  Sculptra is a great volumizer but we have learned over the many years since inception, that a larger volume of dilution means less chance, but not zero, of lumps to form. A bump might be improved with the injection of saline or local anesthetic into the lump and then vigorous massage.

I have never heard of Sculptra being purposefully injected into the bone.  There may be a miscommunication in that Sculptra may have been injected just above the bony ridge near the eye.  Once a bump forms it can take several years to resolve.  Various techniques have been tried to dissolve the bumps but time is the best healer.  Surgical removal is not  the first choice because the problem although frustrating will eventually resolve on its own.

Lumps from Sculptra are mainly due to injection technique and depth of injection.  The injections are not into the bone, but right above the bone.  Sculptra is a semi-perminent filler, meaning that it takes a long time to go away.  Other fillers such as Juvederm last around a year but then need more frequent injections.  Sculptra is a great product to replace lost volume in the cheeks, temporal region, nasalabial crease and along the jawline.  Good luck.
