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.

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.

Lumps were more common among early days of Sculptra when the dilution was not standardized. After few years of trials and few errors, new dilution protocol has been standardized by advanced physician injectors and Sanofi-Aventis to minimize lumps. Injection of Sculptra with the new diliution can be performed either subcutaneously or along periosteum (just above the bony structure of the face/skull). The rule of the thumb is never inject Sculptra above orbital rim, though it can be injected near orbital rim and be massaged upwards with precision by a qualified and trained board-certified dermatologist or plastic surgeon.
